The news headlines:

• Introducing the RSGB’s team of young radio amateurs for YOTA Paris
• The RSGB celebrates International Women in Engineering Day
• The RSGB Exam Standards Committee publishes its annual report

The RSGB has announced the team of young members who will be representing the Society at this summer’s Youngsters on the Air camp. The event, hosted by the French national amateur radio society and the IARU, will take place at the historic Château de Jambville near Paris between August 18th and 25th. The team is comprised of team leader Leon, 2E0VUF, and team members Sophie, M7IJG, and Emily, M7HPU. You can read more about the camp and the team on the RSGB website at rsgb.org/yota-camp

The RSGB knows that amateur radio is a great foundation for careers in Science, Technology, Engineering and Mathematics, or STEM as it is often known. That’s why, for International Women in Engineering Day tomorrow, Monday the 23rd of June, the Society is sharing stories of female radio amateurs involved with STEM. From a young radio amateur who was inspired by an ARISS contact, through to a Professional Transmitting Engineer at Woofferton Transmitting Station, each one of them has a love for amateur radio and STEM activities and the career opportunities they present. Read more about them on the RSGB website at rsgb.org/inwed. The Society will also be sharing the profiles on its X and Facebook pages throughout the day tomorrow, the 23rd. Get involved by liking and sharing these motivational stories.

The RSGB Examinations Standards Committee, or ESC, has published its annual report, relating to activities in 2024. The report shows that overall candidate numbers have increased to above pre-pandemic levels and are well above the extrapolation of the declining trend over the decade before the pandemic. The ESC believes that this is probably due to the availability of remote invigilation for online examinations taken at home and the increase in provision of distance learning courses, making the hobby much more accessible than in the past. You can read the full report on the RSGB website by going to rsgb.org/esc and choosing the ‘Minutes, papers and reports’ option in the right-hand menu.

Whether you are just starting to learn Morse code or are already an experienced operator, the GB2RS Morse Practice web page is just what you need to brush up on your skills! Created by GB2RS Newsreader Graham, G4JBD, you can select different sections of the latest RSGB news, which are then played in Morse code at the pitch and speed of your choosing. What makes this resource unique is that you can also add in different degrees of man-made noise and natural band noise, which gives you a very realistic experience of copying Morse code under poor propagation or contest conditions. Graham has recently updated the page with more options. One of these is the Farnsworth timing, which can play the individual characters at a selectable speed while allowing separate adjustment of the gap between the characters. The new version works well on smartphones and displays the text with a real-time pointer as the Morse code is sent. The GB2RS Morse Practice page can be found at tinyurl.com/gb2rsmorse

Bath Based Distance Learning’s next Full licence course runs from August to December, with exams in January.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 19th of June 2025.

Last week, we mentioned a large coronal hole on the Sun that might cause problems. The hole is so large that it is still Earth-centric seven days later.

We had expected the hole to increase the Kp index due to the solar wind emanating from it. However, as of Thursday, the 19th of June, conditions remained quiet with a Kp index of 2. As geomagnetic conditions have remained calm this past week, it has been quite good for HF.

15m has been one of the better bands, with openings to both the east and west, depending on the time. As is the way nowadays, most of the activity has been on FT8, but it has opened up opportunities to work the Far and Middle East, as well as South America.

The solar flux index has generally been in the range of 130 to 150, with a peak of 161 on the 15th of June. The Sun has been active, with a near X-class solar flare being observed around sunspot region 4114. This peaked at 1805 UTC on the 15th of June. There was also an X-class solar flare at 21:49 UTC on the 17th of June.

This latter event was late in the evening, so it had little impact on the UK, other than to potential paths to the west.

Maximum usable frequencies, or MUFs for short, declined a little during the past week, with openings on 21MHz becoming a little scarcer. It is useful to operate as close to the MUF as possible to minimise the effects of D-layer absorption and maximise the chances of working DX.

Next week, NOAA predicts the solar flux index will be in the range of 125 to 145. Unsettled geomagnetic conditions are forecast for the period from the 24th to the 27th of June, with a maximum predicted Kp index of 5.

If the Kp index is low, then we have a good chance of 21 MHz openings to South America in the evening. As we pass the summer solstice, we may even expect 14 MHz to remain open to DX throughout the night. We can also expect Sporadic-E to continue to provide short-skip openings on 28 MHz, and even the lower HF bands, such as 14, 18, 21, and 24 MHz.

And now the VHF and up propagation news from G3YLA and G4BAO

After a week of high pressure, this weekend returns to something more normal with showery rain and a series of weather fronts and showery interludes in the coming week. This will mean that rain scatter on the GHz bands is worth considering. Also, since we are into the summer season, the chances of some rain being heavy and thundery is a good signal for rain scatter.

This sequence of low-pressure weather suggests that high pressure and Tropo will be less likely to make a big impact on the coming week’s operating log. Any sign of high pressure will tend to be towards the south of the UK and over the continent. In very hot weather, the conditions can be good for low-level surface ducts across cooler seas. So, if you are tempted, then go for coastal or maritime paths up the east coast or across Biscay, for example.

Meteor scatter may benefit from the late June Bootids, which peak on Friday, the 27th of June and the daytime Beta Taurids, which peak on the 28th of June. These are small showers, but they can also be important for contributions to long-lived metallic ions, which are the building blocks of Sporadic-E propagation.

Aurora continues to appear with occasional radio events, but there is too much daylight for anything visual. As an alternative, you might see glimpses of noctilucent clouds low down on the northern horizon. These form in the mesosphere, at about 80km, as ice crystals form on meteor dust and can exhibit complex wave patterns. These are both good omens for Sporadic-E.

The summer Sporadic-E season is well underway now. It is advisable to check the usual cluster maps and the propquest.co.uk website for daily updates. It’s also worth making use of the longer daylight and weather patterns over the polar regions for paths to the Far East.

The Moon reaches perigee, its closest point to Earth, tomorrow, the 23rd, so path losses are low. Moon declination also reaches a maximum positive value on the 25th of June. This will mean that there are long Moon windows. 144MHz sky noise is moderate, increasing to high by tomorrow, the 23rd. The New Moon is on the 25th of June, so expect high noise levels due to its proximity to the Sun.

And that’s all from the propagation team this week.

GB2RS News

Sunday, the 15th of June 2025

The news headlines:

• Book now to secure your place at the RSGB 2025 Convention
• The RSGB launches the “SES Cookbook”
• The RSGB Operating Advisory Service issues advice

The RSGB annual Convention is a fantastic opportunity for radio amateurs to meet, learn and share experiences. Whether you’re newly licensed or have years of experience, there is always more to discover. That’s why the Society is excited to introduce this year’s theme: “Discover, Learn, Progress”. Whether you want to discover something new, learn more about a particular aspect of amateur radio, or progress and develop your skills, you’ll find something at the Convention to explore and enjoy. The prestigious event will take place between October 10th and 12th at Kents Hill Conference Centre in Milton Keynes. Book now to secure your place in joining like-minded people for what is also one of the best social events in amateur radio. Take advantage of the early-bird prices by going to rsgb.org/convention. The Society is delighted that the event will be sponsored again by Martin Lynch and Sons.

Special event stations are popular around the world and a great source of fun and excitement for organisers and QSO chasers. They can also be a fantastic tool for outreach, allowing you to demonstrate amateur radio and encourage people to find out more. But how do you organise an event to achieve all those objectives? The RSGB has just launched a new web section that focuses on special event stations. For RSGB members and Affiliated Clubs, there is an online guide called the SES Cookbook, which offers a wide range of practical guidance to help you deliver the best experience for your visitors and the organisers. The guide covers a wide range of topics, including how to apply for a special event station callsign, the stages of the planning process, publicising your event to attract visitors and how to make a good number of contacts. For non-RSGB members, there is a simple guidance document that outlines the main things to consider when planning this type of event. The new section also draws together existing information about permanent special event stations as well as QSL guidance. If you’re planning an event for this year, or even for next year, now is the time to make the most of this comprehensive guide. Go to rsgb.org/ses to find out more.

The RSGB Operating Advisory Service, or OAS, provides advice to members on dealing with situations that are not within the spirit of amateur radio. From time to time, this activity goes beyond what is classed as acceptable behaviour and requires action to be taken. In these circumstances, the OAS recommends reporting the matter directly to Ofcom and to the police in the case of issues which could be classed as harassment, stalking or hate crimes. Experience has shown that this carries more weight coming directly from the people hearing or suffering the problem rather than a third party, such as the RSGB. If you hear anything that is not acceptable behaviour, contact the RSGB OAS first, and the team will suggest the correct course of action. Once Ofcom and the police have issued reference numbers, these should be passed to the Operating Advisory Service. You can contact OAS via oas@rsgb.org.uk

The RSGB has submitted responses to a pair of Ofcom consultations. The first considered a series of licence exemption updates, including arrangements for some visiting radio amateurs to the UK. The second concerned filing procedures for the growing number and variety of satellites. Both replies were developed by the RSGB Spectrum Forum, drawing on its members’ wide breadth of expertise. The Spectrum Forum expects that there will be further updates to both topics. Find the full replies by going to rsgb.org/spectrumforum and selecting the ‘Papers and Consultations’ option from the right-hand menu.

The RSGB recently announced two new volunteering opportunities. The RSGB CW Champion will help the Society in taking Morse code to new audiences. Tasks will vary from developing the CW content on the RSGB’s website through to developing and supporting a team of enthusiastic individuals who can support CW-related activities. The second role requires an individual with experience in science, technology, engineering and mathematics. The RSGB STEM Champion will help the Society to reach new audiences, build relationships with related organisations and encourage more young people into STEM careers. Go to rsgb.org/volunteers to read the full role descriptions and learn how to apply.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 12th of June 2025

Propagation was a mixed bag last week, with occasional Kp index rises but a solid solar flux index, which hit 141 on Thursday, the 12th. We also had some sporadic-E short-skip conditions on the HF bands, which brought some surprises.

We are now in June, so the summer HF doldrums are well underway. But that doesn’t mean that the fun has gone from the HF bands. Daytime maximum usable frequencies over a 3,000km path have been around 18 to 20 MHz, so the main active band has been 20m.

Paul, GM4ULS, reports that there was a spectacular inter-G event on the morning of Tuesday, the 10th of June. Whilst activating special event station GB70RS from Perth, he worked a mini pile-up of English stations from anywhere between Southampton and Manchester. This was between 0949 and 1022 UTC on 14.210 MHz. He said it sounded like the 40m band at times!

We think this was probably a Sporadic-E event, which often creates strong but short-lived paths across the UK on the HF bands in the summer. We normally think of Sporadic-E as affecting the 10m band, but the lower bands are also often implicated. Have you worked anything unusual via Sporadic-E? If you have, please send your reports to radcom@rsgb.org.uk

Otherwise, DX on the HF bands has been a little sparse, with paths opening to South Africa and South America on the 20 and 17m bands at times. Perhaps this is a good time to work some Summits on the Air or World Wide Flora and Fauna stations in Europe. These are usually QRP stations that appreciate your contacts.

Next week, NOAA predicts the solar flux index will be in the 120 to 130 range. Unfortunately, geomagnetic conditions are predicted to be unsettled, thanks mainly to the return of a massive coronal hole on the Sun.

Disruption was due to start around the 14th, but due to the hole’s size, this could continue for at least three days with a maximum Kp index of 6. Expect the HF bands to be disrupted with lower maximum usable frequencies as the plasma in the solar wind hits the Earth. It may be a good time for visible aurora hunting, though.

And now the VHF and up propagation news from G3YLA and G4BAO

The high summer conditions have brought an increasing chance of Sporadic-E, particularly on digital modes, with DXmaps.com plots showing plenty of paths on most days.

Many of these are possibly associated with turbulence generated by jet streams in the weather part of the atmosphere. These send atmospheric gravity waves upwards to affect the E region.

It's this association with specific weather features that makes Sporadic-E sporadic in a geographical sense. If so, in the coming week, the jet streams are mainly over the northern fringe of Europe. These suggest a better chance of paths to Scandinavia with fewer options to the south to support paths to the Mediterranean and the Balkans.

In any event, June is high season for Sporadic-E, so remember to check the 6m band either mid-morning or late afternoon.

The early thundery weather at the end of last week was useful for rain scatter on the GHz bands, and it is just possible it will return for the end of the coming week.

In between times, it will be a high-pressure story that will dominate and may well produce some useful Tropo conditions. However, note that in the hot days of summer, inversion conditions and Tropo will be better at night and tend to weaken by the middle of the morning.

Meteor scatter will have been boosted by two showers on the 7th and 8th of June, and, since they were broad peaks, there should be some meteor input left to see us through the coming week.

For EME, sky noise is dropping. Low declination is now starting to decrease. So, Moon windows and peak elevation are improving. EME conditions are classed as poor to moderate today, the 15th of June, but are then good on the 21st and 22nd of June.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 5th of June

Last week’s HF propagation was heavily influenced by unsettled geomagnetic conditions. This was caused by a combination of coronal mass ejections and a strong solar wind from a coronal hole.

The coronal mass ejection, or CME for short, followed a solar flare from sunspot 4100 on the 31st of May at 0005 UTC. The explosion lasted more than three hours. Type 2 radio emissions from shock waves within the CME cloud suggested it was travelling at 1,938 kilometres per second, or 4.3 million miles per hour!

Eventually, the Bz swung south. This meant that the interplanetary magnetic field more easily coupled with the Earth’s magnetic field. The result was that the Kp index got up to 7.67 on the 1st of June.

The auroral effects were reported as being due to a co-rotating interaction region, or CIR – a region in space where fast and slow solar wind streams collide, creating a compressed area with enhanced plasma and magnetic fields.

The Kp index was 7 or more for four three-hour periods. This pushed the maximum usable frequency over a 3,000km path below 14 MHz at times, which wasn’t conducive to good DXing.

On Thursday, the 5th of June, it looked like we were past the worst, and the Kp index was back to a more reasonable 2.33.

Meanwhile, the solar flux index declined from a recent high of 164 on the 31st of May to a low of 134 on the 5th of June. HF propagation was being driven by the geomagnetic conditions, with a general lowering of the maximum usable frequency.

Next week, NOAA predicts that the solar flux index will start the week at around 155 and remain around 150. More worryingly, geomagnetic conditions are again predicted to be unsettled after this weekend, with a maximum Kp index of 6 on the 13th of June.

So, unsettled geomagnetic conditions, plus the HF summer doldrums, mean HF DX via F2-layer propagation may be hard to find. So, make the most of the 10m Sporadic-E short-skip openings instead!

And now the VHF and up propagation news from G3YLA and G4BAO

Last week offered an example of what a good Sporadic-E season should look like. On Tuesday, the 3rd of June in particular, the 6m band sounded like the 20m band and, at its peak, activity extended all the way up to the 2m band.

This coming week has an unsettled flavour with several areas of low pressure and weather fronts involved, together with heavy showers in between. This means rain scatter will be a supported mode on the GHz bands.

There is a slight hint of a slow improvement during the week, but not really any high pressure showing up until right at the end of the coming week. So, there is a chance of Tropo propagation for the 2nd 144MHz Backpackers Contest on Sunday, the 15th.

Meteor scatter is always interesting in June, with four showers to play with during the month. The early ones are the Arietids, which peaked on Saturday, the 7th of June – good news for the 50MHz UK Activity Contest on Thursday the 12th.

The Zeta Perseids peak tomorrow, the 9th of June, and there will be a couple of other showers later in the month. This is probably also why the Sporadic-E prospects improve about now.

Aurora has also been much in evidence recently. Despite the light summer evenings and short nights, the chances of radio aurora continue to be important, so monitor for high Kp values above about 5.

The advice for some who have not yet worked Sporadic-E is to check the 6m band around teatime.

There are, of course, usually two primary periods when Sporadic-E is more likely: one in the morning, and the second in late afternoon and evening. A morning opening may repeat in the afternoon in similar locations, although usually the weather trigger may have moved a little in the meantime.

Check the jet stream charts at propquest.co.uk by following the Sporadic-E blog tab. The daily commentary will highlight the important directions each day. You can hopefully test out the system on Thursday, the 12th of June, in the 50MHz UK Activity Contest.

EME path losses were at their maximum with apogee, when the Moon is at its furthest from the Earth, on Saturday, the 7th of June. Declination reaches a minimum on Wednesday, the 11th, so Moon windows are short and peak elevation is low. 144MHz sky noise peaks around the 11th and 12th of June. EME conditions were classed as poor this weekend and are classed as poor-to-moderate on the 14th and 15th of June.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 29th of May 2025

Last week’s high-speed solar wind, from a massive coronal hole on the Sun, took its toll on the HF bands. However, this week has been little better. Another coronal hole running diagonally across the Sun has been emitting particles that have pushed the Kp index up to a maximum of 6.67 w,hich puts us into visible aurora territory.

Nevertheless, some DX has been worked, including CP4BT in Bolivia, ZP5KP in Paraguay and V44KAI in St Kitts and Nevis. These were reported by Karl, G0SKW on the CDXC Slack alerting system.

BA100IARU, a special event station celebrating the 100th anniversary of the International Amateur Radio Union, has been active from Beijing, China and has been worked on 20m CW. The station’s QRZ.com page provides real-time updates on which band the operators are working on.

Most of the DX has been worked on 21, 18 and 14 MHz, with the 10m band mostly closed due to the summer doldrums. There have not been too many Sporadic-E openings on the 10m band. Instead, most of the Sporadic-E reports have been on the 6m band.

The solar flux index has increased, standing at 144 on Thursday, the 29th of May, which is always a good sign. The solar disk is looking quite healthy at the moment with spots in both hemispheres.

As of last Thursday, the 29th of May, there had been 43 C-class flares over the previous five days, as well as six more potent M-class events and one X-class flare. So, the Sun is still very active.

Next week, NOAA predicts that the solar flux index will reduce again, perhaps going as low as 110 by Wednesday, the 4th of June. It does look like we are in for a rough ride with unsettled geomagnetic conditions forecast for the coming week. Looking further ahead, the 13th and 14th of June seem to be the worst days, when a Kp index of five is forecast.

As usual, a high Kp index can result in lowered maximum usable frequencies and aurora-like conditions, with a slow recovery.

And now the VHF and up propagation news from G3YLA and G4BAO

The weather continues to be unsettled into the coming week, especially for northern areas, but with some drier and warmer spells in the south.

There do not appear to be strong signs for any Tropo success, but there should be a chance of occasional rain scatter on the GHz bands. Some models suggest we are on the edge of high pressure over the North Sea. Others drive a deep low right across the country. This will resolve itself next week, but for now, it's not at all clear which forecast will win through.

The prospects for meteor scatter are mostly random meteors, but towards the end of this wee,k the daytime Arietids will peak to enhance chances further.

The solar auroral alerts keep coming, so it's reasonable to expect the chance of some radio response, such as watery-sounding signals on HF, even if we don’t go to the full effects on VHF. It’s certainly worth watching for those increasing Kp values.

The Sporadic-E prospects often burst into life about now. So, after a few reasonable 6m band openings, like the one into southeast Europe on Wednesday the 28th, make sure you are ready for the first week in June – one of the prime weeks for Sporadic-E opportunities.

This is partly due to meteor input and the fact that the tidal winds in the E region are taking on their summer pattern. The long polar days mean that the low-pressure weather patterns are also beginning to affect the northern polar routes to China and Japan across northern Russia, with their possible weather triggers, like jet streams.

EME path losses are increasing again. Moon windows shorten, and peak elevation is falling as the Moon's declination goes negative again on Wednesday, the 4th of June. 144MHz sky noise is low and remains low as the week progresses.

And that’s all from the propagation team this week.

GB2RS News

Sunday, the 25th of May 2025

The news headlines:

• Apply to become the RSGB’s new CW Champion
• The Tonight@8 series continues in June with Morse code
• Could you be the RSGB’s new STEM Champion?

As part of the RSGB’s ongoing strategy to take amateur radio to new and diverse audiences, it is seeking to appoint a volunteer CW Champion. Whilst the need for a CW test has been removed from the licensing requirements, there is still a strong interest in the mode. Recent communications and activity involving Morse have received high levels of interest, and the Society would like to do all it can to encourage and promote CW within the hobby. This new role will take the lead with activities including managing RSGB web content relating to Morse code and contributing to the GB2CW broadcasts. The volunteer will also be tasked with building a team of enthusiastic individuals who can support CW-related activities undertaken by the Society. This role is intended to help take Morse to new audiences with an emphasis on learning and development to further the skills of RSGB members. Read the full role description, as well as details of how to apply, by going to rsgb.org/volunteers

The next webinar in the Tonight@8 series is on Monday, the 2nd of June. The RSGB’s Morse Test Coordinator, Eric Arkinstall, M0KZB, will lead the webinar and will be joined by a panel of Morse experts, including RSGB Morse Assessor and GB2CW broadcaster Michael Topple, GM5AUG. The presentation will include an introduction to Morse, how to start learning the code, the different types of Morse keys and the Achilles heels that can occur when learning Morse. There will also be a panel discussion on how they each became interested in the mode and how they overcame any problems they have encountered along the way. Find out more about this and future webinars on the RSGB website at rsgb.org/webinars

Would you like to become the RSGB STEM Champion? This new volunteer role is part of the Society’s strategic plans to encourage more young people into STEM careers and to demonstrate the contribution that amateur radio can make to those careers. The focus of the role will also be to develop and strengthen the Society’s relationship with the STEM Learning organisation. The Champion will need to work closely with licensed STEM Ambassadors, attend STEM events to promote amateur radio, and support radio amateurs who would like to become STEM Ambassadors. The STEM Champion will work closely with the Board Liaison, Ben Lloyd, GW4BML and members of the RSGB Outreach team. To make the most of the role, you will need to have the right skills and experience. This includes being a STEM Ambassador with involvement in the STEM sector, and also being proactive, enthusiastic, organised and willing to find new ways to achieve the role’s objectives. For full details of this challenging but rewarding role and how to apply, see the RSGB website at rsgb.org/volunteers

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 22nd of May 2025

A high-speed solar wind, originating from a massive coronal hole, took its toll on HF this past week.

During the weekend of the 17th and 18th, the Kp index was above four for nine of the three-hourly recording periods. Unfortunately, the feed from the Dourbes Digisonde failed over this period, so we can’t comment on what effect this had on maximum usable frequencies, or MUFs for short.

Later in the week, geomagnetic conditions improved, despite the coronal hole still being Earth-centric, and the Kp index fell to more reasonable levels, sometimes in the ones and twos.

An M3.2 solar flare was observed at 08:21 UTC on the 19th of May. The source was located off the northeast limb, so perhaps we can expect more as it turns to become more Earth-facing.

Unfortunately, the solar flux index also fell to lower levels, reaching 119 by Thursday, the 22nd. In fact, on that day, it had been below 120 for more than seven days. But all is not lost, as a solar flux of more than 100 is usually enough to keep the HF bands open.

MUFs over a 3,000km path have generally reached 21 MHz and have often peaked at 24 MHz at times. It is quite normal for the F2-layer MUF not to reach 28MHz due to a change in the ionospheric chemical make-up in the summer – the so-called summer doldrums. However, Sporadic-E may keep 10m alive, so don’t write the band off.

Propagation, at the moment, favours paths into the southern hemisphere, although each band can have different characteristics at different times. A quick play with the propagation tool at tinyurl.com/propcharts will show you what we mean.

Next week, NOAA predicts that the solar flux index will remain around 120 until the 27th of May, after which it could rise to 140 by the end of the month. Unsettled geomagnetic conditions are forecast for the period from the 28th of May to the 2nd of June. This could see the Kp index peak at five or six with corresponding drops in the MUF and DX.

As we are now on the downward portion of this solar cycle, we may expect more geomagnetic disturbances from coronal holes and coronal mass ejections.

And now the VHF and up propagation news from G3YLA and G4BAO

The long run of fine settled weather seems to have drawn to a close.

We have a period of changeable and, at times, wet and windy weather to deal with over the coming week. I doubt we will see much, if any, Tropo except perhaps towards the end of the week as some models show a new high building as we move into June.

Before then, the various fronts and showers will bring several spells of rain and a much greater chance of rain scatter on the GHz bands than recently.

The solar conditions have again provided weak auroral events, with fluttery signals on the HF bands being a good indicator, since the bright evenings and early dawns leave little chance of any visual clues. As usual, the measure to follow is the Kp index. So, look out for values of Kp going above five to generate interest.

Meteor scatter is declining as the last of the Eta Aquariids play out, following a long tail from the peak on the 6th of May. Meteors also make up the content of Sporadic-E because, as they burn up, they produce long-lived metallic ions that can be focused into thin layers of Sporadic-E.

There are some less well-known meteor showers in June. So, next week there may be more to say. In the meantime, random meteors and declining Aquariids will have to suffice.

Now, on to Sporadic-E. This is beginning to be the primary mode in these summer weeks. It is sensible to check during main operating windows in the morning, late afternoon and early evening.

Ideally, we require meteor input, a low Kp index, plus some weather triggers to set up atmospheric gravity waves which produce the right wind shear in the E region. Jet streams are usually the best clues for where Sporadic-E might form.

Use the daily Sporadic-E blog on the Propquest website to get an insight of the current day’s weather patterns – see propquest.co.uk

If you have very limited time and have still not worked Sporadic-E, just checking 50MHz in the late afternoon will ensure that you make a start this year.

EME path losses are still falling as the Moon reaches perigee, its closest point to Earth, on the 26th of May. Moon windows and peak elevation are again rising, reaching a maximum on the 29th of May. 144MHz sky noise is low and remains low as the week progresses.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 15th of May 2025

This week, you could be forgiven for thinking that the Solar Cycle 25 maximum is now over. With a reduced solar flux index and an almost blank Sun, there was little to get excited about.

By Thursday, the 15th of May, the SFI was 122, but previously, on the 12th, it had been down to 116, which is the lowest it has been for some time. There is still a lot of solar activity going on, but most of it is not conducive to good HF propagation.

Over the past week, we have had two X-class solar flares and five M-class events. The X-class events were associated with coronal mass ejections, but these appear to have been directed away from Earth. A fast solar wind has resulted in the Kp index standing at four for a lot of the time, namely on the 9th and 10th of May and again on the 14th and 15th.

Unfortunately, this is not uncommon at this point in the solar cycle and adds some evidence that we are now in the declining phase of Cycle 25.

Next week, NOAA predicts that things may improve with the SFI set to rise from the 19th of May. It forecasts the SFI will start the week around 115, but then will climb steadily, reaching 145 by the 1st of June. After a brief rise on the 19th with a Kp of four, things then become more settled with a Kp of two between the 22nd and the 28th of May.

A large elongated coronal hole became Earth-facing on 16th May, which could cause raised K indices and lower MUFs from today, the 18th of May, onwards.

It looks like the best HF F2-layer conditions may occur between the 22nd and 28th of May.

And don’t forget, despite the HF doldrums, we are now well into Sporadic-E season with short-skip occurring, predominantly on 10m. But more of that shortly.

And now the VHF and up propagation news from G3YLA and G4BAO

The prolonged spell of high pressure is likely to remain until near the end of this week, so there is plenty of time to get some more Tropo in the log.

Cloudier and cooler air over eastern Britain at the end of last week may enhance the Tropo by adding moisture under the inversion. For most places, the strongest Tropo conditions will be overnight and early morning, then they will degrade as the daytime heating destroys the surface temperature inversion.

Meteor scatter is declining a little, apart from a few stragglers from early May showers, so it's probably better to keep to the early morning period as your go-to time for meteor scatter to focus on any random input.

Rain scatter is unlikely until next weekend, but it might be worth thinking about the GHz bands from this Friday, the 23rd of May, onwards.

Aurora is a different matter, and the solar activity is likely to keep things interesting as a large sunspot group rotates into an Earth-facing position.

Strong Es opened on Wednesday, the 14th of May, so it's definitely the season to be checking the upper HF and lower VHF bands for Sporadic-E. In this recent opening, the Dourbes ionosonde peaked at an Es critical frequency of 14 MHz, which is a very high value, even for mid-season.

There were strong signals from the central Mediterranean on 6m CW, and some may have even got some 2m digital mode action from the brief opening. Check the Propquest NVIS tab for the day to see the details of this event.

Although weak jet streams were present, the opening may well have been helped by some very intense, slow-moving thunderstorms over France. Remember to start checking on 10m and, if it’s open, look to the higher bands of 6m, 4m, up to 2m.

EME path losses are still falling. Moon declination ended last week at minimum but goes positive again this Thursday, the 22nd of May. Moon windows and peak elevation are again rising. 144MHz sky noise is high this weekend, falling back to low as the week progresses.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 8th of May 2025

Active region 4079 turned out to be not quite so bad as we had predicted. The sunspot was large, about ten times the width of our Earth, so we expected it to be more active. It was regions 4081 and 4082 that produced most of the flare activity last week.

Two filament eruptions also occurred within two hours of each other. The first event began at 16:20 UTC on the 6th of May in the southern hemisphere and was responsible for a plasma wave across the surface of the Sun.

The second filament eruption began in the northern hemisphere around 17:50 UTC to the northeast of AR 4079. A large amount of plasma was flung to the north. The filament eruptions on Tuesday, the 6th of May, did produce coronal mass ejections, but an Earth-directed component was not apparent. So we dodged a bullet!

The solar wind speed remained high for most of last week which didn’t help propagation. It did help to push the Kp index to five across the weekend of the 3rd and 4th of May. Things were more settled later in the week. On Thursday, the 8th of May, the solar wind speed was down to around 500 kilometres per second, the Kp index was three, but MUFs over a 3,000km path were still down at about 20 MHz.

An Earth-facing coronal hole may add to the solar wind this weekend, the 10th and 11th of May. It looks like summer HF propagation is kicking in, with lower MUFs during the day but higher ones at night.

Next week, NOAA predicts that the SFI will be in the range 155 to 165. Settled geomagnetic conditions are forecast for the beginning of this coming week, but unsettled geomagnetic conditions are expected for the 16th to the 19th of May. At that point, we could see the Kp index rise to five again, coupled with poorer propagation and reduced MUFs.

And now the VHF and up propagation news from G3YLA and G4BAO

Tropo has been a key propagation mode during the previous couple of weeks, but there have been variations in the location and timings of these conditions.

Sometimes this will be due to increased moisture below the temperature inversion, so although the cloudier areas have been cool, they have probably done better for Tropo.

This is due to the improved quality of the inversion, which performs better when there is a big moisture contrast across it, as you find with these layers of cloud.

Otherwise, we find that the better conditions are driven by night-time cooling, forming a low inversion near the ground which tends to disperse during the morning as the Sun warms it away. This should still be beneficial for the 70cm UK Activity Contest on Tuesday, the 13th of May, over eastern areas, but perhaps less so farther west.

Good conditions will last into next week, but not everywhere. The main change will see an area of showery rain, possibly thundery, moving north into western Britain this weekend and perhaps some central areas early next week. This raises the prospect of some GHz band rain scatter in the west.

The Eta Aquariids meteor shower peaked last week. In the decaying tail of activity, together with other lesser showers, this should keep an enhanced meteor input for the coming week.

The Sporadic-E season typically runs from May to mid-September and the daily jet stream blogs have started on www.propquest.co.uk.

As usual, the main season offers two periods of activity, one in the morning and the second from late afternoon to the evening. Remember, Es is not guaranteed since it depends upon many factors, but jet streams help, and these are shown on the website maps. Use the map clusters to find out where any activity is starting on 10m and then follow it up in frequency through the lower VHF bands.

EME path losses are at their maximum but falling after apogee on Friday, the 9th of May. Moon declination is negative, reaching a minimum this coming Thursday, so we’ll have very short Moon windows and low peak elevation. 144MHz sky noise is moderate, increasing to high by next Friday.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 1st of May 2025

After the previous week’s geomagnetic disturbances, as described in last week’s GB2RS, the last seven days have been relatively quiet.

The Kp index has mostly been in the ones and twos, however the rise to a Kp value of four on Thursday the 1st of May could herald a return to unsettled conditions.

The solar flux index peaked at 170 on the 24th of April, before declining to 148 at the end of the month. HF conditions have been acceptable rather than outstanding and many stations struggled to work DX at times during International Marconi Day on the 26th of April.

Nevertheless, there is DX about including ZS8W Marion Island, TX9A Austral Islands and HD8G Galapagos Islands.

A look at the Proppy propagation prediction tool will help you work out the best times for making a contact with each station and on each band. You can find it by going to rsgb.org/propagation-tools

Looking ahead, a large sunspot has rotated into view. Now designated 4079, this region has returned and was previously sunspot region 4055. It has already emitted an M-class solar flare, and we may expect greater activity as it becomes more Earth-centric over the next week.

NOAA predicts that the solar flux index will climb again in the coming week, perhaps rising to between 160 and 165. Geomagnetic disturbances are also due to rise, with the Kp index forecast to reach five on the 5th and 6th of May.

If this becomes a reality, expect lowered MUFs and poorer HF paths, especially over the poles as the Kp index rises.

And finally, this week traditionally marks the start of the Sporadic-E season so keep an eye on 10m and 12m for short- and medium-range openings to Europe.

And now the VHF and up propagation news from G3YLA and G4BAO

The current spell of high-pressure Tropo weather weakened a little as last week ended and we’ll see the return of unsettled conditions with showery rain, perhaps even the odd thunderstorm.

This is unlikely to lead to a total removal of high pressure and Tropo will still be worth looking for, especially over the western side of the UK. Some models place a new high just west of Britain during the coming week.

This means that the rain prospects are not great, although probably just enough for a hint of rain scatter in any isolated heavier showers.

The HF bands sounded a bit ‘watery’ at times last week, which is a classic sign of potential aurora to explore on the higher bands. Look out for aurora in the coming week if the Kp index climbs above five.

Meteor scatter is worth thinking about and, after last week’s Lyrids, we now have the Eta Aquariids shower peaking in the early hours of the 6th of May.

Remember that Sporadic-E ionisation is largely composed of long-lived meteor ions, so be on watch for Es openings. From now onwards through to mid-September, Sporadic-E will dominate the lower VHF bands, so check the clusters for signs of activity. Remember that Es starts on 10m and moves HF as an opening develops, even reaching 2m in the peak summer.

Unlike Tropo, Es events are often fleeting, so the best you can do is monitor conditions as the Es intensifies and be ready when it reaches the band you want. Don’t forget to check the daily Es blogs on www.propquest.co.uk which discuss the potential links between location of jet streams and Es formation.

EME path losses are increasing, but apogee is still a week away. Moon declination passed maximum last Thursday so Moon windows are shortening along with reducing peak elevation. 144MHz sky noise is low all week.

And that’s all from the propagation team this week.

GB2RS News

Sunday, the 27th of April 2025

The news headlines:

• RSGB delegates attend special IARU Region 1 Interim Meeting in Paris
• Join the RSGB in celebrating World Morse Day
• Be part of the RSGB’s team at the Youngsters on the Air summer camp

The RSGB is participating in the International Amateur Radio Union Region 1 Interim Meeting in Paris this weekend. The event is of particular historical significance as it coincides with the centenary of the founding of the IARU in 1925, as well as the 75th anniversary of the establishment of IARU Region 1 in 1950. The French host society, REF, is also marking its 100th anniversary. This year’s meeting in Paris reflects a broader scope than in previous years and, for the first time, includes ‘Youth Matters’ on the agenda. It also covers the usual focus areas of HF, VHF, UHF and Microwave, as well as Electromagnetic Compatibility. The RSGB has been a key contributor to the meeting, submitting papers that include future options for the 23cm band and the harmonisation and protection of HF bands. Three delegates from the RSGB are attending the meeting in person, including the newly appointed RSGB President Bob Beebe, GU4YOX. There will be eight other RSGB representatives attending remotely. The meeting serves as both a celebration of amateur radio’s rich heritage and a forward-looking forum to address the challenges and opportunities facing the global amateur radio community. You can view meeting documents at conf.iaru-r1.org In celebration of the centenary of the IARU the RSGB has created a web page to share information about its part in the celebrations. This includes a link to an RSGB archive video from the IARU meeting in Paris in 1950, as well as the RSGB’s July 1925 T & R Bulletin that contains an announcement detailing the formation of the IARU. Go to rsgb.org/iaru-centenary for further details.

Today, Sunday the 27th of April, is World Morse Day. The day honours the birthday of the inventor of Morse code, Samuel Morse, who was born on this day in 1791. To celebrate the occasion, the RSGB has released a video with a question in Morse code for you to answer. Once you have used your Morse skills to decipher the question, get involved by leaving your answer in the comments section under the post. You can view the video on the RSGB YouTube channel via youtube.com/theRSGB or search for @theRSGB on Facebook or X.

The deadline to apply to be the Team Leader for this year's Youngsters On The Air Summer Camp is Friday, the 2nd of May. This year's camp takes place between the 18th and 25th of August near Paris and is a chance of a lifetime for young RSGB members to represent their country and their national society. If you are an RSGB member, aged between 21 and 30, and are able to motivate a team of young people, then the RSGB would love to hear from you.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 24th of April 2025

We had yet another week of unsettled geomagnetic conditions. The Kp index peaked at 5.33 on the 21st of April as the solar wind speed hit just above 600 kilometres per second, and active geomagnetic conditions were observed.

This was caused by a massive coronal hole on the Sun’s surface, which measures nearly 700,000km in length. At the time of writing, part of it is still Earth-facing, but the Bz or interplanetary magnetic field is facing North, so its negative effects are not being felt.

The Kp index was down to 3.67 on the morning of Thursday, the 24th of April, but it wouldn’t take much for the Bz to swing southwards and for the Kp index to rise again.

Meanwhile, the solar flux index has risen from a recent low of 148 up to 168. This has meant MUFs over a 3,000km path have reached 25 MHz at times, but have usually been slightly lower. If the Kp index can stay low, there is a good chance of higher MUFs being attainable, but we have probably seen the best of 10m propagation until the autumn.

Much of the recent DX has been worked on slightly lower frequencies, such as VP2VI British Virgin Islands on 40 and 20m, C5R The Gambia on 20 and 12m, and HD8G Galapagos Islands on 20, 17, and 12m. There is still the chance of DX on 10m, but it may be fleeting.

Next week, NOAA predicts that the solar flux index will stay high, perhaps reaching 170 to 175. We may get a slight respite from unsettled geomagnetic conditions from the 26th to the 30th of April, when the Kp index is forecast to be around two to three. However, unsettled geomagnetic conditions are forecast for the beginning of next month, with Kp indices of five or six on the 1st and 2nd of May.

And now the VHF and up propagation news from G3YLA and G4BAO

Next week, high pressure should dominate, meaning a chance of Tropo for much of the time which will probably favour paths to the east, to Scandinavia or northern Europe.

Rain scatter won’t have featured much other than over northwest Britain in recent days, and meteor scatter is reducing back to random activity, which tends to be better in the early hours before dawn.

The solar conditions have continued to keep the Kp index up, and there was a fine auroral opening last week on the 16th of April, so for more aurora, it’s still worth checking for when Kp values nudge above five.

As the end of April moves into May, we can start to give serious thought to the coming Sporadic-E season. Hesitant beginnings often show up on 10m and 6m, and, as usual, the digital modes will be best for any weak events. CW and SSB are just possible in the stronger openings, especially on 10m.

The background rule is that there are usually two preferred activity periods, one in the morning and a second in late afternoon and early evening. However, at the start of the season, there can be a lot of spread in the timings.

EME path losses are at their lowest with perigee today, Sunday the 27th, and the Moon declination is positive and rising. Moon windows will lengthen along with peak elevation, and 144MHz sky noise starts the week low but increases to moderate as the week progresses. From late Sunday to early Monday, the Sun and Moon are close.

And that’s all from the propagation team this week.

The UK and Ireland DX CW Contest starts at 1200UTC on Saturday the 26th of April and ends at 1200UTC on Sunday the 27th of April. Using CW on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. UK and Ireland stations also send their district code.

The SP DX RTTY Contest starts at 1200UTC on Saturday the 26th of April and ends at 1200UTC on Sunday the 27th of April. Using RTTY on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. SP stations also send their province code.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 17th of April 2025

Last week was characterised by increased Kp index numbers and severe geomagnetic storms, peaking at G4. These drove down maximum usable frequencies and disrupted DX contacts, especially on the higher HF bands.

The solar wind speed increased from 380 kilometres per second to around 500 kilometres per second on the 15th and an increase in plasma density was noted as well. Subsequently, the Kp index peaked at 7.67 on Wednesday the 16th, causing visible aurora alerts in the UK.

This was caused by a pair of CMEs that left the Sun on Sunday the 13th of April. We had a total of 22 M-class solar flares over four days, so a CME event was inevitable.

Unsettled geomagnetic conditions are a feature on the declining side of a solar cycle, so we could unfortunately be in for many more.

According to Propquest, MUFs over a 3,000km path fell to below 18MHz for long periods on Wednesday the 16th, before climbing to around 21MHz at the end of the day.

Meanwhile, the solar flux index fell from a high of 170 on Friday the 11th of April to a low of 148 on Wednesday the 16th of April.

Next week, NOAA predicts that the SFI will start the week around 145 but could increase to 165 as the week progresses. Unsettled geomagnetic conditions are forecast for the 22nd to the 24th of April, with a predicted maximum Kp index of four.

As always, keep an eye on solarham.com for daily updates, but more importantly, get on the bands, which are a much more effective guide to HF propagation!

And now the VHF and up propagation news from G3YLA and G4BAO

The current period of unsettled weather looks likely to continue into the coming week. This does not mean rain every day, but periods of rain or showers with some intervening drier spells. These drier interludes are not really dominated by high pressure, just gaps between the wetter periods, so it's unlikely to produce much significant Tropo.

In terms of propagation, there may be some rain scatter, although it won’t be very reliable. However, the prospects for meteor scatter are more promising with the peak of the Lyrids due on Tuesday the 22nd of April. It is worth checking up on procedures for meteor scatter working if you’ve not done it before and you may find a new part of the hobby to add to your operating schedule.

The prospects for aurora continue to be raised by what seems like an almost daily supply of aurora alerts. Continue to monitor the Kp index for signs of elevated values, where Kp is above five, for radio activity. Early signs such as fluttery signals on the LF and HF bands may suggest it's worth looking on the VHF bands for auroral activity.

As we move towards the new season it is good to get into the habit of looking for Sporadic-E. The Propquest website www.propquest.co.uk shows several useful components for analysing the Es prospects. If you look at the position of the jet streams shown on the Es blog tab, these can produce favourable conditions geographically to give a hint of the right direction in which to listen. The opening season typically favours 10m or 6m.

EME path losses are now decreasing towards perigee on Sunday the 27th of April. Last Friday, the 18th of April, saw minimum Moon declination, so Moon windows will lengthen along with peak elevation. 144MHz sky noise starts this week very high but decreases to low as the week progresses.

And that’s all from the propagation team this week.

The RSGB is looking to recruit volunteers from the exam tutor community to help pre-screen documentation prior to public release as part of the process of improving the quality of documents issued by the Exam and Syllabus Review Group (ESRG). The Exam Tutors Review Panel is intended to be an informal group of approximately six tutors who are currently involved in providing training for amateur radio licence exams at any of the three current levels. Panel members will be asked to use their skills to help improve the quality of the syllabus, the questions in the published question bank and other published documentation. They will receive advance copies of documents that are due to be published, and they will be expected to return any comments within an agreed timescale, which typically will be two weeks. The ESRG is not obliged to accept the recommendations from panel members, but if they do not accept a recommended change, they will explain why. All documents and additional correspondence sent to panel members will be under an embargo until the final versions are released to the public. The Exam Tutors Review Panel is intended to run for an initial six months and will then be reviewed. If you are interested in becoming a member of this panel, please email Board Director Len Paget, GM0ONX via GM0ONX@rsgb.org.uk

On Thursday the 17th of April, the 70MHz UK Activity Contest runs from 1900 to 2130UTC. Using All modes on the 4m band, the exchange is signal report, serial number and locator.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 10th of April 2025

A fast solar wind caused some disruption last week, often sending the Kp index up to five, with many three-hour periods in excess of four.

The solar wind speed was in the 600-700 kilometres per second range, which caused a moderate, G2, geomagnetic storm and visible aurora at higher latitudes mid-week. Glancing CMEs that left the Sun on the 9th of April brought a small chance of enhanced geomagnetic activity at the end of the week.

Meanwhile, the solar flux index declined slightly from a high of 184 on the 5th of April to 167 on Thursday the 10th. There have been quite a few C-class solar flares, but only two M-class flares and no X-class events over the past seven days.

This geomagnetic activity has taken its toll on HF propagation, with lower critical frequencies at times and lower MUFs. This, coupled with the start of a change to summer ionospheric conditions, has meant that MUFs over a 3,000km path have often struggled to get past 19.7MHz at times.

We have probably seen the best of the long-range 10m propagation until the autumn. But we will have Sporadic-E and its associated short skip from next month to make up for it.

Next week NOAA predicts that the solar flux index will fall further, perhaps to between 135 and 140 by the 15th of April. Geomagnetic conditions are also likely to improve with a Kp index of two to three, forecast for the period after tomorrow, the 14th of April. We may expect more problematic geomagnetic conditions, with a predicted Kp index of four, from the 21st to the 24th of April.

And now the VHF and up propagation news from G3YLA and G4BAO

The long spell of fine settled weather and strong Tropo is leaving us for a while, starting this weekend, and the high pressure is giving way to slow-moving areas of low pressure with cloud and rain for the coming week.

Although it won’t rain all the time it will be considerably wetter than recent weeks, with some heavy spells of rain at times and good prospects for rain scatter on the GHz bands. It is possible that there could be some thunder in the heavier rain, so it’s now the season to be aware of lightning risk.

The meteor scatter prospects are staggering towards the 22nd of April Lyrids, which peak on Tuesday of the following week, so we’re still probably relying on random activity for most of this coming week, but with improving chances.

The solar conditions have been feeding low-level auroral activity and it remains a good time of the year when some effective auroral conditions can appear - so stay alert to the state of the Kp index, just in case.

The good news at this time of the year is that Sporadic-E will eventually make an appearance, usually on 10m or 6m, and is quite often first picked out on the digital modes. It will be into late April before we need to get too excited about this, but there is no harm in getting a set of beacons in mind for tracking an opening.

Remember the main characteristic of Es is that it starts on the lower frequencies like 10m, and works up through 6m to 4m and then finally 2m in a high-summer opening.

EME path losses are at their maximum at apogee this evening, the 13th, and Moon declination is negative and falling further. Moon windows will continue to shorten with peak elevation reaching only eight degrees at the end of next week. 144MHz sky noise starts the week low but will increase during the week to more than 2300 Kelvin on Friday.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 3rd of April 2025

We had a week of mixed solar conditions, but it ended with an SFI of 182 and a Kp of 3.67 on Thursday, the 3rd of April.

The geomagnetic field declined to quieter levels following a prolonged period of active, Kp4 conditions earlier on Wednesday due to solar wind enhancements. This impacted propagation, with the critical frequency struggling to get much above 7 MHz on Wednesday.

Compare this with the following day, when the critical frequency hit 10.4MHz by 0830 UTC. Nevertheless, there was DX to be worked on Wednesday with FT8 allowing signals from Australia, Japan, Indonesia, China, and Surinam to get into the UK on 21MHz.

The solar proton flux was also high on Tuesday, the 1st of April, affecting signals passing through the polar regions, but this had declined by Thursday and was heading back to normal levels. This was due to a large CME observed off the east limb of the Sun on Frida,y the 28th of March. If it had been Earth-directed, we may have seen a massive aurora.

Next week, NOAA predicts that the solar flux index will stay in the 175-185 region. A Kp of six was forecast for yesterday, Saturday the 5th of April, followed by a further period of unsettled geomagnetic conditions due to an enhanced solar wind.

If this is the case, we may not get more settled conditions until the 14th to the 16th of April.

Nevertheless, this remains a good time for North-South HF paths, such as the UK to South Africa, and UK to South America.

And now the VHF and up propagation news from G3YLA and G4BAO

The old forecasting maxim that the ‘longer a high lasts, the longer it will last’ is built upon the presence of blocked upper air weather patterns. When the jet stream gets so distorted into a high-amplitude north/south wave, its lateral movement, from west to east, becomes very slow.

On the upper air charts, this takes the shape of the Greek letter omega, and this is the current set-up. It means that the weather associated with it also lasts a long time.

In this case, it’s the high pressure and its spell of fine weather that is likely to last for the whole of the coming week. The position of the high will change, though, starting over the North Sea and ending over the UK and the nearby Atlantic. This means that Tropo will be the mode of choice for the coming period, which includes the 70cm UK Activity Contest on Tuesday and the 6m UK Activity Contest on Thursday.

Rain scatter is unlikely during this extended period of dry weather.

The meteor scatter options are still mainly driven by random meteors for the coming period into next week, but the next important shower, the Lyrids, peaks on the 22nd of April. The auroral alerts continue to come through, raising interest. As usual, the clue will be fluttery-sounding signals on the bands, particularly noticeable on CW, but they can also be pronounced on speech transmissions. Monitor the Kp index for values above Kp5.

There have been a few trans-equatorial openings to Southern Africa on 50MHz digital modes for the fortunate few who live in the extreme south and southwest of the UK, but it did extend up to Cambridgeshire and Suffolk briefly on some days last week.

The long drought of Sporadic-E will soon be over, but we’re still in the realms of very isolated events for 10m and 6m, which will be short-lasting. The jet stream, which can be a good clue as to potential locations, suggests looking to Scandinavia, the Baltic and northern Europe.

EME path losses are falling again, but Moon declination has been at its highest this weekend, so we have long Moon windows. 144MHz sky noise is low throughout the coming week.

And that’s all from the propagation team this week.

The news headlines:

• RSGB AGM – your chance to ask the Board a question
• The RSGB has published new forms for exam question queries
• The April Tonight@8 webinar – using a glue stick in a homemade 40m receiver

Do you have a question about the RSGB’s strategy? Perhaps you have a query about recent licence changes? Or maybe you’d like to understand more about membership growth? Whatever the topic, the Society is asking you to get in touch. RSGB Board members will be answering your questions during the RSGB 2025 AGM on Saturday, the 12th of April. You can submit your question in three ways; live via Zoom, send a written question in advance, or during the live chat on the day. If you’d like to ask a question about the formal part of the AGM, you’ll need to do this via Zoom or by submitting a written question in advance. Don’t miss out on this opportunity to discuss what matters to you. Your participation in the AGM is important, and the Society looks forward to hearing from you. Find out more about how to be involved and the deadlines for submitting questions by going to rsgb.org/agm

As part of its modernisation of the exam systems, the RSGB has introduced online forms for reporting possible errors found in exam questions. These forms replace the current procedure of writing to the Exam Department. RSGB Examinations Standards Chair Tony Kent, G8PBH, explained that there are two forms. The first can only be submitted by exam candidates and is to formally challenge questions in actual exams, where the outcome of a challenge may affect a candidate’s result. The second form can be submitted by anyone and is for informal queries of published exam questions, for example, in mock exams. A separate form is needed for each question that you challenge. Please check carefully that you are using the correct form, otherwise, it may delay the process. Your query will be considered by the RSGB Examinations and Syllabus Review Group, who will let you know the outcome. For more information and to find the forms, go to rsgb.org/exam-challenges

The next webinar in the RSGB’s Tonight@8 series will be with Nick Wood, M0NTV, on Monday, the 7th of April. Nick will show you how to use a regular glue stick housing in a rather novel way to form the basis of a variable tuning inductor in a homemade 40m receiver. After a brief description of a Direct Conversion Receiver and a short technical explanation of how it works, Nick will dive into four separate modules. At the end of the webinar, he will string it all together, and you’ll be able to see some video footage of how it sounds and what it can do. Visit rsgb.org/webinars to find out more. Join the presentation live on the RSGB YouTube channel or special BATC channel and ask questions via the live chat.

The RSGB is delighted to announce that Chris Aitken, MM0WIC, who is the current RSGB Youth Champion for Schools, is taking on the new position of RSGB Youth Chair.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 27th of March 2025

Last week’s space weather was dominated by a large coronal hole on the Sun. This was probably one of the largest we have seen for many years.

Moderate, G2, geomagnetic storming was observed following the arrival of a solar wind stream from the hole, with the wind speed exceeding 600 km/s on Wednesday, the 26th. This pushed the Kp index to 6.33, depressing the MUF slightly.

Luckily, the daytime MUF over a 3,000km path mostly stayed above 28 MHz, but it was slow to rise on Thursday, the 27th, when it took until 0900 UTC to reach 28 MHz. At the time of writing, the solar wind speed was more than 800km/s, so we can expect more disruption until at least Saturday, the 29th.

Meanwhile, the solar flux index declined to 152 by Thursday, the 27th, with only four small sunspot regions visible.

CDXC members have been discussing working New Zealand in the morning at the ZL sunset, often on low power. Listen and look for ZL4OL and ZL2CC, usually on FT8, but if conditions allow CW and SSB. 20m or 40m seems to be the favourite, and the VarAC data mode seems popular in ZL as well.

Next week, NOAA predicts the solar flux index will climb again, perhaps to 180 by the 4th of April. However, unsettled geomagnetic conditions are forecast again, beginning on the 3rd. We may expect the Kp index to reach six, which could be the start of at least ten days of disruption.

And now the VHF and up propagation news from G3YLA and G4BAO

The overall picture for the weather patterns in the coming week is that of high pressure, which means that Tropo should be available as a good mode for VHF bands.

There can be quite strong temperature inversions in the region of large well-developed areas of high pressure. The best performance will usually be around the edges of the high where the height of the inversion and ducting layer is typically between 0.5km and 2km above the ground, and can cover large distances for excellent DX prospects.

Occasionally, a shallow ducting layer can form near the ground overnight but often disperses by mid-morning. If you are in a good inversion region, try SSB or CW on the VHF/UHF bands, as paths of up to 1,500km can often be achieved from a good ‘tropo lift’.

The reverse side of the high-pressure systems is that we will have low pressure nearby, mainly to the north and west of the UK. Any potential for rain scatter will mainly be over northwestern Britain, although an active front that was moving south on Friday, the 28th of March, was a good candidate for chance rain scatter on the GHz bands.

The prospects for meteor scatter are still largely dependent upon random meteors, which are usually best in the hours before dawn. Current solar activity will continue to trigger auroral alerts in the coming week.

Now onto Sporadic-E, and last week we had a few out-of-season isolated foEs ‘blips’ to between 5- 7 MHz, which was enough to produce propagation on 10m and 6m, albeit very fleetingly.

There have already been some equinox-related 6m trans-equatorial propagation or TEP workable from the Southern part of the country, so keep an eye open late morning for Africa and late afternoon for South America.

EME path losses have continued to improve until perigee this morning, the 30th of March. Moon declination is still falling, and reached a minimum last Friday, the 28th. Moon windows will increase throughout the coming week. 144MHz sky noise is low, apart from Saturday the 29th when the Sun was close to the Moon in the sky, rising to moderate next Thursday before dropping back to low for the weekend.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 20th of March 2025

Last week was pretty unremarkable from an HF perspective. After the disturbed geomagnetic conditions on the 12th to the 14th when the Kp index rose to five, conditions were a little more settled.

The solar flux index hit 204 on the 17th of March but then declined back to the 180s.

Having said that things were settled, the Kp index did exceed four for three periods on the 19th, peaking at 4.67. This had the effect of reducing the MUF over a 3,000km path to 21-24MHz.

We also had two M-class solar flares on the 17th and the 19th, with the latter causing a coronal mass ejection that may give Earth a glancing blow around the 22nd of March.

As spring progresses, we may find the F2-layer MUF dropping as we move to summer ionospheric conditions, perhaps to be replaced by enhanced sporadic-E conditions on 10 metres instead.

Next week, NOAA predicts that the solar flux index may drop further, perhaps hitting 150 on the 28th. Unsettled geomagnetic conditions are forecast for the 25th to the 28th, with a maximum Kp index of five.

As we said last week, this is now a peak period for auroral activity, given the angle that the Earth makes with the Sun. The 'Russell-McPherron' effect is down to the alignment of the Sun and Earth around the spring and autumn equinox and means that you are twice as likely to experience the aurora in spring and autumn than in winter and summer.

And now the VHF and up propagation news from G3YLA and G4BAO

The recent fine weather has provided some useful Tropo. This has been mainly towards the east and into the near continent, which seemed like nice timing for the 1.3GHz UK Activity Contest last Tuesday evening.

Despite this, many participants reported conditions as poor. The high is now moving away and by the time you hear this, it will be a predominantly low-pressure weather sequence from now on. This means limited Tropo in the coming week, and rain scatter comes to the fore as a mode of choice if you have a GHz band set up.

The solar conditions continue to provide a trickle charge of auroral alerts, but not enough for any significant operating advantage. As usual the message is to keep on top of things by monitoring the Kp index for values over 5.

Meteor scatter remains largely in the gift of random meteors, so it's an early start to catch the pre-dawn peak of random meteors if you are so persuaded.

Lastly, a mention of Sporadic-E which is still in its close season. We have a while to wait until later next month when we could expect the occasional stirrings on 10m.

EME path losses continue to improve until the Moon’s perigee (its closest point to Earth) on the morning of the 30th of March. Moon declination has been falling, reaching a minimum yesterday, the 22nd.

So again, we have short Moon windows and reduced peak Moon elevation. 144MHz sky noise started high on Friday the 21st of March but will drop back to low by the middle of next week.

And that’s all from the propagation team this week.

On Tuesday the 18th of March, the 1.3GHz UK Activity Contest runs from 2000 to 2230UTC. Using all modes on the 23cm band, the exchange is signal report, serial number and locator.

Also on Tuesday the 18th of March, the IRTS 80m Evening Counties Contest runs from 2000 to 2100UTC. Using CW and SSB on the 80m band, the exchange is signal report, serial number and county code.

On Thursday the 20th of March, the 70MHz UK Activity Contest runs from 2000 to 2230UTC. Using all modes on the 4m band, the exchange is signal report, serial number and locator.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 13th of March 2025

We’ve had another week of disturbed geomagnetic conditions with the Kp index at four or five for long periods. On the evening of the 12th of March, Kp was five and, at the time of writing, has stayed there for a total of five three-hour periods.

This has taken its toll on the ionosphere with MUFs over a 3,000km path down to less than 24.7MHz during daylight.

Meanwhile, the solar flux index rose to 160 on Thursday the 13th after hitting a low of 147 on the 7th.

The best HF propagation was last weekend, the 8th and 9th of March, just in time for the Commonwealth Contest. This saw stations around the world romping into the UK, including signals from Australia, New Zealand, the Falkland Islands, Barbados, and many others.

As contacts were limited to Commonwealth countries, it meant the UK had little QRM to contend with and it was fairly easy to fill the log book on 40m to 10m.

Australia was still coming in at 59 after dark, and even British Columbia on the west coast of Canada could be worked with simple wire antennas and low power.

This may have been caused by a pre-auroral enhancement, as the Kp index rose late on the first day of the contest.

Next week, NOAA predicts the solar flux index may rise to 195 by the 21st. It also suggests that we may be back into calmer geomagnetic conditions with a maximum Kp index of two. This will be a welcome change and, if it happens, will no doubt result in better HF conditions.

And remember, March is a good month for north-south contacts, such as the UK to South Africa and the UK to South America.

But with the equinox just around the corner, auroras are twice as common due to the Russell-McPherron effect.

Just as when two bar magnets attract one another when they are oriented oppositely, so opposite Bz components attract. During the autumn and spring equinox, this orientation enables a 'connection' to the Sun, thereby allowing the solar wind to stream in.

And now the VHF and up propagation news from G3YLA and G4BAO

The recent change to colder weather brought showers and potential rain scatter to the second half of last week. But this weekend we have lost the showers and gained a large region of high pressure to bring a hint of Tropo.

It's not perfect, since in cold air highs like this, conditions are usually less than ideal, so don’t expect too much from this particular area of high pressure.

The high will last until midweek before it slips away into eastern Europe and, on its parting, may allow some moisture below the inversion and will improve the Tropo prospects briefly. The second half of the coming week will be dominated by low pressure and back to rain-scatter as an option on the GHz bands.

The solar conditions have continued to provide a few weak auroral alerts and it's worth continuing a watching brief on the Kp index for hints of activity; anything greater than a Kp of five is worth our interest.

Listen out for watery-sounding signals on the LF bands and then check out the 10m and 6m bands for auroral signals.

The next important meteor shower is the April Lyrids, but there’s always the chance of random meteor scatter activity, particularly in the pre-dawn hours.

It’s still a little early to mention Sporadic-E, but it’s always worth looking at the lower frequencies first, which means 10m and 6m. Check the graphs on Propquest for signs of spikes in the foEs, which is the critical frequency of the Es-layer.

EME path losses continue to rise until apogee on Monday evening. Moon declination is still falling, reaching a minimum on Saturday the 22nd. So again, we have short Moon windows and reduced peak Moon elevation. 144MHz sky noise is moderate and rising to high by Friday the 21st.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 6th of March 2025

We started last week with geomagnetic disturbances that saw the Kp index rise to a maximum of 5.67 on the 28th of February and then hover around the 4.5 mark for the next couple of days.

As predicted, the rest of the week went quite well, with the Kp index in the range of one to four.

The solar flux index fell from a maximum of 210 on the 23rd of February to a low of 140 on the 2nd of March. It then climbed back to 160 on the 4th. Over the past week, we have had no X-class and only one M-class solar flare which was on the 5th.

As we head into next week, it looks like all the sunspots in the Sun’s northern hemisphere have now departed. Nevertheless, the southern hemisphere is still supplying lots of spots so don’t panic just yet!

HF conditions have been quite good. VK6IF and VK6IA in Western Australia were booming in on 28MHz USB on the morning of Thursday the 6th, as was VK9CU on the Cocos-Keeling Islands.

Nigel, VP8TXF and Ian, VP8CIW have been operating from the Falkland Islands ahead of this weekend’s Commonwealth Contest and have been worked from the UK on 20m-10m. They are there until the 10th, so get in quick.

Other DX to be worked this week includes VU4AX Andaman Islands, 6Y7EI Jamaica, PJ7AA Sint Maarten Island, 4S7KKG Sri Lanka, TY5C Benin, 6W7/ON4AVT Warang Senegal, RI1ANE Antarctica and H44MS Solomon Islands.

Next week, NOAA predicts that the solar flux index will start off around 150 and may then climb to 185 by the 16th. A large coronal hole became Earth-facing on the 6th, which may result in unsettled geomagnetic conditions this weekend, the 8th and the 9th.

It looks like we can expect unsettled geomagnetic conditions around the 10th to the 16th, with a maximum predicted Kp index of five.

And now the VHF and up propagation news from G3YLA and G4BAO

The weather divides into two segments; the first, from the middle of last week through to the middle of next week, is rather changeable with low pressure nearby bringing rain or showers and potential for rain scatter on the GHz bands.

Eventually, the unsettled weather ends with a cold northerly on Tuesday the 11th and this leads to a new high building from Wednesday into the weekend of the 15th and 16th March.

This is good news for Tropo and could possibly be of benefit to those in the UK 70cm Activity Contest on Tuesday the 11th in the western UK, but more generally for the FT8 70cm Activity Contest on Wednesday and the 50MHz UK Activity Contest on Thursday evening.

We are still between major meteor showers and therefore must rely upon random activity for now. The next shower of note is the Lyrids on the 21st and the 22nd of April, so we have a while to go yet.

The solar activity has continued to produce a regular supply of auroral alerts and fluttery signals on the LF bands, but with a lot of clouds in northwestern areas and southern parts just marginally out of reach for any naked-eye auroras. A few digital camera pictures did surface on the web.

Keep an eye open just in case though. Remember Kp equalling five or greater is where we need to be.

Lastly, the Sporadic-E prospects are still relatively low with only the odd minor blip up to around a Sporadic-E critical frequency of 5 to 7MHz, often around the middle of the day. This contrasts with the morning and evening windows in the main season. It is enough to promote interest in the 10 or 6m bands, but almost certainly a fleeting moment.

EME path losses rise all this coming week and moon declination falls with associated shortening Moon windows and reducing peak Moon elevation. The best results will therefore be early in the week. 144MHz sky noise is moderate this weekend, falling to low in the week commencing the 10th.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 27th of February 2025

We had another week of mixed geomagnetic conditions. The Kp index rose to a high of five with visible aurora over the UK at times.

Two large coronal holes are now both facing Earth. A solar wind stream flowing from these zones is expected to flow past Earth, possibly on Friday the 28th of February or Saturday the 1st of March. Active geomagnetic conditions with a Kp index of four are currently forecast for this weekend.

There has also been more solar flare activity over the past seven days with an X2-class flare on the 23rd and ten M-class flares. The X-class flare occurred at 19:27UTC so had little effect in Europe as the Sun had set. Luckily, an associated coronal mass ejection was not Earth-directed. Another fast-moving CME on the 24th was also not Earth-directed.

As we enter March it looks as though the Sun is still very active. The solar flux index stood at 180 on Thursday the 27th, after hitting 210 on the 23rd. Maximum usable frequencies over 3,000km are still reaching 34-35MHz around midday, while night-time MUFs are generally around 10-11MHz, with occasional openings on 20 metres.

This week Bob, VP8LP on the Falkland Islands has been active on 10 metres SSB and has been worked from the UK.

As we enter March this is a good time for North-South paths on HF, such as UK to South Africa and UK to South America. The spring equinox is also a good time for auroral conditions.

NOAA predicts the Sun will start next week with an SFI of 190, perhaps falling to 170-180 as the week progresses. We hesitate to say this, but geomagnetic conditions are predicted to be good once we get past the disturbances on the 28th and the 1st, but only time will tell!

And now the VHF and up propagation news from G3YLA and G4BAO

There is likely to be a welcome return of high pressure for much of the period from this weekend until the middle of the coming week on the 5th of March.

Models show a return of unsettled Atlantic weather, meaning lows, fronts, showers and rain scatter for the GHz bands. Until then, it will be typical high-pressure Tropo conditions with an extensive temperature inversion aloft caused by the descending warming air in the high-pressure region.

This should provide ducting conditions over a large part of the country. As often, the far north of the UK will probably just miss out and retain too much breeze for the inversion to be effective.

The lull in meteor shower activity continues, so once again your best chances will be in the morning hours around, or just before, dawn.

The Sun has kept aurora seekers busy and shows how frequently it can just tip into the right disturbed conditions at this stage of the solar cycle. As we said earlier, there have been reports of visible aurora in the past week.

The signs for this are the Kp index rising to five or greater and flutter on LF band signals or trans-polar paths on the HF bands.

The new Sporadic-E season is almost upon us, but we are not there yet. Check the graphs on Propquest for signs of enhanced foEs values and check the HF bands first; 10m is particularly good for strong European Es signals.

EME conditions will be predictable as usual, with Moon declination rising all week and path losses at their minimum at perigee late on Saturday the 1st of March. 144MHz sky noise is low from this coming weekend, rising to moderate by Friday the 7th.

And that’s all from the propagation team this week.

Sunday the 23rd of February 2025

The news headlines:

• The RSGB announces the unopposed candidates in its elections
• The RSGB releases 2025 Band Plans
• A year in numbers 2024 – some great things to celebrate!

Nominations in the RSGB elections have closed. For some roles, a single nomination was received, and the candidate is therefore elected unopposed. They will take up their role at the end of the RSGB AGM in April. These unopposed candidates include the roles of President and also Regional Representatives in Regions 1, 4, 7, 8, 10, 11 and 12. In Region 9, no valid nomination was received. For more information about each of these unopposed candidates, see the March issue of RadCom or the RSGB website at rsgb.org/election

The RSGB Band Plans for 2025 were published in the March 2025 issue of RadCom. They are also available on the RSGB website via rsgb.org/bandplans. This year’s plans incorporate further VHF and UHF changes in response to the increased demand that has been prompted by the new Ofcom amateur licence. There are also a few changes from the 2023 IARU Region-1 General Conference. All amateurs are reminded to consult the Band Plans before operating.

Despite continuing challenges nationally and across the world during 2024, the amateur radio community stayed strong and the RSGB supported it. The RSGB General Manager Steve Thomas, M1ACB wrote his annual feature called ‘A year in numbers’ for the March RadCom and shared some great things to celebrate, in which RSGB HQ staff often led the way. You can also see the highlights in a brief video on the RSGB YouTube channel. The April RadCom will show in detail the work of the committees and other specialist volunteers.

Girlguiding groups will be celebrating World Thinking Day on the Air this weekend so listen out for them and encourage the young operators. To highlight the opportunities for young people to get involved in amateur radio activities, this week the RSGB has published two new videos that celebrate the fantastic ISS contact and STEM day held in the autumn and attended by HRH The Duchess of Edinburgh. You can watch both the videos on the RSGB YouTube channel.

Between January and March 2024 Bob Bower, GM4DLG took on a one-man antipodean adventure. The DXpedition is currently being serialised in RadCom, and on Monday the 3rd of March, he will be delivering a Tonight@8 presentation to complement these features. The trip was eight weeks long and covered 27 activations from 11 sites on six islands. Bob operated on 20, 40 and 80m with 100W SSB into vertical arrays of his design, with his holy grail being a valid 80m greyline QSO with Great Britain. Visit rsgb.org/webinars to find out more. Join the presentation live on the RSGB YouTube channel or special BATC channel and ask questions via the live chat.

Don’t forget to submit your entry to the RSGB Construction Competition by Saturday the 1st of March. You’ll need to email a short description of your entry and up to four photographs. It is also recommended to send a link to a video that demonstrates your entry working. More details on submitting your application can be found via rsgb.org/construction-competition The results of the competition will be announced during the 2025 RSGB Annual General Meeting in April.

Exercise Blue Ham will take place on the 29th and 30th of March on the 60m band. Stations will be active between 9 am and 6 pm. Blue Ham exercises provide a platform to further develop Cadet radio operator skills and confidence by engaging with the amateur radio community via the MOD 5MHz shared band. Cadet radio operators, under supervision, will exchange radio messages with amateur radio operators in the UK and Europe. The Cadets hope to speak to many radio amateurs on the air. For more information visit alphacharlie.org.uk/exercise-blue-ham

The 26th European Hamradio School Stations Day will take place on Monday the 5th of May from 0700 to 1700UTC. This is an activity day, not a contest, so the focus is on personal radio contacts and QSO partners should take time for a short exchange. The organisers look forward to seeing many schools, universities and training centres on the air again. To find out more, go to tinyurl.com/european-schools

Please send details of all your news and events to radcom@rsgb.org.uk The deadline for submissions is 10 am on Thursdays before the Sunday broadcast each week.

Now the Special Event news

On 26 February 2025, the 90th anniversary of the Daventry Experiment will be commemorated, marking a pivotal moment in the development of British radar technology. The Daventry Experiment had a lasting impact on both military strategy and civilian applications. To honour this milestone, several special event stations will be active. The Bawdsey Radar Museum will be hosting GB2BRS, with BRS representing Bawdsey Radar Station, whilst Coventry ARS from near Daventry will operate GB9ORE, with RE representing Radar Experiment. Chelmsford ARS from Great Baddow in Essex will activate GB9OCH with CH representing Chain Home since Chelmsford is where one of the original Chain Home radar masts still stands.

Special callsign S5701DX is running during February in memory of Slavko, S57DX who became a Silent Key last February. The station has been heard recently using CW and SSB on the HF bands. For more information visit QRZ.com

From the 1st to the 28th of March George, MM0JNL will once again be activating special event station GB0GTS. This year the station is active in support of the Great Tommy Sleepout. This national challenge aims to raise funds and awareness for all former UK service personnel who are living homeless. More details are available at QRZ.com and rbli.co.uk

Now the DX news

Datta, VU2DSI is operating from Lonar Lake in India until tomorrow, the 24th of February. This unique location was formed by the impact of a meteor around 550,000 years ago. The station will be active on the 40, 20, 15 and 10m bands using SSB. More information can be found at QRZ.com

Now the contest news

The CQ 160m DX Contest started at 2200UTC on Friday the 21st and ends at 2200UTC today, Sunday the 23rd of February. Using SSB on the 160m band, the exchange is signal report and CQ zone. USA stations also send their state and Canadian stations send their province.

The REF Contest started at 0600UTC on Saturday the 22nd and ends at 1800UTC today, Sunday the 23rd of February. Using SSB on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number.

The UBA DX CW contest started at 1000UTC on Saturday the 22nd of February and ends at 1300UTC today, Sunday the 23rd of February. Using CW on the 80 10m bands, where contests are permitted, the exchange is signal report and serial number. Belgian stations will also give their section code.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 20th of February 2025

It seems we were a little over-ambitious in suggesting that last week would be better for HF propagation. It looked like we would avoid coronal mass ejections and see the Kp index fall to lower levels.

Unfortunately, the Sun had other ideas and a fast-moving solar stream, often moving faster than 500 km/s, had a south-pointing Bz, which coupled more easily with Earth and sent the Kp index up to four or more.

So even by Wednesday the 19th, the Kp index was hitting five.

However it seems that the geomagnetic disturbance merely lowered the MUF from around 40-45MHz to 31-32MHz, so it barely affected HF propagation.

At the time of writing, there had only been one M-class solar flare in the past five days, but more than 50 minor C-class events. There were no Earth-directed CMEs.

Nevertheless, there was DX to be had with the standout stations being the V73WW DXpedition to Majuro Atoll on the Marshall Islands, TI1RRC Costa Rica, and 5N9DTG in Nigeria. Upcoming DX next week includes OX3LX (Greenland), Dave G4BUO as 5W0UO (Samoa), TO3Z (Guadeloupe), 4S7SPG (Sri Lanka) and FS/VA3QSL (St Martin).

Next week, NOAA predicts that the week commencing the 23rd of February could see the solar flux index starting at 170, but then rising to 195-200 as the week progresses. Geomagnetic conditions are predicted to start quietly, with a Kp index of two, but then become unsettled by the 27th to the 29th, with a maximum predicted Kp index of five.

If this scenario does pan out then we may expect the best HF conditions to occur at the beginning of next week, from the 23rd to the 26th.

As always, keep an eye on solarham.com for day-to-day solar news, and perhaps monitor PSKreporter, the Reverse Beacon Network and DX Clusters for digital, CW and SSB HF propagation updates.

And now the VHF and up propagation news from G3YLA and G4BAO

The current spell of unsettled weather seems likely to continue through to the end of next week. There will also be significant windy weather at times. It is therefore not a particularly good period for Tropo, or big antennas for that matter.

This leaves us with rain scatter on the GHz bands and some of these scattering regions will be large areas affecting the whole of the country as weather fronts pass by, rather than more isolated and harder-to-follow showers which often provide our rain scatter.

Meteor scatter is still within its quieter period with no major showers and better chances coming from random meteor activity, which tends to peak in the hours before dawn.

Recent solar activity has provided some weak auroral conditions on many days. As usual, check for high values of the Kp index as a good indicator, or even listen for a watery tone on the LF bands. Ultimately you will need to see the Kp index going to at least five to make it worth checking for auroral signals on VHF.

We are still in the dormant period for Sporadic-E propagation, which is a shame given the powerful jet streams likely during this stormy weather. These would produce good Es prospects in the main summer season, but weaker Es at low VHF are still a possibility despite being out of season.

Moon declination is at minimum today, Sunday the 23rd of February, and path losses are decreasing as the Moon moves closer to Earth as it heads to perigee on Saturday the 1st of March. 144MHz sky noise goes high this weekend, beginning Saturday the 22nd.

And that’s all from the propagation team this week.

The news headlines:

• The RSGB has announced its Scout, Cadet and Girlguiding Youth Champion
• Listen out for stations operating for World Thinking Day on the Air
• New resources and ideas have been added to the RSGB British Science Week web pages

The RSGB is delighted to announce that Samuel McCutchion, M7UEL will be the RSGB's Scout, Cadet and Girlguiding Youth Champion. Sam brings a wealth of hands-on experience to the role having been part of the Scouts from a young age in Beavers and then working his way up to Network. He then progressed to become an Assistant Section Leader. This knowledge will help the RSGB Youth Team to engage and offer amateur radio support to not only the Scouts but also the Cadets and Girlguiding. If you’d like to congratulate Sam on his role, or if you have any ideas you think would be useful to share, email him via youthchampion.scouts@rsgb.org.uk

Lots of amateur radio stations are on the air this weekend and next weekend for World Thinking Day on the Air. Listen out for them and encourage the young Girlguiding members. You can find details of some of the active stations via rsgb.org/thinking-day but, if your station isn’t listed, please share details on the RSGB social media channels. The event aims to encourage Girlguiding members to make friendships with those in other units, using amateur radio as the means of communication.

Have you visited the RSGB’s British Science Week web pages yet? Two new worksheets have recently been added to inspire you to get involved and showcase amateur radio to new audiences. The activities were designed by the RSGB Outreach Team to fit in with this year’s British Science Week theme of ‘Change and adapt’. If you’d like to deliver these activities to schools or youth groups, the Society has sample lesson plans, risk assessments and a guide to contacting your local school available on its website. Remember that British Science Week isn’t just for younger audiences, it is open to all. If you’re looking for ideas to get your friends and family involved or a local community group, go to rsgb.org/bsw and visit the British Science Week resources page. There is a wealth of ideas available, from looking at the history of radio communications to building a sustainable system using only solar panels. If you have an activity planned for British Science Week, let the RSGB know by emailing the RSGB British Science Week Coordinator, Ian Neal, M0KEO via bsw@rsgb.org.uk Details of events taking place will be shared on the Society’s website.

The deadline for the RSGB Construction Competition is Saturday the 1st of March, which means you have less than two weeks left to submit your entry. The judges will be considering entries in six categories: beginners, construction excellence, innovation, software, antennas and outreach. To find out how to submit your application go to rsgb.org/construction-competition The results of the competition will be announced during the 2025 RSGB Annual General Meeting on the 12th of April.

If you are passionate about amateur radio and have some spare time to support fellow radio amateurs, why not become an RSGB District Representative? There are currently 12 vacancies across the United Kingdom, including in Belfast, Cambridgeshire and Lancashire. To find out if there is a vacancy in your region go to rsgb.org/volunteers and then get in touch with the Regional Representative of the district with the vacancy.

Amateur radio operators are reminded to take care when operating on the WRC-15 secondary amateur allocation at 5MHz. The UK still has no access to the full WRC-15 allocation. Despite requests, this seems unlikely to change in the foreseeable future. Whilst the UK is fortunate to have more generous licence conditions, these mustn't be put at risk by irresponsible operating in violation of the licence conditions, particularly in the 5358 to 5362kHz gap where there is no UK allocation. The RSGB website has detailed advice for operators, both for SSB and digital modes, on its rsgb.org/5mhz web page. Please take care not to transmit outside of the UK segments even if you hear other amateurs transmitting. Remember that signals heard may be coming from amateurs in other countries with different allocations.

The RSGB ARDF Committee is pleased to announce the return of the British ARDF Championships in 2025. The Championships will be held as a three-day festival in early April 2025. Entries open on the 1st of March and will remain open right up until the event itself. Further information and updates can be found at tinyurl.com/ARDF25

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 13th of February 2025

Two large coronal holes on the Sun’s surface have been spraying solar material towards Earth, pushing the Kp index to a high of 4.67.

The solar wind speed has been consistently higher than 500 kilometres per second and, with a south-pointing interplanetary magnetic field, the plasma has flooded into Earth’s magnetic field. There have been a few aurora warnings, but these have only been minor.

As a result, the ionosphere has not been too badly affected and daytime maximum usable frequencies over a 3,000km path have generally remained above 28MHz, with the odd dip towards 24MHz.

Coronal mass ejections have not made an appearance and there were only three M-class flares between the 9th and 13th of February.

Meanwhile, the solar flux index fell to the 150s and 160s last week.

Recent HF DX has included the V73WW DXpedition on the Marshall Islands, which has been worked from the UK, including on the 40, 30 and 20m bands using CW. The TX7N DXpedition to Marquesas Island in French Polynesia has just finished. It wasn’t an easy path, but it was worked from the UK on all bands from 30 to 12m using FT8, CW and SSB.

Next week, NOAA predicts that the solar flux index could rise a little, to be in the 180 to 190 range. Once Earth is free from the effects of the current coronal hole stream, we may expect the Kp index to retreat, perhaps to a maximum of 2.

So, DX next week could be quite reasonable but, as always, keep an eye on solarham.com for daily updates.

And now the VHF and up propagation news from G3YLA and G4BAO

The lingering high pressure just to the east of the UK is holding weather fronts over western Britain for the time being with any tropo benefits confined to eastern areas and being marginal at best.

During the coming week, changes will be slow but gradually a more determined push on the Atlantic fronts may bring them over most areas, except the extreme southeast of the country.

This will make rain scatter more accessible although the models suggest that the fronts are likely to become weaker. So, they will not be especially useful by the time they reach the southeast. Sporadic-E is in its quiet season now, as are the meteor scatter prospects, with no major showers in attendance until the spring Lyrids in late April.

Perhaps this quieter time is a chance to do some operating housekeeping. For example, you could update a list of nearby repeaters and beacons to help you track developing openings. Or maybe you could consider trying a new mode or band. Perhaps you could learn to use digital modes for meteor scatter. Maybe consider joining the increasing numbers trying CW on the 2m band.

Moon declination went negative again on Saturday the 15th and path losses are rising as the Moon moves away to apogee, its furthest point from Earth, on Tuesday the 18th. 144MHz sky noise is low for most of the coming week but goes high for the weekend of Saturday the 22nd.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Wednesday the 5th of February 2025

Last week went pretty much as predicted. The solar wind from a large coronal hole impacted the Earth on Saturday the 1st of February, pushing the Kp index to four. The hole was so large that the geomagnetic disturbance lasted until the early evening on Sunday.

Once the solar wind speed had dropped, things got back to normal and the Kp index has been in the range of 1 to 2 ever since.

The event appeared to have had little effect on HF propagation, with maximum usable frequencies over a 3000km path remaining above 28MHz during the daylight hours. So it looks like we dodged a bullet.

At the time of writing, we have had 21 M-class flares in three days.

A solar flare measuring M8.8 was detected around active region 3981, peaking at 0358UTC on the 3rd of February. This was the strongest flare yet from this region in terms of peak X-Ray flux. However, the flare itself was impulsive and was not the source of a coronal mass ejection.

Over the next week, NOAA predicts that the solar flux index could fall slightly to be in the 180 to 200 range. Make the most of the good propagation as we may be entering a period of unsettled geomagnetic conditions again from the 10th to the 17th of February. NOAA predicts that the Kp index could rise to a maximum of 5 on the 13th but is likely to be in the range of 3 to 5 over the seven days.

Part of this may be down to another coronal hole which became Earth-facing on the 6th of February. There is also a good chance that we could get an X-class eruptive flare from active regions 3981 or 3978, which could result in a coronal mass ejection.

We recommend you keep an eye on solarham.com for daily updates.

And now the VHF and up propagation news from G3YLA and G4BAO

High pressure during the second half of last week brought some useful tropo conditions. As this week, ending today the 9th comes to a close there are some wintry showers along North Sea coasts, which may produce some snow and rain scatter. However, this may be weakened by the nearby high pressure.

By the end of this week, ending today the 9th, there will be a change of weather pattern as the high, having now migrated to Scandinavia, leaves room for Atlantic weather systems to encroach from the west during the coming week. This could bring rain scatter possibilities to the western side of the country. These should be more useful than the eastern coast ones at the end of last week since the rain will probably be heavier and the fronts slow-moving.

This time of year is something of a desert for Sporadic-E propagation although look out for lesser events as a result of jet streams. You can track these on the Propquest website.

Keep a look out for auroras during the week beginning tomorrow, the 10th. The likelihood of M-class flares is around 85%, while the chance of X-class flares is approximately 20%. So keep an eye on the Kp index for any potential solar events that could cause auroras.

Next week, there are no major meteor showers. The next significant meteor shower, the Lyrids, will become active in April. Keep checking the pre-dawn period for random meteors.

Moon declination reached a maximum yesterday, Saturday the 8th. Path losses are still low but will increase throughout the coming week. This means that this weekend, ending today the 9th, should produce good activity for EME, especially on the GHz bands with long Moon windows and high peak Moon elevation.

144MHz sky noise is moderate this weekend, ending today the 9th, but falls to low for the rest of the coming week.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 30th of January 2025

Last week was pretty unremarkable as far as the Sun goes, but it looks like that is about to change.

The seven days preceding Thursday the 30th were characterised by reasonably settled geomagnetic conditions, with a maximum Kp index of 3.67 and a solar flux index that fell from 205 on the 24th, to the 170s by the 30th. During this period there had been only four M-class solar flares and no X-class events.

Over the next few days, things could change. Two large coronal holes near the Sun’s equator threaten to upset the quiet conditions. As the solar material flows out it could cause the Kp index to rise, perhaps to 4, with reduced maximum usual frequencies and noisy conditions. But this will depend upon its associated Bz or interplanetary magnetic field.

If it is south-pointing it will couple more easily with the Earth’s magnetic field, allowing plasma to flow in, and the Kp index will rise. However, if it is north-pointing we may see very little effect at all.

So, keep an eye on Solarham.com for real-time updates and look for increased solar wind speed as the main indicator of the approaching solar material.

If the Bz does point south we may expect unsettled conditions and possible aurora today, the 2nd.

Meanwhile, three sunspot groups are rotating into an Earth-facing position in the Northern Hemisphere on the Eastern side of the Sun. We have already seen an M-class flare from one of them.

These could boost the solar flux index but could also be a source of solar flares and coronal mass ejections over the coming week.

Strangely, NOAA does not seem to think they will, as its predicted solar flux index over the next seven days is in the 150 to 160s range. It does agree with our prediction of unsettled geomagnetic conditions, although with a projected Kp index of 5 today, the 2nd, falling to 4 over the next three days.

We will just have to wait and see.

Meanwhile, maximum useable frequencies over a 3,000km path are still exceeding 28MHz from around 0830 to 1600 UTC. As the month moves on, we can expect the amount of daylight to increase, so this period may be extended.

Make the most of 160 and 80m as the optimum time for these bands has now passed.

And now the VHF and up propagation news from G3YLA and G4BAO

The tail end of the previous week saw a few weak weather features as lows and a front brushed past. However, from this first weekend of February, there will be a trend to higher pressure, which will offer up some tropo opportunities at times during the coming week.

There is a chance of the occasional decaying front drifting down the country but, for most of the next week, it’ll be a tropo story, if anything.

50MHz has been quiet again as we await the return of maybe the last Spring equinox-style propagation of this cycle around mid-March.

Meteor scatter is once again mostly down to random activity although there is one minor shower, the Capricornids-Sagittariids, which peaked yesterday, Saturday the 1st of February.

Rain scatter may be somewhat rarer due to the mainly high-pressure pattern.

Some auroral propagation is not without hope in view of the large coronal hole, which crossed the Sun last week. Keep a lookout for high Kp values, and keep an ear open for watery signals on the LF bands as a good sign of potential activity on the higher bands.

Moon declination goes positive again today, the 2nd. With perigee having passed late yesterday, the 1st, this means that the upcoming week will be good for EME. This is especially true on the GHz bands if you have a clear view of the horizon. 144MHz sky noise is low, rising to moderate next weekend.

One final note: there have been some access problems with the data feeds for the Propquest website. Hopefully, these are temporary and have fixed themselves by the time you hear this broadcast. The other data plots such as jet stream charts should continue to update so there is plenty to look at on the other pages.

And that’s all from the propagation team this week.

GB2RS News

Sunday the 17th of November

The news headlines:

• The RSGB has launched a new practical events section on its website
• The RSGB Awards Manager has added categories to the IARU Region 1 Award
• There is still time to host the Youngsters on the Air Month call sign

The RSGB is keen to promote practical events for radio amateurs as a way of developing their skills and retaining their interest in amateur radio. The Society has also demonstrated that buildathons are a great way of engaging new audiences, giving people a taste of amateur radio in a fun and supportive environment. As part of its strategy, the RSGB held two workshops at the 2024 Convention to introduce individuals to radio-related usage of Micro Controller Units, or MCUs as they are often known. The Society also holds annual build-a-radio events at Bletchley Park for youngsters, with the kits provided by the Radio Communications Foundation. To support radio amateurs to try practical skills themselves or to put on their events, the RSGB has published a new section on its website that is dedicated to practical events. You’ll find a guide to running a buildathon, detailed information from the MCU workshop as well as a short video to inspire you! Feedback from the RSGB’s events has been wholly positive with requests for similar activities around the country. Could your club host an event and perhaps even boost its numbers at the same time? Find out more at rsgb.org/practical-events

The RSGB Awards Manager has announced that, with the support of the Board, he has added new categories of achievement to the IARU Region 1 Award. These include WARC bands only, 10MHz only, 18MHz only and 24MHz only. The standard IARU Region 1 Award check spreadsheet should continue to be used for these categories. However, award chasers are advised to keep separate versions for each band or set of bands. There are no mode or power restrictions and there is no distinction between fixed and portable stations; you just have to be operating within the same country for all QSOs used in the application. There aren’t any limitations on the start dates for the awards other than the dates for particular countries as identified in the check sheet. This reflects, for example, when a country became a member of the IARU. The RSGB would like to thank the award chasers who contributed to the discussions about adding new categories.

With just two weeks to go until Youngsters on the Air Month, operating slots for GB24YOTA are fast filling up. The special call sign will be active throughout December and is a fantastic opportunity to get youngsters active on the amateur bands. Whether you are part of a school, university, youth group, club or individual, the RSGB would love you to be involved. The Society would be delighted to see the callsign hosted every day during December and see as many youngsters on the air as possible. Be part of this goal by visiting QRZ.com and searching GB24YOTA to check availability. Operating slots aren’t fixed and can be adjusted to suit your timings, so don’t delay. Email Jamie, M0SDV via yota.month@rsgb.org.uk now. Visit rsgb.org/yota-month to find out more.

The RSGB National Radio Centre at Bletchley Park will be closed on Christmas Eve, Christmas Day, Boxing Day and New Year’s Day. There will also be reduced hours on New Year’s Eve when the centre will be closing at 2 pm. Following the seasonal closures, the NRC will also be closed for essential maintenance works on the 2nd of January 2025. Outside of these times, volunteers look forward to welcoming visitors as usual. Remember that RSGB Members can download a free entry voucher for Bletchley Park from the RSGB website via rsgb.org/bpvoucher.

The CQ World Wide DX CW Contest starts at 0000UTC on Saturday the 23rd of November and ends at 2359UTC on Sunday the 24th of November. Using CW on the 160 to 10m bands, where contests are permitted, the exchange is signal report and CQ Zone. The UK is in Zone 14.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 14th of November.

The solar flux index took a downturn this week, ending up at 150. The visible solar disk is looking rather bare compared with a couple of weeks ago.

This is the lowest SFI value since the 2nd of May 2024, but it is only a matter of time before we see another sunspot appear as we make our way through solar maximum.

The good news is that we have been pretty devoid of solar flares and coronal mass ejections, with only a few M-class flares occurring. Any CMEs were not Earth-directed and so the Kp index stayed low.

As a result, the bands are still playing ball. A quick look on 10 metres at 10.00UTC on Thursday the 14th showed the 4X6TU (Israel), OH2B (Finland) and LU4AA (Argentina) International Beacon Project beacons were romping in on 28.200MHz.

Going down to 15 metres it was even better, with ZL6B (New Zealand), VK6RBP (Australia) and JA2IGY (Japan) all audible on 21.150MHz.

Also, the proton flux from the Sun remains low, which bodes well for polar paths.

Next week the Space Weather Prediction Centre forecasts that the solar flux index will rise again, no doubt as new or returning sunspots appear, perhaps putting us into the low 200s.

From a geomagnetic perspective, unsettled conditions are forecast for Wednesday, the 20th of November when the Kp index could rise to four.

Looking further ahead, fingers crossed for the 23rd and 24th weekend when the CQ Worldwide CW contest takes place!

And now the VHF and up propagation news from G3YLA and G4BAO.

It was more of the same on 50MHz last week, with what may be a mix of Es and F2-layer propagation producing morning openings in the afternoon to the Gulf States, Southeast Asia, and the Americas.

On the higher bands, with the high pressure just hanging on in its colder guise, next week looks distinctly on the wintry side for some areas.

The high pressure has, along with its predecessor, given us at least two weeks of Tropo conditions on the VHF bands. The expected change-over to low pressure takes place on Sunday and drives a colder northerly weather pattern down across the UK, even to southern areas. This means that the majority of next week is a good time to look for rain scatter.

Regarding meteor scatter, the peak of the Leonids occurs today, the 17th of November, with rates of 15-20 per hour.

Also, occasional peaks of the Kp index above four should tempt us to beam north for chance aurora openings. As usual, check the VHF beacons and clusters for signs of activity during the afternoon and evenings when the auroral oval is displaced southwards nearer to our part of the world.

It's a good week for EME operators, the Moon reaches peak declination on Monday morning, but path losses are rising as we have passed perigee on Thursday the 14th. 144MHz sky noise is moderate, reaching 500 Kelvin on Sunday night.

And that’s all from the propagation team this week.

Sunday the 10th of November

The news headlines:

• The RSGB launches its 2025 Construction Competition
• The RSGB Contest Club needs volunteers for the second World Wide Award event
• Watch more great content from the RSGB 2024 Convention

The RSGB has launched its Construction Competition for 2025. Entries to this annual competition will again be judged online to allow RSGB members from the UK and across the world to participate and demonstrate their creativity. In line with the Society’s strategic priority of growth, there will be a new Outreach category this year in which members are encouraged to submit a project that can be reproduced in a school or public environment. The other five categories are beginners, construction excellence, innovation, software and antennas.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 7th of November.

We had another week of high solar flux and good conditions on HF.

Solar activity remained at high levels thanks to an impulsive X2.3 solar flare around active region 3883 at 13:40 UTC on the 6th of November, but the event was not responsible for a coronal mass ejection (CME).

The Kp index remained below 4.5 all week, with a solar flux index in the range of 240-260. That was more than enough to keep the ionosphere very active.

A recent report on spaceweather.com suggested that the solar cycle may have peaked in the Sun’s southern hemisphere but may still have a way to go in its northern hemisphere.

It's usual for there to be two peaks in a solar cycle as the two hemispheres are seldom synchronised. We will have to wait and see, but it could mean another three to six months of high SFI numbers as the northern hemisphere catches up.

A solar filament located in the southwest quadrant erupted on the 7th of November. A coronal mass ejection, or CME as it is also known, occurred but appeared to be off the Sun-Earth line, so no major impacts are expected.

A sunspot group turning into view from off the southeastern limb has been assigned active region 3889 and is producing M-class solar flares. The probability of further M-class flares stands at 80%. Meanwhile, the risk of an X-class flare currently stands at 35%.

A coronal hole is currently Earth-facing and could cause some disruption sometime around Saturday 9th.

The solar proton flux has decreased to normal levels, so polar paths should now be unaffected.

Next week, NOAA predicts that the SFI could decline into the range of 165-185. Geomagnetic disturbances are forecast for the 11th and 12th, and again on the 15th, with the Kp index predicted to reach four.

Meanwhile, we do urge you to get on 10 metres, which is currently experiencing some fine DX openings. This month and next will probably give the best chance of good 10-metre propagation for a while.

And now the VHF and up propagation news from G3YLA and G4BAO

Another week has just passed with daily F2-layer propagation on 50MHz providing morning openings to Southeast Asia, and the Americas in the afternoon. Expect more in the coming week.

The current spell of high pressure has had a good run with some excellent Tropo conditions, with the best DX along the side of the high pressure.

This weekend will see the high finally giving way as weak Atlantic fronts move in from the west. This will soon be replaced by a new high building in the colder air behind the weekend fronts. It may look like Tropo should come back, but this high may be less productive.

The major change of weather pattern comes before mid-week, when it may turn more unsettled as low pressure moves closer to eastern areas from the North Sea. This general move towards more unsettled conditions will continue through the end of the week.

In terms of propagation, good Tropo will be replaced by some patchy rain scatter opportunities for the GHz bands from about the middle of next week.

Staying with scatter modes, meteor scatter looks promising with the Taurids peaking on Tuesday the 12th and the Leonids due to peak on the following weekend on Sunday the 17th.

The solar conditions continue to offer chance occurrences of aurora due to solar flares or CMEs so, as usual, keep a watch on the Kp index going above Kp=4.

An occasional reminder of the possibility of out-of-season Es for the digital modes is timely. Recently the critical frequency of the Es layer has reached 7MHz on the Dourbes ionosonde plotted on www.propquest.co.uk and in theory, this would be good enough for a 6m band path.

For EME operators, Moon declination is negative but rising, going positive again on Tuesday the 12th. Path losses are falling as we approach perigee next Thursday the 14th. 144MHz sky noise is moderate to low this coming week.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday 31 October 2024.

Last weekend’s CQWW SSB contest showed just how good autumnal HF conditions can be. Many contestants worked more than 100 countries or DX entities on each and every HF band.

With a solar flux index of 238 on Saturday and 246 on Sunday, plus low Kp indices all weekend, it was about as good as it could get. There were two three-hour periods where the Kp index hit four and 4.33, but it was otherwise in the ones and twos.

An X-class solar flare occurred on Saturday the 26th at around 07:15 hrs UTC, but this had little effect and the MUF over a 3,000km path was back above 28MHz quite quickly.

The rest of the week saw numerous M-class and C-class solar flares occur and a Kp index that did get up to four at times, but once again the MUF remained above 28MHz during daylight for most of the time.

Interestingly, there have been times when the critical frequency over the UK has hit 14MHz, making 20m almost a local chat band via Near Vertical Incidence Sky Wave or NVIS communications! These openings may be short-lived so make the most of them should they occur.

Nighttime critical frequencies have generally been around 4.5-6MHz, meaning a MUF over a 3,000km path over 14MHz in the first half of the night and around 10-12MHz in the second half.

The solar proton flux has been above the 10MeV warning threshold but is now falling as of Thursday 31st. This may improve signals that pass through the polar regions, such as the UK to the far west of Canada and Alaska, and the UK to Japan.

Next week NOAA predicts that the SFI will start at around 240, but perhaps fall to around 195-200 as the week progresses. ESA predicts that the solar wind speed could increase around November 4th and could cause disruption.

As always, we are at the mercy of solar flares and CMEs, which could disrupt HF propagation, so we recommend keeping an eye on solarham.com for daily updates.

And now the VHF and up propagation news from G3YLA and G4BAO

The Autumn Equinox period continued to bring F2-layer propagation to 50MHz with almost daily morning openings to VK and JA and afternoon openings to the Americas for some.

Stations in the far South and West of the island were favoured. Side scatter in the Indian Ocean brought the JAs on a 90-degree beam heading, an effect noted at previous sunspot maxima.

The autumn is typically a time for quiet settled weather, a season of mist, and this is where we are going for the period through to the end of next week. It's worth a couple of reminders of how it all works since, although it's likely to be pretty much the same ‘big picture’ of dominant high pressure, there will be subtle differences.

Firstly, there are two types of high pressure; one that builds in warm air and the other in cold air. The warm air version is the current offering, and this means quite cloudy conditions at times with moist air below the temperature inversion and very dry air above the inversion.

Second, the quality of the ducting is determined by the change of the refractive index across the inversion and a large part of the refractive index change comes from a contrast of moisture, so signs of cloud and/or fog moisture are good omens for a lift. We may swap over to a cold air high later next week, which could lessen the Tropo quality.

Meteor scatter prospects are on hold pending the Leonids meteor shower, which peaks mid-November. A dominant high pressure means that rain scatter is not likely to be a big player for the GHz bands next week.

There is a possible heads-up for aurora since the solar conditions still offer chances for the Kp index to rise – anything over Kp=4 is worth a longer look – and don’t forget that ‘watery’ signals on the lower HF bands such as 40m and 80m are also a good sign.

For EME operators, Moon declination reaches a minimum (that is, maximum negative declination) next Tuesday when the Moon only reaches nine degrees peak elevation and is only above the horizon for six hours between 1200 and 1800hrs. Path losses, on the other hand, are falling all week.

144MHz sky noise is moderate to high, peaking at more than 3,000 Kelvin on Tuesday the 5th before dropping back to moderate levels.

And that’s all from the propagation team this week.

The news headlines:

• The RSGB releases a snapshot video of the exciting Girlguiding ISS contact
• You can listen to the Chair of the RSGB’s Propagation Studies Committee on the latest episode of the ICQ podcast
• The RSGB has begun releasing presentations from its 2024 Convention

On the 5th of October, in her first official engagement as Girlguiding Patron, Her Royal Highness The Duchess of Edinburgh joined 100 excited Brownies, Guides and Rangers in making a live amateur radio contact with the International Space Station. The event was organised by The Radio Society of Great Britain and Amateur Radio on the International Space Station, or ARISS as it is usually known, in collaboration with the UK Space Agency, Girlguiding Surrey West and Brooklands Museum’s Innovation Academy programme. The aim was to promote the engagement and involvement of girls and young women in science, technology, engineering and mathematics. Everyone had a fantastic day and after the contact, the girls enjoyed a variety of STEM activities including making Snail Morse keys, playing Morse battleships, learning about the CubeSat Simulator and making stomp rockets. The RSGB has created a short video snapshot of the day which you can see on its YouTube channel at youtube.com/theRSGB – take a look!

The latest episode of the ICQ Podcast is available to listen to online and features RSGB Propagation Studies Committee Chair, Steve Nichols, G0KYA. During episode 441 Martin Butler, M1MRB talks to Steve about propagation and how the sunspot cycle has taken off to impact conditions positively. They also discuss Ham Radio Science Citizen Investigation, which is also known as HamSCI, a collective that enables university researchers to collaborate with radio amateurs in scientific investigations. To access the interview, select episode 441 at icqpodcast.com and listen from 1 hour and 35 minutes.

If you are thinking of taking an amateur radio exam before Christmas, there are two important dates you need to be aware of. The last date you can take an exam at a club, whether online or on paper, is Friday the 13th of December. If you want to take an exam online at home, the last date you can do that is Friday the 20th of December. The RSGB Exams Team will, where possible, post-out exam results before HQ shuts over Christmas and New Year. Exams will resume on Monday the 6th of January 2025 and the booking system will be available over the festive season so you can book exams for January onwards. You can book online on the RSGB website at rsgb.org/exampay

On Friday the 18th of October the RSGB, Mill Hill School and a team of radio amateurs in New Zealand took part in a special celebration to mark the centenary of the first successful two-way trans-global communication between radio amateurs in the UK and New Zealand. The original contact between Frank Bell, 4AA in New Zealand and Cecil Goyder, 2SZ in Mill Hill School in North London was re-enacted at the school on a wavelength as close as possible to the original. Members of Goyder’s family watched the re-enactment and chatted to pupils. As part of wider celebrations for the day, the school put on activities including a build-a-radio workshop. Students at the school showed significant interest in amateur radio, with several students signing up to be part of a new radio club that will be set up by the school’s physics teacher. The overall event was led by RSGB Life Vice-President Don Beattie, G3BJ who said that he was delighted by the success of the event and that it had allowed pupils to learn how ground-breaking that first radio contact was with New Zealand. Call sign G2SZ was operational for four days surrounding the centenary, during which operators achieved approximately 1,250 contacts. To find out more about this unique celebration go to www.gb2nz.com and search for ‘GB2NZ re-enactment’ on the RSGB website.

The Memorial Day QSO Party is an activity providing participants with an opportunity to honour amateur radio operators who are now Silent Key. The event is being sponsored and managed by the First Class CW Operators’ Club and is open to all licensed amateurs. The event begins at 0900UTC on the 1st of November 2024 and ends at 0859UTC on the 2nd of November. More information is available at g4foc.org or by emailing mdqp@g4foc.org or michelecarlone@yahoo.it

Ofcom has notified stakeholders that the next release of its licensing service will be delayed due to issues that have arisen during software development. According to the Ofcom website, the delays have impacted Phases 2 and 3 of the planned changes to the amateur radio licensing framework. Phase 2 includes changes to new Intermediate callsigns, special event station rules and restrictions on the number of callsigns an individual may hold. Revised plans are expected to be published soon. You can read the update on the Ofcom website via tinyurl.com/OFCOMOCT24

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 24th of October 2024

Last week’s solar conditions couldn’t have been much better. We had a week of high solar flux indices, relatively calm geomagnetic conditions and, other than an X-class solar flare, not much else to report.

The solar flare originated from active region 3869 and reached a strong X3.3 in the early hours of October 24th. This event was associated with a coronal mass ejection, or CME, based on solar dimming following the event, but because the flare location was located off the east limb, it was directed mostly away from Earth.

Once again, all the sunspots are in the southern hemisphere, but activity appears to be growing. This could spell trouble over the next week.

This weekend, the 26th and 27th, the CQ Worldwide SSB contest is taking place and conditions should be excellent, with a combination of high solar flux and autumnal HF conditions.

Maximum usable frequencies, or MUFs, are generally higher than 28MHz from dawn until dusk. Nighttime MUFs over 3,000km are still just above 14MHz, although you might get better results by dropping down to 10MHz if the 20m band doesn’t work for you.

Next week, NOAA predicts that the solar flux index may rise again, perhaps hitting 185 as we enter November. However, this current bunch of sunspots, which are rotating to be Earth-directed next week, appear more active and we could see more solar flares and CMEs, which could throw a spanner in the works.

A solar flare could impact the ionosphere by increasing D-layer absorption, for up to an hour or so, and possibly launch a coronal mass ejection.

If a CME hits the Earth, expect the MUF to plummet, at least for a day or two until the ionosphere recovers.

And now the VHF and up propagation news from G3YLA and G4BAO

The Autumn Equinox period brought some amazing ionospheric propagation to 50MHz on Thursday last week with stations in the UK working morning paths to VK, JA, DS and XV among others.

Typically for 50MHz DX, the skip zones were sharp and moved rapidly. Stations even a few kilometres apart experienced very different signals and paths. Those with a low noise floor had a huge advantage as signals were generally weak in the UK and only good for FT8. However, some reports of a VK station at +5 bucked this trend.

Next week will offer some reasonable Tropo conditions, although not without some occasional interruptions from weak frontal systems, especially in the far southwest and the far northwest of Britain. It’s not clear if these represent good rain scatter options, but they are more likely to temporarily curtail any Tropo for a while.

The solar conditions continue to feed the occasional aurora alert our way, so it’s always good to monitor the Kp index for signs of it increasing above 4. It won’t always go on to produce a radio aurora, but it's worth keeping an eye on things.

The meteor scatter prospects continue to be elevated by the decline of the Orionids, which peaked on Tuesday the 22nd, and the Taurids, which are a very low-rate shower, but technically cover a broad period into December. The Leonids are the next major shower, but that doesn’t peak until mid-November.

Lastly, looking at the out-of-season Sporadic-E prospects, there are always days with minor enhancements of the critical frequency of the Sporadic-E layer, as shown on the propquest.co.uk graphs. Certainly, there are stronger jet streams available in the autumn and winter, but other elements of Sporadic-E are not so favourable. It’s usually a very marginal outcome at best, but good enough for the 10 or 6m bands and mostly for digital modes such as FT8.

It could well be that trans-equatorial propagation, or TEP, is a more fruitful venture.

For EME operators, Moon declination is positive, but falling, going negative on Tuesday the 29th. Path losses are rising, reaching a maximum at apogee on the morning of Wednesday the 30th. 144MHz sky noise is low until Friday the 1st of November when the Sun and Moon are close in the sky.

And that’s all from the propagation team this week.

GB2RS News

Sunday the 20th of October

The news headlines:

• The RSGB welcomes your feedback on its 2024 Convention
• Today is the last chance to get involved with JOTA 2024
• The RSGB is looking for Youth Champions

The RSGB’s 2024 Convention took place last weekend and brought together hundreds in person, as well as many more from across the globe who watched via the livestream. The Society is already receiving an overwhelming amount of positive feedback, but if you did attend the Convention and haven’t yet completed the feedback form, please go to rsgb.org/feedback and share your thoughts. If you watched the livestream the Society would also love to hear your feedback. Please visit rsgb.org/livestream-feedback and let the team know what you think of the online event. The feedback forms will be closed at the end of October. The live streams for both days will remain available for everyone to watch, so if you’d like to catch up on the selection of presentations that were aired, go to the RSGB website and search for ‘Convention 2024 Livestream’. As well as talks from the weekend, you’ll find exclusive special interviews and pre-recorded videos.

Today, the 20th, is the last day of Jamboree on the Air, also known as JOTA. The event promotes friendship and global citizenship and is a brilliant celebration of amateur radio among the Scout Association. The Society has compiled a list of Scouting groups that are involved with the annual event and has shared it on its website. The list is available by going to rsgb.org/jota and choosing the ‘JOTA Stations on the Air’ link on the right hand side of the page. The RSGB would love to see your photos of Scouts getting involved with JOTA, so tag @theRSGB and also use #JOTAJOTI to be involved in the conversation on social media. If you’re not involved with a JOTA station do listen out and encourage the young operators on the air. There will be a report in RadCom so please send details and photos from your event to radcom@rsgb.org.uk by the 15th of November.

Following the recent appointment of two Youth Champions for schools and universities, the RSGB is keen to expand the team. The Society is looking for a Youth Champion for scouts, guides and cadets, and another to lead activities and create resources to support young people once they have gained their Foundation licence, motivating them to try new things within amateur radio. The four Youth Champions will work closely as a team, as well as with the RSGB Board Liaison, Ben Lloyd, GW4BML and the RSGB Outreach Team. Together, the Youth Champions will also create a youth team and run a net or sked to involve all youngsters. Do you have what it takes to engage with young people and support them on their amateur radio journey? Another part of each Youth Champion’s role is to give input and support for current activities, such as promoting and participating in Youngsters on the Air Month each December. If you are proactive, experienced at managing your own time efficiently, a good leader who can build relationships and mentor young people, and you are passionate about growing the number of young people involved in amateur radio, then one of these roles could be for you! Take a look at the youth activities on the RSGB website at rsgb.org/youth and see some of the great things that are happening already. If you’re interested in being part of the team, contact Youth Board Liaison Ben Lloyd, GW4BML via gw4bml@rsgb.org.uk

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 17th of October 2024

The past week has been characterised by a low geomagnetic Kp index and excellent conditions on HF, including the 10m band. With a solar flux index between 168 and 195, and a Kp index that never rose above 4, conditions have been better than the previous week, which suffered from the bad effects of solar flares and coronal mass ejections.

This came as NASA, NOAA and the International Solar Cycle Prediction Panel announced that the Sun has reached its solar maximum period, which should continue for the next year.

The announcement was not unexpected, and the exact period of maximum activity won’t be known for some time. But it was a wake-up call for radio amateurs to get on the bands and make the most of the conditions!

NOAA anticipates additional solar and geomagnetic storms during the current solar maximum period and during the declining phase of the solar cycle.

The solar flux index fell from its 200-plus highs to be in the 160 to 195 range last week. But this was still more than enough to keep the ionosphere running. Maximum usable frequencies over a 3,000km path have been consistently over 28MHz during daylight, falling to around 11MHz overnight.

Next week, the Space Weather Prediction Centre thinks the solar flux index will rise into the 200s again, but we may also get some geomagnetic disturbances, namely on the 22nd and 23rd when the Kp index might rise to around 4.

Meanwhile, October can be one of the best months for HF propagation with good 10m band openings to Australasia in the morning and North and South America in the afternoon.

And now the VHF and up propagation news from G3YLA and G4BAO

The current unsettled spell of weather seems likely to continue into next week and is not atypical at this time of year. We should expect a more changeable pattern around the autumn as the main polar front jet stream migrates south across the UK into its winter state over the Mediterranean.

That said, there may well be some brief interludes when the extended region of high pressure across Europe influences conditions over the British Isles, more specifically the southeastern corner.

This is shown by some models around midweek for potential Tropo from southeastern England into the continent or across the North Sea to northern Europe and southern Scandinavia.

The obvious mode to result from this unsettled weather will be rain scatter and it is probable that the GHz bands will enjoy this period of weather.

Meteor scatter in October has a few showers to maintain interest. The Orionids and the Taurids are both active during the coming week. In fact, the Orionids, associated with the comet Halley, peak on Monday and Tuesday.

Just a final note about Sporadic-E, which is ‘out of season’. Remember that there are no ‘zero Sporadic-E months’ and recent indications have tended to show the response of raised critical frequencies of the Sporadic-E layer occurring around the middle of the day on the propquest.co.uk NVIS graphs.

You may also see peaks earlier in the day around dawn, which is the peak time for meteor input. Beware, it is easy to get hooked on out-of-season Sporadic-E hunting!

For EME operators, Moon declination is positive and rising. Path losses are rising again after the perigee on Thursday the 17th. So, we have increasing peak Moon elevations and longer Moon windows until Tuesday the 22nd. 144MHz sky noise is low to moderate for the rest of the week.

And that’s all from the propagation team this week.

GB2RS News

Sunday the 13th of October

The news headlines:

• The RSGB 2024 Convention is taking place this weekend
• Two new volunteer Youth Champions have been appointed by the RSGB
• Celebrations are underway to mark the first trans-global two-way radio communication

The RSGB Convention has been in full swing this weekend. If you haven’t been able to attend, the RSGB has provided a packed live stream on each day and those live streams are available for anyone to view. Full of presentations, interviews and videos to inspire you, this is another way to enjoy your Convention, in your way. Either go directly to the RSGB YouTube channel or head over to rsgb.org/livestream to see the programme of presentations and the links to the livestreams.

The RSGB is delighted to announce the appointment of two new volunteer Youth Champion roles. Chris Aitken, MM0WIC will be the RSGB’s School Youth Champion and Rhys Williams, M0WGY/AJ6XD will be the University Youth Champion. Chris is a Computing Science teacher at Wick High School, Caithness. Since 2023, Chris has been running the Wick High School Radio Club, GM0WHS, providing students with a wide range of experiences in amateur radio. He has four students who have passed their Foundation licence exam and are now taking on leadership roles within the club and assisting the latest cohort in their studies. He is also a member of the RSGB Outreach Team. You can contact Chris via youthchampion.school@rsgb.org.uk Rhys represented the RSGB at the Youngsters on the Air Camp in Prague this year. He sent back daily reports on his activities which you can still see on the website under the summer camps tab at rsgb.org/yota He is starting a PhD in Aerospace Engineering at the University of Oxford and is keen to help the RSGB support the growth of amateur radio in universities across the UK. You can contact Rhys via youthchampion.uni@rsgb.org.uk Ben Lloyd, GW4BML is the Board Liaison for youth activities. He said that he welcomes Chris and Rhys to their new youth volunteer roles and looks forward to working closely with them in the future to attract and grow RSGB youth membership. He explained that the three of them have already had some positive conversations and shared some good ideas, which they will be putting into place over the coming months.

This week marks the centenary of the world’s very first trans-global two-way radio communication. On the 18th of October 1924 Frank Bell, 4AA, from New Zealand, and Cecil Goyder, 2SZ, from North London, changed how we communicate forever by making contact on amateur bands. To commemorate this historic contact, special callsigns will be active, and awards and QSL cards will be available for those who make contact with these special stations. GB2NZ and ZM100DX have already been active since the start of the month. Starting tomorrow, until the 20th of October, calls reflecting Goyder’s callsign, G2SZ, and Bell’s, ZL4AA, will be active. This will include activity here in the UK from Mill Hill School in North London which is the original location from which Goyder made his contact. On Friday the 18th of October, radio amateurs will also be recreating and re-enacting the first contact between Goyder and Bell. It is hoped that the QSO will be made on a wavelength close to that used in 1924. To find out more about this unique celebration go to gb2nz.com

YOTA Month is just around the corner, and the RSGB is looking for volunteers to host the GB24YOTA callsign throughout the month of December. As in previous years, schools, clubs, guide and scout groups and also individuals are invited to host young radio amateurs whilst they operate with the callsign. Each day during the month has been split into a number of operating slots that you can book. In recent years, this system has allowed many more youngsters to get on the radio throughout the month. You can see the operating calendar by visiting QRZ.com and searching for GB24YOTA. Operators should be below the age of 26. Those who do not hold a Full amateur radio licence should be supervised by an appropriate Full licensee whilst operating. The RSGB is pleased that previous activators have already reached out to book their operating slots but there are still many more up for grabs! To book an operating slot or for more information about YOTA Month, please email Jamie, M0SDV at yota.month@rsgb.org.uk

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Wednesday the 9th of October 2024

What a difference a week makes when it comes to HF propagation!

This last week has been characterised by solar flares, coronal mass ejections, or CMEs for short, and an elevated Kp index. Put together, this has resulted in dire conditions on HF, reminiscent of a solar minimum.

A visible aurora was seen from the UK once again after the Kp index hit 7.33 on the 8th of October.

Numerous CMEs have hit the Earth and the solar proton flux has risen, resulting in a moderate S2 radiation storm as particles blasted away from the flare site.

This means poor trans-polar paths until the solar wind abates and the storm settles.

Maximum usable frequencies have been badly affected and struggled to get much past 14MHz over a 3,000km path on the 8th of October. Geomagnetic storms were also forecast for Thursday the 10th and Friday the 11th.

That’s a shame as, before the CMEs hit, HF had been humming with a lot of DX on the 28MHz band and many five-watt beacons romping in from the USA.

Next week, NOAA predicts that the solar flux index may drop back into the 170s, but it’s anyone’s guess as to how geomagnetic conditions will pan out.

We have had three X-class solar flares over the past week and on Wednesday the 9th the probability of another X-class solar flare was estimated at 30% and an M-class event at 75%. So, it may be a case of ‘batten down the hatches’ on HF until the storm conditions pass.

This is not uncommon at this point in the solar cycle and unsettled conditions are likely to continue as we move along the downward portion towards the solar minimum.

And now the VHF and up propagation news from G3YLA and G4BAO

The current spell of unsettled weather is probably going to flip into high-pressure mode a couple of times during the coming week. The first of these will be today, the 13th, and through the first half of next week.

However, by Wednesday the next change back to low pressure should be with us, closely followed by another attempt to build high pressure later in the week.

This offers something for everyone with prospects for rain scatter on the GHz bands and the possibility of Tropo.

The prospects for meteor scatter are also good with October offering several useful meteor showers.

While 50 and 70MHz are the best for the mode, look at 144.360MHz in MSK144 digimode. Or, if it’s a shower peak, 144.200MHz, the SSB meteor scatter calling channel, to see what’s around.

The solar conditions continue to behave like a solar maximum and, with several recent powerful flares and CMEs to stir things up, we should continue to check the bands for signs of aurora.

The recent RSGB CW 80m Autumn Series Contest on Monday the 7th of October was about as auroral as it gets with a strong flutter on signals and a challenging hour and a half for participants – so not just an effect for VHF.

The RSGB 1.3GHz UK Activity Contest coming up next week on Tuesday the 15th may be on the changeover from high pressure to low. Tropo might be limited to eastern areas for paths across the North Sea to northern Europe.

For EME operators, Moon declination is still negative but will rise to positive by Tuesday night. Path losses are falling towards a minimum at perigee on Thursday the 17th.

So, we have increasing peak Moon elevations and longer Moon windows with the lowest loss for the coming week. 144MHz sky noise is low for the rest of the week.

And that’s all from the propagation team this week.

GB2RS News

Sunday the 6th of October

The news headlines:

• The deadline for advance tickets for the RSGB 2024 Convention is tomorrow, Monday the 7th of October
• The RSGB is interested in what you did for National Coding Week
• The RSGB’s next Tonight@8 webinar will take place tomorrow, the 7th of October

The theme for this year’s RSGB Convention is “Your Convention, Your Way” and the Society is providing a range of activities and presentations as well as different ways to get involved. There is still just time to buy your tickets in advance, but hurry as advance sales for attending the Convention or the dinners closes tomorrow, Monday the 7th of October. You will be able to buy a Convention ticket on the door but not at the discounted rate that is available now. At the event, there will be a varied programme of presentations regardless of your amateur radio interests or experience, as well as practical workshops and Morse competency tests. You’ll also find a room full of special interest groups to chat to who could inspire you to try something new! If you’re unable to travel to the Convention, a small number of presentations will be live-streamed and will be available on the RSGB YouTube channel without the need to pre-register. The RSGB has released two ‘Convention Chat’ videos recently and will be releasing two more over the coming week, so find out what others think of the Convention and see who you might bump into in the bar! For full programme details and speaker information and to book in advance, go to the RSGB Convention web pages at rsgb.org/convention

Did you take part in National Coding Week this year? The RSGB had nine activities to inspire you to take part, including two new worksheets developed by the Society’s Outreach Team. Whether you took part by yourself, at a club night, or with friends and family, the RSGB would love to hear from you. To be included in the RadCom December feature on National Coding Week please send a summary of your activity, along with any photos, to radcom@rsgb.org.uk by the 17th of October. The worksheets will remain on the RSGB website for people to try, so if you would still like to have a go head over to rsgb.org/coding and get involved.

The next RSGB Tonight@8 live webinar is tomorrow, Monday the 7th of October. Ian White, GM3SEK will present ‘Aircraft Scatter, the Hitch-Hikers Guide’. Aircraft scatter is about bouncing VHF and UHF radio signals off high-flying aircraft – effectively ‘hitching a ride’ with someone else’s plane to extend your everyday working range up to 800km. It may sound rather technical, but with some explanations from Ian, aircraft scatter might soon feel very easy. During the talk, Ian will consider how aircraft scatter works, and if it’s so useful, why haven’t we heard more about it? Join the webinar live at 8 pm on the RSGB YouTube channel or special BATC channel. Find out more about this and other webinars on the RSGB website via rsgb.org/webinars

grid.radio is a web application born out of the frustration that Rose, 2E0RXO and many others experienced during spontaneous, often unplanned, Parks on the Air activations. During busy moments, someone would inevitably ask for a Worked All Britain square or another reference that she wasn’t prepared for. There wasn’t a single, simple resource to quickly gather this information with a fast-loading, modern interface. Many websites would spend more time loading advertisements than displaying the necessary information, delaying communication and increasing the pending pile-up. After several months of facing the same issue and finding herself still unprepared, Rose, a Computer Science graduate, decided to solve the problem with code. She created a fast, free web app that can be installed on the home screen of any phone or tablet or accessed on a desktop computer for pre-activation planning. You can also share links so others can easily find out where you are operating from. Once installed, the app will even work without a data connection. Development is ongoing, with feedback from all amateur radio operators welcomed via the contact details on Rose’s QRZ.com page. To learn more about this useful web app visit grid.radio

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 3rd of October 2024

In the first week of October, the 10m band began to show what it is capable of. With a solar flux index in the high 200s and calm geomagnetic conditions, DX was plentiful.

Nick, VK9DX on Norfolk Island was audible on SSB all morning on Wednesday the 2nd and only wanted to work G stations. This made him popular in the UK, but less so in other countries!

Vlad, 5H1WX, on Mafia Island, Tanzania, was another strong signal on the morning of the third. Meanwhile, the 3D2V Rotuma Island DXpedition near Fiji on the 10m band using FT4 was another catch for many people.

The Kp index managed to remain low for the first half of the week, but there were warnings that a coronal mass ejection, which was attributed to the X7.1 solar flare on the 1st of October, might upset things later in the week.

With a good spread of sunspots, mainly in the Sun’s southern hemisphere, there could be more flares over the coming days.

Scott Mcintosh, the solar physicist who predicted a busier than average Cycle 25, has now questioned whether we are past solar maximum. The fact that there are now fewer sunspots in the Northern Hemisphere suggests that we may be past the peak, but only time will tell.

Meanwhile, NOAA predicts the solar flux index may decline towards the 200 mark next week. The Kp index is predicted to go to 4 this weekend. With four of the ten active sunspot groups now classed as growing, we may expect further solar activity and geomagnetic disturbances over the next seven days.

And now the VHF and up propagation news from G3YLA and G4BAO

The brief period of high pressure that arrived towards the end of the previous week is currently being nudged away to the east into Europe.

The coming week is dominated by very unsettled conditions with a succession of deep lows near or crossing the country and there’s even one that contains the remnants of an old hurricane.

The result is that next week will provide copious amounts of wet and windy weather, so no Tropo for us, but there may be several areas of heavy rain for a try at rain scatter on the GHz bands.

We hope you have all checked out your antennas after last week’s reminder since the winds may be quite testing for some areas.

The solar conditions have been stirred up recently by several flares so, as usual, keep an autumn watch out for auroras.

Lastly, there are plenty of meteor scatter opportunities aside from any random meteor activity. Try investigating one of the many meteor websites to see the full list of options.

For EME operators, Moon declination is at its minimum on Wednesday. So, it is a good week for checking out systems before the Sun also gets too low in the sky to make sensible Sun noise measurements over the winter. Path losses are still high but starting to fall.

If you’re fortunate to have a clear low horizon you’ll make some contacts, but with peak Moon elevation only eight degrees on Wednesday, you’ll be lucky! 144MHz sky noise in general is high to moderate for the rest of the week.

And that’s all from the propagation team this week.

The news headlines:

• There is still time to book tickets for the RSGB 2024 Convention
• The RSGB is helping to promote JOTA activities in October
• The RSGB has responded to a recent Ofcom Consultation concerning the 2.3GHz band

With just two weeks until the RSGB Convention, this year’s event is the place to go if you are interested in anything and everything to do with amateur radio. There will be a host of expert speakers presenting on topics ranging from Sporadic-E and how to use AI to write amateur radio applications, to panel debates on amateur radio modes and presentations on inspiring the next generation of radio amateurs. The presentation summaries and speaker biographies are now available on the RSGB speaker page. AMSAT-UK has started to release news of its presentations too and you can see those on the RSGB’s Convention programme. There really is something for everyone. If you haven’t already bought your ticket, be sure to secure it by Monday the 7th of October when the online booking process will close. Buying tickets before the event will save you up to £5 off the usual 'on the day' ticket prices. Due to demand, the RSGB has also arranged an extra introduction to microcontroller programming workshop that will take place on the Sunday morning. There are still some tickets available for Saturday’s Gala Dinner too. To book your tickets for any part of the weekend or to find out more about the programme go to rsgb.org/convention

Jamboree on the Air, also known as JOTA, is taking place between the 18th and 20th of October. The event promotes friendship and global citizenship and is a brilliant celebration of amateur radio among the groups within the Scout Association. Some groups have already shared details of activities that will be taking place over the weekend and the RSGB plans to compile and share a list of these on its comms channels. If you are part of a Scouting group and are planning to get involved with JOTA then please get in touch via comms@rsgb.org.uk with a summary of your station name, callsign and any other relevant information.

The RSGB has responded to a recent Ofcom Consultation which would see new users sharing spectrum within the 2.3GHz amateur band. Whilst the new devices may be limited to indoor use, the RSGB has taken the opportunity to highlight concerns regarding the weak signal 2320MHz segment. In addition, the RSGB has also indicated its wish to review the current restrictions that apply to this band that date back to 2013, when it was subject to Public Sector Spectrum Release. The response and background information can be found in the Spectrum Forum web pages at rsgb.org/spectrum-forum

The October edition of RadCom includes an article about the very first two-way radio communication between the UK and New Zealand, something that Sir Edward Appleton, radio physicist and Nobel laureate, later described as “probably the most dramatic moment in the history of the development of the short waves.” The contact was between two radio amateurs, one in Mill Hill School, London and the other on a sheep farm in New Zealand. Centenary celebrations will be taking place in New Zealand and at Mill Hill School, and special event callsigns will be active from today until late October. GB2NZ and ZM100DX will be active each day during that period and, for the week of the centenary, the near-actual callsigns used in 1924, G2SZ and ZL4AA, will be active from the 14th to the 20th of October. A commemorative certificate will be available for those who make contacts with the event stations. For more information on the Goyder-Bell award, and to find out more about the centenary celebrations, go to gb2nz.com

Lots of amateur radio stations are on the air this weekend for the Railways on the Air event. The occasion marks the anniversary of the first steam-powered passenger railway journey which took place on the 27th of September 1825. The first passenger train ran on a line in the North East of England from Darlington to Stockton. Activity will be centred around 3.65, 7.15 and 14.25MHz. For more information visit rota.barac.org.uk

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Wednesday the 25th of September 2024

Solar activity is back to moderate levels with an M3.7 solar flare detected on the 22nd of September. Newly assigned AR 3835 in the southeast quadrant is the main source and the event looks to have thrown a stream of plasma into space.

The latest model suggested a possible passage near our planet by the 25th and it looks like the prediction was correct. The Space Weather Prediction Centre issued a G1 geomagnetic storm watch and visible aurora may be likely at very high latitudes. Expect maximum useable frequencies, or MUFs for short, to decline if the Kp index is above 4 or 5.

Other than a large number of C-class solar flares in the past five days, this was the biggest eruptive event to occur.

The solar flux index had declined to 172 on Wednesday the 25th but is unlikely to decrease much further. Note that nearly all the sunspots are in the Sun’s southern hemisphere at the moment.

Meanwhile, daytime MUFs over a 3,000km path are now consistently over 28MHz under quiet geomagnetic conditions. This is good news for fans of the 10m band. Night time MUFs over 3,000km are around 14 to 16MHz, so it looks like we may soon lose the 24-hour DX openings on the 20m band, which are prevalent in the summer months.

Increasing solar proton flux at the moment means paths over the Arctic Circle may be compromised.

Daytime critical frequencies remain over 8MHz and often reach nearly 11MHz, so NVIS communications around the UK on the 40m band remain commonplace but may disappear later in the evening.

NOAA predicts that the solar flux index will increase next week but may not reach the 200s. Keep an eye on solarham.com for daily updates.

And now the VHF and up propagation news from G3YLA and G4BAO

The present run of unsettled weather has become firmly established and, although many parts of the country have not seen the torrential rain and flooding of last week, there will be some rain at times in most parts of the country during the first week of October.

There are a couple of brief periods in the models when a weak ridge of high pressure is due to cross southern areas, but these are not seen as great for Tropo.

The week beginning Monday the 30th of September sees at least two major lows pass close to northern Britain. One occurs as this weekend draws to a close and there may be another one later in the week. These types of changeable patterns are notorious for problems with detailed predictions beyond a few days, although the general weather type is well forecast.

Just a reminder that strong wind events at the end of a long summer can be a big shock to antennas, so now is a very good time to check that all is well in the guying department.

Having discounted Tropo as an option, the obvious choice will be rain scatter on the GHz bands, but some of these events may produce very fast-moving echo sources. So, it could be quite a challenge although last week saw plenty of good rain scatter conditions.

Meteor scatter is again largely dependent upon random meteors with just a couple of lesser showers, the Kappa Leonids and Sextantids, which see out the end of September.

The auroral situation continues to provide some excitement, and the autumn months are a good time of the year for such things.

For EME operators, Moon declination is still positive until Tuesday evening, so Moon visibility windows are shortening. Path losses are high with apogee next Wednesday the 2nd of October. Thursday the 3rd sees near-eclipse conditions when the Sun and Moon are close in the sky meaning high noise with wider beam width antennas. 144MHz sky noise is, in general, low for the rest of the week.

And that’s all from the propagation team this week

GB2RS News

Sunday the 22nd of September

The news headlines:

• The RSGB Convention is just three weeks away
• The RSGB has announced that routine bookings for paper exams will cease
• Take advantage of group activity opportunities at the RSGB National Radio Centre

The RSGB Convention is just three weeks away and there is a fantastic programme planned. Whatever your amateur radio interests or experience there will be something for you. In addition to the presentations, you could take part in a workshop to learn more about microcontroller programming – spaces are limited so make sure you book soon if you want to be part of that event. There will also be an EMF and EMC Clinic, contest forums and a chance to find out more about a wide range of amateur radio special interest groups. The social side of the Convention is important too, whether you’re catching up with friends over coffee or enjoying the Gala Dinner on Saturday evening. Day or weekend tickets for the Convention are still cheaper if you buy in advance rather than on the door, and the deadline for advance tickets is Monday the 7th of October. To find out more about the programme, the speakers and to book your tickets, go to the RSGB Convention web pages at rsgb.org/convention

The RSGB has announced that from the 29th of November it will stop taking routine bookings for paper exams. Currently 97% of amateur radio licence examinations are taken online using the TestReach platform, either at home under remote supervision or in a club setting. Following the implementation of Syllabus v1.6 on the 1st of September 2024, the new examination question bank will only be maintained online. Generating paper exams will involve significant additional work for the RSGB Examinations Department, with the associated costs. You will be able to apply for a paper exam on the grounds of special educational needs in the same way that you can currently request special requirements such as extra time or a reader. To do that you need to email the Exams Department via exams@rsgb.org.uk To read the full details of the changes, including the three important dates you need to know, please go to the RSGB website at rsgb.org and search for ‘Exam Announcements’.

Do you work with young people at a school, or perhaps with a youth group such as the Scouts, Guides or Cadets? Are you looking for an activity that provides hands-on learning opportunities for them? The RSGB National Radio Centre currently has availability for two private evening visits in December as part of the Society’s activities for Youngsters on the Air month, or YOTA month as it is often called. Sessions typically last two hours and include an introduction to amateur radio, before the youngsters are split into smaller groups to complete a variety of activities. These can include Morse code, VHF communication using handhelds, shortwave radio communication and satellite communication. The group size is limited to a maximum of 12, and there must be one adult accompanying every four students. If you’d like to find out more about this unique learning opportunity, email the RSGB National Radio Centre Coordinator Martyn Baker, G0GMB via nrc.support@rsgb.org.uk

The next Bletchley Park 1940s weekend is taking place at the moment. If you are visiting for the event, make sure you drop into the RSGB National Radio Centre where you’ll be able to see a number of World War Two receivers on display. Don’t forget that RSGB members can get free entry to Bletchley Park, which also includes admission to the RSGB National Radio Centre. You can access this fantastic offer by logging into the RSGB membership portal via rsgb.org/members and selecting ‘Visit Bletchley Park’.

Don’t forget that National Hamfest 2024 is coming up on the 27th and 28th of September and promises to be an unforgettable celebration of all things amateur radio. As always, the traders and manufacturers are lining up to bring you the best in amateur radio equipment and accessories. Many exhibitors will be offering exclusive deals, making it the perfect time to upgrade your gear or add new items to your shack. For more information and to purchase your tickets, visit nationalhamfest.org.uk

Railways on the Air weekend usually takes place on the weekend closest to the 27th of September. This date celebrates the anniversary of the first steam-powered passenger railway journey which took place on the 27th of September 1825. The first passenger train ran on a line in the North East of England from Darlington to Stockton. Bishop Auckland Amateur Radio Club coordinates the event and this year it will take place over the weekend of the 28th and 29th of September. For more information visit rota.barac.org.uk

The next event in the popular 145 Alive series takes place on Sunday the 29th of September. The event will run from 1 pm to 4 pm and there will be nets operating in most Maidenhead Squares across England, Scotland, Wales and Ireland. To take part in the event, which is designed to promote FM activity on the 2m band, all you need to do is call in and make contact with others. The organisers are looking for more net controllers. For more information contact Mark Savage, M0XIC via the 145 Alive Facebook page.

On Monday the 7th of October the RSGB’s Tonight@8 live webinar will be with Ian White, GM3SEK who will give a presentation entitled ‘Aircraft Scatter, the Hitch-Hikers Guide’. Aircraft scatter is about bouncing VHF and UHF radio signals off high-flying aircraft – effectively ‘hitching a ride’ with someone else’s plane to extend your everyday working range up to 800km. For example, if you are one of the hundreds who get involved in the monthly UK Activity Contests on the 2m, 70cm and 23cm bands, you will already be using aircraft scatter routinely and it will be responsible for some of your best QSOs. So how does aircraft scatter work? And if it’s so useful, why haven’t we heard more about it? Join the webinar live at 8pm on the RSGB YouTube channel or special BATC channel. Find out more about this and other webinars on the RSGB website via rsgb.org/webinars

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 19th of September 2024

It was a topsy-turvy time for HF propagation last week with a declining solar flux index and geomagnetic disturbances thanks to coronal mass ejections, or CMEs, from the Sun.

The solar flux index declined to the mid-160s, and the Kp index had a couple of excursions to more than 7. These were due to CMEs and the second, which occurred on Tuesday the 17th, was associated with the X4.5 solar flare on Saturday the 14th.

Luckily, it was 0300UTC when the CME hit the Earth, so only die-hard UK DXers were affected. With a G4 geomagnetic storm raging, the maximum useable frequency over a 3,000km path fell to less than 6MHz, but did manage to recover to 8.45MHz by dawn.

The rest of Tuesday was subdued with the maximum useable frequency never really getting above 21MHz. This is why the advice is often to avoid DXing when the Kp index climbs high, as the upper HF bands will likely be closed.

By comparison, on Thursday the 19th the Kp index was 2.67 and the maximum useable frequency over 3,000km was above 28MHz again.

NOAA puts the risk of another X-class flare at 10%, and an M-class event at 55%. So, we are not out of the woods yet.

Next week, the Space Weather Prediction Centre says the solar flux index may decline slightly but could then rise to be in the 232 to 240 range. Geomagnetic storming is predicted for the 26th to the 29th, when the Kp index could rise to 5.

Meanwhile, autumnal HF conditions should soon be kicking in with better propagation to North America. If the solar flux stays high, we can expect excellent 28MHz propagation, perhaps to the mid-west and Pacific states.

North-South HF paths, such as the UK to South Africa and South America, should also be good around the equinox period.

And now the VHF and up propagation news from G3YLA and G4BAO

The last week of Tropo gave us good conditions across the North Sea and up and down the country on the VHF and UHF bands.

It is very likely that there will be a big change of weather type over this weekend, ending today the 22nd, to a much more unsettled pattern with low pressure dominating during the coming week.

In fact, there will be a sequence of lows, fronts and showery interludes to set the template for next week. This means that rain scatter is a good candidate for propagation on the GHz bands, which could be useful on the evening of Tuesday the 24th during the SHF UK Activity Contest. Meanwhile, tropo takes a back seat for a while.

The solar activity continues to be of interest and, again, the message is to monitor the Kp index to keep one step ahead of events in case any aurora spring up.

Meteor scatter is mainly down to random activity, although the daytime Sextantids peaks on Friday the 27th of September, but with a low zenith hourly rate of 5.

For EME operators, Moon declination is positive and rising, reaching +29 degrees next Tuesday, so Moon visibility windows will continue to lengthen. Path losses are increasing as we passed perigee last week. 144MHz sky noise is moderate, dropping back to low next Thursday.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 12th of September 2024

Last week showed that HF conditions are improving as we head into the autumn.

With a solar flux index still above 200, there was plenty of DX available to work. CDXC members reported working VP6WR on the Pitcairn Islands, KH8T on American Samoa and 3D2USU on Fiji, which is not a bad catch for early September.

A little closer to home, 9A168TESLA in Croatia has been popping up for short periods celebrating the 168th anniversary of the birthday of electrical pioneer Nikola Tesla. Watch DX Summit closely for operating times.

The daylight maximum useable frequency, or MUF, over 3,000 kilometres remains above 28MHz on the whole, although a raised Kp index tends to reduce this.

Geomagnetic conditions remained relatively calm with the Kp index below 3 all week. That changed on Thursday the 12th as material from a coronal mass ejection, or CME passed the ACE spacecraft in the early hours.

The solar wind speed increased to more than 500 kilometres per second and the Bz swung south. On Thursday the 12th, the Kp index was 5 and the Met Office Space Weather department was forecasting potentially unsettled conditions for this weekend, ending today the 15th.

At the same time an X-class flare occurred, with lowered MUFs due to increased D-layer absorption.

Two large coronal holes on the Sun’s surface are also now Earth-facing and threaten to add to the solar wind this weekend.

According to NOAA’s predictions, the solar flux index should stay in the 210 to 225 range next week, although a large number of spots are about to rotate off the Sun’s visible disk.

This may be compensated by an active region that’s about to rotate into view. This has been emitting C-Class and lower-level M-flares and could potentially be the same region that produced several energetic eruptions off the far side of the Sun over the past week. Time will tell.

And now the VHF and up propagation news from G3YLA and G4BAO

The heavy showers at the end of last week produced some good rain scatter, but no QSOs in the UK were noted due to the showers not coinciding with GHz contests and few suitable home stations were active to take advantage of them.

After a gradual build-up of pressure over this weekend, ending the 15th, high pressure is suggested by most models during the coming week. However, there is some uncertainty about the position of the high.

Currently, models are favouring the north of Britain and this means that in the south, although still on the edge of high pressure, there could be a brisk northeasterly breeze, which may weaken the inversion prospects. It’s not clear if the Tropo will be functioning in time for the 70MHz Affiliated Societies Contest today, the 15th, but should be helpful for the 1.3GHz UK Activity Contest on Tuesday the 17th and the 70MHz UK Activity Contest on Thursday the 19th.

Solar conditions are still likely to offer the chance of the occasional elevated Kp index, which is a good sign of possible aurora. It will be interesting to see how things evolve this weekend, ending the 15th, as a series of expected CMEs are due to reach Earth.

The amateur bands between 10m and 2m are the ones to check as well as looking out for ‘watery’ sounding signals on the HF bands. Remember it doesn’t have to be dark for radio aurora, so don’t wait for dusk before checking.

Meteor scatter is mainly down to random activity in the coming week. However, with the September Epsilon Perseids stream still active until the 21st, having peaked on the 9th, conditions may be slightly enhanced.

For EME operators, Moon declination is negative but rising and going positive again on Wednesday the 18th. Moon visibility windows will continue to rise while path losses decrease as we approach perigee on Wednesday the 18th. 144MHz sky noise is moderate for the whole of next week.

And that’s all from the propagation team this week.

The news headlines:

• Book your RSGB Convention tickets now
• There are several vacancies in the RSGB’s Regional Team
• Remember to call in to the CHOTA stations on Saturday

The RSGB Convention is just five weeks away and an exciting programme of presentations and practical activities is being prepared. The early bird price for day tickets ends on the 15th of September and this year there won’t be any extensions to that date! As well as three streams of presentations across the weekend there will be an introductory workshop on microcontroller programming. This workshop is part of the Society’s aim to widen the programming skills in the amateur radio community and to introduce people to something new. On Saturday morning RSGB experts will give an EMC and EMF update presentation, followed by an informal EMC and EMF clinic in the afternoon. The RSGB HF and VHF contest forums will take place on Sunday. Throughout the weekend there will be opportunities to talk to RSGB representatives and to members of many special interest groups who could inspire you to try a different aspect of amateur radio. The RSGB 2024 Convention – your convention, your way. To book your day tickets and to book for the workshop, go to rsgb.org/convention

The RSGB has 13 regions, each covered by a Regional Representative and a team of District Representatives. This volunteer team is an important link to clubs and a potential source of support and information for individual radio amateurs. There are several vacancies in the Regional Team and this month we’re highlighting two regions. In Region 5 there is an opportunity for someone to volunteer as a District Representative covering Gloucestershire, Hereford and South Worcestershire. There are also two vacancies in Region 13 for District Representatives to cover Leicestershire and Rutland, and also North Lincolnshire. If you’re interested in supporting local radio amateurs and clubs in those areas, please contact the appropriate Regional Representative. You can find their details by going to our website at rsgb.org/regions and clicking on the region in which you live.

Next Saturday, the 14th, lots of amateur radio stations will be on the air to take part in the Churches and Chapels on the Air event, also known as CHOTA. The event will take place from 10 am to 4 pm and operation will be focused on the 80, 40 and 20m bands. To see the list of churches and chapels taking part visit the ‘CHOTA’ tab on the World Association of Christian Radio Amateurs and Listeners website at wacral.org

Several changes have been made to the RSGB contest trophies process, for logistical and resource reasons. For example, instead of engraving each trophy, the winner will be presented with a quality certificate at the Trophy Presentations on Sunday morning at the RSGB Convention. For each award, a high-quality photograph will be taken of the winner with their trophy, and that photo will be available for the winner if they would like it. RSGB HQ will now administer all trophies for the AGM event. The full changes are shown in the updated trophy policy on the RSGB website at rsgb.org/trophies If you have any questions about these changes, please contact the RSGB Trophy Manager Mike Franklin, G3VYI via trophy.manager@rsgb.org.uk

Over the course of a year, radio amateur Maggie laquinto, VK3CFI attempted to make contact with Russian cosmonauts on the Mir space station. Maggie used her amateur radio skills and equipment to monitor the orbit of the space station and listen to the frequencies that it used. After the dissolution of the Soviet Union in 1991, Maggie relayed crucial information to cosmonaut Sergei Krikalev. In a recent BBC programme, Maggie’s son Ben laquinto speaks to Megan Jones. You can listen to the programme by searching for ‘The woman who spoke to the space station’ on the bbc.co.uk website.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 5th of September 2024

Last week was underlined by continued high solar flux indices and excellent 10m band propagation to CY9C on Saint Paul Island near Newfoundland.

The DXpedition, which has now ended, was often at S9+ on 28MHz up to two hours after sunset. This may be a sign that better autumnal HF conditions are just around the corner and bodes well for the rest of the year.

The average sunspot number has now exceeded 200 for the first time in 23 years. This puts it significantly better than Solar Cycle 24 and it looks like there is more to come.

Propquest.co.uk reports that maximum usable frequencies over a 3,000km path are now often above 28MHz, so look out for DX on the 10m band. This will improve as the month goes on. September is a good month for north-south paths and paths to North America will improve as we head into October.

So, get your higher HF band antennas sorted out, as this autumn could be fun!

During the week just past, there were 21 M-class flares, but no X-class events. The Kp index has been under 5 all week, which no doubt helped HF propagation flourish.

Large coronal mass ejections, or CMEs, did occur on the 1st and 3rd of September, but these appear to be related to far-side events, well beyond the northwest limb and were directed away from Earth. But that active region is now rotating into view so buckle up for potential Earth-directed CME activity.

Next week, the Space Weather Prediction Centre suggests that the solar flux index will remain in the 240 to 250 range. Unsettled geomagnetic conditions are forecast for today, the 8th of September but, as we always say, keep an eye on solarham.com for up-to-date solar information as things are likely to change each day.

And now the VHF and up propagation news from G3YLA and G4BAO

The slightly enhanced Tropo conditions were welcome for the 144MHz UK Activity Contest on the 3rd of September. However, in the coming week, the opposite is now the case for many parts of the country as low pressure is set to dominate the weather charts.

There may be some weak ridges of high pressure nearby or even over northern Britain this weekend, but it is not looking great.

If pressed for a direction, it looks better across the North Sea to northern Europe and southern Scandinavia in the first part of the week.

Much of next week will have low pressure in control, and it will be worth looking for rain scatter on the GHz bands.

The solar side of things means that we should be alert to the chance of aurora if the Kp index rises. The autumn is often a good time of the year for these. It will be useful to monitor the Kp index, especially if you hear any signals sounding ‘watery’ on the HF and LF bands.

It’s always worth a reminder that the Sporadic-E season does not drop off a cliff at this time of year. That said, it does become very infrequent and restricted to lower bands or digital modes under the influence of jet streams. The southward paths to Iberia and the western Mediterranean look most promising next week for an out-of-season chance Sporadic-E event.

There is one small meteor shower this week. The September Epsilon-Perseids peaks with a low zenithal hourly rate of five tomorrow, the 9th. This shower produced unexpected outbursts in 2008 and 2013, but modelling indicates that 2024 activity should be nothing unusual.

For EME operators, Moon declination is now negative and falling further, reaching minus 29 degrees next Wednesday. Moon visibility windows continue to fall, as will peak Moon elevation, while path losses are decreasing after apogee. 144MHz sky noise increases from moderate today, the 8th, reaching over 2,500 Kelvin next Wednesday.

And that’s all from the propagation team this week.

We are delighted to announce that the Radio Society of Great Britain and ARISS, in conjunction with Girlguiding Surrey West and Brooklands Museum including the Innovation Academy, have been collaborating on a special event due to take place on Saturday the 5th of October. Girlguiding President, Her Royal Highness The Duchess of Edinburgh will attend a planned contact with the International Space Station as part of a visit to promote the engagement and involvement of girls and young women in science, technology, engineering and maths. Further details of the contact and the event will be announced in late September.

The RSGB’s autumn Tonight@8 programme starts this Monday, the 2nd of September. Brian Coleman, G4NNS will give an update on the Meteor Beacon Project which is a cooperation between the worlds of amateur radio and astronomy. The first phase of this project was completed in May 2022 when the UK meteor beacon GB3MBA went on the air from the Sherwood Observatory of the Mansfield and Sutton Astronomical Society. It enabled studies of meteor events over the UK using simple equipment and made possible a range of STEM projects featuring radio and astronomy. The second phase of the project, which Brian will describe in the presentation, is to develop a network of receivers streaming their data via a central server for detailed studies of individual meteor events. You can watch and ask questions live on the RSGB YouTube channel or a special BATC channel. To find out more go to the RSGB website at rsgb.org/webinars

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 29th of August 2024

We had a good week for HF propagation, at least until we had a Kp index of 5.67 on Wednesday the 28th. This was caused by the Bz component of the interplanetary magnetic field moving into a south-pointing position.

Luckily, it didn’t last long and geomagnetic conditions were back to normal by Thursday.

The solar flux index remains above 200 with no sign of it dropping. But solar flare activity has not diminished either with 16 M-class flares over the past seven days and more than 60 C-class events. There remains a 55% chance of a further M-class flare and a 10% chance of an X-class event.

Tuesday the 27th saw some good activity on the upper HF bands with the 10m band opening up at times. VK has been heard on 28MHz in the mornings, which bodes well for the coming months.

The top DX choice this week has been CY9C on Saint Paul Island near Newfoundland. The team is active on all bands until the 5th of September using CW, SSB, FT8, Super Fox and RTTY. VOACAP Online shows that the 20 and 17m bands offer the best chance for a contact and are open from 0900 to 2000 UTC. The 30m band is another strong contender from 2000 to 1000 UTC.

Next week, NOAA predicts that the solar flux index will start at around 250 but could end the week at 275. As always, it estimates the Kp index will be at 2 all week, but this will depend upon coronal mass ejections, so keep an eye on solarham.com for daily updates.

If a solar flare and associated coronal mass ejections do occur, expect the Kp index to rise after about 48 hours, with a lowering of the maximum useable frequency.

And now the VHF and up propagation news from G3YLA and G4BAO

The autumn season usually brings thoughts of Tropo since areas of high pressure can often be a feature of this time of year. Most models predict that there will be high pressure moving in to offer Tropo conditions today, the 1st.

Thereafter, the models differ, and some bring low pressure over the country for much of the coming week, while others maintain a high-pressure story and the continuation of Tropo.

This is potentially useful for the 144MHz UK Activity Contest on Tuesday and Wednesday and, if it lasts, the 144MHz Trophy Contest next weekend along with the Backpackers contest on Sunday the 8th.

With the uncertain feel of the forecast at the moment, we may find rain scatter is the main option on the GHz bands.

Meteor scatter is again reduced to non-shower random events with just a minor shower, the Aurigids, peaking on the 31st of August. This shower has produced brief unexpected outbursts with a zenithal hourly rate of around 30 to 50 per hour in 1935, 1986, 1994 and 2019.

Random meteor flux is at its annual maximum in September with relatively good rates, especially during morning hours. Pre-dawn is the best time to try.

The solar conditions continue to provide chance auroras. Keep one eye on the Kp index and lock the frequency of some northern European beacons into your rig’s memory.

Lastly, it's the nominal end of the 2024 summer Sporadic-E season and the daily blogs on Propquest have finished. However, some years can produce surprise Sporadic-E events during the first week of September.

Moon declination starts the weekend still high but falling, going negative again on Thursday the 5th. So, Moon visibility windows will also fall, as will the peak Moon elevation.

Moon apogee is also next Thursday so path losses are still increasing. 144MHz sky noise is low until Monday but, shortly after moonrise that day, the Sun and the Moon become close in the sky and continue to be until after moonset on Tuesday.

This means sky noise will be very high, especially at VHF, due to wide antenna beamwidths.

And that’s all from the propagation team this week.

Sunday the 25th of August 2024

The news headlines:

• The RSGB 2024 Convention will feature a microcontroller programming workshop
• You can take the RSGB Morse competency test at National Hamfest this year
• RSGB Board Director Peter Bowyer, G4MJS to take on Board Liaison roles for contesting and trophies

At this year’s RSGB Convention, there will be a workshop to introduce attendees to microcontroller programming through a short presentation followed by practical exercises. The Society aims to widen the programming skills in the amateur radio community and introduce individuals to radio-related usage of Micro Controller Units, or MCUs. If you attend the workshop, you will receive a genuine Arduino board, a set of DuPont wires, a breadboard and two specific devices which you will be able to take away with you at the end of the workshop. The exercises will take you through using the Arduino IDE, basic programming and interfacing to the provided devices. You need to pre-register as spaces are limited to just 20 people. The workshop and hardware are free, but in return for the £10 booking fee, you will receive a copy of the book “Microcontroller Know How” by Mark Jones, G0MGX. You must be a ticket holder for the Convention to be able to take part. To find out more and to book your place, go to the RSGB website at rsgb.org/convention and choose the workshops and forums tab on the right-hand menu.

If you’re going to the National Hamfest on the 27th and 28th of September, why not try the RSGB Morse competency test? You don’t have to book in advance, just visit the RSGB village area. You can be tested at 10, 12, 15, 20, 25 or 30 words per minute so you don’t have to be a CW expert. If you pass the test, you’ll either receive a certificate on the day or it will be sent to you electronically shortly after. Eric Arkinstall, M0KZB is the RSGB Morse Competency Project Lead and he will guide you through the test process. If you don’t want to do the test you can still drop in to try Morse for the first time or pick up some hints and tips. It will be a busy event so whilst there will be headphones available, you’re welcome to bring your own if you prefer. Eric looks forward to seeing you at the event! If you have any questions, please contact Eric via morse.tests@rsgb.org.uk

The RSGB Board Chair has announced that new Director Peter Bowyer, G4MJS will take on the Board Liaison roles for contesting and trophies. If you would like to contact Peter, his email address is g4mjs@rsgb.org.uk

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 22nd of August 2024

We had yet another week with a high solar flux and relatively calm geomagnetic conditions.

The solar flux index ended up at 239 on Thursday the 22nd, while the Kp index has been below 4 since Sunday the 18th. There are currently 11 active sunspot regions on the Sun’s surface and there is a 20% chance of a major X-class solar flare according to the NOAA Space Weather Prediction Center.

There are signs that HF propagation may be improving, but it will probably be another month or so before we see any large change. This is due to the summer doldrums that see the ionosphere harder to ionise due to a change in its chemical composition.

By mid to late September, we will start to see a change to autumnal conditions and DX will start to open up again on the higher bands. Having said that, there is still DX to be had. The N5J DXpedition to Jarvis Island in the Pacific Ocean proved that the DX is workable, but the path was mainly open to well-equipped stations with beams and linear amplifiers.

15m remains the best DX band and there are occasional openings on the 12m band. The 10m band may come into its own as we head into September and October.

According to the NOAA Space Weather Prediction Center, solar cycle 25 likely reached its highest sunspot number yet of at least 299 on the 8th of August. This may increase further, but we may be close to solar maximum.

Next week, NOAA predicts that the solar flux index will remain around 200 to 210. Geomagnetic conditions will depend almost entirely on the occurrence of coronal mass ejections, or CMEs. And, as we are at a particularly active part of the solar cycle, flares and CMEs are very prevalent.

And now the VHF and up propagation news from G3YLA and G4BAO

The overview for the coming week is that, although some fronts will affect the north and west at times, there are only a few that reach down to the southeast of Britain. This means that rain scatter is more likely in northern areas.

There will be weak high pressure over southern areas for much of the coming week and, although not enough for a full-blown Tropo event, conditions should be a little ‘up', especially for paths into the near continent or across the North Sea.

Meteor scatter is back to a more random approach since the broad peak of the August Perseids comes to an end. The solar conditions mean that auroras can be a possible element of operating excitement in the coming week. Remember to look out for a disturbed Kp index value of 6 or greater.

The last part of the sporadic-E season is playing out this week taking us to the end of the month. These 'last hurrahs' are usually characterised by QSOs of very limited duration on the 10m band, or perhaps up to 6m, and mainly over the southern half of Europe.

This usually favours southern UK stations but, notwithstanding the previous comments, some years have seen isolated Sporadic-E events in the first part of September. But they are certainly not reliable.

Moon declination is positive but still rising, reaching maximum on Wednesday, so long Moon visibility windows and high peak elevations continue. We are past perigee now, so path losses are increasing again. 144MHz sky noise is low but increasing to a moderate 500 Kelvin on Wednesday before falling back to low at the end of the week.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 15th of August 2024

Last week was notable for its auroral activity, high solar flux index and variable HF conditions.

Monday the 12th saw the Kp index rise to 7 as coronal mass ejection material struck the Earth, sparking visible aurora as far south as Cornwall. But by lunchtime on Tuesday things were back to normal with a Kp index below 2.

The rest of the week remained fairly settled with the occasional blip up to a Kp index of 4. Meanwhile, HF conditions have been variable with N5J on Jarvis Island in the Pacific being the main DX being chased. This has turned out to be a difficult catch for all but the better-equipped stations in the UK.

The operators are active on SSB, CW and FT8, using the SuperFox and Fox and Hound modes, and are working until the 20th of August. So, have a listen and give them a call.

The peak times are around 0500 to 1200UTC for a short-path contact, and around 1800UTC for a long-path contact. See jarvisisland2024.com for frequency details and the latest news.

Otherwise, the maximum useable frequency, or MUF, over a 3,000km path has been more than 18MHz and often 21MHz during daylight. Night-time MUFs have been more than 14MHz when there have been no geomagnetic disturbances.

Next week, NOAA predicts that the solar flux index will start at around 260 but decline to perhaps 210 as the week progresses. This is still enough for some good HF propagation. Predictions are less certain about geomagnetic disturbances, other than a rise on the 22nd of August.

Solarham.com predicts that a coronal mass ejection associated with an X1.1 solar flare last Wednesday will pass Earth by the 18th of August, so we may expect the Kp index to rise today.

And now the VHF and up propagation news from G3YLA and G4BAO

The period of alternating hot summer days and unsettled spells with rain or heavy showers looks like the recipe for the coming week.

The weak ridges of high pressure could prove useful for some Tropo on occasion. In the summer months, Tropo is often more pronounced over nearby waters such as the North Sea and south across Biscay or the English Channel. But it can also feature overnight and, if we are lucky, may help with the 23cm UK Activity Contest on Tuesday the 20th.

These high-summer active fronts or heavy showers can be very good for rain scatter. Since temperature plays an important role in the intensity of summer thunderstorms, the resulting rain scatter is often best in the afternoon and early evening. On rare occasions, daytime storms can drift north from France to be over the UK during the night.

The Perseids meteor shower peak has passed now, with some good QSOs reported. It’s a broad shower and there should still be some worthwhile meteor input to play meteor scatter next week.

The recent solar conditions have produced a disturbed Kp index and there were some impressive visible and radio auroras from 10m up to 6m last week. It's worth watching out for a high Kp index above, say, 6 and be ready to listen for radio Aurora in the afternoon.

Lastly, the Sporadic-E season struggles on with varying degrees of success, but it's still very much a player for another two or three weeks. The upper air charts show that there should be some strong jet streams and thus potentially good sources of the turbulence required for Sporadic-E. Use the Propquest.co.uk NVIS graphs to see if Dourbes in Belgium is showing any spikes.

Moon declination is negative but rising now. It won’t go positive until Wednesday, so short Moon visibility windows and peak elevation continue to increase. Wednesday is also perigee, the Moon’s closest point to Earth and when path losses are at their lowest. 144MHz sky noise is moderate to low over the coming week.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 8th of August 2024

Well, so much for the experts! NOAA predicted that the solar flux index would fall last week when it increased to a whopping 303 on Thursday the 8th.

But this high solar flux number was accompanied by a strong risk of solar flares, so it was not all plain sailing. We have had 15 M-class and two X-class solar flare events over the past three days and the threat remains high.

Coronal mass ejection activity on Wednesday resulted in NOAA and the Space Weather Prediction Centre warning of possible moderate G2 geomagnetic storming towards the later part of week ending the 11th of August. This could see the Kp index rise and the maximum usable frequency fall.

Hopefully, conditions will improve after the weekend.

Last week was a good one for HF propagation with a high solar flux index and low Kp index. The 10m band was open to Brazil in the late afternoon, and this appeared to be F2-layer propagation and not multi-hop Sporadic-E.

Meanwhile, the 15m band has perhaps been the DX band of choice with long openings to the Far East, at least on FT8, and North America at the same time. HF conditions should also improve as we move into September, but more on that closer to the time.

Attention now shifts to N5J on Jarvis Island, an uninhabited 4.5-kilometre-squared coral island in the South Pacific Ocean, about halfway between Hawaii and the Cook Islands. The DXpedition is active on all bands and their website at Jarvisisland2024.com can provide you with personalised propagation forecasts – let us know if you work them.

Using Proppy at soundbytes.asia or VOAcap at voacap.com, shows that 20, 17 and 15m short-path seem to offer the best chance of working the DXpedition, with morning openings from around 0600 to 1000UTC. There is also a potential long-path opening between 1800 and 2000 UTC, with a possibility of the 10m band at 1900 UTC. Both are near polar paths and may be adversely affected by a high Kp index.

CDXC members with good stations have already reported QSOs with N5J on the 17m band using FT8.

Next week, NOAA predicts the solar flux index will be in the range of 185 to 240. Geomagnetic conditions will depend on whether we have more solar flares and coronal mass ejections, and the chance of those remains high.

An Earth-facing coronal mass ejection could send the Kp index soaring, and that will no doubt lead to reduced maximum useable frequencies and noisy bands. So, fingers crossed for more quiet geomagnetic conditions and low Kp indices!

And now the VHF and up propagation news from G3YLA and G4BAO

The summer tries to deliver but, overall, the pattern has a rather unsettled flavour to it for the coming week.

On the positive side, we see a transient area of high pressure crossing southern Britain over this weekend, ending today the 11th. This could give some Tropo conditions but, after this, the Atlantic westerly flow brings a succession of fronts and showers to most areas.

In terms of propagation, this suggests that rain scatter will have the best of it in the week ahead.

The Sporadic-E season remains a good fallback and surprised us in East Anglia mid-morning on Tuesday the 6th of August with 144MHz Sporadic-E propagation to YU, HA, 9A and LZ moving around towards Italy as the opening progressed.

All were workable with 100W and a white stick antenna on FT8. For the coming week, the jet stream activity will probably start by favouring paths to Scandinavia and the Baltic. Later in the week, a new jet stream will drive southeast into Iberia, opening up chances for paths to EA and CT.

The Perseids meteor shower this week will provide welcome new fuel for Sporadic-E and, as a result, like most years, we’ll see openings into the first week of September.

The meteor scatter highlight is the Perseids meteor shower, which peaks on Monday and Tuesday. So, there are plenty of opportunities to try a new mode or fill in some missing grid squares if you are already involved in meteor scatter.

Many websites explain what it's all about, but one to start you off is g7rdx.co.uk Also, try looking for videos of meteor activity on SDR radios to get an idea of what it all sounds like.

The solar conditions lately have been rather disturbed. It would not be surprising if the Kp index was to suggest that aurora could be a possibility if it gets to 5 or higher.

Moon declination is negative and reaches minimum on Thursday the 15th, which means there will be short Moon visibility windows and low peak elevation. Path losses will decrease throughout the week and 144MHz sky noise is low over the weekend, but climbing to reach a high peak of over 3200 Kelvin on the 15th.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 1st of August 2024

We had another week of high solar flux but unsettled geomagnetic indices.

The solar flux index, or SFI, was above 200 from the 27th of July onwards. There was a worry that multiple coronal mass ejections, or CMEs, might push the Kp index up during the week. In the end, the Kp index didn’t rise above 5. But why was that?

The first of several CME eruptions was expected to pass Earth on the 29th of July. The solar wind speed increased from 330 kilometres per second to around 450 kilometres per second, but only a brief period of minor G1 geomagnetic storming was observed. The solar wind stream was fast, at more than 450 kilometres per second, but its frozen-in magnetic field was predominantly North-facing or neutral. So, it didn’t couple with the Earth’s magnetic field, and we ended up with a Kp index of only 5.

If we had had a south-facing interplanetary magnetic field or Bz it could have been much worse.

As it was, the ionosphere was affected on Wednesday the 31st of July. However, by 1830UTC things were back to normal, with a critical frequency of 7.4MHz, which gives a maximum usable frequency over a 3,000km path of around 21MHz.

Further disturbances on Thursday the 1st of August saw the Kp index rise to 5 again, but it was short-lived and only lasted for one three-hour period.

So, we are still in a period of high solar activity, with numerous M- and even X-class flares, coronal mass ejections and high sunspot numbers. With a cluster of sunspots rotating into view right now, it should be an interesting week ahead!

The SFI is predicted to fall next week, perhaps to the 180s or 190s. Meanwhile, HF propagation remains good at times, although we are still feeling the effects of the summer doldrums, with reduced daytime maximum usable frequencies.

Keep an eye on solarham.com for up-to-date geomagnetic information.

The 15m band is still the favoured daytime DX band, with occasional F2-layer openings on the 12m and even 10m bands. However, most 10m openings are still due to Sporadic-E.

And now the VHF and up propagation news from G3YLA and G4BAO

The weather patterns that drive some of our radio propagation conditions are in the process of changing.

As we ended the previous week, there were still regions of high pressure near enough to southern areas for some useful Tropo across the North Sea, English Channel and south over Biscay.

The slow change towards low pressure dominating the charts will be gradually extending its influence over the whole country as we move into next week, so less Tropo and more interest in rain scatter.

This has been available over some northern areas recently and from heavy thunderstorms in the south. It is probably going to be a useful mode for exploring the GHz bands in the coming week, particularly where heavy thundery rain occurs.

Meteor scatter is also a worthwhile pursuit since we are still in the broad period of the Delta Aquariids meteor shower and that eventually blends into the August Perseids later in the month.

The solar conditions continue to be challenging and the Kp index has been high enough to make it worth thinking of checking for auroral conditions – either fluttery signals on the LF bands overnight, or perhaps auroral conditions on the VHF bands. The Kp index gets mentioned on all propagation websites these days, but spaceweather.com is a good source for that and much else too.

Sporadic-E is still worth checking out and, although the summer jet stream pattern is usually pretty weak, it is still there, and the position is perhaps a bit more northerly now than earlier in the summer. This means that paths towards the east to Scandinavia and the Baltic might be worth looking for, although other directions can still happen, of course.

Moon declination started to fall from Friday the 2nd, so Moon window lengths and peak Moon elevation will follow suit. With apogee on Thursday the 8th, path losses will be at their highest for the month. 144MHz sky noise is low until the evening of Saturday the 3rd when we see the Moon and Sun close in the sky until moonset on Sunday. After that, the sky noise is low.

And that’s all from the propagation team this week.

Sunday the 28th of July 2024

The news headlines:

• Two new Directors have been co-opted to the RSGB Board
• The RSGB welcomes two new Regional Representatives
• The RSGB National Radio Centre is looking for volunteers

When Paul Nichols, M0PVN resigned as an RSGB Director in May, it created a vacancy on the Board. The Board decided that it was in the Society's interests to expand the Board to nine people to help implement the Society’s strategic priorities. Under Article 37 it has co-opted Peter Bowyer, G4MJS and Peter Ransom, M0SFZ as Directors to serve until the 2025 AGM. Peter Ransom recently passed his Full licence so that he could build and tinker with RF equipment, to add to his ongoing interest in writing amateur radio software and designing his own PCBs. He has a passion for technology and communication and has had a career that combines technical expertise with strategic vision. He hopes to use that knowledge and experience to help the Board to ensure that the Society remains relevant to the amateur radio community. Peter Bowyer has been in and around IT all his career and currently helps organisations with their Agile development strategies. He has been licensed for 45 years, but says he is still learning new things. He's an avid contester, having served on the VHF Contests Committee, he has written a column for RadCom and is a past chair of the UK Six Metre Group. The RSGB welcomes them both to the Board.

The RSGB is delighted to announce the co-option of two Regional Representatives. Peter Lowrie, MI5JYK is based in Region 8 and Brian Woolnough, M5ADQ in Region 12. They will serve in these roles until the RSGB 2025 AGM. You can see contact details for either of them, or any member of the Regional Team, on the RSGB website at rsgb.org/regions

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 25th of July 2024

We had yet another week of high sunspot numbers and low geomagnetic disturbances, but will it last?

We dodged a bullet last week after a weak coronal mass ejection, or CME, on Tuesday the 23rd failed to generate a geomagnetic storm. This was from a faint halo CME observed on Sunday, which was much weaker than expected when it hit Earth.

A further M2.4 flare, near the eastern limb on Tuesday, produced a coronal mass ejection, but that was directed away from Earth.

So, we ended the week with a Kp index that never rose above 2, despite up to 19 M-class solar flares occurring. Our luck must run out some time!

The main HF DX this week has been the K8R DXpedition on American Samoa. This has been workable on all bands from 20 to 10m, especially using FT8. They have been trialling a new Super Fox mode on FT8. If you are interested in using this mode, you will need the latest version of the WSJT-X software.

Daylight maximum usable frequencies, or MUFs, over a 3,000km path have reached more than 24MHz, with 28MHz available at times on some paths. This will, no doubt, improve as we head towards the autumn.

Nighttime MUFs over a similar path length have exceeded 14MHz and often reached 18MHz at times. Make the most of the nighttime openings as they will die off as we head towards the end of the summer.

Next week, NOAA predicts the solar flux index will be in the range of 165 to 175 and the Kp index will be a maximum of 2 all week. As ever, this will be dependent on any solar flares and associated CMEs. A CME could easily push the Kp index up and the MUF down.

Four sunspot groups have just rotated into view so keep a close eye on them on solarham.com At least one is classed as “growing” and could be a contender for trouble over the next week by way of solar flares and CMEs.

And now the VHF and up propagation news from G3YLA and G4BAO

The area of high pressure which develops over this weekend will bring the prospect of Tropo conditions at the start of the new week.

The high will drift slowly east towards Denmark by midweek but could still provide the chance of Tropo conditions across the North Sea until Wednesday.

Meanwhile, a weather front will reach northwest Scotland on Monday and edge slowly south whilst a small thundery low develops near the southwest of Britain. This combination will bring a gradual transition to more unsettled weather with a chance of rain scatter on the GHz bands for the second half of the week.

The Delta Aquariid meteor shower is active from the 12th of July to the 23rd of August. With no noticeable peak, it is expected to reach its maximum rate of 25 per hour on or around the 30th of July.

We should have more than just random meteors to use for meteor scatter operation, so it's worth trying meteor scatter on the VHF bands. Also, given clear skies and darkness over the next few weeks, it's worth having a look out for them with the naked eye or photographically.

This extra input of meteors may well improve the prospects for Sporadic-E, which have perhaps seemed a little less than enthusiastic recently. Meteor debris from meteor showers, or random meteors, provides the fuel for Sporadic-E. These ionised trails in the E region above 100km can be affected by wave motion caused by jet streams much lower down at around 10km.

Fortunately, there are a number of useful jet streams on the forecast charts for next week with a slight preference for paths to Scandinavia and eastern Europe.

Moon declination is positive and rising, reaching maximum on Thursday the 1st of August, so Moon windows are long with high peak Moon elevation. We passed perigee on the 24th so path losses are on the increase. 144MHz sky noise is low to moderate all week.

And that’s all from the propagation team this week.

On Sunday the 28th, the UK Microwave Group 5.7 and 10GHz Contest runs from 0600 to 1800UTC. Using all modes on 5.7 and 10GHz frequencies, the exchange is signal report, serial number and locator.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 18th of July 2024

We had another great week in terms of HF propagation. The solar flux index was at a remarkable 224 on Thursday the 18th, and the Kp index had been consistently in the ones and twos all week.

It doesn’t get much better than this, HF-wise, although it's a shame it's not autumn with the associated good HF autumnal propagation.

Given that we are in the summer HF doldrums, there has been a lot of DX on the bands. 15m has been very good during late afternoons, and open to all continents, with Australia, Asia, Africa, North America and South America all workable on FT8 at the same time.

On Thursday the 18th, there were 17 active sunspot regions visible, which contributed to the high solar flux index. Two X-class solar flares brought short-term solar fadeouts on the 14th and the 16th, but any associated coronal mass ejection has been mainly directed away from Earth.

For those new to HF propagation, this is good news. Remember, a high solar flux index is generally good, while a high, perhaps more than four, Kp index is generally bad.

Daytime maximum usable frequencies, or MUFs, over a 3,000km path have been consistently above 21MHz. Nighttime MUFs have been more than 14MHz, and often 18MHz, at times.

But will this continue? Probably not.

Of the 17 visible sunspot groups, six are classed as ‘growing’. There have been coronal mass ejections from sunspots on the edge of the Sun, but they have not been Earth-directed. But, as these spots rotate to be Earth-facing, a coronal mass ejection could be more problematic.

Next week, NOAA predicts that the solar flux index may fall, perhaps into the 170s to 180s range.

The Kp index is predicted to be around 2, but if we do have an Earth-facing coronal mass ejection that could easily climb to 4 or 5, with an associated drop in the maximum usable frequency.

So, will it be another week without a high Kp index? Maybe that is too much to hope for!

And now the VHF and up propagation news from G3YLA and G4BAO

Last week ended with a decaying high over Germany and fronts pushing in across western Britain. With such warm air over the UK at first, even temporarily, there will be a reasonable chance of Tropo over nearby cooler waters around our coasts, especially along the English Channel and southern North Sea.

Incidentally, for anyone taking a VHF rig with them on holiday to the Mediterranean resorts, you can expect typical summer semi-permanent, very strong maritime Tropo ducts over any sea path to neighbouring islands or countries.

Returning to the UK, we have a series of fronts and lows lined up for the coming week. In summer months these can often have a showery element to them, so expect some heavy rain and thunder at times, but at least there'll be rain scatter to make up for it!

Meteor scatter is again a random experience, with no major showers this week. Try around, or just before, dawn for best results. The solar conditions have been all over the place with flares and weak auroral responses, but nothing dramatic for VHF radio.

Sporadic-E, on the other hand, has done fairly well for digital mode activity, especially for transatlantic paths, but is slightly subdued where higher signal levels are required for SSB and CW. Although the weather is expected to be unsettled, the jet stream activity is less widespread than recently. If anything, the western side of Europe seems in a better spot with quite good options for paths to Iberia. Remember, most years will see activity into the first week of September, so don’t give up yet.

The Moon is at minimum declination on Friday the 19th so we start the week with short Moon windows and falling path losses as we approach perigee on the 24th. Perigee is the point at which the Moon is closest to the Earth. 144MHz sky noise starts very high but declines to medium next week.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 11th of July 2024

We had another week of reasonably settled geomagnetic conditions and a high solar flux index.

The solar flux index was at 214 on Thursday the 11th, while the Kp index has been around 2 to 3 all week. That’s generally good news for HF.

However, a small coronal hole is now facing Earth and a solar wind stream flowing from this zone was predicted to reach Earth by the 13th of July. This could result in an elevated Kp index and lower maximum useable frequencies, or MUFs for short. It probably won’t last too long, so expect conditions to be back to normal by tomorrow, the 15th.

Active region 3738 is dominating the Sun’s surface but has only been the source of minor C-class solar flares and will remain a threat for moderate M-class flares. All other regions have been mostly stable.

The daytime MUF over a 3,000km path has often exceeded 24.9MHz, with some better-equipped stations reporting contacts into Australasia on the 10m band.

Night-time MUFs over a similar distance are still consistently above 14MHz. Make the most of this as they are likely to drop as we head out of summer and into autumnal conditions.

The MUF is extrapolated from the Dourbes ionosonde data and should only be used as a guide – it may often be higher, especially in some directions.

The most sought-after DX this week has been K8K/K8R in American Samoa. The DXpedition is testing out all systems on all bands, using CW, SSB and FT8, ahead of the upcoming Jarvis Island DXpedition. The station has been worked from the UK on the 30 to 10m bands, mainly by well-equipped stations, and has been testing the FT8 Superfox mode with some success.

Otherwise, contestants in the RSGB’s 80m SSB Club Championship on Wednesday the 10th reported fair conditions, but a very, very noisy band. Noise is often a limiting factor, especially on the lower HF bands.

Next week, NOAA predicts that the solar flux index may decline to the 180 to 190 range. Geomagnetic conditions may be unsettled today, the 14th, with a Kp index of 4 at times. The second half of the coming week should be more settled, as long as we don’t have a coronal mass ejection.

And now the VHF and up propagation news from G3YLA and G4BAO

The overall picture is of unsettled weather still being around for the coming week, but there will be some temporary moments of weak high pressure to alleviate incessant rain.

As we end the current week, pressure will rise over western areas bringing a chance of Tropo for paths down the Irish Sea and across Biscay. There will also be a second period of high pressure for a time in the middle of next week, favouring the south. This gives us at least a chance of Tropo for this week’s UK Activity Contests on the 23cm and 4m bands.

The ‘unsettled’ part of the story is worth noting, especially if we get some heavy thundery downpours, which should be great for rain scatter. Continuing with scatter modes, there is always meteor scatter as a diversion and the advice is to look in the early hours before daybreak when random meteors are more likely.

Solar conditions are still not entirely settled so there remains a chance of aurora should the Kp index rise to 5 or more. The Sporadic-E season is still doing good business within Europe, but it feels as though it’s not been quite so noticeable as during June for UK stations.

The jet stream pattern is trying to help next week with several useful segments over northwest Europe, which should improve the chances of Sporadic-E paths from the UK into the continent.

Moon declination went negative again on Friday the 12th, which also corresponds to apogee, the point at which the Moon is furthest from Earth. So, Moon peak elevation and path losses will continue to fall again next week. 144MHz sky noise starts low early next week rising to a high of 2100 Kelvin on Friday.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 4th of July 2024

After a rough spot last weekend, the Sun has since behaved itself, allowing HF propagation to get back to normal. To recap, the Kp index hit 7.67 on Friday the 28th of June, thanks to incoming plasma from a coronal mass ejection. For a time, it looked like we might have a repeat performance of the 10th of May when the Kp index hit 9 and there was a visible aurora across the UK.

This time around, however, conditions calmed down again and 24 hours later the Kp index was back to 2.33. Since then, the Sun has remained calm with only two M-class and zero X-class flares, and the Kp index is back in the 1 to 3 range.

This means that the ionosphere has had a chance to build up and we have been seeing MUFs over a 3,000km path exceeding 21MHz and often reaching 24MHz. That’s pretty good considering we are in the Summer HF doldrums.

An analysis of the Sun's active sunspot regions shows that two are growing, five are declining and one is stable.

WSPRNet.org shows that signals have been getting to the UK from Australia, New Zealand, Japan and the Far East on the 15m band, while 28MHz is still mainly open to short-hop Sporadic-E contacts across Europe.

The solar flux index has declined over the past week and was sitting at 167 on Thursday the 4th of July. Next week, NOAA predicts it will remain around the 170 mark, with quiet geomagnetic conditions.

However, solar flares and coronal mass ejections remain hard to predict so keep an eye on Solarham.com and Propquest.co.uk for a real-time view of solar and geomagnetic conditions.

And now the VHF and up propagation news from G3YLA and G4BAO

The weather sequence to the end of next week is much like an autumn pattern in that the story is all about areas of low pressure, showers and weather fronts. None of this suggests that Tropo will be a feature of the weather. In fact, high-pressure systems simply do not appear on the charts at all.

We can leave rain scatter on the list and, since it is technically summer, or meant to be, there is a lot of energy in any showers. Indeed, some may be heavy and thundery and are probably good rain-scatter candidates. Meteor scatter, in the absence of major showers, is most likely around the dawn period when random meteors tend to be more prevalent.

The solar conditions continue to offer much variability and it is always worth checking for elevated Kp index values, which can be a signal for aurora to occur. As a general guide check the bands when Kp reaches 5 or higher.

The Sporadic-E season continues, although recently there have been some higher-than-ideal Kp indices, which unlike for aurora need to be at lower values, say below a Kp index of 3, for ideal Sporadic-E conditions.

The other ingredient that tends to promote Sporadic-E is the presence of jet streams in the upper atmosphere around 10 to 15km up. It is believed that these can generate atmospheric gravity waves that can propagate up to the E region at 110km where they become part of the process for making Sporadic-E.

This unsettled autumn-like weather is providing plenty of jet streams, so it continues to be worth checking for Sporadic-E. A quick look at the upper air pattern suggests that paths towards Scandinavia and the Baltic may be productive, and perhaps to Iberia later next week.

Moon declination is close to maximum positive this coming weekend so Moon peak elevation will be high. Moon apogee is on Friday the 12th so EME path losses continue to increase. 144MHz sky noise is low all week.

And that’s all from the propagation team this week.

Sunday the 30th of June 2024

The news headlines:

• The IARU HF Championship is coming up
• Learn about the QMX+ transceiver at the next RSGB Tonight@8 webinar
• The Examinations Standards Committee has published its annual report

The IARU HF Championship contest will be held between the 13th and 14th of July and there is a great opportunity for you to get involved in a different way this year. During the contest, ‘Headquarters Stations’ represent their countries and the RSGB’s station GR2HQ will be run by a network of about a dozen stations around the UK and islands. This year, the RSGB Contest Committee has introduced a new challenge to encourage individual stations to work the GR2HQ station on each band-mode slot. You will be able to submit your log, including QSOs with GR2HQ, to the RSGB contest robot for the GR2HQ Challenge. If you include your club or group name when you submit your log, each QSO with GR2HQ will count towards an aggregate score for your club or team. There will be two results tables, one for individuals taking part and one for clubs, so your QSOs can contribute to both! Why not encourage your club members to take part in this special challenge whether they are regular contesters or not. By contacting the GR2HQ station you’ll also help the RSGB’s position in the contest – last year the RSGB came third and the Society would love to improve on that result. You can read more in the June RadCom feature on the GR2HQ Challenge and you can see the rules on the RSGB website at thersgb.org/go/gr2hq

The Examinations Standards Committee has published its annual report, relating to activities in 2023. Whilst the report shows that in 2023 there were fewer candidates across all licence levels, the number of people taking exams so far in 2024 has increased significantly. Another item in the report relates to the preparations that are being made to release the bank of questions for the Full licence exam. The ESC Chair, Tony Kent, G8PBH says that it has long been recognised that a review of the question bank, particularly at Full level, is well overdue and has been delayed multiple times by things such as the need to revise the syllabus for EMF and the new licence changes. Reviewing the question bank is the next priority of the ESC and the Exams and Syllabus Review Group and will begin on the 1st of September when Syllabus 1.6 is up and running. The ESC and ESRG believe it is better that this review is conducted before the bank is published as this should reduce the workload on the community and the exams teams in making and responding to queries on questions that may be withdrawn. They are hoping to release the questions in January 2025. To see the full ESC report go to rsgb.org/esc and click on the minutes, papers and reports tab on the right.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 27th of June 2024

We had another lucky week with quite a high solar flux index, low Kp geomagnetic numbers, few solar flares and no coronal mass ejections, or CMEs, of note. In fact, you couldn’t ask for better!

But is that all about to change? With nine active solar regions on the Sun’s surface and the return of old region 3664, now renamed 3723, it would be a brave person to suggest otherwise.

So, let’s take a closer look at the Sun. Of the nine active regions that are visible, four are classed as stable, one is classed as declining and four are classed as growing.

With a solar flux index of 181, there is plenty of UV radiation around. However, we are currently in the summer doldrums so maximum useable frequencies, or MUFs, are lower than they are in the Autumn and Winter. In other words, we are not going to see a return to reliable worldwide DX conditions on the higher bands until mid to late September.

There is currently only a 5% chance of a strong X-class solar flare, although a bright coronal mass ejection was observed for a second day off the Sun’s west limb. This was directed away from our planet so shouldn’t affect us.

NOAA predicts that the Kp index could rise due to CME arrivals from an event that left the Sun on the 24th of June. Expect a Kp of 4 or 5, with a reduction in the MUF until the geomagnetic disruption abates. It also predicts that the solar flux index will remain in the region of 190, hopefully with a low Kp index after the ionosphere settles again.

MUFs over a 3,000km path are generally between 18 and 23MHz during daylight and around 18MHz at night. This means that for the next month or so we may expect 14MHz to remain open throughout the night.

And now the VHF and up propagation news from G3YLA and G4BAO

The current week finishes with a return to unsettled weather and cooler air, after a brief taste of summer, particularly in the south of Britain.

There will be lows drifting in from the Atlantic during the coming week, as well as the occasional passing weather front. Although there was some Tropo last week, during the brief period of high pressure, this is unlikely to be repeated in the coming week.

Therefore, we have a continuing random chance of some rain scatter, but you will need one of the many online weather radar displays to track the scatter regions down. Since next week also looks windier, you might have to keep one hand on the rotator!

Meteor scatter is once again down to random events, which means an early start in the shack to capture the higher rates in the early mornings.

The solar conditions continue to keep trying to creep into VHF affairs with a higher Kp index and thoughts of radio aurora, but it's probably not a strong shout.

Now to our last item – Sporadic-E. There is still the broad summer Sporadic-E peak, which extends into the first week of September in a good year, so you have plenty of time. It will not always be there but, in a test analysis of Dourbes data in June 2022, 84% of the days reached 10m, with 18% up to 6m and around 10% to 4m or above. This makes it worth using the 10m band to highlight the regions of activity and then check the 6m beacons in case it strengthens to bring in the higher bands.

Moon declination goes positive again this coming weekend so Moon peak elevation and window lengths will increase. Perigee was on Thursday the 27th so EME path losses are increasing again. 144MHz sky noise is low at the start of the coming week and moderate later. From Friday afternoon on the 5th of July to midday on Saturday, the Moon and the Sun are very close in the sky, meaning high noise for all but the narrowest beamwidth antennas.

And that’s all from the propagation team this week.

GB2RS News

Sunday the 23rd of June 2024

The news headlines:

• RSGB Convention workshops and practical sessions – what would you like?
• RSGB Team interviewed by ICQ Podcast at the Dayton Hamvention in May
• Don’t forget to try the updated RSGB Discovery Scheme

Do you like making things? Are you interested in finding out more about the Raspberry Pi or programming an Arduino? Have you heard about the NanoVNA and DragonOS but don’t know where to start? The RSGB wants its 2024 Convention to offer practical sessions to help radio amateurs try something new, develop their skills and go away inspired! If you can offer to run a workshop or a practical session over the weekend of the 11th to the 13th of October, or you’d like to take part in one, please email the RSGB Convention Team via convention@rsgb.org.uk by the 3rd of July. As part of its strategy, the RSGB wants to ensure that this prestigious annual event not only meets the needs of its members but also helps every radio amateur to share their love of the hobby with others.

Members of the RSGB Team, including RSGB President John McCullagh, GI4BWM and RSGB General Manager Steve Thomas, M1ACB, had a successful time at the Dayton Hamvention in May. The event was a brilliant opportunity to engage with radio amateurs from around the world and it resulted in 132 people joining the RSGB. It also provided several media opportunities with podcasters, YouTubers and local news outlets. Martin Butler, M1MRB from ICQ Podcast was one of those who interviewed the President and the General Manager. The interview covered a wide range of topics, from using the new licence conditions as part of outreach, to the RSGB’s role in defending the spectrum and even to the RSGB President’s amateur radio activities with both RAYNET UK and SOTA! For the full interview go to Episode 432 on icqpodcast.com and listen just before two hours into the episode.

Have you tried the updated RSGB Discovery Scheme? Now called the Discovery Logbook, there are fewer requirements, an easy-to-follow programme and exciting links with external organisations such as Parks On The Air and Worked All Britain. There are also some great RSGB Awards to work towards if you’d like to include those in your programme of activities. As a relatively new radio amateur, Jim, ME7HEF had found that the sheer breadth of the hobby made it a little difficult to know where to start. The Discovery Scheme gave him a simple structure to try various aspects of amateur radio and he has enjoyed it. Read more about Jim’s experience on the RSGB website at rsgb.org/your-stories and follow the links to find out how you could try something new using the Discovery Logbook.

The RSGB is looking for an individual to take on the complex role of Editor of the annual RSGB Yearbook, following the retirement of the previous Editor. This is a paid post, working part-time from home for a few months each year, and is offered as a fixed-term contract. You will need experience of editing material from a wide range of sources and working to deadlines, as well as having attention to detail. An understanding of desktop publishing programs such as InDesign will be helpful along with knowledge of the breadth of amateur radio in the UK today. If you are interested in this post, please email authors@rsgb.org.uk with an appropriate CV or covering statement of your abilities.

Last weekend was 1940s weekend at the Bletchley Park Museum. The RSGB National Radio Centre, or NRC, supported the event by hosting the World War Two Special Operations Executive radio station, GB1SOE. The station, operating on the 40m band, attracted lots of visitor attention, as did GB3RS which was busy on the air as part of the Museums on the Air weekend. NRC volunteers made QSOs and invited visitors to pass greetings messages. If appropriate, the volunteers used the new licence conditions to allow visitors to run QSOs themselves under supervision. The weekend was a huge success and 1,211 people visited the RSGB National Radio Centre. The Society would like to thank all the NRC volunteers who delivered such an enjoyable weekend.

Alexanderson Day will take place on Sunday the 30th of June 2024. The unique Alexanderson alternator, with the callsign SAQ, is scheduled for two transmissions on 17.2kHz using CW. At 0830UTC, the alternator will be started up and at 0900UTC the first transmission will take place. A second transmission is scheduled for 1200UTC. You can read more about the event and historic transmitter at alexander.n.se

The Bath Based Distance Learning team is busy enrolling students into its pre-course classroom for its forthcoming course for the Full Licence exam. The team has received enquiries about whether its course is suitable for the Direct to Full exam. The course content focuses on the Full level syllabus items, which are only a part of the Direct to Full syllabus. Learners are expected to know the Foundation and Intermediate material already. Parallel study is possible, but the Bath Based Distance Learning Full Licence course alone would not be sufficient to ensure a pass in a Direct to Full exam. More details can be found in the latest edition of RadCom, but please note that the email address provided to RadCom was incorrect; anyone wanting details of the Bath Based Distance Learning course should email Steve, G0FUW, using g0fuw@bbdl.org.uk

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 20th of June 2024

We had a relatively quiet week, with the Sun generally being settled. There were coronal mass ejections, but they were on the far side of the Sun and not Earth-directed.

There were no X-class flares, although we did have a few C- and M-class events.

The solar flux index declined to 167 but has since recovered and stood at 196 on Thursday the 20th. Active regions 3712, 3713 and 3716 are all large and 3712 has been emitting flares. However, all three regions will soon rotate out of view, so should not be a threat in the coming week.

As such, HF conditions have been reasonable given the time of year. Maximum usable frequencies over a 3,000km path during daylight have generally been between 14 and 21MHz, although there have been occasional openings up to 24MHz. Sporadic-E remains the main propagation mode on the 10m band.

Next week NOAA predicts that the solar flux index will remain in the 175 to 190 range and geomagnetic conditions are predicted to be mainly settled.

However, the far-side coronal mass ejections we have been seeing suggest we could be in for a rough ride in about a week to ten days. So, this week could be a good time for HF propagation.

And now the VHF and up propagation news from G3YLA and G4BAO

The weather is trying to change to a more summer-like pattern, which means that the main jet stream will be farther north than recently and this will make Sporadic-E harder to find than during the recent strong jet stream pattern over Europe.

For most UK stations, the emphasis on Sporadic-E paths will gradually shift from the typical central Europe and Mediterranean to perhaps Scandinavia and the Baltic states.

The relatively new player this time around will be high pressure which comes and goes during the period but should bring some useful Tropo. In these high-summer days, sea or coastal paths are often good, but paths across hot land do not fare well in summer during the daytime. Concentrate on the night or early morning, especially if it is foggy.

There will be occasions when small lows and fronts edge into the south and west of the British Isles and, in typical summer fashion, may bring a risk of thundery showers. Any local, heavy rain means good conditions for rain scatter on the GHz bands. Meteor scatter again remains in the random category, which usually peaks around the dawn period.

Lastly, a note about aurora which has been kept at arm’s length although there have been several periods with a slightly enhanced Kp index. The light summer nights mean that visible auroras are very unlikely but do look out for noctilucent clouds on the northern horizon around midnight.

Noctilucent clouds are thin, wispy clouds that glow with a blue or silvery hue at night when illuminated by sunlight from below the horizon.

The Moon is at minimum declination this coming weekend so peak elevation is low and windows of usage are short. EME path loss is falling as we approach perigee next Thursday the 27th. 144MHz sky noise is high this weekend but falls to low early next week.

And that’s all from the propagation team this week.

On Sunday the 23rd, the 50MHz CW Contest runs from 0900 to 1200UTC. Using CW on the 6m band, the exchange is signal report, serial number and locator.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 13th of June 2024

No sooner do we say that conditions will remain good than the Sun emits an X-class solar flare! Such is the challenge of writing propagation predictions.

Nevertheless, after the X1.5-class flare on the 10th of June, things settled again and, at the moment, there are no incoming coronal mass ejections, or CMEs for short, to report. With a Kp index of less than 1 on Thursday the 13th, and a solar flux index of 165, it looks like HF conditions could be quite good.

However, the Sun’s proton flux has increased and is close to the 10 million electron volts warning threshold. This means that paths through the polar regions might be disrupted. Protons can herald the arrival of a CME two or three days later, although NOAA is not predicting any disruption.

On the 13th of June, the critical frequency was between 7 and 8MHz, meaning a maximum useable frequency over a 3,000km path of around 21 to 24MHz. The 10m band will be open, mainly to Sporadic-E. However, F2-layer propagation on the 10m band will be sparse.

NOAA predicts the solar flux index will fall to around 155 today, the 16th, before climbing again to around 195 in a week. Geomagnetic conditions are predicted to be quiet all week, but that may be because solar flares and CMEs are hard to predict at this point in the solar cycle.

As always, make hay on the HF bands while the Sun shines! And make the most of the Sporadic-E propagation on the higher HF bands as June is probably a peak month for this.

Finally, the latest sunspot data show that the average sunspot number for May was 171.7, the highest in 22 years. However, the ARRL reports that shortwave conditions were above average on only six days out of the entire month of May, and mostly poor on half of the days due to geomagnetic disturbances and solar flares.

And now the VHF and up propagation news from G3YLA and G4BAO

The current spell of seemingly endless, poor weather is struggling to provide much Tropo. The general theme is low pressure bringing weather fronts with rain or, if not that, then scattered heavy showers.

This again points to rain scatter for the GHz Bands as the mode worth exploring. There is just one glimmer of Tropo hope in that the latest model predictions are starting to inject the notion of a ridge developing over southern areas, initially around mid-week but perhaps more so at the end of the week. Although, it's fair to say that other models hang on to the low-pressure theme. That said, it's worth checking from the middle of next week onwards.

There are no significant meteor showers this week so continue to check for random meteors around dawn.

The solar conditions have continued to trickle charge the auroral oval with an occasionally enhanced Kp index indicating possible aurora. This is unlikely to be visible at this time of the year although, if you are outside with a clear view to the north, you might be rewarded with a seasonal look at noctilucent clouds to make up for it.

High-summer Sporadic-E propagation is providing daily contacts so it’s worth checking the bands each day. The daily blogs always have something to show on the 10m band and many days there are reports of contacts on the 6m band. Remember these openings are not always reachable from all parts of the UK. One of the characteristics of Sporadic-E is that at each end of the path the ‘signal footprint’ is very small. Even in a busy opening, signals may still pass you by but you should continue to monitor in case a Sporadic-E path opens up that does include your station at one end!

Moon declination is negative again from this weekend, ending today the 16th. EME path loss was at its highest at apogee on Friday the 14th. 144MHz sky noise starts the week low but rises steadily, reaching over 3,000 Kelvin on Friday the 21st.

And that’s all from the propagation team this week.

The news headlines:

• TX Factor is marking its tenth anniversary by launching its 30th episode
• Changes to the four-year planning rule in England
• Bath Based Distance Learning’s next Full licence course is starting soon

TX Factor is marking its tenth anniversary by launching its 30th episode. It looks at how radio technology has advanced since Marconi conducted some of his early transmissions. The episode includes the first of a two-part feature on operating via the QO-100 geostationary satellite with a look at the hardware and software needed to achieve your first QSO at home or out mobile. Bob, G0FGX reviews the FTM-500D which is the latest mobile transceiver from Yaesu and demonstrates the many advanced features of this versatile FM and digital rig. There is a visit to Sidmouth Amateur Radio Society which secured a derelict former sports social club from the local council and turned it into a community hub and the club’s new QTH. Watch this interesting episode and don’t miss out on the TX Factor free-to-enter draw with a chance to win three RSGB publications. You can see this and previous episodes on txfactor.co.uk

The four-year planning rule has offered a degree of protection for antennas and masts that have been erected without planning permission. Under this rule any installations which had been installed and unchanged for four years or more were protected against planning enforcement action. However, as of the 25th of April 2024, this rule ceased to exist in its current form in England under changes introduced under the Levelling-up and Regeneration Act 2023. The rule has been replaced by a more stringent ten-year period for the exemption from enforcement for residential dwellings. This change does not affect Wales, Scotland and Northern Ireland where the four-year rule will continue to apply. Any installation that was substantially completed before the introduction of the Act will still be subject to the four-year rule meaning, for most radio amateurs, the ten-year rule will not apply until the 24th of April 2028. For more information on planning matters visit rsgb.org/planning

Bath Based Distance Learning’s next Full licence course runs from August to December, with exams in January. There is no charge for the training, but applicants must work through some pre-course material and complete a quiz to be eligible for a place. To request full details, and an application form, please email Bath Based Distance Learning’s Team Leader, Steve, G0FUW via g0fuw@bbdl.org.uk

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 6th of June 2024

It seems that we haven’t had a repeat performance of the auroral conditions caused by active sunspot region 3697. For Aurora watchers, that could be a disappointment, but for HF lovers it means the bands have been quite settled.

The Kp index has been at 3 and below, while the solar flux index has been consistently above 175 all week. As a result, HF conditions have been quite good with maximum usable frequencies over a 3,000km path being regularly over 21MHz and often 24MHz.

It is always a good idea to operate on the highest HF band that is open as absorption decreases the higher you go.

Meanwhile, Sporadic-E propagation brought interest to the 10m band with stations from all over Europe being workable for long periods, but more of that in the VHF report.

On the 5th of June, a filament located in the northeast quadrant erupted. The event flung a coronal mass ejection into space that doesn’t appear to be Earth-directed. But this shows that we are still in the danger zone for major solar events, and anything could happen.

Next week, NOAA predicts that the solar flux index will remain around 175, but we expect some geomagnetic disruption today, the 9th of June, with a predicted Kp index of 4. Otherwise, solar conditions are predicted to be calm next week.

So, if these conditions continue, this is a good time to make the most of the HF bands.

And now the VHF and up propagation news from G3YLA and G4BAO

The weather pattern for the coming week is dominated by low pressure, which means there is unlikely to be any significant Tropo to speak of.

There will probably be several opportunities for those on the GHz bands to search for rain scatter. However, these events look to be moving showers or rain bands, which means that you’ll need to be pretty agile with the rotator to keep on the scattering target.

With the solar conditions continuing to keep the pot simmering it's not impossible that the Kp index could rise high enough to promote an aurora, but it's a low probability.

The early part of June is well regarded for minor meteor events and should be worth a look for those using meteor scatter modes.

There were several Sporadic-E openings early in the week that finish today, the 9th. Sporadic-E was reported up to the 2m band on a few occasions. Last Sunday, the 2nd, lasted up to three hours on the path from Eastern England down to the Italian peninsula.

Events initially get picked up on the 10m band and then move up through the VHF bands of 6m, 4m and finally 2m as the Sporadic-E propagation strengthens. In this peak of the Sporadic-E season, the openings on the lower bands, such as 10 and 6m, can be present for much of the day and certainly quite late into the evening.

Follow the weather patterns on the daily Sporadic-E blog on propquest.co.uk and you should be able to point in the right direction for an opening. Multi-hop paths to the Far East or the Americas require a good antenna like a beam, but single-hop European Sporadic-E propagation can be very strong, and any antenna will do the job.

Moon declination is at its maximum this weekend for the DUBUS 10 and 24GHz EME contest, but EME path loss is rising. 144MHz sky noise is low all week.

And that’s all from the propagation team this week.

The RSGB Board recently spent an afternoon visiting RSGB Headquarters, meeting staff and gaining a more detailed understanding of the work of this professional team. Later that day, the Board received training from members of the senior team about their specialist areas. During the Board meeting the following day, the Board decided to continue with its chosen four strategic priorities until the 2025 AGM. These priorities are the growth of amateur radio; membership of the RSGB; spectrum and licensing; and ensuring the continued financial stability of the Society. To make further progress with the outcomes of the recent growth workshop, the Board allocated a member of its team to champion each of the seven workstreams. Each workstream champion will now create a volunteer team, prioritise work tasks, set measurable objectives, define what success looks like, list deliverables and establish reporting mechanisms and frequency. More details will be shared about these over the coming months.

Do you have some spare time to support fellow radio amateurs? Are you passionate about the future of amateur radio? Do you like a challenge?

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 30th of May 2024

Last week was characterised by relatively quiet geomagnetic conditions and a fairly high solar flux. But is that all about to change?

Active region 3664 has returned. It is now named 3697 and has already emitted an X1.4-class solar flare. You may recall that it was AR 3664 that caused the aurora that was visible all over the UK around the 10th and 11th of May.

As Solarham.com says, “The chances for an Earth-directed eruption will increase with each passing day as the active sunspot region turns into a better geoeffective position.”

Scientists now believe that the coronal mass ejection associated with the long-duration X1.4-class flare on Wednesday the 29th may pass close enough to Earth to generate moderate G2 geomagnetic storming beginning on the 31st of May – just in time for this weekend’s National Field Day!

Otherwise, HF propagation has generally been good with decent F2-layer openings up to 21 and even 24MHz at times.

The 17 and 15m bands look to provide the best DX, with paths to the east in the morning, and to the west during late afternoon and early evening.

The 10m band is subject to Sporadic-E openings, with F2-layer openings mainly restricted to paths to South Africa and South America.

Next week, NOAA predicts that the solar flux index will be in the 165 to 200 range, with quiet geomagnetic conditions. However, that is perhaps a little optimistic as active region 3697, or perhaps 3691, could easily throw a spanner in the works, with a flare and associated CME potentially sending the Kp index skywards.

So, as always, keep an eye on the current state of the Sun at solarham.com, and work the bands while they are open!

And now the VHF and up propagation news from G3YLA and G4BAO

The close of the current week offers a temporary return of high pressure for this weekend. This should be good for some Tropo conditions for western parts of the UK. The weather turns a bit more unsettled going through the coming week, especially over northern Britain, but also occasionally in the south.

Rain at this time of the year can often be heavy and thundery with good prospects for GHz bands rain scatter, but this may have to wait for the end of next week when a low moves north from France towards the southern UK.

The early part of June is a time of several minor meteor showers. These should offer scope for meteor scatter operators as well as provide some fuel for Sporadic-E propagation which rocket measurements show consists of long-lived meteor ions.

Sporadic-E propagation is often associated with the position of jet streams in the upper troposphere due to the turbulence that these fast-flowing currents of air generate.

In the coming week, the jet stream pattern becomes much weaker, although still with a few options. Daily blogs are available at Propquest.co.uk for those who are interested.

Don’t ignore the prospects for multi-hop transatlantic paths to the United States and particularly the Caribbean, which are usually well supported in the early part of the season before the upper winds over the Caribbean change over to high-summer slacker flow.

Equally, multi-hop Sporadic-E paths to the Far East are worth checking in the early morning following the effects of the now displaced northerly meandering jet stream flow across northern Russia.

Moon declination went positive again on Saturday the 1st of June, so the coming week will see lengthening Moon windows. EME path loss is falling, reaching a minimum at perigee today, Sunday the 2nd of June. 144MHz sky noise is low apart from Thursday when the Sun and Moon are close in the sky.

And that’s all from the propagation team this week.

The news headlines:

• The RSGB’s Exams and Syllabus Review Group is seeking volunteers
• RSGB representatives had a successful time at Dayton Hamvention
• The RSGB Discovery scheme has just been relaunched in a new format

The Exams and Syllabus Review Group – or ESRG as it is often known – is looking for new members to move the group forward. Its current task is to approve a new Direct to Full syllabus and to write and approve new questions for the new exams in September due to licence changes. The group meets online every Tuesday between 3 pm and 4.30 pm, with members of the Exam Standards Committee, but meeting times can be changed to accommodate everyone. ESRG volunteers need to be Full licence holders, members of the RSGB and be able to give a few hours a week. This is your chance to shape the future as we move to Syllabus 2.0 in 2025. To volunteer or find out more, contact the ESRG Chair Andrew Lenton via esrg.chair@rsgb.org.uk

Members of the RSGB Team, including RSGB General Manager, Steve Thomas M1ACB and the RSGB President, John McCullagh GI4BWM had a successful time at the Dayton Hamvention last weekend. The event was a brilliant opportunity to engage with radio amateurs from around the world and resulted in 132 people joining or rejoining the RSGB. There were also several podcasters, YouTubers and local news outlets in attendance. This included WHIO, which is a local US news channel, who interviewed RSGB President, John McCullagh GI4BWM. This was shared on local TV news, radio, as well as online. Josh from Ham Radio Crash Course also did a live stream to his 346,000 YouTube subscribers, which included a chat with RSGB General Manager, Steve Thomas M1ACB and the RSGB President. You can find links to view these clips on the RSGB notices section of the RSGB website.

The RSGB Discovery scheme has just been relaunched in a new format. Now called the Discovery Logbook, there are fewer requirements, an easy-to-follow programme and exciting links with external organisations such as Parks on the Air and Worked All Britain. There are also some great RSGB Awards to work towards if you’d like to include those in your programme of activities. The RSGB hopes that these links will enable radio amateurs to discover new ways of enjoying their hobby with the guidance and support of experts in those fields. There are three difficulty levels and the first of these, called Explorer, has just been launched. To see the programme activities, find out how to get involved or talk to the Society about linking your organisation with the Discovery Logbook, go to the RSGB website at rsgb.org/discovery

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Wednesday the 22nd of May 2024

After the extremely unsettled HF conditions on the 10th and 11th of May, it was gratifying to see things returning to normal last week.

The Kp index has returned to being in the range of 1 to 4 and, with a solar flux index still in the 190s, we have seen some good propagation around the world.

But make no mistake – it probably won’t last!

Active region 3664, the source of so much mayhem a couple of weeks ago, will soon return from its trip around the Sun. It has probably been the source of a major flare while on the Sun’s far side and there is a good chance we may get a repeat performance of last month.

Meanwhile, make hay while the Sun shines!

NOAA predicts that the solar flux index will increase above 200 next week, but unsettled geomagnetic conditions are forecast for tomorrow, the 27th of May, and at the end of the month and into early June.

Daytime critical frequencies have been between 8 and 9.3MHz, making 40m a good band for inter-G QSOs. These have also meant that the maximum usable frequency over a 3,000km path has often exceeded 24 to 27MHz, making 12m a viable band for DX. Note that this is a little patchy, so if you don’t hear anything on 24MHz just wait a while or check later.

Nighttime critical frequencies are usually around 6 to 7MHz, meaning 20m is generally open all night with occasional openings on 17m.

We are now well into the Sporadic-E season so there should be lots of short-skip into Europe on the 12 and 10m bands to play with.

And now the VHF and up propagation news from G3YLA and G4BAO

The end of the current week, in the lead-up to the bank holiday weekend, shows a low and its thundery rain moving north and leaving behind a slack area of pressure with a weak trend towards building a ridge over the country.

The bulk of next week is showing up with a slack westerly pattern and weak fronts brushing past. From midweek, and towards next weekend, the frontal systems will be more active with longer periods of heavier rain possible.

The end result for most VHF and up operators is that there may be some occasional Tropo events, especially overnight during the slacker period with the weak ridge over the country by the start of the weekend.

A more likely option will again be rain scatter which will produce better scattering from the larger raindrops now the summer season is upon us, and thundery developments are more common. Check the many online weather radars for your tracking beam headings.

Meteor scatter will also be worth considering since we are approaching the period when many lesser showers appear to pep up the background meteor count. This will be useful for meteor scatter operators and serve the Sporadic-E folk well.

The solar activity continues to deliver random events which take the Kp index to high values. Remember that a Kp index greater than 5 indicates the chance of aurora propagation.

The primary mode at this time of the year is Sporadic-E. The late May and early June period is often regarded as a peak time for monitoring your favourite VHF beacons. As many will know, the 10m band is a useful starting point for identifying the beginning of an opening, and then you should check the higher bands in turn as the event strengthens. This is often indicated by the skip distance shortening on the 10m band.

The other basic operating tip is to use the daily blog on the Propquest.co.uk website for commentary on the effectiveness of the various upper air patterns such as jet streams, which can influence the location where Sporadic-E propagation occurs.

There are no major meteor showers this week so, in between the Sporadic-E, look around dawn for the best random meteor prospects.

Saturday the 22nd sees the lowest Moon declination of the month so next week will see some lengthening Moon windows. EME path loss is falling, but we are still over a week from perigee, its closest point to Earth. 144MHz sky noise starts the week high, as it reached over 2500 Kelvin on Saturday the 25th. It is low for the rest of the week.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 16th of May 2024

After last weekend’s auroral spectacular, it was nice to see the Sun calm down a little and the bands get back to normal. But that didn’t last long.

To recap, on Friday the 10th of May the Kp index shot up to 9, due to the effects of a number of coronal mass ejections, while the HF bands closed down in the subsequent geomagnetic storm.

While there was visible aurora across the UK and Europe, HF propagation suffered and didn’t start to recover until the late afternoon on Saturday the 11th.

The main culprit, active region 3664, has now rotated out of view, but that doesn’t mean we are out of the woods just yet.

Solar flares can cause short-term disruption to HF propagation due to their X-rays penetrating deep into the D-region and causing signals to be absorbed. Subsequent coronal mass ejections can cause longer-term degradation of the F2 layer with reduced maximum usable frequencies, noisy bands and auroral conditions.

At the time of writing, the Kp index stood at 6 again so it looks like unsettled geomagnetic conditions are continuing with a moderate G2 geomagnetic storm in progress.

Low to moderate activity is now expected, with a slight chance of further strong-class flares. The regions currently on the visible disc are smaller and simpler, with isolated M-flares possible from these. However, a new active region, now rotating into view, has already emitted an X-class solar flare.

Next week, the United States Air Force predicts that the solar flux index may remain in the 160 to 180 range. HF conditions remain a lottery as they can be badly affected by solar flares and coronal mass ejections.

It is best to keep an eye on solarham.com for updates, and also propquest.co.uk for near real-time reports of the critical and maximum usable frequencies.

And now the VHF and up propagation news from G3YLA and G4BAO

The weather remains on the unsettled side of things with areas of rain and some thunderstorms over the country, especially the south as we end this week. As this report is being read out, high pressure is becoming established over northern and western Britain.

This may eventually take a tenuous hold over the rest of the country during the second half of the coming week and into next weekend, the 25th and 26th.

This high pressure, although fairly weak, may help with some Tropo for those in northern Britain in the 144MHz May Contest and the Backpackers Contest this weekend, ending on the 19th. It may also be helpful to those taking part in the 1.3GHz UK Activity Contest on the 21st. However, the conditions may not be of much use in the south as another low arrives from the continent.

Overall, rain scatter on the GHz bands will probably be worth exploring in the rainy areas again, since some of the showers may be heavy and thundery.

The prospects for Aurora are still worth keeping in mind despite the recent stunning event. Minor non-visible events can still provide a reasonable radio aurora to explore.

The Sporadic-E season continues to develop. And with such unsettled weather, there are plentiful jet streams to act as source regions for turbulence, which can propagate up to the E region where they can generate Sporadic-E.

We are currently at the tail end of the Eta Aquariids meteor shower. A few meteors from this shower will continue to appear, but no major shower is expected this week.

The lowest Moon declination occurs this coming Friday. With the Moon being full on the 23rd, a clear sky should reveal an impressive ‘Flower Moon’.

For EME, path loss will still be relatively high, although the Moon is starting to move back towards its closest point to Earth, or perigee.

144MHz sky noise starts the week low but rises to high on Saturday the 25th.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 9th of May 2024

Disrupted solar conditions continued this week with X-class solar flares aplenty.

Four X-class events on the 8th and 9th of May prompted coronal mass ejections, which could join together to impact the Earth this weekend. We can expect a strong G3 event with the Kp index rising to 6 and the potential for visible aurora in the UK.

It’s hard to be positive about this as HF conditions this weekend, ending today the 12th, are likely to be very disrupted with reduced MUFs and noisy bands.

But do look out for auroral signals, perhaps on the 10m band, and above, and a potential HF band enhancement just as the plasma cloud hits.

The solar flux index hit 227 on Thursday the 9th, which is one of the highest we have had in this cycle. But don’t get carried away as it is forecast to decline.

Meanwhile, conditions have been typical for this time of year, with reduced F-layer propagation on the 10m band, offset by the start of the Sporadic-E season. The lower HF bands are staying open later in the evening, and may even increase to all night on the 20m band, as we head towards June and July.

Next week, NOAA predicts that the solar flux index will drop below 200, but remain at or above 175 all week. After this weekend’s chaotic geomagnetic conditions, we can expect the Kp index to fall to 2, but increase again on the 13th, to perhaps 4.

In the meantime, solar maximum is still predicted to be later this year, although geomagnetic disturbances are likely to increase on the downward part of the cycle. So, buckle up for a rough ride!

And now the VHF and up propagation news from G3YLA and G4BAO

We end the current week with high pressure over the country and some occasional Tropo paths, especially over surrounding waters. The high will decline from the west as we progress through this weekend.

At the time of reading on Sunday, the transition will be all but complete and low pressure will remain in control for much of the coming week. This means periods of rain, heavy showers or thunderstorms and quite windy weather at times. In terms of propagation, a shift to rain scatter is a good choice for those equipped for the GHz bands for the week ahead.

Recent solar activity continues to offer chances of auroras so remember to monitor the Kp index and check for fluttery signals on the HF bands and raspy signals on VHF. The many clusters and band reports should be a good tool for these conditions.

Lastly, the Sporadic-E season is having a few starting twitches. Earlier in the evening of Wednesday the 8th there was a short opening of about an hour to Scandinavia on 6m CW from a patch in the middle of the North Sea. The positions of the jet streams may not entirely suit further openings in the shorter term but, as the low-pressure moves in next week, things could improve for Sporadic-E paths to Iberia and central Mediterranean.

With the Eta Aquariids peak now past, the next big meteor shower isn’t until July with the Delta Aquariids. But before the Delta Aquariids, we can look forward to the Arietiids in late May.

However, the Eta Aquariids will continue to produce the odd ping or burst. Last week there was plenty of evidence of meteors continuing to burn up after the peak. There may still be the odd one during the coming week together with the usual background sporadic meteor returns.

As the Moon starts to decline this week, the distance between the Moon and Earth is also beginning to increase and with it the path loss increases to a maximum on Friday the 17th and Saturday the 18th. However, sky noise will remain low all week. The Moon is favourably placed for daytime operation this week.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 2nd of May 2024

What a strange week we had. With the solar flux index in the 167 range, falling to 130, conditions should have been reasonable. But the Kp index hit 4, and even 5.33, on the evening of Friday the 26th of April, which meant propagation on Saturday the 27th was truly dire.

Stations taking part in International Marconi Day on the 27th found the 40m band only open to long skip in the morning. This was due to the critical frequency being below 5MHz. The predicted MUF over a 3,000km path fluctuated between 15MHz and 19MHz for the whole day, which meant only 14MHz was open reliably. As a result, QSOs were hard to come by and many stations reported that it was slow going with virtually no signals from outside of Europe.

So what happened? Well, it was a combination of factors. The increased Kp index, due to a fast solar wind, took its toll. And we are now moving to a summer ionosphere, where chemical changes make it harder to ionise. This will mean we should see MUFs dropping as the season progresses, at least during the day. Nighttime MUFs will be higher than in winter.

So it may be that the glory days of 28MHz F2-layer propagation are on hold until Autumn, with only short-skip Sporadic-E on the 10m band to keep us entertained.

F2-layer propagation is still available on the higher HF bands, but it may be patchy.

International Marconi Day station GB0CMS in Caister, Norfolk, reported that its 20m signals were picked up by a reverse beacon network skimmer in Utah, despite not working anyone outside of Europe. Meanwhile, on the morning of the 2nd, Laurie, G3UML was quite surprised to work YJ0CA on Vanuatu on the 15m band using SSB. He also worked 3D2CCC on Conway Reef on the 20m band using CW, and JD1BMH in Japan on the 15m band, also using CW.

Next week NOAA predicts the solar flux index will be in the 125 range, rising to 175 as the week progresses. Geomagnetic conditions are dependent on coronal mass ejections. We have had eight M-class solar flares in the past three days, and a Kp index of 5 on Thursday the 2nd, which doesn’t bode well for next week. So, keep an eye on solarham.com for current conditions and look for the best HF propagation if the Kp index is low for a day or two.

And now the VHF and up propagation news from G3YLA and G4BAO

The weather pattern remains very unsettled for the whole period with areas of low pressure edging north across the UK from the continent.

There will be a risk of thundery weather at times with locally heavy rainfall, which will be good for rain scatter on the Gigahertz bands. Tropo looks to be hard to find as we end the current week dominated by low-pressure systems, but there are signs of high pressure returning after mid-week, but only temporarily.

This could produce some Tropo paths, especially across surrounding waters such as the Irish Sea, English Channel and North Sea.

The nominal summer season of Sporadic-E propagation is upon us and, from May to early September, daily blogs will be provided on the Propquest.co.uk website highlighting the possible Sporadic-E links to the position of the jet streams shown on the upper air charts.

It’s well worthwhile getting into the habit of regularly checking the DX clusters and activity maps, since the early season is usually characterised by a complex jet stream pattern with multiple potential locations for Sporadic-E propagation.

Timewise, it eventually settles into a more traditional behaviour with activity often in two phases, one in the morning and the second in late afternoon, early evening.

As you listen to this report, the Eta Aquariids meteor shower should be peaking. Unfortunately, the best viewing for the shower, which is part of the debris from Halley’s comet, will be in the southern hemisphere.

Nevertheless, this is expected to be one of the best showers this century. For those viewing the shower, a waning Moon means that light levels should be low, making for ideal visual sighting.

For EME, the Moon will be waning all week with the new Moon around the 8th of May. The Moon will be rising in the sky throughout the week, with zero declination on the 5th of May and peaking at its highest in the sky on Saturday the 11th of May.

The lowest additional path loss occurs today and tomorrow, the 5th and 6th, but high Sun noise, with the Moon close to the Sun at new Moon, occurs shortly afterwards. Later in the week, as the Sun 'leaves' the Moon behind, noise levels, at least on the higher bands will fall to around normal.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 25th of April 2024

We had another week with plenty of sunspots, and HF conditions were quite good in the second half.

Earlier, the Kp index reached 3 and 4, which didn’t help maximum useable frequencies, or MUFs for short. For example, on Sunday the 21st, the Kp index rose to 4 and the MUF over a 3,000km path remained stubbornly below 21MHz until later in the morning.

This could have been due to a coronal hole on the Sun’s equator, which added to the solar wind. By Wednesday, conditions were nearly back to normal, with a Kp index below 2 and an MUF of more than 24MHz. By Thursday the improvement had continued, giving us an MUF of more than 28MHz by 0900UTC.

There have been many reports of 10m band DX being worked, including Sebastien, FK4AX and Pat, FK8HA in New Caledonia in the Pacific on SSB. Sebastien has just got his licence and is keen to work DX from the UK.

This shows that it is worth keeping an eye on the CW and SSB portions of the 10m band, which can often throw up surprises.

Next week, NOAA predicts that the solar flux index will decline to around 160. The Kp index is predicted to be around 2 to 3, but that may be wishful thinking. With 16 active regions visible on the Sun’s surface on Thursday, anything could happen. Only minor C- and M-class flares have occurred recently but, as we always say, it wouldn’t take much for those to turn into X-class events.

So, make the most of quiet geomagnetic conditions when we have them as, by the time you read or hear this, we could once again have very unsettled conditions indeed.

And now the VHF and up propagation news from G3YLA and G4BAO

The cold, unsettled weather will ease its grip over the last few days of this week, ending the 28th of April, but only because the whole area of low pressure is moving across the country this weekend.

Low pressure remains close by for much of the following week and only a hesitant return of high pressure west of Ireland will improve things for western Britain at the end of the week.

The result is a chance of Tropo for western Britain next week, but it will probably be of limited quality since it is likely to form in cold, dry air across any temperature inversion.

The remaining option in such weather patterns is primarily rain scatter for those on the GHz bands. The many online weather radar displays can be used to highlight the areas of heaviest rain.

We are past the peak of the Lyrids meteor shower, but the Eta-Aquarids, with a Zenithal Hourly Rate of 50, peaks next Sunday the 5th around 2100UTC. Until then, rely upon random activity which tends to be better around dawn.

The Sun has been more active again recently, so monitor the clusters and Kp index for signs of geomagnetic activity and the chance of an aurora if the Kp index exceeds 5.

Sporadic-E tends to produce a few early examples in May ahead of its June peak. Check the DX clusters during the late afternoon or early evening as openings can be very brief early in the season. Start on the 10m band and, if short skip within Europe is present, move up to the 6m band. Digital modes are more sensitive so check FT8 reports to give clues as to where the chances are greatest.

For EME operators, the Moon is at minimum declination today, Sunday the 28th, meaning we’ll have short Moon windows to start the coming week. Path losses are falling but perigee, when the Moon is at its closest point, is still over a week away. 144MHz sky noise is high this weekend, ending the 28th of April, but falls too low by the end of the coming week.

And that’s all from the propagation team this week.

GB2RS News

Sunday the 21st of April 2024

The news headlines:

• Dr Stewart Bryant, G3YSX to continue as RSGB Board Chair
• The RSGB has vacancies for Regional Representatives
• The Radio Communications Foundation is recruiting new Trustees

The RSGB Board has met for the first time since the Society’s AGM where three Directors were endorsed to serve as Nominated Directors on the Board and one was confirmed as elected unopposed. The new Board has chosen Dr Stewart Bryant, G3YSX to continue in the role of RSGB Board Chair until the 2025 AGM. You can find details of all RSGB Board Directors on the Society’s website and the Board Liaison roles will be confirmed and added to the page in the coming weeks. Go to rsgb.org/board for more information.

At its recent AGM, the RSGB was delighted to confirm the unopposed election of five Regional Representatives. However, there are still vacancies for Regional Representatives in Region 11, which covers England South-West and the Channel Islands, and also Region 12 which is England East and East Anglia. These vacancies will be filled by co-option until the 2025 AGM. If you live in one of these areas and are passionate about amateur radio, keen to support local radio amateurs and clubs, and have the skills to lead a volunteer team of District Representatives in the region, this could be a role for you! To find out more, please contact Tony Miles, MM0TMZ who is the Board Liaison for the Regional Team via mm0tmz@rsgb.org.uk

The Radio Communications Foundation is a small charity dedicated to encouraging people to take up radio as a hobby or, in the case of youngsters, considering an RF-based career. The RCF is proud to sponsor Arkwright Scholars, work with the RSGB and Bletchley Park to deliver radio-building workshops and make grants for various projects around the UK. Further information is available via the RCF website at commsfoundation.org The RCF is now looking to recruit a couple of new Trustees to help it deliver its aims. Applicants should have an interest in radio communications and be prepared to be involved in decisions over grant-making, delivering RCF projects and attracting charity funding. The RCF would particularly like to hear from anyone with links to secondary education in the UK. Expressions of interest and applications should be sent to rcfsecretary@commsfoundation.org preferably by the end of June.

Following the introduction in February of the new Ofcom amateur radio licence conditions, the RSGB has continued to provide information and support to radio amateurs to help them make the most of the changes. This has included updates, club talks and a section of the AGM event focused on those licence changes. Go to the RSGB YouTube channel, choose the AGM recording from the ‘live’ tab and then watch two sections. Firstly, the main Board Q&A begins just after one hour and eighteen minutes into the event and includes some licensing questions from members. Secondly, a section from just before two hours and thirty-three minutes focused entirely on the new licence conditions and included three videos and a full live Q&A with four senior RSGB representatives. The Society has also published a wealth of information on its website which you can find at rsgb.org/licence-review

Nigel Limb, M7FFU, had a motorbike accident in 2015 that left him with permanent brain damage and partially blind in both eyes, but this didn’t stop him from pursuing his childhood dream of obtaining his amateur radio licence. In December 2023 he passed the Foundation Licence exam. In the early 1970s Sue Jacob, GW7YLS was a shortwave listener and interested in amateur radio, but it wasn’t until she retired and discovered that the exams no longer contained Morse code, that she decided to get more involved. Within 18 months she had passed all three licence levels. One of the great things about amateur radio is that it is accessible to everyone. The RSGB is celebrating this by collecting stories of radio amateurs who have passed their Foundation licence, or progressed through the licence levels, and are now discovering new aspects of amateur radio to enjoy. If you’d like to read more about Nigel, Sue and others, go to rsgb.org/student-stories and, if you’d like to share your story with the Society, email comms@rsgb.org.uk and the RSGB will use as many as possible.

A new amateur radio Facebook group has been formed for those who like getting out and about in motorhomes, campervans, and caravans. The group welcomes all radio enthusiasts. To find out more, or to join the group, search for ‘UK Motorhome and Amateur Radio Group’ on Facebook.

SOS Radio Week is an annual event that takes place throughout May to celebrate the work of the volunteers from the Royal National Lifeboat Institution, Independent Lifeboats and National Coastwatch Stations around the British Isles. Members of these organisations save many people between them who are in danger along and around the thousands of miles of coastline and further out to sea. This year is the 200th anniversary of the founding of the RNLI and SOS Radio Week is being co-branded SOS Radio Week 200 for those operators that are supporting the RNLI during the event. Participants can operate from home, a public location, or a lifeboat or Coastwatch station, with the appropriate authorisation from the station manager. A commemorative certificate will be available to all official stations that record their contacts on the website together with awards for the top individual and club, or group, stations on each band from 160m to 70cm. Registration for individual and group operators is available via sosradioweek.org.uk

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 18th of April 2024

Last week saw a welcome return of sunspots but, unfortunately, it also brought unsettled geomagnetic conditions.

By Thursday the 18th the solar flux index was back above 200, hitting 217. Compare that to the previous week’s 131 and you can see that there is a lot more activity. But, with 12 active regions visible, it looks like we could be in for a bumpy ride over the next seven days.

The Kp index hit five on the evening of Tuesday the 16th of April after the interplanetary magnetic field, or Bz, swung southwards, sparking visible aurora in the UK as far south as Dartmoor. This impacted the ionosphere, pushing MUFs over a 3,000km path down, with recovery not showing itself until 0930UTC on Wednesday the 17th.

The 10m band is struggling to open at times, although you may find FT8 still passing weak signals. SSB operators might be better advised to look at the 12 and 15m bands which may provide richer pickings.

Next week, NOAA predicts that the solar flux index may decline to be in the range of 170 at the beginning of the week, falling to between 135 and 140 at the end of the week. The risk of an M-class flare is currently at 75%, with an X-class event at 20%. Despite this, NOAA predicts the Kp index will be around 2 for all of next week. However, there is a chance that a flare and associated CME could scupper that completely.

If we do get a coronal mass ejection, or CME for short, we can expect the Kp index to rise roughly 48 hours after the event, perhaps hitting 5 or more and possibly sparking visible aurora from the UK again.

Overall then, it's good news on the sunspot front, but not so good for geomagnetic activity, which could see MUFs fall if any solar flares and CMEs come to fruition.

And now the VHF and up propagation news from G3YLA and G4BAO

The weather is likely to remain unsettled, despite temporary high pressure moving across the country this weekend. This may bring some Tropo, but it’s a cold air high and probably not the best for enhanced VHF conditions, except for localised overnight or early morning temporary lifts.

The rest of the time, there will continue to be an unsettled flavour to the weather so this leads to the possibility of rain scatter on the GHz bands, especially if we get heavy April showers.

This first weekend coincides with the peak of the Lyrid meteor shower which peaks tonight, the 21st and 22nd, so it’s worth checking the usual meteor scatter frequencies. If you are not familiar with meteor rates and variations from day to day, then visit the excellent Radio Meteor Observing Bulletin at rmob.org which gives an hourly display from various locations around the world. You can find many other useful links to meteor scatter resources by searching for ‘meteor scatter’ at rsgb.org

The Sun has woken up a little since last week, and a few auroral flutter signals on the LF bands suggest we shouldn’t give up yet for this spring. As usual, keep a watch for the Kp index going above 5.

The late April period can provide some fleeting early season Sporadic-E events, especially for the 10 and 6m bands. A couple of weak 5MHz Sporadic-E critical frequencies were noted during the late afternoon on Wednesday the 17th on the Dourbes plot shown at propquest.co.uk

For EME operators, Moon declination goes negative again today, the 21st, but path losses are falling as we passed apogee yesterday, the 20th. 144MHz sky noise is low but will rise to moderate by the end of next week.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 11th of April 2024

The Sun is still looking a little bare, but the solar flux index has climbed back to 131, as of Thursday the 11th, with four active regions. The promise is that things will improve, especially as we will soon see the return of active region 3615, which was the source of numerous M-class and one X-class flare on its last rotation.

Things have been a little sparse on the higher HF bands, with only FT8 being audible or visible on the 10m band at times. Having said that there has been some good FT8 DX to be worked on the 10m band, including Angola, Malawi, China, Japan, Taiwan and the Solomon Islands.

During the recent solar eclipse event there were also a lot of US stations on the 10m band using WSPR. These included Bob, K6XX in Santa Cruz, California, who was copiable in the UK at around 1850UTC. This just shows how effective WSPR is as a mode on an otherwise quiet band.

There have been some early signs of Sporadic-E on the 10m band using digital modes, including some brief openings to Scotland from eastern UK. We can expect these to improve as we head towards May.

Next week, NOAA predicts that the solar flux index will be in the 140 to 150 range with a maximum Kp index of three. If this is correct it means that HF conditions will be roughly the same as last week.

And now the VHF and up propagation news from G3YLA and G4BAO

The weather patterns are showing signs of change after being stuck for quite some time, and the main beneficiary will be VHF operators seeing a chance of Tropo returning to the bands.

The initial unsettled weather over the UK, with high pressure fixed over the continent, will take us through to the middle of the coming week.

Thereafter, a high will develop to the southwest of Britain midweek and drift northeast across the country, although some models take the high on a more southerly track. In either event, there should be some useful Tropo in the south and possibly northern areas too. This may be limited to southwestern areas for Tuesday's 23cm UK Activity Contest, but will hopefully be more supportive of the 4m UK Activity Contest on Thursday.

Meteor scatter is worth a look next week since we are approaching the 21st and 22nd of April peak of the Lyrids shower at the end of next weekend.

The quieter solar conditions have taken aurora down the table, but it's still good practice to watch out for if the Kp index goes above five.

Gigahertz-band rain scatter certainly drops down the league table next week as high pressure probably takes over.

As we said earlier, the next big thing is the start of the 2024 Sporadic-E season, which slowly comes to life during April for the 10 and 6m bands, especially on digital modes, whereas the real shift up in gear often comes during May. As mentioned last week, it’s worth updating your list of beacons in your rig’s memory while it’s still quiet.

For EME operators, Moon declination is at maximum this weekend, ending the 14th, so there will be long Moon windows. We are past perigee, so path losses are rising again. 144MHz sky noise is moderate this weekend then low for the rest of the week.

And that’s all from the propagation team this week.

A reminder that registration is open for Maritime Radio Day 2024 which takes place annually on the 14th and 15th of April. The event is held to commemorate the almost 100 years of wireless telegraphy service for seafarers which ended with the closure in the UK of Portishead Radio on the 30th of April 2000. Commencing at 1200UTC on the 14th of April, and finishing at 2300UTC on the 15th of April, this event is a great opportunity to have a QSO with ex-Marine Radio Officers and Coast Station professionals who exchange details of their previous ships and coast stations. The mode of operation is CW and all of the HF bands are used, including the WARC bands. A certificate of participation will be issued to everyone who submits results. Amateur licence holders are invited to register to take part in Friends of Maritime Radio Day. Shortwave listeners may also submit logs. For more information and to register, visit tinyurl.com/MRD24

Lots of stations are on the air today to join in with this year’s Airfields on the Air event. Amateurs are invited to contact as many of the stations as possible. To learn more about the event, and read a list of registered stations, visit tinyurl.com/2024AOTA

Tomorrow, the 8th, a total solar eclipse will head toward the UK from the west. While not visible over the UK, it will likely affect transatlantic VLF and HF radio propagation. RSGB Propagation Committee associate member Gwyn Griffiths, G3ZIL has a particular interest in the effect of reduced ionisation during the eclipse on second and third hops on 15 to 10m paths from the UK to North America. He encourages occasional WSPR users to dust off their transmitters to operate on those bands from today, the 7th, through to Tuesday the 9th of April, not just on the 8th, to provide results on undisturbed days.

And now for details of rallies and events

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 4th of April 2024

Looking at the Sun on Wednesday the 3rd of April, you might be forgiven for thinking we are near sunspot minimum!

With a near-total lack of sunspots and a solar flux index of 112, the solar disk was looking pretty bare. Compare that with just two weeks ago when the solar flux index was sitting at 209 on the 23rd of March.

But never fear, there seems to be some activity coming up. Two active regions, AR3627 and AR3628, have just rotated into view, but in the meantime make the most of the geomagnetically-quiet conditions.

10m propagation is still holding up, although you may find that the band opens a little later in the morning and shuts earlier in the afternoon. The 4X6TU and VK6RBP IBP beacons were both audible at 0945UTC on Thursday the 4th, while China, Japan, Mongolia and Thailand were copiable on 10m FT8, even with a lowish solar flux index.

Higher HF band propagation from the UK has moved from favouring North America to north-south paths, notably to South Africa and South America.

Next week, NOAA predicts that the solar flux index will rise a little, perhaps starting at around 135 and finishing at around 150. Geomagnetic conditions should be reasonably quiet with a maximum Kp index of 3, unless we get a coronal mass ejection that could send it soaring.

As always, keep an eye on solarham.net for current conditions.

And now the VHF and up propagation news from G3YLA and G4BAO

There have been reports of trans-equatorial QSOs on 144MHz from Southern Africa to the Southern Mediterranean, but here in the UK we can only dream due to our northerly location.

The next period of weather is unfortunately shaping up to be the same as most of the recent ones, dominated by low-pressure systems driving active weather fronts across the British Isles.

It means that Tropo conditions seem unlikely to feature much through to the end of the coming week. Rain scatter for the GHz bands remains the mode of choice with help from some heavy April showers. Meteor scatter options are still best with random meteors before dawn, but we are getting closer to the April Lyrids shower later this month, so not long to wait now.

The solar conditions have subsided a little recently, but we remain in scope for further activity, especially since April can be one of the more active months for Aurora. Watch out for fluttery signals on HF or VHF bands, use the various clusters, or save the frequency of one of the northern beacons in your rig’s memory.

This is a good time to suggest updating your list of favourite beacons on the 10, 6, 4 and 2m bands since they’ll be useful for the upcoming sporadic-E season too.

It’s a good time to take an early look at the sporadic-E prospects before it gets properly busy.

Some background rules which may help are to use propquest.co.uk to see where the jet streams are since Sporadic-E propagation is often associated with turbulence in regions of jet stream activity. Then look for a relatively low Kp index. The other main rules are related to timing. Usually, there are two windows of opportunity, one in the morning and a second in the late afternoon or early evening. However, at the beginning of the season, these are approximate.

Sporadic-E starts on the lower bands like 10m and, if strong enough, will gradually extend to the higher bands. The 10 and 6m bands are probably the ones to check this month.

For EME operators, Moon declination goes positive again on Sunday, which is also Moon perigee, its closest point to Earth, so we’ll see lengthening Moon windows, increasing elevation and low path losses. 144MHz sky noise is low until Monday’s total solar eclipse, then moderate for the rest of the week.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Wednesday the 27th of March 2024

What a tumultuous time we had last week. Active region 3614 produced an X1.1 solar flare and coronal mass ejection, or CME, in the early hours of the 23rd of March. This impacted Earth’s geomagnetic field sending the Kp index to 8 on the 24th of March.

There were simultaneous flares from active region 3614 and the larger region AR3615.

The solar wind speed reached more than 850 kilometres per second at the height of the geomagnetic storm, peaking at 880 kilometres per second.

The CME started to impact the Earth early in the afternoon of the 24th and, according to Digisonde data, its full effects on the ionosphere started to be felt by 1540UTC.

The large AR3615 sunspot cluster continues to evolve as it moves into the Sun’s southwest quadrant. Moderate flaring will remain likely in the short term with a lower chance for another strong X-class flare, although it is around the side of the Sun and is not considered a threat today, Sunday the 31st.

All this was not good news for HF propagation, which saw maximum useable frequencies over a 3,000km path plummet on the 24th to less than 18MHz. The ionosphere didn’t fully recover until two days later, with the MUF struggling to get above 18MHz on the 25th.

It wasn’t until the afternoon of Wednesday the 27th that we saw the 10m band behaving normally again with the Kp index back in the range of 1 to 3.

So, this is what can happen if we have an X-class flare and associated CME. We can expect more of the same to come.

Next week, NOAA predicts that the solar flux index will remain high at around 175 to 190. Unsettled geomagnetic conditions are forecast from the 3rd to the 5th of April when the Kp Index could rise to 4.

But keep an eye on solarham.net for a near real-time guide to current solar conditions.

And now the VHF and up propagation news from G3YLA and G4BAO

The period leading up to the Easter Weekend, and the following week shows up on the forecast charts as dominated by low pressure, feeding several periods of rain and showers across the country.

This unfortunately means that Tropo is again off the menu of weather-related VHF propagation.

Of course, wet weather is usually very supportive of rain scatter propagation on the GHz bands and this prolonged period of rain or showers will give the UHF and SHF operators something to occupy their time.

Meteor scatter prospects are once again just random, which tends to be better in the hours just before dawn. We can start to look forward to the April Lyrids, which are active in the second half of April with a peak around the 22nd. It’s worth checking out the operating conventions and frequencies now so that you can be ready.

Strong aurora has been reported recently, with a Kp index of 8, and a quick listen for fluttery signals on the 80m or 40m bands is often a good clue if you don’t have access to the Kp index at the time.

The main mode of interest for the coming months is Sporadic-E and some early propagation is possible, mainly on digital modes on the 10m or 6m bands, but probably very fleeting.

During the summer Sporadic-E season, it's well worth checking the propquest.co.uk graphs to see what is occurring and get an idea of how it may relate to jet stream weather patterns by cross-checking with the Sporadic-E blog upper air charts.

The Sporadic-E Probability Index, or EPI, maps are also potentially useful to see how the favourable regions change with time. In the current pre-season period, it’s more typical to find trans-equatorial propagation, or TEP, as an exotic mode offering paths to the south into South Africa and possibly into South America.

For EME operators, Moon declination reaches minimum on Easter Monday, so we’ll see short Moon windows with low elevation. Path losses are falling all week and 144MHz sky noise is moderate, rising to a peak of more than 3,000 Kelvin on Easter Monday before returning to low levels.

And that’s all from the propagation team this week.

The RSGB Planning Advisory Committee would like additional volunteers to join its advisory panel. Volunteers deal with queries from members about problems they face in getting planning permission for masts and antennas. These enquiries can be for support in making an application to the local council or in submitting an appeal. If you have a relevant professional background, not necessarily as a planner, or have some knowledge of how the planning system works, please get in touch. The Committee Chair will be happy to give you more information about what is involved and how you can help other radio amateurs. Find out more about the Committee on the RSGB website at rsgb.org/pac and then email John Mattocks, G4TEQ via pac.chairman@rsgb.org.uk to arrange a chat.

The April edition of RadCom contains the annual reports of the RSGB Committees, Honorary Officers, Teams and Groups. These reports give an overview of activities for the many important areas of the Society that support and develop amateur radio. You can also read them on the RSGB website if you go to rsgb.org/vlt and choose the committee reports section in the menu on the righthand side. The RSGB thanks all its many volunteers who give their time to support the Society and the amateur radio community.

Leicester Radio Society has launched an Amateur Radio Clubs on the Air activity this weekend, the 23rd and 24th. The aim of the activity is to encourage amateur radio clubs and societies to get on the air and operate. You can read details about an award that is available to both licensed amateurs and shortwave listeners by visiting the G3LRS page at QRZ.com

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 21st of March 2024

As we said last week – what a difference a month makes. Only in this case, what a difference a week makes!

On Friday the 15th, the solar flux index, or SFI, was at 129 and the Sun did not look very spotty at all. This week it’s all changed. On Thursday the 21st, the solar flux index stood at 176 with seven active regions visible.

For HF propagation forecasts, the golden rule is to use smoothed sunspot numbers, or SSN for short, rather than a daily figure – that is, sunspot numbers averaged over the past 12 months.

The current SSN is 129, which equates to a solar flux index of about 144. Perhaps the daily figure of 176 has the psychological effect of giving us confidence that the bands will be open!

A moderately strong M7.4 solar flare was observed around active region 3615 at 0736UTC on the 20th of March. The region continues to rotate into a better Earth-facing position and will remain a threat for additional solar flares above the M5.0 threshold.

If a flare leads to a coronal mass ejection or CME, we could expect a disturbed ionosphere roughly 48 hours later, depending upon the solar wind speed.

Also, a large coronal hole on the solar equator became Earth-facing on Thursday the 21st. A coronal hole is a lower-energy area on the Sun with open magnetic field lines that let solar plasma escape. This may lead to a geomagnetic disruption this weekend, ending today the 24th, with increased Kp numbers and a lowering of the maximum usable frequency.

Next week, NOAA predicts that the SFI will be in the 155 to 165 range. Geomagnetic conditions are hard to predict, due to coronal hole effects and CMEs, but NOAA puts the Kp figure at two to three. If we get a CME, this could easily rise to five or more.

Finally, we are now at the equinox which means that auroras are more likely due to the Russell-McPherron effect. The equinox is also a good time for north-south HF paths. Also, note that the HF bands are staying open for longer with the 4U1UN beacon in New York, the YV5B beacon in Venezuela, and the 4X6TU beacon in Israel audible on 14.100MHz around 2230UTC last week.

And now the VHF and up propagation news from G3YLA and G4BAO

It’s not good news for weather-related propagation with a total absence of high pressure on the charts again and a resulting lack of Tropo for the majority of the coming week.

But Tropo is not the only mode to be affected by the weather, rain scatter is too.

This has been a player quite often recently and, as we move into the spring, the characteristic ‘April showers’ can be very useful for rain scatter. Their effectiveness is related to the sixth power of the raindrop diameter, so the larger drops in heavier ‘April showers’ can be increasingly valuable on the GHz bands. Many good online weather radar displays are available to allow you to track them for maximum benefit.

Other promising mentions should go to Aurora which, as we said earlier, can be more likely around this time of the year when the Earth’s magnetic field is more favourably coupled to the solar wind. Meteor scatter is a lesser option and rests with random chance activity as we are still some way off from any major meteor showers.

Sporadic-E and related Trans-Equatorial Propagation, or TEP, in the shorter term during the next month or so, will soon be a major player. For TEP between Europe and southern Africa, check clusters around the middle part of the day. Although usually favouring stations in southern Europe, it can occasionally turn up for UK operators, particularly for those located in the southern half of the country.

As for Sporadic-E, the new season is starting to wake up, so the usual maxim of checking clusters is the best advice, starting with the 10m band and working up to the 6m band. The traditional morning and late afternoon ‘windows' are less reliable in early-season events, so just check anyway if you’re in the shack.

For EME operators, Moon declination is still positive, but going negative again this coming Monday. Path losses are at their maximum due to apogee on Saturday the 23rd. 144MHz sky noise is low but rising to moderate by the end of the coming week, reaching more than 1,000 Kelvin on Sunday the 31st.

And that’s all from the propagation team this week.

British Science Week is drawing to a close and lots of exciting activities have been going on. Radio amateurs across the country have been encouraging young people to explore and understand our hobby and there have been some wonderful ways of incorporating the theme of “Time” into amateur radio activities. The RSGB would like to thank those who have shared ideas and resources, promoting the magic of radio communications with young people. There will be a report in the June issue of RadCom to showcase the activities that have happened and to inspire people to get involved next year! Perhaps you ran a construction day, set up and operated a radio station in a school or achieved a QSO with GB3RS at the RSGB National Radio Centre. Whatever you’ve been doing, please send your reports, with separate high-resolution photographs, to radcom@rsgb.org.uk by the 21st of April 2024. The RSGB would welcome feedback about what worked well, what you learned and how the Society could develop its British Science Week activities next year. Please email the RSGB British Science Week Coordinator Ian Neal, M0KEO at bsw@rsgb.org.uk to share your thoughts.

Early in February the RSGB announced that the fees for Foundation, Intermediate and Full level examinations would increase from the 1st of May 2024. You can now use the online booking system to book an exam before the 1st of May at the current price or select exam dates from the 1st of May at the new prices. Please ensure you make the correct date selection, as booking errors that need to be changed may incur an administration fee as outlined in the exam terms and conditions. To book an exam, go to the Student Information section of the RSGB website and choose the option to book and pay for your exam from the right hand menu.

The RadCom Contesting column has new editors! The RSGB Contest Committees will be overseeing the column and have planned a schedule of topics. Some will be written by members of the three contesting committees, and some by others who can share their experiences. As well as information about various aspects of contesting, the committees hope that the column will feature a contesting tip of the month, a featured UK contester, as well as a contest of the month. Once each issue is published, the column content will be shared on the RSGB website to provide a useful resource about contesting. You can see a list of the planned topics at rsgb.org/radcom-contesting The committees are keen to hear from people who would like to be involved, so if you would like to suggest a missing topic or offer to write something for the column, please email ContestClub@rsgbcc.org

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 14th of March 2024

What a difference a month makes. We’ve gone from a solar flux index up to almost 200, to one that is down in the 120s.

Over the past week, we have had only two M-class solar flares, which means we have had limited coronal mass ejection activity and therefore low Kp indices.

Last weekend’s Commonwealth Contest saw UK amateurs making plenty of HF contacts, some with Australia, but everyone agreed that HF propagation was a little lacklustre.

There is a daily chance of moderate-class solar flares from AR 3607, the largest sunspot region, but all remaining spots remain mostly small and simple.

The solar wind speed has been quite high with sporadic periods of a south-pointing Bz field. This is what has pushed the Kp index to three, but this isn’t a big threat to HF. There is a slight chance of unsettled intervals caused by a weak coronal hole near the south centre of the solar disc coupled with the fast solar wind.

NOAA reports that active region 3590 has been detected on the far side of the Sun using helioseismology. This may mean that it will still be active and a threat when it returns in a week or so. This region was the source of the X6 solar flare on the 22nd of February – the largest so far in solar cycle 25.

Next week, commencing the 18th of March, NOAA predicts that the solar flux index will remain in the 120 to 130 range, although the US Air Force predicts it could reach 150. Geomagnetic conditions are likely to be mainly settled with a maximum Kp index of two or three.

So, this is a reasonable forecast for HF propagation, which should remain open up to 28MHz during daylight hours. This is also a good time for north-south paths, such as the UK to South Africa, and the UK to South America.

And now the VHF and up propagation news from G3YLA and G4BAO

The continuing theme of unsettled weather will produce further spells of rain and heavy showers and once again provide some rain scatter options on the GHz bands.

Another thing to mention is that, as we move towards the latter part of the month, the intensity of showers becomes greater due to the additional warmth improving the effectiveness of the rain scatter process.

It is very hard to find any traditional Tropo until we get well into the coming week. It may occur on Thursday the 21st when a high will develop a ridge from Biscay across southern Britain and the near continent. This should provide a chance of Tropo for the final few days of the coming week. Unfortunately, this is not in time for the UK Activity Contest on 1.3GHz on Tuesday the 19th, but the 70MHz UK Activity Contest on Thursday the 21st may be luckier.

The north of Britain may start to see the next low bringing rain over that weekend, so although it has an early exit from any Tropo, at least being well north gives Scottish stations a head start for any aurora, which tends to favour the spring months.

Meteor scatter remains in the random territory – try just before sunrise for best results. But with the next major shower being the Lyrids in late April, we have a while to wait for an uptick in activity.

Lastly, a brief mention of Sporadic-E. It has popped up with some weak events on the Dourbes plots on Propquest, but the main season is still a little way off.

Maybe check next month for a heads-up on the lower bands like 28 and 50MHz. Of course, digital modes will get a head start, so best to check the clusters and chatrooms for signs of fleeting activity. Some UK stations reported 50MHz trans-equatorial propagation to Africa last week, so check for that.

For EME operators, Moon declination reaches a maximum on Sunday, but path losses are starting to increase again. 144MHz sky noise is moderate, falling to low on Wednesday.

And that’s all from the propagation team this week.

The Edinburgh 23cm microwave beacon GB3EDN is back on the air after a move to a new location on the south side of Edinburgh. It has moved about 1.5km south from its previous site in the University of Edinburgh, King’s Buildings Campus. The operating frequency is 1296.990MHz. It sends its callsign and QRA locator in both FSK and JT4 once per minute. The new site is about 200m higher than the previous site and it is hoped that coverage is somewhat improved. It has a clear view from the northwest through to the east, giving good coverage up the east coast and across the North Sea to Scandinavia. It is also hoped that there will be better propagation to the south from the new site.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 7th of March 2024

As predicted, a coronal mass ejection, or CME for short, affected the ionosphere last weekend, the 2nd and 3rd of March, pushing maximum usable frequencies down and sparking auroral displays that were visible as far south as Cornwall.

The plasma hit the Earth around midday on Sunday the 3rd, eventually pushing the Kp index to more than 5 for nine hours. It eventually started to settle again, dropping to 4 for six hours, before then moving back to background levels by the morning of the 4th.

The solar wind speed was not that high, being around 350 kilometres per second, but the Bz component of the interplanetary magnetic field, or IMF, was pointing sharply south for a long period. This allowed the solar plasma to couple with the Earth’s magnetic field more easily, and it flooded in.

The maximum usable frequency was impacted, and it took until late morning on the 4th before the 10m band was usable again over a 3,000km path. This probably impacted northerly paths the most with southerly paths being relatively unscathed.

The rest of the week was generally free from coronal mass ejection chaos with the Kp index remaining below 3.

Attention is now turning to active region 3599, which has expanded in size. It may therefore be a threat for an M-class solar flare and potential CME.

Next week, commencing Monday the 11th, NOAA predicts that the solar flux index will be around 135, but may then increase to 170 by the 15th.

We are heading towards the equinox, which means that geomagnetic disturbances are likely to be more common and harsher. They are almost twice as likely in spring and autumn versus the winter and summer.

If the Kp index stays low, though, this can be a good time for HF.

And now the VHF and up propagation news from G3YLA and G4BAO

This weekend, the 9th and 10th, a strengthening southeasterly wind will develop over the country as low pressure moves into Biscay and a strong high builds over Scandinavia. Unfortunately, this may not be useful for Tropo since the high is a long way to the northeast and stronger winds usually prohibit the development of a quality inversion.

All this changes again over this second weekend of March, the 9th and 10th, as low pressure pushes fronts into southern Britain. It won’t last long though and a weak ridge will cross the country on Tuesday the 12th, which may bring some Tropo support for southeastern Britain into the continent for the 432MHz UK Activity Contest on Tuesday evening.

On Wednesday, an Atlantic low will cross northern areas with rain and possible rain scatter options, but this will soon clear to leave a weak high over the country and it’s a return to Tropo conditions for the remainder of the week.

The upshot of all this is that Tropo will be an off-and-on affair, but worth a look. The other modes, not so much. Although, as we said in the HF section, spring is a good time of the year for auroral activity and, after the recent visible aurora, we should keep a watch for activity and a high Kp index.

There has been the odd fleeting pulse of Sporadic-E showing on the Propquest graphs recently. This has been noticeable on the LF bands sometimes but is not yet a big player for the usual Sporadic-E bands of 10m, 6m and beyond. However, on digital modes, UK stations have seen 50MHz trans-equatorial propagation, or TEP, to Africa last week – so check for that.

For EME operators, Moon declination is still negative but goes positive again on Monday. Path losses are approaching minimum with perigee today, Sunday the 10th. 144MHz sky noise is low all week except today, the 10th, when the Sun is close to the Moon and in the beamwidth of antennas.

And that’s all from the propagation team this week.

Sunday the 3rd of March 2024

The news headlines:

• The Calling Notice for the RSGB’s 2024 AGM is now online
• New HF beacon list released by the RSGB’s Propagation Studies Committee
• The next RSGB Tonight@8 webinar is coming up

The Calling Notice for the RSGB’s 2024 AGM is now online. The Notice includes the resolutions and information about the three Nominated Directors who are being put forward for endorsement by RSGB members. You can also read the minutes of last year’s AGM. Voting opens on Wednesday the 13th of March. On that same day, you will be able to submit a question for the RSGB Board via a web form or register to ask a question via video on Zoom. For more information go to the Society’s website at rsgb.org/agm

The RSGB’s Propagation Studies Committee has released a new HF beacon list, with the 10m band listings completely revamped. The old list, which was started by Martin Harrison, G3USF Silent Key, had been added to over the years but was getting out of date. The only way to make it more accurate was to start again. The Propagation Studies Committee made use of the Reverse Beacon Network which wasn’t available when the list was originally created, plus listeners’ contributions from around the world. The new beacon list can be found at rsgb.org/beacons

Have you wondered what happens at a VHF National Field Day? Would you like to take part in one? In this month’s Tonight@8 webinar, on Monday the 4th of March, the RSGB offers two different perspectives. Firstly, RSGB VHF Contest Committee member Richard, G4HGI will talk about how the RSGB VHF Contest Committee uses the VHF Survey and other tools to formulate the rules and calendar for all VHF Contests, with specific emphasis on VHF National Field Day. Secondly, three members of the Lothians Radio Society, GM3HAM will explain how they organise and operate these hilltop events within the Scottish borders. The club has made a short, professional film capturing their 2023 VHF National Field Day weekend. They will show clips of that and of an old cinema film to show how this looked from a technical standpoint at much earlier club competition events in the 1970s. This will be a great evening so put it in your diary and be inspired! You can watch and ask questions live on the RSGB YouTube channel or a special BATC channel. Go to rsgb.org/webinars to find out more.

The RSGB has made two safeguarding announcements. Firstly, the Society’s safeguarding policy has been revised in line with modern practices and you can find it on the RSGB website at rsgb.org/policies Secondly, if your club relies on the RSGB’s affiliated club insurance for activities that may have a safeguarding requirement, it is important that you are aware of the conditions in Section 10 of that insurance. You can find the insurance details in your club portal on the RSGB website.

The Radio Society of Harrow is running a one-day classroom-style Foundation course on Saturday the 23rd of March at its venue in Watford. If you know anyone who would like to join the course, please tell them to email Brian, G3YKB at g3ykb@yahoo.co.uk There will be an optional extra session on the morning of the 24th.

Following complaints from some members, the RSGB has investigated a problem with the non-delivery of RadCom on Guernsey and the Isle of Man. It seems that following changes at Royal Mail, the labelling requirement for these copies was incorrectly applied by the printers and these copies didn’t go through the postal system correctly. The Society is sorry that this error has occurred and apologises for any inconvenience caused. It has, of course, asked its printers to ensure that there is no repetition of this problem, and the printer has paid for the two missing copies to be sent to each RSGB member in those areas. If your RadCom doesn’t arrive in future, please email the RSGB membership team via membership@rsgb.org.uk so they can send a replacement and track any wider problems.

Those who enjoy constructing and operating with low-power devices will be interested to know that a QRP conference is taking part in Rennes in the northwest of France on the 18th of May 2024. The event will include lectures and demonstrations and will be an ideal opportunity for the exchange of information between like-minded amateurs. The organisers are putting together a programme of speakers and are looking for contributors on every aspect of low-power design, construction and operation.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 29th of February 2024

Active region 3590, which was the large sunspot group that threatened us with solar flares and coronal mass ejections, or CMEs, has now moved to the Sun’s limb and is no longer a threat. Region 3590 was potentially dangerous but ultimately wasn’t too bad.

Yes, we had flares, but they were only minor C-class and M-class events. Three recent CMEs, which will all probably miss Earth, but with a risk of some glancing influence, are most likely to have arrived by this weekend, ending the 3rd of March.

However, old active region 3576 will begin to turn into view off the southeast limb by the end of today, the 3rd.

The Kp index rose to 4.67 during one three-hour period on Tuesday the 27th of February, but the disturbance was short-lived and HF propagation wasn’t too badly affected.

Speaking of which, there have been some good HF openings to the Pacific area over the last week. Spotted have been 3D2AG in Fiji on the 17m band, VK on the 10m band, and the H40WA Temotu DXpedition to the Solomon Islands. This latter DXpedition has mostly been spotted on FT8 Fox and Hounds mode in the UK.

The maximum usable frequency, or MUF, over a 3,000km path still remains above 28MHz during daytime, with MUFs over 14 to 15MHz at night. So, as we head into March and towards the spring equinox, HF is still looking good.

Next week, NOAA predicts the solar flux index will be in the range of 165 to 170. The Kp index is predicted to be two all week, but that is suspect and dependent on coronal mass ejections – or a lack of them. At this point in the cycle, anything could happen. With six or seven active regions visible, the risk of a flare and CME remains relatively high.

And now the VHF and up propagation news from G3YLA and G4BAO

The overall weather pattern remains very unsettled with further active lows and weather fronts crossing the country. There will also be periods with stronger winds and it may be cold enough for some wintry weather, especially over northern hills. The upshot of all this is that Tropo will once again be a rarity, but rain scatter may offer some comfort to those on the GHz bands.

Later in the coming week, high pressure will strengthen over Norway and this will produce quite strong winds over the North Sea and eastern UK and perhaps encourage paths to the east, but it’s probably marginal at best in terms of Tropo.

The prospects for aurora and meteor scatter are not especially reliable, but it was encouraging to hear of some digital activity on the 6m band earlier in the week to South Africa and Lesotho. This was probably the result of Trans Equatorial Propagation or TEP, as suggested in last week’s news.

The spring period is a fairly good time to listen for TEP, timed between the decay of the southern hemisphere summer Sporadic-E season and the start of the northern hemisphere summer Sporadic-E season. It’s well worth checking for similar activity during March for paths to the southern hemisphere via TEP. Signals can be strong enough for SSB or CW modes, so it is not exclusively for digital modes.

For EME operators, Moon declination drops to a minimum on Tuesday. Path losses are past their peak now and falling until perigee on Sunday the 10th. 144MHz sky noise is moderate to high, reaching a peak of over 2,500 Kelvin on Tuesday the 12th.

And that’s all from the propagation team this week.

GB2RS News

Sunday the 25th of February 2024

The news headlines:

• New amateur radio licence conditions are effective
• Amateurs are reminded to carry out EMF assessments
• The 2024 Band Plans have been published

Ofcom has released its final decisions following its consultation on the amateur radio licensing framework last year. Revised licence conditions became effective on Wednesday the 21st of February 2024. The changes to licence conditions include the optional use of Regional Secondary Locators, increased transmitter power levels and provide a greater opportunity to bring newcomers into amateur radio. There are approximately 100,000 amateur radio licences issued by Ofcom in the UK. Ofcom says that it will shortly be contacting all licensees to provide each with their new licence document. Ofcom is aiming to reissue all UK amateur radio licences by the autumn of 2024. To help this process run as efficiently as possible, please ensure that your contact details are up to date in the Ofcom licensing system. Further updates to the amateur radio licensing framework, including the issuing of M8 and M9 Intermediate callsigns, will be rolled out in two more phases later this year and in the 2024/25 year. A video entitled ‘Updating the amateur radio licensing framework: RSGB overview of key changes’ is available in the Ofcom playlist on the RSGB’s YouTube channel which you can find at youtube.com/theRSGB In it, RSGB General Manager Steve Thomas, M1ACB and RSGB Spectrum Forum Chair Murray Niman, G6JYB discuss the impact of the new rules. They also describe how the RSGB worked with Ofcom before and during the consultation period to arrive at the best outcome for all UK amateurs. Steve, Murray, and many people across the RSGB have also worked hard to engage with individual amateurs, and amateur radio clubs and groups, to help them prepare for the licensing changes. The RSGB will continue to release information and support for radio amateurs as we all adapt to the new arrangements. You can read more details and guidance on the Ofcom website at tinyurl.com/ARFEB2024 or via the RSGB website at rsgb.org/licensing

Given that increased transmitter power limits are now available to UK licensees, all amateurs are reminded that they are required to carry out EMF assessments. To help you do this, advice and an online EMF calculator can be found at rsgb.org/emf

The RSGB Band Plans for 2024 were published in the March issue of RadCom. They are also available via the RSGB website at rsgb.org/bandplans This year’s changes support the new Ofcom licensing framework and guidance, particularly in the VHF and UHF bands. All amateurs are reminded to consult the Band Plans before operating.

The list of amateur radio events taking place in British Science Week and the resource suggestions are growing. GB3RS, the radio station at the RSGB National Radio Centre at Bletchley Park could be available for QSOs with stations operating as part of British Science Week. Contact the RSGB’s BSW coordinator, Ian Neal, M0KEO at bsw@rsgb.org.uk and he will link you with the NRC Coordinator Martyn Baker, G0GMB to make your arrangements. Please continue to send to Ian the resources you’d like to share and details of British Science Week events you’re organising, including the times you’ll be on the air. The RSGB would like to inspire as many people and groups as possible to get involved! You can access all event and resource details on the RSGB website at rsgb.org/bsw

The RSGB has been trialling paper wrappers for RadCom as part of its plans to be more environmentally friendly. The Society has been collating feedback and is aware that there have been particular problems with the glueing of the RadCom wrappers this month. Please be assured that the RSGB is discussing this with its supplier to try to resolve the problem before the next issue.

During a year when the global landscape shifted once more, with conflicts across the world and economic difficulties touching the lives of individuals, the RSGB was pleased to see that the amateur radio community continues to thrive. It may have changed shape and adapted with the times, but the Society has been there not only to support its members but to defend the spectrum and provide information for all radio amateurs. In the March RadCom, there is a feature called ‘A year in numbers’ which shows some of the great things to celebrate, in which RSGB HQ staff have often led the way. There is an infographic and a short video with the highlights, and you can read the fuller story from page 40 in RadCom and on the website. Go to rsgb.org/strategy-updates and click on “2023 - a year in numbers”. The April RadCom will show in detail the work of the RSGB committees and other specialist volunteers.

The amateur radio licence exams will be updated in line with the new licence conditions decided by Ofcom this week. Further information about the timing of those changes can be found on the RSGB website at rsgb.org/syllabus2019

Registration is open for the Mills on the Air event which will take place on Saturday the 11th and Sunday the 12th of May. To read more about the event, register and view a list of stations that are taking part, visit ddars.net and follow the “mills on the air” link.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 22nd of February 2024

We’ve had two X-class solar flares over the past few days. The first occurred at 2307UTC on the 21st of February, so didn’t affect the UK at all. The second erupted at 0632UTC on the 22nd of February and was too early to affect the ionosphere in this region. However, HF paths to the east may have been affected.

However, active region 3590 could cause more problems as it rotates into an Earth-facing position. Look out for more flares and potential coronal mass ejections as we head into the weekend.

Another problem is a coronal hole on the solar equator, which was Earth-facing on Friday the 23rd and could lead to an increased Kp index today, the 25th if its associated Bz magnetic field points south.

Although there are only two sunspot groups visible, the solar flux index is 170, showing just how potent these spots are.

Daytime MUFs over a 3,000km path are still exceeding 35MHz, while nighttime MUFs over a similar distance struggle to get above 10 to 11MHz.

With the daytime MUF so high, it is a good opportunity to check for low-power 10m beacons. The RSGB’s Propagation Studies Committee has just released a new 10m beacon list, which has been created from scratch using the reverse beacon network and help from amateurs around the world.

The new beacon list, which can be found under the Propagation section of the RSGB website at rsgb.org/beacons should be more useful than its predecessor as it is based on actual beacons that have been received. But if you hear any beacon that is not on the list, please inform Steve, G0KYA at psc.chairman@rsgb.org.uk

Next week, NOAA predicts that the solar flux index may decline a little into the 160s. As for geomagnetic conditions, it all depends upon what happens with active region 3590. We could be in for a rough ride, or things could be fine – let’s wait and see.

And now the VHF and up propagation news from G3YLA and G4BAO

The current spell of unsettled weather continues, and this means that Tropo won’t be worth waiting for, other than any temporary short-lived early morning temperature inversions, especially if accompanied by misty low cloud or fog.

The main part of the story is again rain scatter, which will have plenty of opportunity to shine in the period to the end of the coming week. Summer thunderstorms are usually full of large raindrops, while winter systems are generally less intense but, in the absence of much else, it’s still worth considering for those on the GHz bands.

The other propagation modes of meteor scatter or aurora are even longer shots, but they may still crop up. The best time for random meteor scatter QSOs is around dawn.

Lastly, the doldrums for Sporadic-E propagation are still with us and don’t expect too much until we are well into April, even on the 10m band.

The high solar flux could see some trans-equatorial 50MHz openings if the Kp index remains low, especially for the far south and west of the UK.

For EME operators, Moon declination starts the weekend positive but drops negative again on Monday. With apogee, when the Moon is at its furthest point from Earth, occurring yesterday, Saturday the 24th, path losses are at their highest for the month this weekend. 144MHz sky noise is low all week.

And that’s all from the propagation team this week.

Over the last few years, the RSGB has been developing the way in which the Board can be asked questions at the Society’s online AGMs. Last year people were able to ask questions via the YouTube live chat as well as submitting written questions in advance. This year, in response to members’ feedback, there will be an opportunity to ask a question on video via Zoom. The RSGB Board will still take written questions in advance and will also answer as many questions on the day via the live chat as possible, depending on the time. The RSGB AGM will be held on Saturday the 13th of April and you can find more information about how to take part on the Q&A subpage of the RSGB AGM web section at rsgb.org/agm

The RSGB has a collection of resources to help you get involved with British Science Week, which runs from the 8th to the 17th of March this year and has the theme of ‘Time’. If you already have something planned, please let the RSGB know. This will be useful for others to see and might inspire them! There are already several events for British Science Week on the RSGB website. Some of these are open to everyone, so please show your support for them. If you’re going on the air, tell everyone when to listen out for you by sending the RSGB dates, times, bands and modes. The RSGB’s British Science Week coordinator is Ian Neal, M0KEO and you can contact him via bsw@rsgb.org.uk Please send Ian the resources you’d like to share and your event details including the times you’ll be on the air. All details are on the RSGB website at rsgb.org/bsw

Registration is now open for Maritime Radio Day 2024 which takes place annually on the 14th and 15th of April. The event is held to commemorate the almost 100 years of wireless telegraphy service for seafarers which ended with the closure in the UK of Portishead Radio on the 30th of April 2000. Commencing at 1200UTC on the 14th of April, and finishing at 2300UTC on the 15th of April, this event is a great opportunity to have a QSO with ex-Marine Radio Officers and Coast Station professionals who exchange details of their previous ships and coast stations. The mode of operation is CW and all of the HF bands are used, including the WARC bands. A certificate of participation will be issued to everyone who submits results. Amateur licence holders are invited to register to take part in Friends of Maritime Radio Day. Shortwave listeners may also submit logs. For more information and to register, visit tinyurl.com/MRD24

There are less than two weeks to go until the deadline for the RSGB Construction Competition. There are six categories to enter this year: Antennas; Beginners; Most creative and/or elegant PCB Design; Construction Excellence; Innovation; and Software and Systems. To enable members from across the country, and even the world, to enter, entries will again be judged over the internet rather than in person. Special recognition will be given to entries submitted by radio amateurs under the age of 24, and to those who have just gained their Foundation licence. A cash prize will be awarded to the winner of each section, with a bonus for the overall winner, who will also be declared the winner of the Pat Hawker G3VA Award. You can find out more, including how to enter, on the RSGB website at rsgb.org/construction-competition Don’t forget, the deadline for entries is the 1st of March 2024 so get your entry in before it’s too late.

Many amateur radio stations have been on the air this weekend, in conjunction with The Guide Association, to celebrate World Thinking Day on the Air. The aim of World Thinking Day on the Air is to encourage Guides to make friendships with members of other units, using amateur radio as the means of communication. If you, or your club or society, were on the air during the event don’t forget to send your pictures and stories to radcom@rsgb.org.uk Please send your reports in by the 23rd of March.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 15th of February 2024

We had an interesting week with the threat of a major coronal mass ejection at any time with so much sunspot activity. In the end, it pretty much amounted to nothing, with the highest Kp index only reaching 4.33 on February 11th.

That’s not to say we didn’t have solar activity. Far from it, as the solar flux index reached 208 on the 12th and has been consistently above 180 all week. We also had high proton levels as the positively charged particles streamed past Earth. This was the result of an eruption early on Monday morning from beyond the southwest limb. This may have affected HF signals going over the poles.

Otherwise, we had numerous low-level solar flares to contend with, but none of them were stronger than M-class and so of little consequence.

So where did this leave us in terms of HF propagation? All in all, not bad with maximum usable frequencies, or MUFs for short, over 3,000km consistently above 28MHz in daylight hours. Daytime MUFs were peaking above 33MHz according to the Dourbes ionosonde.

Looking further ahead, we are now heading towards the equinox period, so we can expect MUFs to fall from their winter highs. The good news is that we can expect north-south paths to improve. The equinox is traditionally a better time for auroral conditions.

If you want to work the USA on 28MHz you still have a couple of months left to do so, but expect transatlantic propagation conditions to decline by the time April arrives. The good news is that propagation to South Africa, South America and the Caribbean may improve.

Next week, NOAA predicts that the solar flux index may reduce and be in the range of 155 to 165. Geomagnetic conditions are predicted to be quiet but, as always, keep an eye on solarham.net for a near real-time update as the risk of a coronal mass ejection, or CME, remains high. To recap, an Earth-facing CME could increase the Kp index, reduce MUFs and generally give poor HF propagation for up to a day.

And now the VHF and up propagation news from G3YLA and G4BAO

The basic weather pattern remains unsettled with a series of frontal systems crossing the country during the period. This leaves little room for any Tropo other than the occasional transient ridge of high pressure between successive weather systems. It does however give plenty of scope for rain-scatter enthusiasts to try their luck on the GHz bands.

The solar conditions continue to give hope for an increased geomagnetic Kp index, which would be a good signal for potential aurora if it goes above 5 as evidenced in visual displays over northern Britain last Tuesday night, the 13th and 14th of February.

As usual, the other propagation modes can still surprise us, even though this is not strictly the best time of year. The large number of satellites in operation means that QSOs can be guaranteed even with simple hand-held equipment. So, have a look at the AMSAT-UK pages and the RSGB website for details and give it a go!

Also, a reminder that the best time for random meteor scatter QSOs is around dawn and that the high solar flux could see some 50MHz openings if the Kp index remains low, especially for the far South and West of the UK.

For EME operators, the moon reaches peak declination today, Sunday the 18th, so activity should be higher with high peak moon elevations and long moon windows. Path losses are moderate but rising and 144MHz sky noise is moderate, but falling after Monday.

And that’s all from the propagation team this week.

GB2RS News

Sunday the 11th of February 2024

The news headlines:

• The outcome of the RSGB 2024 Board and Regional Team election process
• RSGB challenge for British Science Week announced
• RSGB Spectrum Forum updates

The RSGB has announced the outcome of its 2024 Board and Regional Team election process. These results come into force at the RSGB 2024 AGM and, until that time, the current Regional Representatives remain in their roles. The announcement also contains news of the Nominated Directors put forward for endorsement by the RSGB membership next month, as well as two co-options to the RSGB Board, effective until the AGM. For full details of the announcement and the candidates go to the RSGB AGM web page at rsgb.org/agm

The theme of British Science Week this year is Time. Both time and the closely related concept of frequency, are of vital importance to radio communications. The RSGB has announced a new challenge for British Science Week linked to this theme. The challenge has categories for every age group and the winner of each group will win a prize. The deadline for entries is the 1st of September and the results will be announced at the RSGB Convention in October. The challenge is as follows: “Using readily available components, material or other resources, provide a method of either measuring the frequency of a radio frequency source or signal or providing a time reference to a radio operator or radio system”. For more details about the challenge, as well as activities to inspire you and resources to help you take part in British Science Week, go to the RSGB website at rsgb.org/bsw

A busy year has seen several online Spectrum Forum meetings. Two meetings held in January considered the Ofcom notice period for ‘representations’ and areas where band plan adjustments would be needed, as well as more regular items such as annual group reports.

The RSGB website now has these details online. The RSGB’s reply to Ofcom has been added to its special focus page on the Ofcom licence review. Along with other recent representations, this will enable Ofcom to finalise the new licence later this month. The RSGB Spectrum Forum pages have also been updated with the January 2024 group reports and meeting notes, which included the discussions on the provisional changes. To read more, visit rsgb.org/spectrumforum

As previously announced by the RSGB Examinations Standards Committee Chair, Tony Kent, G8PBH, the amateur radio licence examinations will need to change to reflect the changes to the licence conditions announced by Ofcom. The scale of the licence changes will have a significant impact on Section 1 of the syllabus, ‘Licensing’, and a small impact on Section 7, ‘Operating’. Ofcom is currently reviewing representations and will publish its final decision, including the final version of the licence, before the 21st of February. The new licence will come into effect before work on the syllabus and examination question bank is completed. The RSGB Examinations Standards Committee has gained approval from Ofcom to continue to examine the current licence conditions for a period of six months following the publication of the new licence. This will allow trainers time to update their courses in line with the new syllabus, and allow candidates that have started their training under the current licence conditions to complete their courses and take the exam. It is expected that examinations of the new licence conditions will begin on the 1st of September 2024. For full details, see the exam announcements page on the RSGB website.

The first amateur radio station on the moon, JS1YMG, is now transmitting. The Japan Aerospace Exploration Agency, or JAXA, landed its Smart Lander for Investigating the Moon on the 19th of January 2024. The JAXA Ham Radio Club, JQ1ZVI secured the JS1YMG callsign and has been transmitting Morse code on 437.41MHz since the 19th of January. The probe uses 1W to a UHF antenna, with circular polarisation, and is transmitting what is described as "matters related to amateur business." Radio amateurs have been busy analysing JS1YMG's signal. You can read more about this story on Daniel Estévez, EA4GPZ’s blog at destevez.net

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 8th of February 2024

A large sunspot region has been turning into an Earth-facing position and now looks like it could be threatening. Active region 3576 has already emitted a couple of low-class solar flares but could be poised for even more.

An M5.1 solar flare was detected around region 3575 on the 7th of February as well. Updated imagery shows that an associated coronal mass ejection, or CME, was likely however, due to the location near the Sun’s south-west limb, it was directed mostly away from Earth.

The solar flux index remained high this week, hitting 190 on the 6th before dropping to 188 on the 8th. Geomagnetically, the Sun has been behaving itself with a maximum Kp index of only three on Sunday the 4th.

But all eyes will be on active region 3576 next week as it could upset the apple cart.

Meanwhile, daylight maximum usable frequencies over a 3,000km path remain more than 28MHz, which is good for HF.

Next week, NOAA predicts that the solar flux index may decline to be in the range of 160 to 170. Geomagnetic conditions are also predicted to be settled with a low Kp index. However, as we said earlier, that could all change if we have a violent solar flare and associated coronal mass ejection from region 3576 or any of the many other sunspots.

And now the VHF and up propagation news from G3YLA and G4BAO

Unsettled weather describes the pattern for the coming week, including some colder weather mixed in to provide snowfall for some areas, particularly in northern areas. This characteristic weather type will mean little chance of Tropo during the period.

Other propagation modes of interest might be even harder to find unless you are thinking of rain scatter, which could be useful for a few suitably-equipped stations on the GHz bands. Other modes, such as meteor scatter or aurora, are also looking a bit thin. There is always the chance of some random activity, unlike Sporadic-E which is in its late winter lull that usually lasts until April for the 10 and 6m bands.

For EME operators, Moon declination is negative and rising, going positive on Monday the 12th. So there will be higher peak Moon elevations and longer Moon windows throughout the week. Path losses were at their lowest at perigee on Saturday the 10th.

144MHz Sky noise is moderate to low.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 1st of February 2024

We had another week of relatively calm geomagnetic conditions with a maximum Kp index of three. The solar flux index declined from 172 on the 24th to 135 on the 30th.

Nevertheless, that is still enough to support propagation on the 10m band, with the maximum usable frequency over a 3,000km path generally being between 29 and 36MHz during daylight.

Solar activity has been at low levels with only minor C-class flares and one M-class flare detected. Active region 3559 is now located behind the west limb of the Sun and out of direct view. New active region 3567 in the northeast quadrant is showing the most promise as it appears to be in a growth phase. There is currently a 25% chance of a moderate M-class flare, according to the latest NOAA and SWPC update.

Earlier in the week, we had a period of moderate S2-level radiation storming. Proton levels streaming past Earth, following a solar flare early on Monday morning, increased but this has now declined.

A minor coronal hole also became Earth-facing on the 2nd of February, so we may still expect some disruption today, Sunday the 4th.

The 10m band is still romping along, with beacons along the eastern seaboard of the USA coming alive in the afternoon. This weekend, the 3rd and 4th, sees the 10-10 International Winter SSB Contest, so there should be plenty of stations to work on 28MHz.

Next week, NOAA predicts that the solar flux index may rise again, perhaps to 150 today Sunday 4th, and up to 165 a week later. We may have unsettled geomagnetic conditions on the 5th and 6th, with the Kp index predicted to rise to three.

And now the VHF and up propagation news from G3YLA and G4BAO

This week, ending the 4th of February, saw high pressure to the south of Britain and fronts over northern areas. For some stations in the southern half of the country, there could be useful Tropo conditions for the 432MHz Affiliated Societies Contest taking place today, the 4th.

Unfortunately, the frontal activity over the north will move south on Tuesday to remove any chance of these better conditions lasting into the 144MHz UK Activity Contest on Tuesday the 6th of February.

The period from mid-week onwards looks dominated by low pressure with rain or showers and generally flat VHF and UHF prospects unless you are set up for rain scatter. Other propagation modes like meteor scatter, aurora or Sporadic-E seem likely to remain in the background for the coming week.

For EME operators, moon declination is negative and falling to a minimum on Tuesday the 6th. Path losses are also decreasing since their maximum at apogee on Monday the 29th. But with the low peak moon elevations, only eight degrees on Tuesday, moon windows will be short.

144MHz sky noise is moderate to very high all week going over 3100 Kelvin on Tuesday the 6th. Friday and Saturday see the moon and sun very close together, so Sun noise in antenna beamwidths will be an issue.

And that’s all from the propagation team this week.

GB2RS News

Sunday the 28th of January 2024

The news headlines:

• The RSGB election deadline is coming up
• RSGB Build a Radio workshop planned at Bletchley Park
• Registration for SOS Radio Week is open

The deadline for nominations in the RSGB elections is next Wednesday, the 31st of January. If you would like to stand for the one elected Director role, or any of the eight Regional Representative vacancies, you will need to complete the nomination process by 2359UTC on Wednesday. Full details of the process are on the RSGB website at rsgb.org/election The Society would encourage anyone with a passion for amateur radio, and a desire to support the amateur radio community, to look at the candidate information and consider stepping forward for one of these roles. You’ll find full information about the skills and experience needed in the candidate packs, and there is still time for an informal chat about the roles and responsibilities if you’d like one. But don’t delay as late applications won’t be accepted!

As part of its British Science Week activities, the RSGB is organising two build-a-radio workshops at Bletchley Park on Sunday the 17th of March. Funded by the Radio Communications Foundation, these fun workshops are a great way for young people to try a practical amateur radio activity. The sessions are for youngsters aged 11 to 18 who will build their own VHF FM broadcast receiver using simple tools. The workshops cost £11 for the participant, and if you are an adult accompanying a participant who is aged 16 or under, you will receive free admission to Bletchley Park. These workshops are always very popular so book now if you know a youngster who would like to take part. Go to the Bletchley Park website at bletchleypark.org.uk then choose the What’s On option from the top right-hand menu.

SOS Radio Week is an annual event that takes place throughout May to celebrate the work of the volunteers from the Royal National Lifeboat Institution, Independent Lifeboats and National Coastwatch Stations around the British Isles. Members of these organisations save many people who are in danger along, and around, the thousands of miles of coastline and further out to sea. This year is the 200th anniversary of the founding of the RNLI, so SOS Radio Week is being branded ‘SOS Radio Week 200’ for those operators who are supporting the RNLI during the event. Participants can operate from home, a public location, or a lifeboat or Coast watch station, with the appropriate authorisation from the station manager. A commemorative certificate will be available to all official stations that record their contacts on the website, together with awards for the top individual and club, or group, stations on each band from 160m to 70cm. Registration for individual and group operators is now open via sosradioweek.org.uk

The RSGB has released a further three presentations from its 2023 Convention. In the first, Professor Simon Watts, G3XXH gives a fascinating presentation about VHF airborne radar and the design and performance of these early systems in World War II. The other two presentations focus on the World Radiosport Team Championship which the UK will be hosting in 2026. The WRTC is held every four years and is considered to be the Olympic Games of radio contesting. At the RSGB Convention, WRTC Chair Mark Haynes, M0DXR gave an overview of what is being planned and how people can get involved either as a spectator, volunteer, competitor or referee. John Warburton, G4IRN gave his perspective on what it is like to be a WRTC referee. The full WRTC planning team also gave an update recently on an RSGB Tonight@8 live webinar. You can see all of these presentations on the RSGB YouTube channel at youtube.com/theRSGB

RadCom Basics aims to help newcomers to amateur radio develop their knowledge and experience. Others enjoy reading it as it helps remind them of things they have forgotten or practise a skill they have not used for a while. The January 2024 issue of RadCom Basics is now available. It contains articles that provide advice on getting started with Bunkers on the Air, working on the 160 and 80m bands, constructing a multi-band vertical antenna, and more. You can find RadCom Basics at rsgb.org/radcom-basics

The latest issue of RadCom Plus, the online magazine for the more technically-minded radio amateur, was published this week. The first article, by Tom Alldread, VA7TA, is about how to make a protection filter for an SDR or VNA. Following this is a contribution from Sheldon Hutchison, N6JJA who discusses how to make an effective antenna noise canceller. You may recall the article by Andy, G0FVI in October’s RadCom which discussed the principles of antenna noise cancellation. Sheldon investigates exactly how the canceller should work, and his investigations have resulted in his superior design which you can construct for yourself. The third article, by Michael Toia, K3MT, is all about understanding the relationship between a train of square pulses and the harmonic content of its frequency spectrum, not with complicated mathematics, but by using an entirely diagrammatic approach. Those less familiar with mathematics might especially find this article helpful. This issue of RadCom Plus ends with Andy Nehan, G4HUE discussing the design of analogue power supplies. Members of the RSGB can access RadCom Plus via rsgb.org/radcom-plus

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 25th of January 2024

We dodged a bullet last week when a coronal mass ejection, or CME, was predicted to be heading our way. In the end, it came to nothing.

The CME observed on the 20th of January was expected to pass Earth and deliver possible G2 storm conditions. But a solar wind enhancement, possibly associated with the plasma cloud passing near Earth, saw the Kp index rise to only 3.67 on Wednesday the 24th.

The many solar flares, and associated coronal mass ejections, over the past few days make it difficult to give a reliable geomagnetic forecast. Over the past seven days, there have been more than 60 C-class and 18 M-class flares, typical for this point in the solar cycle. Sunspot-wise, the solar flux index has remained high, being more than 170 all week.

Critical frequencies have often exceeded 11MHz during daylight hours, which means the 30m band, as well as the 40m band, should be open around the UK. However, nighttime critical frequencies have fallen below 4MHz, meaning that even the 80m band struggles at times.

We mentioned last week that the NCDXF beacon VK6RBP in Australia had been heard on 28.200MHz. If you’ve copied VK6RBP you might be interested in trying for some other lower-power Australian beacons on the 10m band. Try listening for the 8W VK4LA/B on 28.206MHz in Brisbane, or perhaps the 10W VK4RST, which is 550km north-west of Brisbane, on 28.266MHz.

Next week, NOAA predicts the solar flux index will be in the range of 155 to 175. Geomagnetic conditions are forecast to be quiet, other than on the 29th of January when the Kp index is predicted to rise to three. But, as always, keep an eye on solarham.net for a near real-time report.

And now the VHF and up propagation news from G3YLA and G4BAO

Today, the 28th, sees the UK recovering from the two named storms and just getting settled into moving high pressure across northern France, with a second centre crossing central Britain early next week. This offers a chance of Tropo, especially in the south, while fronts continue to affect Scotland.

After the middle of the coming week, a more unsettled pattern returns with fronts crossing the country, which might bring some rain scatter for the GHz bands. But, in general, the picture remains unsettled into the end of the week and doesn’t look too exciting for the 432MHz Affiliated Societies Contest on Sunday the 4th of February.

Other propagation modes that are worth considering are all relatively low-key in the transition into February. This means that meteor scatter is best looked for in the early pre-dawn period when random meteor activity peaks.

The other chance might be aurora, and this is simply about checking the behaviour of the Kp index, which measures the disturbance of the earth’s magnetic field by solar activity. Kp indices higher than six are a good sign for aurora.

It looks like we are in a quiet period for Sporadic-E propagation.

For EME operators, Moon declination is positive and falling, going negative again on the 30th. Path losses reach their maximum at apogee on Monday the 29th, then start to fall again. 144MHz sky noise is low all week.

And that’s all from the propagation team this week.

GB2RS News

Sunday the 21st of January 2024

The news headlines:

• British Science Week is approaching
• Updates on the RSGB’s Strategic Priorities
• RSGB election deadline reminder

This year’s British Science Week runs from the 8th to the 17th of March with the theme of Time. This event is a fantastic opportunity to raise awareness of amateur radio in your local area. The RSGB has some great activity ideas you could try at your local school, Scout or Guiding group or local youth club. Go to the web page at rsgb.org/bsw and click on the activity titles to find everything you need to know to be able to run that activity. Several radio clubs from across the UK have already planned outreach activities for British Science Week and the RSGB hopes its resources will inspire you to get involved too! RSGB volunteer John Hislop, G7OHO has provided these ideas but the Society would love to add other activities to enthuse young people about wireless communication. If you have an amateur radio activity on the theme of Time that you’d like to share, or if you’d like to get involved but aren’t sure how to start, please direct enquiries to the RSGB British Science Week contact, Ian Neal, M0KEO. Ian’s contact details will soon be available at rsgb.org/bsw

At the Discussion with the Board session at the RSGB 2023 Convention, the RSGB President, John McCullagh, GI4BWM confirmed that the Board would keep members updated regularly on progress with the new strategic priorities. Two updates have now appeared in the January and February issues of RadCom and they are also available to read on the RSGB website. These updates highlight some important activities and achievements as well as new plans, so the Society encourages every member to take the time to read them. Go to rsgb.org/strategy and choose the ‘Strategy priorities updates’ option from the righthand list. Further updates are being prepared so do check back regularly or look out for them in each RadCom. You can also watch the Discussion with the Board Convention session on the RSGB’s YouTube channel at youtube.com/theRSGB

The deadline for applications for the one elected RSGB Board Director position and eight Regional Representative roles is Wednesday the 31st of January. Amateur radio needs a strong and active national society so don’t leave it to everyone else, step forward for one of these roles and play your part in the future of the RSGB. You'll find guidance and candidate forms on the RSGB elections web page at rsgb.org/election as well as contact details if you want an informal chat before standing for election.

A reminder that the RSGB is looking for four licensed radio amateurs to help raise the profile of wireless communication amongst young people across the UK. We have had a good response, but we’d still like to hear from prospective volunteers in Northern Ireland and Wales. These volunteer Youth Country Representatives will represent the RSGB at externally organised events and will plan and deliver outreach activities. If you have plenty of ideas, a passion for getting young people involved in amateur radio and experience of running small-scale events, we would be very keen to hear from you. The deadline is Friday the 16th of February. For full details, see rsgb.org/volunteers and for an informal discussion, please email RSGB Board Director, Ben Lloyd, GW4BML at gw4bml@rsgb.org.uk

GB2RS began broadcasting via the Es’hail-2 amateur satellite in May 2021. Every Sunday at 0800UTC you can hear the latest RSGB news on the dedicated narrow-band QO-100 transponder frequency of 10489.855MHz. This has proved so popular that, by the kind permission of AMSAT-DL, from the 4th of February 2024 we’re introducing a second reading at 2100UTC. This will suit our international audience in the western lobe of the footprint. The existing team of three Newsreaders is looking for another volunteer to join them. If you are an RSGB member with a good QO-100 facility and would be interested in broadcasting the news, please contact the GB2RS Manager, Steve, G4HPE at gb2rs.manager@rsgb.org.uk for further details.

During February, the RSGB’s Photo Friday focus on social media is all about clubs. If you’d like your club to be included, let the RSGB comms team know what you've been up to and who's been involved and share all the brilliant things you've been doing. Email comms@rsgb.org.uk by the 31st of January with a brief summary of the activity and some photos, and please make sure that everyone in the photo is happy to have their face on social media!

Chris Deacon, G4IFX has been awarded a PhD from the University of Bath after completing research on propagation. His thesis was entitled: “Radio propagation through ionospheric Sporadic-E”. This part-time work over many years involved looking at Sporadic-E on the 6m band, including making novel measurements of signal amplitude, phase, derived Doppler, polarisation and potential time delay to discover the nature of sporadic-E propagation at VHF frequencies. The RSGB Propagation Studies Committee congratulates Chris on this fantastic achievement. You can find out more by searching for Chris’ name on the University of Bath research portal at researchportal.bath.ac.uk Chris has done a number of presentations about propagation at RSGB Conventions over the years, which you can see on the RSGB YouTube channel at youtube.com/theRSGB

The CQ 160m DX Contest starts at 2200UTC on Friday the 26th and ends at 2200UTC on Sunday the 28th. Using CW on the 160m band, the exchange is signal report and CQ zone. American stations send their state and Canadian stations send their province.

The British Amateur Radio Teledata Group RTTY Sprint starts at 1200UTC on Saturday the 27th and ends at 1200UTC on Sunday the 28th. Using RTTY on the 80 to 10m bands, where contests are permitted, the exchange is a serial number.

The UK Six Metre Group Winter Marathon began on Friday the 1st of December 2023. The contest will run until the 31st of January 2024. Using all modes on the 6m band, the exchange is signal report and locator.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 18th of January 2024

We had yet another week with good solar conditions which, at this point in the cycle, is good news. The solar flux index remained in the 170s to 180s range and the Sun is currently peppered with spots.

The Kp index never got above 3.33 and that was only for one three-hour period on January the 16th.

We were also lucky with solar flares in that we only had minor C-class flares to contend with. An eruption was observed beyond the west limb on January 14th. The event generated a fast-moving coronal mass ejection or CME, but it was directed away from our planet.

Daytime MUFs over 3,000km remain high at more than 28MHz. At night this reduces to around 6.9 to 9.5MHz, meaning only the 40m band is mainly open to DX, if at all.

HF-wise, this is the best time for low-band DXing, such as 40m band contacts with New Zealand around sunrise, and overnight QSOs on the 80m band with the USA.

Other DX being worked by members of CDXC includes XU7AKU in Cambodia on 40m CW in the early evening; V31XX in Belize, VP9KF in Bermuda, on 30m CW around 1000UTC; and E20AX in Thailand on 40m CW around 0930UTC.

Next week, NOAA predicts that the solar flux index may remain in the 160 to 170 range with a maximum Kp index of 2. As always, take that Kp prediction with a pinch of salt as a single Earth-facing coronal mass ejection could send it sky-high with an accompanying lowering of the MUF and generally poor conditions.

And now the VHF and up propagation news from G3YLA and G4BAO

The main theme of the VHF and up propagation options is that we have three distinct phases coming up.

The first phase is set to end today, the 21st. This will be the final blast of the cold northerly wind, which may produce some rain scatter near coasts from snow showers. It is probably not especially useful for Tropo, even inland, except perhaps for local overnight temporary short-distance enhancements due to surface cooling and night frosts.

Phase two is the transition to very unsettled, wet and windy weather, which starts to arrive during this weekend, ending the 21st, and generally sets the pattern for much of the coming week. Maybe it will be a rain scatter option for the GHz bands, but the main radio consideration will be wind potentially damaging antennas, particularly in the south.

Phase three will be the introduction of a weak ridge of high pressure over southern Britain in the second half of the coming week and the following weekend. This could bring some more productive Tropo to southern parts of the UK, especially into the last weekend of the month.

Other propagation modes are available but don’t seem to be elevated beyond chance occurrences for meteor scatter or aurora. There is a vanishingly small chance of Sporadic-E, as we are in the minimum period for this sort of propagation until after Easter.

For EME operators, Moon declination is positive and rising, reaching a maximum on the 23rd. Path losses increase all week until apogee on Monday the 29th. 144MHz sky noise is low to moderate this coming week.

And that’s all from the propagation team this week.

The news headlines:

• RSGB releases new video about changes to amateur radio licensing
• WRTC 2026 team to appear in an RSGB Tonight@8 webinar
• Paul Athersmith, M0PLA achieves Mountain Goat award

Following Ofcom’s consultation on the amateur radio licence last year, it released a statement in December 2023. The statement outlined its decision to update the amateur radio licensing framework to ensure the policies and licences meet the needs of today’s and tomorrow’s radio amateurs while streamlining the licensing process. It also published a General Notice, giving notice of its proposal to vary all amateur radio licences. The RSGB has just released a video in which RSGB General Manager Steve Thomas, M1ACB chats to RSGB Spectrum Forum Chair Murray Niman, G6JYB. Murray recaps some of the headline results of the Ofcom consultation, including where changes have occurred to Ofcom’s proposals. They also talk about what this could mean for radio amateurs in the future. This is a great example of how the RSGB is working not only to defend the spectrum but also to support all radio amateurs to understand and make use of the privileges they enjoy through their amateur radio licence. You can watch this video on the RSGB’s YouTube channel or via the Society’s licence review updates page at rsgb.org/licencereview

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 11th of January 2024

We couldn't have asked for better solar conditions last week. We had a low Kp index that never got any higher than 2.67, and a solar flux index that started the week at 167 and then rose to 186 by Wednesday.

So, at first glance, this looks like ideal conditions for HF. However, we are in the middle of winter and therefore the ionosphere is not at its best. The low bands are also being affected by the higher solar flux and, on the whole, the 14MHz band and above are closing as the night draws in.

Daytime critical frequencies remain around 9 to 10MHz, so the 40m band should remain useful for inter-UK work. Nighttime critical frequencies are currently falling to 3.5 to 4.5MHz, which means the 40m band is only open to long skip, if at all.

The critical frequency is the highest that still returns a signal from the ionosphere if sent straight up, and is a good guide as to which bands are open to near vertical incidence skywave or NVIS signals around the UK.

On the brighter side, 14MHz has been showing signs of DX. The VK6RBP beacon has been heard on 14.100MHz in the afternoon via the short path and 28.200MHz in the morning via the long path.

The 12m band has shown international beacons RR90 in Siberia, OH2B in Finland, LU4AA in Argentina and YV5B in Venezuela, on 24.930MHz in the morning. While the 10m band also highlighted YV5B in Venezuela during mid-morning.

Not a massive catch, but better than we were getting two years ago!

For the coming week, NOAA predicts that the solar flux index may fall into the range of 150 to 165. Geomagnetic conditions are predicted to remain settled with a maximum Kp index of 2.

As always, this could easily change if we have a coronal mass ejection, so keep an eye on solarham.net for near real-time solar conditions.

And now the VHF and up propagation news from G3YLA and G4BAO

The area of high pressure has been working well for some parts of the country, with Tropo conditions lasting into the start of this weekend, but as a cold front moves South on Saturday the 13th, all will change as the high becomes displaced to the Atlantic.

Therefore, there is no significant Tropo for the coming week, but there may be some rain scatter from showers, especially around the coasts.

We seem to have passed the period of unusual winter Sporadic-E propagation without much evidence of activity so that just leaves meteor scatter. After the Quadrantids last week, we entered a period of low meteor shower activity, leaving just random meteors until the next major shower, the Lyrids in April.

For random meteor scatter, the pre-dawn period works best. The solar conditions can still be instrumental in producing extra propagation treats with chance aurora. Probably the best operating policy is to monitor the geomagnetic Kp-index with high values greater than 6 being a good sign for VHF.

For EME operators, this week starts with very low Moon declination, low peak Moon elevation and short Moon windows, but declination is rising and goes positive again on Tuesday. Path losses are still low and reached minimum at perigee on Saturday the 13th. 144MHz sky noise is low for all of the coming week.

And that’s all from the propagation team this week.

GB2RS News

Sunday the 7th of January 2024

The news headlines:

• RSGB Regional Team vacancies
• RSGB volunteer interviewed by the BBC
• RSGB National Radio Centre seeks to expand its team of volunteers

The news team and all the staff at RSGB HQ would like to wish our newsreaders, listeners and online readers a very happy New Year. We would like to remind everyone that we always welcome your news, by email, to radcom@rsgb.org.uk and the deadline is 10 am sharp on Thursday mornings. The GB2RS script is usually uploaded to the RSGB website by 4.30 pm each Friday afternoon.

Are you interested in supporting your local radio amateurs and promoting amateur radio where you live? The RSGB Regional Team has eight Regional Representative vacancies across the UK where you could make a difference. Last year, Regional Reps got involved in a variety of activities including British Science Week and YOTA Month to help spread the word about amateur radio in their regions. If you have the passion to do this, go to the RSGB website at rsgb.org/election to find out how to apply. The deadline for applications is the 31st of January.

It was great to hear RSGB volunteer Peter Marcham, G3YXZ on BBC Radio Oxford on New Year's Day. Peter volunteers at the RSGB National Radio Centre, as well as being a tour guide at Bletchley Park. He spoke to radio presenter Sophie Law about his volunteering after sending the words "Bletchley Park Guide" to a three-word, text-in feature on why listeners were up early on New Year's Day. Search for Sophie Law on BBC Sounds, choose the New Year’s Day programme and listen from 2 hours, 11 minutes, and 25 seconds.

There is so much happening at the RSGB National Radio Centre that it needs to expand its team of volunteers! If you can volunteer on a Friday or Saturday, you will be particularly welcome. The NRC has a fabulous set-up, and full training on using the GB3RS radio station will be given. You should enjoy meeting people and be able to volunteer for one or two days per month as part of a friendly and dedicated team. NRC volunteers also enjoy numerous benefits associated with volunteering at Bletchley Park. For more information, please email NRC Coordinator Martyn Baker, G0GMB via nrc.support@rsgb.org.uk

We have received the sad news that both Mick Senior, G4EFO and Martyn Vincent, G3UKV have become Silent Keys recently. Mick was a former Regional Representative for Region 10, and the keeper of a number of local repeaters. Martyn was the District Representative for Shropshire, North Worcestershire and West Birmingham. Previously, he volunteered for the RSGB as the Regional Representative for Region 5 and as a member of the Nominations Committee. He was also a very well-respected member of the microwave and contesting communities. Our thoughts are with their families at this difficult time.

This year marks 150 years since the birth of Guglielmo Marconi in 1874. The Cornish Radio Amateur Club will be organising International Marconi Day this year on the 27th of April. For more information and updates, visit the GB4IMD Facebook page.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 4th of January 2024

Welcome to the first HF propagation report of 2024 – it looks like it will be business as usual!

A massive X5-class solar flare occurred on the 31st of December. Luckily, this happened at 2155UTC so didn’t affect the ionosphere over the UK. But it did launch a large coronal mass ejection, which was forecast to possibly hit the Earth on the 2nd of January. It looks like it largely missed us, although low-energy proton levels streaming past Earth continued to rise and were at the minor S1 radiation storm threshold on Wednesday the 3rd.

Had active region 3536 been directly facing Earth when the flare was observed, a stronger proton event and geomagnetic storm would have been very likely. Only minor HF signal degradation through the polar zones should be expected because of the minor S1 storm. So, it looks like we dodged the bullet again, but this is a warning that there could be more to come.

Otherwise, the solar flux index declined to the 140s over the Christmas period, although it looks like it may increase over the coming week.

NOAA predicts it could be in the range of 150 to 160 next week, with a maximum Kp index of 3 on Monday the 8th, or Tuesday the 9th. However, this could soon change if we have another solar flare and subsequent coronal mass ejection, which could see the Kp index rise two days later. So, make the most of HF when the Kp index is low!

Otherwise, the winter period is when the low bands, from 160 to 40m, come into their own. While solar maximum is not the best time for low-band propagation, there will still be plenty of DX to be worked. Generally speaking, winter is a good time for east-west paths on HF too.

Taking a closer look at 40 metres, the band should open for DX in an easterly direction during the late afternoon and towards the south at sunset. Paths during the afternoon may also include West Coast USA in mid-winter. Relatively local contacts should be possible during the day, as the critical frequency remains above 7MHz during daylight.

And now the VHF and up propagation news from G3YLA and G4BAO

A new year brings a change of weather type and, after some residual rainfall events at the tail end of the previous week, we should be seeing a marked improvement in the weather as high-pressure returns fairly generally across the country by this first weekend of January, ending today, the 7th.

This will remain near, or very close by, for much of the coming week and into the following weekend. It is good news for Tropo, initially over the North Sea towards southern Scandinavia and the Baltic region, but will probably change to favour the western side of Britain in the second half of the week. This is nice timing to coincide with the 70cm band RSGB contests during the week on Tuesday the 9th and Wednesday the 10th of January.

Up until the middle of the month, we should be alert to rare mid-winter sporadic-E propagation. With a very contorted jet stream pattern during the whole period, the chances are better than average. This is another piece of good timing for the 50MHz UK Activity Contest on Thursday the 11th.

We were going through the Quadrantids meteor shower as this report was being written, so this may provide a little boost to meteor scatter into some of the coming week. Rain scatter will be a rapidly diminishing option during the period as high pressure builds next week. The solar conditions continue to produce elevated Kp index events. So, again, check for auroral openings although, generally, aurora is usually better towards the Spring.

For EME, this week we see a negative Moon declination, falling to a minimum by Wednesday. So, Moon windows will be short and peak Moon elevation will be low. Path losses are also low, but we are still over a week away from perigee, the closest approach of the Moon to the Earth. 144MHz sky noise increases all week culminating in the Sun and Moon being close in the sky on the 11th.

And that’s all from the propagation team this week.

GB2RS News

Sunday the 24th of December 2023

The news headlines:

• Examinations and Syllabus Review Group to update syllabus
• The RSGB election process is underway
• Volunteer Youth Country Representatives sought

Season’s greetings to all our listeners! Today’s GB2RS news script will be the final one of 2023. Today’s news reading is optional, as the RSGB appreciates that not all newsreaders will be available, but the script will be on the RGSB website so all can see it. We’d like to take this opportunity to thank all the newsreaders, who read the news on a variety of platforms, for their service to their fellow amateurs throughout the year. We’d also like to remind amateurs that there has been a long-standing convention to listen for news broadcasts on Sundays before transmitting, to allow news reading to go ahead without interference. Thank you to all those who listen on Sunday mornings, and the other times that the news is read, to those who call in afterwards to speak to the newsreaders, and to everyone who listens via various platforms. Please note, there will be no script prepared for broadcast on Sunday the 31st of December 2023 due to RSGB HQ being closed from 4.30 pm on Friday the 22nd of December until 8.30 am on Tuesday the 2nd of January 2024. Newsreaders may, of course, choose to run a net at their normal transmission time, but under their own callsign only.

Following its consultation on proposed changes to the amateur radio licence, Ofcom has recently published the “General notice of proposal to vary amateur radio licences”. The timescale for putting the licence changes into effect means that the Examinations and Syllabus Review Group has been working on the revised syllabus, version 1.6, in parallel with the Ofcom consultation. To read the full explanation, and see the draft sections, go to the RSGB website at rsgb.org/training and choose the ‘Trainer Information’ link in the righthand menu.

The RSGB election process is underway and the closing date for RSGB Nominated Directors is Wednesday the 3rd of January. In being a Director, you are responsible for taking strategic decisions that steer the direction of the Society and provide leadership and motivation to implement its strategy. If you have the right skills and attributes that you think can help the Society develop for the future, then please get in touch. Contact the Nominations Committee Chair, Bob Beebe, GU4YOX via nomimations.chair@rsgb.org.uk On the RSGB website there is information about the Elected Director and Regional Representative roles available and the process for standing for those roles. You can also read an important statement from Don Beattie G3BJ, former RSGB President and IARU Region 1 Past-President, in which he outlines what he thinks are the necessary skills for Board Directors and encourages people to play their part in the future of the Society. Go to the RSGB website at rsgb.org/election to find out more.

A reminder now that the RSGB is looking for four licensed radio amateurs to help raise the profile of wireless communication amongst young people. Initially, we’re looking for RSGB members based in England, Northern Ireland, Scotland and Wales to engage young people in the hobby. These volunteer Youth Country Representatives will represent the RSGB at externally organised events and will plan and deliver outreach activities. If you have plenty of ideas, a passion for getting young people involved in amateur radio and experience of running small-scale events, we would be very keen to hear from you. For full details of these roles, see rsgb.org/volunteers and for an informal discussion, please email RSGB Board Director, Ben Lloyd, GW4BML at: gw4bml@rsgb.org.uk

If you live in Region 11 you could support your local amateur radio community by becoming an RSGB District Representative. DR111 covers Cornwall and the Scillies, whilst DR114 focuses on Dorset. If you would like to find out more, please contact the Region 11 Regional Representative, Andrew Jenner, G7KNA. There are also District Representative vacancies in Region 3 and Region 10 – find out more on the RSGB website at rsgb.org/volunteers

Two more RSGB Convention presentations will be published on YouTube over the Christmas holidays. In the first, Nobby Styles, G0VJG describes the challenging and hazardous DXpedition to Europe’s rarest IOTA location, Rockall Island.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 21st of December 2023

We filed last week’s GB2RS propagation report and, shortly after, we had the biggest X-ray solar flare event this cycle!

This just shows how hard it is to predict solar activity and why long-term HF predictions are problematic. Anyway, back to the solar flare which occurred at 1702UTC on the 14th of December. This was an X2.8 event that was also responsible for a coronal mass ejection.

Luckily, the Sun had already set in the UK but if you were working the USA, Caribbean or South America on HF, you may have found the path suddenly disrupted. If that did happen to you, please let us know.

The full halo coronal mass ejection, or CME, that followed headed mostly to the west, although a glancing blow was predicted to hit us on the 15th or 16th of December. It eventually hit late on the 17th of December, pushing the Kp index to six on the morning of the 18th of December. HF conditions remained fairly unsettled after that.

Next week, NOAA predicts that the solar flux index will be in the 140 to 150 range again and that the Kp index will be no more than two. However, that geomagnetic prediction may be wishful thinking. There are a lot of sunspots at the moment and active region 3529 may be a strong candidate for flare and CME action over the coming week.

So, our message is: work the DX when you can and don’t ignore the lower bands, such as 40, 80 and 160 metres, which may offer some good DX at night in the middle of winter.

And now the VHF and up propagation news from G3YLA and G4BAO

The weather pattern over the Christmas period is set up as a teaser between very mild, and cold enough for some wintry weather. However, it probably won’t be cold enough – except in the north – to get too excited before the 25th.

To set the scene and give you a chance to ‘roll your own forecasts’ in view of the long lead time for this forecast, the atmosphere is part way through its normal transition from summer-time Atlantic jet streams over Iceland to winter jet streams over the Mediterranean.

We are currently in the middle, and this puts the main jet stream path across the British Isles. It will produce alternating periods of mild and cold weather – very difficult to pin down even a few days ahead, let alone into the New Year!

What we can get from this, in terms of propagation, is a good chance of the meandering jet stream being able to invoke a mid-winter Sporadic-E event for some of us. However, the times are less predictable than in the summer, so just keep a listen out on the 10m and 6m bands for activity, it would be a shame to miss any.

Tropo has done well over the last weekend, so a large high to the south of the UK, over the continent, is worth looking out for especially paths south to Iberia or east to the Baltic.

Lastly, look out for the lesser modes of scatter from rain or meteors, which will continue to be a random option, as well as the potential for aurora.

For EME operators, Moon declination is positive and rising, reaching a maximum on Boxing Day. Path losses are rising to a maximum on New Year’s Day. 144MHz sky noise is moderate all week.

Finally, a big thank you from the propagation team for the 'fine business' effort you all put into getting on the bands to explore and report these exciting propagation modes… Merry Christmas!

And that’s all from the propagation team this week.

GB2RS News

Sunday the 17th of December 2023

The news headlines:

• Ofcom document on changes to amateur radio licensing released
• YOTA month continues
• WRC-23 concludes

Earlier this week, Ofcom released a document titled “Updating the Amateur Radio Licensing Framework”.

Youngsters on the Air month is well underway with some great activity from a range of schools, universities and radio societies. If you’d like to get involved, you can listen out for special callsign GB23YOTA and make these young operators feel welcome on the air. Today, the callsign is being operated between 9 am and 6 pm under the supervision of RSGB Board Director, Ben Lloyd, GW4BML. Young members of the Hereford Amateur Radio Society, and other local youngsters, will be getting on the air. Later this week, on Thursday the 21st of December between 6 pm and midnight, Ben will also be helping a fully licensed young radio amateur activate a SOTA summit. They will be working the 160m and 80m bands with the YOTA callsign. On Saturday the 23rd of December, Tommy M7OMY, supervised by M0BOY, will be back on the air for the duration of the day and night. There is still time to get involved with Youngsters on the Air month – just email Jamie, M0SDV at yota.month@rsgb.org.uk to book a slot or ask for further information.

Following four weeks of deliberations, the 2023 World Radiocommunication Conference concluded in Dubai on Friday the 15th of December with the signing of the ‘Provisional Final Acts’ and a closing ceremony. The numerous changes don’t formally take effect until the 1st of January 2025 and preparations are already underway to agree the agenda for future WRC events. The RSGB’s special focus pages have the final news report and photos. To view these, visit rsgb.org/wrc-23 The results will be reviewed by the Spectrum Forum after the Christmas break, alongside IARU and domestic changes.

The UK Meteor Beacon project is now in its second phase, and both phases have been supported by the RSGB Legacy Fund. At the RSGB 2023 Convention, Brian Coleman, G4NNS outlined the plan for the second phase. A network of receivers will be developed, streaming their data via a central server for detailed study of individual meteor events. This is a cooperation between the ‘worlds’ of amateur radio and astronomy. You can now watch Brian’s presentation on the RSGB YouTube channel at youtube.com/theRSGB The RSGB Legacy Fund supports a wide range of amateur radio projects. You can find out more and download an application form on the RSGB website at rsgb.org/legacy

The RSGB election process has begun and there are eleven roles to fill. These include eight Regional Representatives covering a wide range of regions, as well as an elected Director and two Nominated Directors. Bob Beebe, GU4YOX is the new Chair of the Nominations Committee and he is keen to see people volunteer. He says that being a Director of the RSGB is a great opportunity to contribute to the future direction of the Society and the RSGB needs the best people to come forward to play their part. If you don’t feel you can volunteer, do you know someone who would make a good Director? Do you know someone committed to amateur radio, in touch with the leading thinking in amateur radio today, and capable of contributing to the Society’s work in a team environment? If so, ask them to stand for election or as a Nominated Director. Find out more about the RSGB election process, and all the available roles, on the RSGB website at rsgb.org/election

Following feedback from the amateur radio community, the RSGB’s Learning Team is launching a revised Discovery Scheme in the New Year. This will be a revamp of the Individual Scheme from the Beyond Exams initiative and consists of three levels of participation. The ‘Explorer’ level is aimed at newcomers to amateur radio and will run from January to March 2024. The ‘Adventurer’ level, which will run from April to June 2024, is targeted at those who have been involved with amateur radio for a while and wish to progress. Requiring more significant experience, the ‘Master’ level will run from July to December 2024. For more information, contact Beyond Exams Coordinator Mark Burrows, 2E0SBM​ via be.coordinator@rsgb.org.uk

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 14th of December 2023

We had a fairly settled time last week with only the solar wind and some solar flare activity to contend with.

Sunspot region 3514 produced a moderately strong M5.8 solar flare on the 14th of December. This event was responsible for a coronal mass ejection, or CME, but that was directed to the west and missed the Earth.

The problem with the solar wind is that its Bz has mostly been pointing south, which means it more easily couples with the Earth’s magnetic field allowing solar plasma to flood in. The result was that the Kp index mostly remained high, with the index hitting three or four across the midweek period.

While not excessive, this has affected HF to an extent, although the daytime MUF over 3,000km has remained above 28MHz on most days.

What you may find is that the higher bands are now closed until later in the morning and that they close earlier in the afternoon as well. This is partly due to the time of year and partly due to the lower solar flux index we are experiencing.

The solar flux index improved slightly over the past week, ending at 135 on Thursday, having been in the 120s earlier.

Next week NOAA predicts that the solar flux index will be in the range of 125 to 140. It is predicting unsettled geomagnetic conditions from the 16th to the 19th of December, with a maximum Kp index of five.

Now for a propagation forecast. Santa’s broadcasting arm, Santa Radio OF9X, is active again from near the Arctic Circle on all amateur radio bands, using CW, SSB and FT8, until the end of the year. The activity is organised by the Radio Club of Pusula, OH9W and Radio Arcala, OH8X.

Keep an eye on DXSummit.fi to find out where they are operating. So far, they have been spotted on the 160, 40, 20, 12 and 10m bands. The Proppy prediction chart shows that anywhere between 10MHz and 28MHz is fair game during daylight, while 7MHz and below will work better at night.

And now the VHF and up propagation news from G3YLA and G4BAO

As expected, the return of a significant region of high pressure developing over the continent as this week ends will bring some enhanced Tropo conditions from the southern UK into the continent and across Biscay to northern Spain.

It is also possible that the traditionally preferred policy of beaming around the edge of a high for DX paths will make looking east into northern Germany, Poland and the Baltic a fair prospect, but only until around Tuesday the 19th when a cold front moves south and breaks the path. This is a pity since it will be before Tuesday’s 1.3GHz Contest and Thursday’s 70MHz UK Activity Contest, which look like missing the best conditions.

The second half of the coming week will be dominated by low pressure to the north of Britain and a series of fronts and showery troughs driving south, bringing much colder air with a risk of wintry weather. It will also become very windy at times.

This removes Tropo from the picture, but rain scatter may be worth considering, although the shower echo regions will be moving briskly. Use online rain radar displays to help you.

The other modes of meteor scatter and aurora are worth leaving on the list with the remains of the December Geminids still with us.

Don’t forget that out-of-season Sporadic-E propagation often appears in the period from mid-December to mid-January, so check the 10 and 6m bands periodically for activity.

For EME operators, Moon declination is negative but rising, going positive on Wednesday the 20th. Path losses are at a minimum at perigee, the Moon’s closest point – this was on Saturday the 16th. 144MHz sky noise is low all week.

And that’s all from the propagation team this week.

The news headlines:

• 23cm recommendation approved at WRC-23
• RSGB Examinations Standards Committee report published
• RSGB Elections process begins

The third week of the WRC-23 World Radiocommunication Conference has seen the approval of a new footnote to the 23cm amateur band at 1240 to 1300MHz under Agenda Item 9.1-b. This draws attention to the recently released ITU-R Recommendation 2164 that provides guidance to avoid interference to radio navigation satellite services, or RNSS, such as Galileo. This is a major landmark after four years of hard work which started after WRC-19 and now lays out the basis for guidance and next steps. IARU President Tim Ellam, VE6SH said that the addition of a footnote that provides guidance to administrations in the event of interference to the RNSS is a good regulatory outcome for amateurs and the primary users of this band. You can read more on this story at tinyurl.com/RecRNSS The IARU team continues its work on other WRC issues including the development of agendas for future conferences.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 7th of December 2023

We dodged a bullet last week as a high-speed solar wind stream from a coronal hole sped past the Earth. Although the wind speed was often in excess of 600 kilometres per second, its Bz, or magnetic field, was pointing north. The net result was that most of this passed harmlessly away from Earth and the Kp index remained around three.

Meanwhile, the solar flux index declined to 130 by Thursday, which is quite a difference from the 194 we had on the 23rd of November.

Solar activity last week reached moderate levels thanks to multiple low-level M-class solar flares detected around active region 3513 in the northeast quadrant. This region also produced frequent C-class flares.

Daytime MUFs over a 3,000km path mostly remained over 28MHz, while nighttime MUFs over a similar path length remained around 10MHz.

As we head towards mid-winter, we may expect these nighttime MUFs to drop, with the result that the 80m band closes down for short-skip early on in the evening – the curse of the inter-UK 80m Club Championship contests!

However, the 80m band may still be open over long distances and we are now entering the best time of year for low-band DXing. Keep an eye on the top end of the 80m band, around sunrise, for transatlantic signals.

Next week NOAA predicts that the solar flux index may recover a little and be in the range of 130 to 150. Geomagnetic conditions will depend upon coronal mass ejections but are predicted to be good, with a peak of Kp4 on the 12th of November. There is a slender coronal hole on the Sun that could cause the Kp index to rise this weekend, ending the 10th, due to its associated solar wind stream. However, it shouldn’t be too bad and any poor HF conditions are likely to be short-lived.

Finally, NOAA has updated its progression forecast for Solar Cycle 25. It now predicts that this cycle will peak somewhere between January and September 2024 with a solar flux index of around 167 to 201.

And now the VHF and up propagation news from G3YLA and G4BAO

The present spell of unsettled weather at the end of the first week of December will run into the first half of next week.

This brings a limited chance of rain scatter on the GHz bands, but there is a strong signal in the models for a major change of weather patterns for the middle of next week.

This will be the arrival of high pressure around Wednesday the 13th that will probably last into the following weekend, although there is some model variation in how quickly it will move away.

The main result is that, although it begins as a cold air with high pressure with frosts, it will probably develop surface temperature inversions, which will be useful for Tropo. Towards the end of next week, as the centre of the high drifts east, it will allow more moist air at the surface and produce stronger ducting potential as well as develop an upper-level inversion for longer DX paths into the continent.

The evening of the 14th of December sees the peak of the biggest and most reliable meteor shower of the year. The Geminids have the potential for a zenithal hourly rate of 150. The higher 50MHz and 144MHz activity usually provide the best chances, and a reasonably quiet QTH with 100W and a beam will bring you plenty of digimode QSOs.

QSOs are even made by EME-class stations on the 70cm band and strong, long reflections on the lower bands can allow SSB QSOs if you’re persistent enough.

That said, MSK144 and FSK441 digimodes will be the most reliable.

Aurora remains a possibility, but the isolated out-of-season sporadic-E blips on the Propquest NVIS plots last month have quietened down for now.

For EME operators, Moon declination is negative, falling further and reaching its minimum on Thursday the 14th. Path losses are falling towards a minimum at perigee on Saturday the 16th. 144MHz sky noise is moderate until the 12th and 13th when the Moon and Sun are close in the sky.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 7th of September 2023

The propagation team was caught out last week by two coronal mass ejections, or CMEs, that came off the edge of the Sun. The arrival of those CMEs on the 3rd of September eventually pushed the Kp index to 5.67.

In its report, Spaceweather.com said that it was possible that a CME arrived on the 2nd of September, but its weak impact was masked by a chaotic stream of solar wind already blowing around Earth at the time.

At this time of year, even weak CMEs can do a good job of sparking auroras as a result of the Russell-McPherron effect, which boosts geomagnetic activity around the equinoxes.

So much for saying that we could expect quiet geomagnetic conditions last week!

The Solar Flux Index declined to 131 but has since recovered to reach 147 on Thursday the 7th, with eight active regions visible. We had a number of M-class solar flares last week, but nothing too damaging.

With the Kp index back to one on the 7th, we saw daytime MUFs rising again, heading above 24.9MHz over a 3,000km path. There were lots of Chinese and Japanese stations on 21MHz FT8 around 1100UTC on Thursday. And up on 12m FT8, even more of the same. DX stations included Thomas, KH0/KC0W on the Mariana Islands in the Pacific.

While the 10m band was just about open as well, it offered slim pickings compared with the 12m band.

Next week NOAA predicts that the Solar Flux Index will increase over the week to hit perhaps 155 by next weekend. Geomagnetic conditions remain variable with a Kp index of three or four forecast for the 12th to the 16th.

This weekend the geomagnetic forecast is that it will be quiet although, with so many sunspots visible at the moment, it wouldn’t take much for a CME to disrupt things. As always, keep an eye on solarham.net for near real-time updates.

And now the VHF and up propagation news

The RSGB 144MHz Trophy produced good DX on 2m into Poland and Sweden, so we guess that Tropo performed for us this week.

This spell of hot sunny weather, due to high pressure, does mean Tropo was the mode of choice for the end of this current week, ending today the 10th, especially across the North Sea.

However, unsettled weather is gradually encroaching from the west, introducing some thundery rain into western areas, and this will spread east.

Although the Tropo will cease, Gigahertz bands rain scatter is a likely replacement although very isolated rather than the widespread nature of a good Tropo event. It should be noted that next week is not fully determined by all models with quite a spread of outcomes. Either way, it's Tropo or rain scatter for most areas next week.

It’s always possible that meteor scatter and aurora could show during this period. The early morning, around dawn, is usually the best time to look for random meteor scatter activity in the absence of any major meteor showers. For aurora, it’s best to follow the solar data from spaceweather.com to pick up early alerts and an increasing Kp index.

For EME stations, Moon declination is at its highest this weekend but with apogee, the Moon’s furthest point from Earth, next Tuesday, path losses are high. 144MHz sky noise is low for most of the week except for Thursday and Friday when the Moon and Sun are very close, meaning high solar noise in the beamwidth of antennas.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 31st of August 2023

We had another week of relatively settled solar conditions. The Kp Index never really got above three and the Solar Flux Index flattened to be below 140. Solar flares were nominal with only minor C-class events occurring and with no Earth-directed coronal mass ejections.

The solar wind speed remains low as does its density. The all-important Bz has headed south at times meaning it more easily couples to the Earth’s magnetic field, but the solar wind’s low speed and density means we have not suffered from geomagnetic disturbances.

As a result, ionospheric conditions were quite good with much DX romping in on 21MHz, including Mongolia on FT8 during the afternoon.

On the 10m band Vlad, 9Q2WX in the Democratic Republic of the Congo, and Robert, 9N7AA in Nepal, were both logged around lunchtime on CW. At the same time, Ravi, S79VU in the Seychelles could be heard on SSB.

The Chilton and Fairford Digisondes remain down, but Dourbes remains online which is still driving propquest.co.uk

Daytime maximum useable frequencies over a 3,000km path are currently peaking above 28MHz at times, although you may find 21 and 24MHz more usable. Daytime critical frequencies remain above 7MHz making the 40m band very useful around the UK.

Next week, NOAA predicts that the Solar Flux Index will remain in the range of 140 to156. Geomagnetic conditions are predicted to be quiet, apart from an excursion between September the 6th to the 8th when the Kp index could rise to three.

And now the VHF and up propagation news

There will be some GHz bands rain scatter on offer as we end this current week, but it’s ‘all change’ by the weekend. The prospects for VHF and UHF, then, are looking very promising indeed, especially good for those out working portable in the 144MHz Trophy Contest today, the 3rd of September.

After lots of uncertainty in the forecast during the last week, there is now plenty of support from the models that the high-pressure version is the favoured outcome. This should be very encouraging for 2m band contesters hoping to get some enhanced Tropo propagation.

Paths across the southern North Sea to Denmark and southern Sweden look good throughout. It would also be worth looking to the south across the Channel and, for some southwestern parts of the UK, down across Biscay to Spain.

There are two very useful websites that detail the expected Tropo prospects using the weather forecast model data to calculate the vertical changes in the refractive index of the air and hence Tropo. These are dxinfocentre.com and tropo.f5len.org

Remember that Tropo improves as you move from HF to 2m, to 70cm and 23cm. So, give CW or SSB a try and don’t just stay on FT8 or over-crowded repeater channels during lift conditions. These enhanced Tropo conditions will likely extend well into next week, but with a chance of low pressure bringing unsettled weather back to the south by the end of next week.

The daily Sporadic-E blogs have finished for this year, but the jet stream charts will still be available on propquest.co.uk and of course, random meteor scatter and chance aurora are still there if you are lucky.

For EME stations, Moon declination is positive again but reaches maximum late at night initially moving to early morning as the week progresses. Last Wednesday’s perigee means path losses are still low but increasing daily. 144MHz sky noise is low, rising to moderate by next weekend.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 24th of August 2023

Last week saw plenty of DX being worked, thanks to quiet geomagnetic conditions and a seasonal change to a more autumnal ionosphere.

Although we are still in August, there are signs that the ionosphere is moving away from its summer doldrums as its chemical composition changes to more monatomic species, which ionise more easily.

Another bonus is that there has been a big reduction in the size and number of coronal holes on the Sun, which again leads to lower Kp indices.

Mike, G8AXA reports that, for the first time in a long while, his Faros IBP beacon monitoring software recorded the VK6RBP beacon on 28.200MHz between 0857 and 1000UTC, via short path, just making S1 on his long wire and Yaesu FT-991A. On 21.150MHz, he also recorded hearing the ZL6B beacon between 0757 and 0909UTC up to S3.

Conditions should continue to improve as we move towards September and October.

Last week, the solar flux was in the 140s and 150s. The Kp index never rose above three, meaning the ionosphere was quite stable. The proton flux was also very low. FT8 on the 15m band was humming in the afternoon with the Far East and Caribbean both being workable at the same time.

Next week we have active regions 3413 and 3415 rotating to be more Earth-centric. NOAA predicts that the Solar Flux Index will rise to the 160s again and the quiet geomagnetic conditions may continue with a predicted Kp index of two.

So, as long as we don’t get any solar flares, or CMEs erupting from sunspot groups 3413 and 3415, we could have a good week again for HF DX.

And now the VHF and up propagation news

The current spell of unsettled weather looks likely to stay with us for most of next week, in fact until around Friday when there are signs of a ridge building in for next weekend, although mainly for southern areas.

This could be in time for some Tropo over the weekend of the 144MHz Trophy Contest. However, the models are a bit uncertain this far out, so keep a watch for changes during the week.

The remaining mode in such unsettled weather is of course rain scatter and most of the period until the end of the week should provide many opportunities.

As we approach the close of the traditional Sporadic-E season, although it can still occur in any month, the activity levels are much reduced after the end of August and certainly tail off sharply after the first week in September. We are still getting the occasional flurry of activity for multi-hop paths on 10m to the Far East and the States, so don’t abandon it just yet.

Remaining modes such as meteor scatter are still available via random meteor activity and there are always chances of a higher Kp index with its implications for aurora. Note that the autumn and spring months are typically a preferred time for aurora.

This Saturday sees minimum Moon declination with the Moon not getting above 10 degrees elevation. It goes positive again next Friday. As the Moon’s perigee is on Wednesday, path losses are at their lowest. 144MHz sky noise is high this weekend, but falling to low levels by next Friday.

And that’s all from the propagation team this week.

Now the contest news

On Tuesday the 22nd of August, the SHF UK Activity Contest runs from 1830 to 2130UTC. Using all modes on 2.3 to 10GHz frequencies, the exchange is signal report, serial number and locator.

Next weekend, the CQ RTTYops Worldwide RTTY Contest has two sessions between the 25th and 27th of August. The first session is between 2200UTC on the 25th and 1200UTC on the 26th. The second session is from 1200 to 2359UTC on Sunday the 27th. Using RTTY only on the 160 to 10m bands, where contests are permitted, the exchange is a signal report and the four-digit year of your first licence.

The Worldwide Digi DX contest runs from 1200UTC on the 26th to 1200UTC on the 27th of August. Using FT4 and FT8 on the 160 to 10m bands, where contests are permitted, the exchange is your four-character locator.

Next Sunday, the 27th, the UK Microwave Group 5.7 and 10GHz Contest runs from 0600 to 1800UTC. Using all modes on 5.7 and 10GHz frequencies, the exchange is signal report, serial number and locator.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 17th of August 2023

Sunspot activity continues as we head towards the solar maximum. We have had a reasonably settled Sun over the past week. The Kp index never exceeded 3.33 and was generally in the ones and twos all week. We also had no M- or X-class flares to worry about with only minor C-class events occurring.

The solar flux index stayed in the 140s and 150s, only topping out at 160 on Wednesday and Thursday.

So, it was not a bad week for HF propagation as we head towards the end of August.

There are signs that propagation is improving due to the seasonal change in the chemistry of the F2 layer. With a move towards more monoatomic species and fewer diatomic ones, it means that it is becoming easier to ionise.

Daytime critical frequencies are currently around 6 to 7MHz according to the Dourbes Digisonde, giving a maximum usable frequency over 3,000km of between 18 and 21MHz. 28MHz Sporadic-E contacts have all but finished, but don’t write the 10m band off as you may get the odd surprise.

20m still seems to be the best DX band this week, according to the Chiltern DX Club, with 17 and 15m also contributing.

FO/F4FJH in French Polynesia; E51JD in the South Cook Islands; and FH4VVK in Mayotte have all been heard on 20m SSB, while 3D2AG in Fiji has been worked on 15m CW.

And now the VHF and up propagation news

The fine summer-like weather has returned, at least for this weekend and up to about mid-week before it becomes more unsettled again. So, Tropo will be worth exploring, especially this weekend and during the first part of next week.

Note that, in these warmer summer months, Tropo is often better overnight and early morning, especially those misty ones, but tends to decay as the ground warms in the morning sunshine. However, coastal paths often remain good throughout the day so Tropo paths across the North Sea or English Channel could be worth a look from your holiday deck chair!

The Sporadic-E season is slowly coming to a close, but it is still worth a check in the evening tea-time activity window to make sure nothing is missed, and even better if you can add a morning check-up at around 1030UTC.

The recent Perseids meteor shower may have added some useful meteor debris as fuel, so it is certainly not time to give up checking just yet. However, you may have to manage your expectations on the higher VHF bands.

Meteor scatter is still a good bet in the tail end of the Perseids shower and the usual random meteors increase around dawn. Rain scatter is always an option in the summer months so keep a watch on weather radar displays for the brighter thundery rainfall echoes, especially later next week.

There have been some interesting propagation on 50MHz down to the equatorial belt in the late evenings with D2UY in Angola working FT8 stations in an arc from the Canaries around through Northern Scotland, and the whole of the UK to Turkey with ‘Trans-equatorial sounding’ fading patterns, making decodes difficult sometimes.

Moon declination goes negative again this Sunday, shortening Moon visibility windows and, as we are past apogee, path losses will fall all week. 144MHz sky noise is low to moderate until next Friday peaking at 2900 Kelvin on Saturday morning.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 10th of August 2023

Sunspot activity continues as we head towards the solar maximum. Or have we already gone past that point? Identifying solar maximum can only really be done in retrospect. That is after we have already had it!

Solar maximum is now forecast for early to mid-2025 so we still have some way to go.

Last week the Solar Flux Index declined from 176 on the 5th, to 153 on the 10th.

Geomagnetic conditions were mainly settled, other than a Kp index of 6.67 on the 5th. This was due to an incoming plasma cloud from a coronal mass ejection, or CME, that left the Sun on the 2nd of August.

We had not one, but two X-class flare events recently. These occurred on the 5th and the 7th. The event on the 5th was long in duration with a peak flux at 2221UTC. Luckily it was from active region 3386, which was right on the edge of the visible solar disk, so any associated CME was directed away from Earth.

The second event at 2046UTC on the 7th was also from AR3386, which by now had rotated just out of view of the Earth, so again its associated CME was not Earth-directed.

So, we were lucky on both counts. If this sunspot region is still active on its return, we could be in for a rough ride. Keep an eye out from around the 20th of this month when it should reappear.

HF conditions have been variable, with occasional F2-layer openings on the 10m band. The 15m band has produced some good DX including 5W1SA in Samoa on FT8. The 17m band produced Roland, TR8CR in Gabon on CW for Laurie, G3UML. S79KW in Seychelles was worked by Hugh, EI2HI on 10m SSB, but it has otherwise been quite quiet. Expect more HF DX activity later next month.

Next week, NOAA predicts that the Solar Flux Index will be in the low 160s, with a maximum Kp index of two. If that does pan out, we can expect fairly good HF conditions.

But as always, watch out for solar flares and CMEs that can’t be predicted terribly well. A solar flare could result in a sudden ionospheric disturbance but that would be relatively short-lived. A CME, which might follow a flare in about two days, could see the MUF drop for a day or more.

And now the VHF and up propagation news

The brief period of high pressure around the middle of last week will be long gone by the weekend and new Atlantic lows will again dominate the UK weather. At first, this will be mainly over the northern half of Britain before moving to the western side of the country later in the week.

This means that any Tropo at the end of the previous week is not here to stay. The low-pressure input will bring rain scatter propagation modes and, since we are supposedly in the summertime, the rainfall events may be quite heavy or even thundery in places, so there may be good scattering for the GHz bands.

The Sporadic-E season is still simmering with a few brief moments of single hop within Europe, but also some longer multi-hop paths including to the Far East and VK on 10m.

The upper air pattern of jet streams may still be able to trigger a few openings during the coming week, although it is looking much weaker than last week and possibly mainly biased towards northern areas like the Baltic and Scandinavia.

Meteor scatter is one mode that should do well, especially at first with the peak of the Perseids this weekend. It can be quite interesting to monitor the 2m meteor scatter calling channel and stand outside watching for meteors, especially if it’s a bit warmer! The shower has a broad peak so should still provide activity during the coming week.

Lastly, the Sun continues to offer occasional disturbed conditions with a chance of high Kp indices and possible aurora. The easiest solution is to monitor the Kp index and perhaps your favourite Scottish beacon for signs of auroral flutter.

With the Moon at maximum declination this weekend, with long Moon visibility windows, it's the Microwave EME contest. Moon apogee is next Wednesday so path losses are at their highest until then. 144MHz sky noise is moderate until late Tuesday when the Sun and the Moon are close in the sky until Thursday when levels drop back to low.

And that’s all from the propagation team this week.

• Tonight@8 events on Ofcom consultation
• YOTA summer camp in Hungary
• RSGB coding resources and activities

A reminder that the second of the RSGB’s special Tonight@8 events on the Ofcom Consultation will take place on Monday the 7th of August. This time the focus will be on Foundation and Intermediate topics including callsign and exam changes, as well as the Consultation clauses that might lead to new opportunities for outreach activities for everyone. The Consultation also affects anyone who isn’t currently licensed but is thinking about taking their exams in the next couple of years. After a short introduction, a panel of RSGB experts will answer your questions on this important Ofcom Consultation. For this event, you can submit a question in advance by 6pm today, Sunday the 6th of August. Send a brief question with your name and callsign to comms@rsgb.org.uk You can also ask a question on the night via the live chat. This is an important event – do join it live on Monday via the RSGB YouTube channel. To find out more about the Consultation and this event go to the RSGB website at rsgb.org/licencereview You can watch a recording of the first Tonight@8 event on the Ofcom Consultation via the RSGB’s YouTube channel.

The 2023 Youngsters on the Air, or YOTA, summer camp in Hungary began this weekend and lasts for a week. The four young people representing the RSGB are Alexander Du Rose, 2E0FMZ who is the Team Leader; Henry-James Robinson, M7HJR; Hannah Lee, M7YYQ; and Jake Saul, M7JNS. Each day, they will be sharing news of the activities they enjoy and the amateur radio skills they learn. Take a look at their updates over the coming week on the RSGB website at rsgb.org/yota-hungary and read their fuller report in the October issue of RadCom.

As part of the RSGB’s commitment to encourage youngsters into amateur radio and to support lifelong learning, the Society is providing resources and creating coding activities for people to get involved in throughout the month of September 2023. From the BBC Micro:bit to Node-RED and GNU Radio, there are some great activities you could try yourself with your club or arrange at a local school or community group. If you are an experienced coder, the Society would like you to support this initiative by passing on your enthusiasm to a local school or STEM club with the help of the suggested activities. If you are new to coding and have no idea what Python is or a Raspberry Pi, then the activities will set you on the path of discovery! Find out more on the RSGB website at rsgb.org/coding. If you would like to get involved, contact ESRG member John Hislop, G7OHO via g7oho@rsgb.org.uk

The RSGB has responded to an Ofcom consultation on licensing Enhanced Long-Range Navigation, or eLoran, systems. This would use a new network of 400kW EIRP transmissions at around 90 to 110kHz to provide an alternative to GPS for Position, Navigation and Timing, or PNT. The response, which can be found on the RSGB’s Spectrum Forum webpages, focussed on the high levels of out-of-band emissions that would affect the weak signal 136kHz amateur allocation, as well as transparency on transmitter licensing. The consultation response can be viewed by visiting thersgb.org/go/sfpapers

The ARRL, the national association for amateur radio in the USA, has filed comments against a proposal that would introduce high-power digital communications to the shortwave spectrum that, in many instances, is immediately adjacent to the amateur HF bands.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 3rd of August 2023

The Sun continued to be very active over the last week with a large number of sunspots, numerous C- and M-class flares, and a coronal mass ejection or two.

A coronal mass ejection is predicted to hit Earth this weekend, which could see the Kp index rise, but this is not expected to be too extensive.

Active region 3380 expanded in both size and magnetic complexity, firing off numerous solar flares. Luckily it is now rotating out of view so is no longer a threat.

The Solar Flux Index remained above 170 all week with a sunspot number of 135 on Thursday. Don’t forget that this doesn’t mean there were 135 sunspots, as each group counts ten towards the total. Three sunspots in three groups equals thirty plus three, or thirty-three.

Geomagnetic conditions were mixed with one period giving a Kp index of four, and many when it was over three.

The main DX being chased this week wasn’t actually too far away. The 1A0C station at the Sovereign Military Order of Malta, which confusingly is actually in Rome, gave amateurs plenty of opportunity to add to their band slot totals. The station was raising money for humanitarian charitable projects and was easy to work from the UK.

Next week NOAA’s Space Weather Prediction Centre thinks the Solar Flux Index will remain in the 165 to 170 region. The Kp index shouldn’t rise above three, although that rather depends on whether we have any coronal mass ejections.

There are also signs that we are starting to leave the Summer HF doldrums. MUFs over a 3,000km path have occasionally gone over 28MHz at times. But we are still a long way from Autumn HF conditions, despite the weather!

And now the VHF and up propagation news

The unsettled weather is here for a little longer, but there may be an end in sight as we move through the second half of next week.

To begin, there will be areas of low pressure in control bringing rain or showers and more rain scatter on the GHz bands.

Midweek, the high edges in from the west and remains close to the southeast into the next weekend, but lows and weather fronts will probably return to the western areas by the end of the week. Nonetheless, this should be a period of Tropo for many areas, if only temporarily for western areas.

Meteor scatter could be good with a steady advance towards the peak of the Perseids on the 12th and 13th of August. It might even be warm enough to stand outside in the southeast and listen to the pings while watching the evening sky for meteor trails!

Aurora can’t be discounted either should the Kp index show higher values than, say, 5 and there have been a number of auroral contacts reported by Nordic stations over the last week.

In August there is still some Sporadic-E to be had as luckily the jet stream pattern is still quite busy giving ample triggers for Sporadic-E due to the turbulence they create. As often mentioned, a good time to check, if you are a busy person, is around teatime or late afternoon.

Moon declination goes positive on Saturday so Moon visibility windows will lengthen throughout the week. We are past perigee so path losses are rising again. 144MHz sky noise is low but rising, reaching moderate levels next weekend.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 27th of July 2023 It was a mixed bag last week with periods of settled conditions, but two periods when the Kp index was above four. These unsettled geomagnetic conditions impacted HF, subduing signals and generally not helping at all. The cause was a coronal mass ejection, or CME, that passed Earth late on Tuesday the 25th of July. This triggered a minor G1 geomagnetic storm with the solar wind speed above 500km/s and the Bz component of the interplanetary magnetic field pointing south. By the early hours of Thursday morning, the Kp index was down to 2.33, but there was talk of another CME threatening to push it up again. We ‘dodged a bullet’ on the 24th of July when a large halo CME was observed leaving the Sun. It was so powerful that, despite taking place on the other side of the Sun, energetic proton levels streamed past Earth. By Wednesday lunchtime things were back to normal. By Thursday there were ten active regions visible on the Sun, with a solar flux of 167. Daytime HF conditions are still relatively poor, although the evenings are beginning to show an improvement. We probably won’t see a return to excellent HF conditions until September or October. Having said that, at 1230UTC on Thursday, there were openings on 15m FT8 to Japan, Australia, Indonesia, Puerto Rico, Cuba and Anguilla, despite the predicted MUF over 3,000km being around 19MHz. In other words, make sure you actually listen to the bands! Next week NOAA predicts that the Solar Flux Index will be in the range of 155 to 170. The Kp index is forecast to be around two. There may be a blip on Wednesday the 3rd of August when it is forecast to rise to three. As always, this is likely to change if we get more solar flares and associated CMEs. And now the VHF and up propagation news The coming week is likely to continue its unsettled theme although, unlike last week, this time we may find a temporary ridge of high pressure building over southern England at the end of the week. It’s some way off and much could change before we get there, but there is a hint of some Tropo next Friday, perhaps lasting into the Saturday afternoon for the 144MHz Low Power Contest. The rest of this week and much of next will, however, stay firmly in the unsettled pattern with just rain scatter to console us. The Sporadic-E season often provides activity on the 6m band into the first week of September, so plenty of time to look for those chance QSOs. Last week saw a huge opening to Japan and a smaller opening to North America so there is still plenty to look for. The current spell of unsettled weather is driven by a strong jet stream across the Atlantic into northern Europe and maybe a positive sign for Sporadic-E paths that cross it, say to Iberia, round through Italy to the Balkans. Other modes are relatively-low probability when compared with Sporadic-E, but the disturbed solar conditions could make Aurora a contender on those occasions when the Kp index is above five. Meteor scatter activity continues to increase as we head into the August Perseids, which peak around the 12th and 13th of August. The Moon reaches minimum declination on Sunday, becoming positive again late next Saturday so there will be short Moon windows early in the week. Perigee is on Wednesday so path losses are low. 144MHz sky noise is high this coming weekend turning low late Monday.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 20th of July 2023

The Sun continues to be peppered with spots with a solar flux index of 189 on Thursday the 20th. However, sunspots can bring solar flares and Coronal Mass Ejections, or CMEs, which can be detrimental to good HF conditions.

We have been relatively lucky over the last week as the flares have mostly been minor C-class and a few M-class events. There have been no X-class flares, so ionospheric disturbances have been minor.

A large CME observed from active region 3363 is expected to mostly miss our planet. But the edge of the plasma cloud was still forecast to deliver a glancing blow to our geomagnetic field on Thursday the 20th of July.

A Polar Cap Absorption, or PCA, event was also in progress from the morning of Monday the 17th of July. This was caused by the proton flux rapidly increasing and affecting HF paths over the poles. The proton flux is gradually decreasing but may still have a detrimental effect for a while yet.

Region 3363, which was massive, has now disappeared behind the southwest limb and will no longer be a threat. That is, at least until its return in about two weeks’ time. It will be interesting to see how big it is on its return.

Other than the Kp index hitting 4.67 on the 16th and 17th, geomagnetic conditions have been quiet with the Kp index at one or two over the past few days, which means HF conditions have been quite good.

Daytime MUFs over a 3,000km path have been consistently above 18MHz and often above 21MHz at times. Nighttime MUFs over the same path have been higher than 14MHz, and often 18MHz, at least during the first part of the night.

This means that if you hear signals on 24 or 28MHz the likelihood is that they are due to Sporadic-E propagation.

Next week NOAA predicts that the Solar Flux Index will remain at about 160 to 170. It is also predicting a Kp index of two all week. If that happens, we can probably expect good HF conditions for this time of year. However, with this many sunspots, there is always the strong risk of solar flares and CMEs. So, keep an eye on solarham.net for real-time conditions.

And now the VHF and up propagation news

The continuing spell of unsettled weather will stay with us for the coming week, so any signs of Tropo will be very limited indeed. This means that rain scatter will once again be a predominant propagation mode for those equipped on the GHz bands to use it.

Higher temperatures in summer mean strong convective cells, like thunderstorms, and better reflectivity from the larger raindrops, which can be held aloft by the stronger updrafts in the storm clouds. The reflectivity depends upon the 6th power of the diameter of the raindrop and the number of drops in the beam, so even a small increase in drop size gives a big increase in reflectivity.

Sporadic-E remains in play for a good while yet, so stay alert to cluster reports and, in particular, 10m and 6m beacons. If time is limited, check 1600 to 1700UTC to gain maximum benefit.

The usual other modes are still possibilities, of course. Starting with Aurora, in view of the recently disturbed solar conditions, you should monitor the Kp index for large values above say Kp=5.

Secondly, the Perseids meteor shower will peak between the 12th and 13th of August, but evidence of meteor material from the Perseids is already appearing.

Officially, the shower starts to appear from around the 17th of July. The 50MHz and 144MHz bands have already produced some very short-lived bursts of FT8 signals that may be due to meteors.

The Delta Aquariids may also be responsible for these very sporadic bursts. As we move towards the Perseids peak you should expect an increasing number of bursts.

As the Moon begins its monthly descent towards minimum declination on the 29th, path loss will decrease. However, the Moon will be close to Sagittarius A on the 28th, leading to very high noise. This will be prevalent on the lower VHF bands.

And that’s all from the propagation team this week.

The news headlines:

• Ofcom consultation video guidance
• World Radiosport Team Championships
• RSGB coding activities

The RSGB has just released a video in which RSGB Spectrum and licensing expert Murray Niman, G6JYB, explains more about Ofcom’s Consultation on “Updating the amateur radio licensing framework”. This is the biggest revamp of amateur radio licensing and callsign policy in a generation. The video forms part of the RSGB’s wider guidance for radio amateurs on this Consultation. You can watch it on the RSGB’s YouTube channel or on the Society’s consultation web page at rsgb.org/licencereview

The UK has been awarded the hosting rights for the 10th World Radiosport Team Championships, which will take place in July 2026. Sometimes referred to as the ‘Olympic Games of amateur radio’, the WRTC is hosted by a different nation every four years. To find out more about this radio contest event, which will take place in East Anglia, see wrtc2026.org

As part of the RSGB’s commitment to encourage youngsters into amateur radio and to support lifelong learning, the Society is providing resources and creating coding activities for people to try throughout the month of September. From the BBC Micro:bit to Node-RED and GNU Radio, there will be detailed activity sheets available on the RSGB’s website. The RSGB hopes this will give you ideas to try yourself, with your club or to use as a workshop at your local school or community group. Some clubs are already planning workshops and there will be details of those on the website to inspire you too. Find out more at rsgb.org/coding

Each RSGB Board Director has a liaison role between the Board and specific aspects of the Society’s work. The General Manager also has operational responsibilities. The RSGB’s Board web page now has a list of the different responsibilities for the current Board. The Society hopes that RSGB Members will be able to use this as a guide to help them know who to contact if they have questions, concerns or ideas about any areas of the Society’s activities. You can contact each Board Director, and the General Manager, via the email address shown by their name. Go to rsgb.org/board to find out more.

A reminder now that every Thursday, a global net called ‘APRSThursday’ takes place using the Automatic Packet Reporting System, also known as APRS, for 24 hours. For amateurs who have APRS equipment, it is an opportunity to explore the mode and make contacts with other stations joining the net.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 13th of July 2023

Last week saw the arrival of one of the biggest sunspots of this cycle. Active region 3363 could swallow the Earth four times over. It is a source of M-class flares, but at the time of writing hasn’t produced any X-class events.

A new sunspot region 3372 has just rotated into view and has also been the source of eight M-class flares, one of which may have caused a coronal mass ejection that could give a glancing blow to the Earth this weekend – watch this one for more activity as it rotates into an Earth-facing position.

Meanwhile, the Solar Flux Index has been hovering around the 200 mark, meaning daytime MUFs over a 3,000km path are around 21MHz, sometimes slightly lower. At night this falls to around 14 to 18MHz so don’t write off HF once the sun sets.

Next week, NOAA’s Space Weather Prediction Centre has the Solar Flux Index around 175. While we have been lucky that Earth has not been subjected to too much geomagnetic disruption, after any disturbance across the weekend, the Space Weather Prediction Centre has forecast that the Kp index will be around two again all week.

So it may be ideal for DX, like Silvano 9Q1AA/9Q1ZZ in the Democratic Republic of the Congo, who has been active on the 10 and 15m bands recently. Or the KH8RRC DXpedition to American Samoa which is active until the 18th.

Remember, there is DX to be worked – you’ve just got to pick the right band and time.

And now the VHF and up propagation news

The predominant theme this week is driven by low pressure systems, meaning further days of heavy rain or thundery showers and a distinct lack of Tropo from areas of high pressure.

However, there is a split in the different models' view for southern Britain later in the coming week in which some try to build a ridge across southern UK and France from the Azores high. Check the forecast charts from Wednesday onwards to see which version ‘wins’.

In the meantime, the heavy rain will continue the recent good run of rainscatter on the GHz bands.

Sporadic-E will probably continue to be a feature on most days somewhere in Europe. Last Wednesday night saw another good opening to Newfoundland.

Remember that there are plenty of online clusters and map plots showing where the focus of activity is located. Each day a blog is published on propquest.co.uk detailing the locations of likely Sporadic-E activity, based upon the positions of various weather features suspected of being responsible for the location of Sporadic-E patches.

The recent behaviour of the Sun has regularly affected the prospects for VHF propagation by interaction with the Earth’s magnetic field giving a high Kp index, above five, which can be a sign of auroral conditions.

A high Kp index is potentially a bad thing for Sporadic-E prospects, some operators suggesting that it is possible that solar flare activity may also be a negative influence on Sporadic-E. Meteor scatter prospects continue to improve due to two broad-peaked showers coming up later in the month.

This weekend sees maximum Moon declination but losses are high as we approach apogee next Thursday. 144MHz sky noise is moderate until Monday when the Sun is close to the Moon for the whole day’s pass, lasting until 9am on Tuesday. After this, sky noise is low for the rest of the week.

And that’s all from the propagation team this week

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 6th of July 2023

NOAA’s prediction that the Solar Flux Index, or SFI, would decline last week didn’t come to fruition. In fact, the SFI stayed in the 160s and 170s until Thursday, when it declined to 155.

The Sun produced more than 160 sunspots in June, the highest monthly number in more than two decades. This has led some newspapers to run more doom and gloom stories about solar Armageddon, while we amateurs look forward to some F2-layer DX!

Unfortunately, more sunspots do mean more chance of solar flares and coronal mass ejections, but we have to take the rough with the smooth.

As an example, we had an X1-class solar flare on the 2nd of June. This occurred at 2314UTC so didn’t affect the UK, but did cause an R3 radio blackout over the west coast of the USA and Pacific.

Otherwise, there is still DX to be bagged for well-equipped stations, such as Eric, FP/KV1J on St Pierre and Miquelon islands on 12m FT8, and Marek, FH4VVK, on Mayotte island, on 10m FT8. Other DX worked this week by CDXC members includes the 4W6RU DXpedition on Timor Leste on various bands; Robert, 9N7AA in Nepal on 12m FT4; and V31XX in Belize on 20m CW.

Next week, the Space Weather Prediction Centre has the SFI at 155, rising to 175 by the end of the week. Unfortunately, the Kp index is forecast to rise to four over the weekend, possibly due to a large Earth-facing coronal hole, and again up to Kp five on the 12th and 13th. If it happens, expect noisy bands and a decline in the maximum usable frequency.

As always, we encourage you to get on the HF bands, in the evening, nighttime and especially around dawn, which is when a lot of HF DX is being worked.

And now the VHF and up propagation news

Low pressure dominates the whole weather pattern this coming week, driven by an active meandering jet stream across the Atlantic.

This provides several regions where the turbulence, generated on the edge of these strong winds up at 10km, can propagate upwards to trigger Sporadic-E propagation at about 110km height in the E region.

So, unsurprisingly, Sporadic-E will feature as a ‘go-to mode’ for the coming week. Typically, single-hop paths within Europe will produce very strong signals, whereas multi-hop paths, for example across the Atlantic, will require several such refraction points from Sporadic-E patches, plus intervening reflections from the sea surface, and will have much higher losses.

These will usually be weak signals and probably very fleeting in view of the complex geometry of such paths.

Tropo need not concern us this week, but rain scatter is worth a look since the unsettled weather will provide several heavy rainfall events in some areas. Look for the brighter echoes on the rainfall radar displays, especially those associated with thunderstorms.

Random meteors could be useful in the early morning hours. We also have the start of two showers, Alpha Capricornids and Delta Aquarids, during next week, which don’t actually reach a peak until the end of July. So prospects for meteor scatter and Sporadic-E propagation are improving this month.

The aurora chances may be reasonable initially in view of the recent coronal hole transition, so keep an eye on the Kp index.

Moon declination goes positive on Sunday so there will be lengthening Moon windows. Path losses are currently low but will rise all week. 144MHz sky noise is low to moderate all week.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 29th of June 2023

The solar flux index stayed in the 150s and 160s last week, which is good news for HF propagation. From a flare and CME perspective, we have been lucky in that we have only had a few solar flares, all of which have been C- or M-class.

As a result, the Kp index has remained fairly low, being in the range of one to three after the rise to a Kp of five on the 25th due to the solar wind’s magnetic field, or Bz, tipping south.

We are, however, still in the summer doldrums, so daytime DX is limited thanks to D-layer absorption. We still recommend checking the bands at night as the MUF over 3,000km is still exceeding 14MHz and often reaching 18MHz at times. During the day Sporadic-E may still keep you entertained on the higher HF bands.

Daytime critical frequencies are around 5.2 to 6.7MHz according to the Dourbes ionosonde, which means you may find close-in contacts tricky on the 40m band at times, whereas more DX distances are still fine. Near vertical incidence skywave or NVIS, 40m signals may not be returned to Earth with that critical frequency.

Looking ahead, active sunspot region 3354 was pointing directly at the Earth on Thursday but has so far been behaving itself with mostly C-class flare events. It is still the most likely candidate for a coronal mass ejection, or CME, over the weekend.

Next week the Space Weather Prediction Centre has the Solar Flux Index declining to 130 before picking up later in the week to perhaps 145. The Kp index should remain around two unless we have a CME which could see it rising to five with the attendant lowering of the MUF.

Meanwhile, you can get an idea of the best times to work various parts of the world by using the free Proppy software at soundbytes.asia/proppy or via VOACAP.com

And now the VHF and up propagation news

The next week or so looks likely to continue in a very unsettled theme with low pressure residing over Scandinavia for much of the time and producing a west or north-westerly pattern over the UK.

This will mean that tropo propagation will not be a large part of our operations during the period ahead. On the other hand, the frequent spells of fronts with prolonged rain or heavy summer showers will make rain-scatter modes a good use of time on the GHz bands.

Talking of scatter modes, we are not in a major meteor shower at present, so random meteors are a good fail-safe although it can entail spending a lot of time in the process.

The solar conditions, as previously mentioned, can be unsettled at the moment, and thus there is a potential for radio aurora if the Kp index goes above seven or so, even though daylight makes visible events unlikely at this time of the year.

Lastly, the Sporadic-E situation is still our primary focus as we move into July. Days with good jet stream activity over Europe are good signs, whereas a high Kp index or solar flares are generally not so good.

Of course, there are many other parameters involved and one of the critical components is likely to be the random meteor count which shows how much meteor debris might be available to make the Sporadic-E patches. In a roundabout way, if you monitor the meteor pings you might get a feel for how the Sporadic-E prospects are stacking up.

The Moon declination is negative all week so there will be short Moon windows. Tuesday’s perigee means that path losses are at their lowest for the month. 144MHz sky noise is high this weekend but falling back to low levels by the end of the week.

And that’s all from the propagation team this week.

The news headlines:

• Ofcom consultation on updating the amateur radio licensing framework
• RSGB Tonight@8 webinar
• ‘Fly Your Satellite!’ programme

An Ofcom consultation titled “Updating the amateur radio licensing framework” opened on Friday the 23rd of June 2023. According to Ofcom, the proposals set out in the consultation aim to “provide greater operating freedom for radio amateurs; and make the process of getting and using a licence simpler, clearer and more responsive.” The closing date for responses is the 4th of September 2023. All radio amateurs are strongly encouraged to read the consultation via Ofcom’s website directly. You can also find the consultation by visiting rsgb.org/licencereview and clicking the Ofcom logo. The RSGB will provide guidance on how to respond to the consultation via the same web page in due course.

The next RSGB live Tonight@8 webinar will take place at 8pm on Monday the 3rd of July, with Eric P. Nichols, KL7AJ presenting “Receiving antennas are different”. Eric, who has written numerous amateur radio and electronics articles over the past 30 years, says that almost every ham radio station can benefit from a separate receiving antenna. Effective receiving antennas are optimised for best signal-to-noise ratio, not necessarily the greatest gain. Tune in to the RSGB YouTube channel or special BATC channel to hear Eric discuss the countless interesting means of building high signal-to-noise ratio receiving antennas. You can find out more at rsgb.org/webinars

The ‘Fly Your Satellite!’ programme, initiated by the European Space Agency, presents an exciting challenge for radio amateurs and space enthusiasts worldwide to establish communication via the LEDSAT CubeSat digipeater. This unique opportunity invites participants to connect with the ESA Education Office ESTEC Ground Station in the Netherlands through the satellite digipeater, with a chance to win a special prize – a custom QSL card issued by the ESA Education Office and the LEDSAT team. Running from the 26th of June to the 30th of July, this challenge offers an exciting chance for radio enthusiasts to engage with space technology and demonstrate their communication skills. For more information go to the European Space Agency website at esa.int and search for “Connect and communicate with a satellite via the LEDSAT Digipeater Challenge.”

It was with profound shock and sadness that the RSGB learnt of the untimely loss, at the age of 49, of Mr Alexandre ‘Sasha’ Kholod, Chairman of the CEPT WRC-23 Conference Preparatory Group. Alex was head of international frequency planning for the Swiss regulator and was widely respected and influential in CEPT and ITU. Of note to amateurs is that he chaired CEPT Project Team C which led to the successful ITU Region 1 50MHz allocation for the amateur service at World Radio Conference 19 in November 2019. His warm and professional personality will be sadly missed.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 22nd of June 2023

We had yet another week of high solar flux, plenty of sunspots, but also a major solar flare.

The Solar Flux Index reached 180 on the 20th of June with a massive spread of sunspots across both solar hemispheres. But an X-class solar flare erupted on the same day. This was only just X-class though, as at X1.1 it barely hit the requirements. Luckily, its associated coronal mass ejection was directed away from Earth.

We passed the summer solstice this week so are now heading towards Autumn. Don’t worry too much, though, as there is plenty of summer left, complete with its lower daytime maximum usable frequencies and high levels of D-layer absorption. Fortunately, multi-hop Sporadic-E is also bringing occasional DX on the higher bands.

As we pointed out last week, nighttime MUFs remain high, partly due to seasonal norms and partly due to the high solar flux.

There were reports this week of 15m CW still being open at 3.30 am local time, when Paul, MM0ZBH worked the VP6A DXpedition on Ducie Island. There have also been many reports of VP6A being worked on the 80m band at around 0800 UTC.

Next week the Space Weather Prediction Centre puts the Solar Flux Index at around 165 to 180 again. We can expect unsettled geomagnetic conditions once again around the 27th and 28th of this month.

Daytime F-layer MUFs over a 3,000km path are generally around 21MHz, but there are occasional surprises. Sporadic-E still dominates on the 10m band. At night, MUFs over 3,000km are often around 14 to 18MHz, again with some surprises at times.

And now the VHF and up propagation news

After a slow change to a more summer-like pattern of showers and sunshine with occasional fronts in the last week, it does seem like it's a continuation for the coming week.

This means further opportunity for rain scatter on the GHz bands and with a reasonable chance of tracking the storms with any of the online weather radars.

There will be a tendency for higher pressure close to southern Britain with possible Tropo, which will extend south across Biscay to northern Spain or farther south towards the Canaries and perhaps beyond. It may even offer paths east across the southern North Sea towards Denmark.

There have been some reasonable Sporadic-E paths within Europe and beyond to the Americas. Paths have also opened eastwards to the Far East or Middle East and there is no reason not to expect similar for the coming week.

As next week progresses, the jet stream distribution may favour paths to Scandinavia and the Baltic, plus across the Atlantic to the States.

The recent unsettled solar conditions may affect the prospects for Sporadic-E propagation if the Kp index becomes too high, but on the plus side it could then be worth checking for aurora. Don’t forget that random meteors can provide a few chance QSOs using meteor scatter propagation and there have been audible meteor ‘pings’ on some Sporadic-E QSOs recently, so they do exist!

Moon declination goes negative again on Monday – so shortening Moon windows. Path losses will fall all week, and 144MHz sky noise is low to moderate until next weekend when it reaches more than 2500 Kelvin on Sunday.

And that’s all from the propagation team this week.

The news headlines:

• His late Majesty, King Hussein of Jordan’s UK amateur radio equipment
• Coding and amateur radio
• RSGB Convention 2022 presentations

The Radio Society of Great Britain is delighted to announce that Her Majesty Queen Noor of Jordan has chosen to donate the UK amateur radio equipment of His late Majesty, King Hussein of Jordan to the Society. His Majesty was a great ambassador for amateur radio and, whenever his official duties allowed him, his radio callsign JY1 could be heard on the amateur bands. His Majesty always operated modestly, never announcing himself as King Hussein, always just ‘Hussein from Jordan’. A permanent display is being organised at the RSGB National Radio Centre so that the equipment can be used to help inspire people to get involved in amateur radio and promote communication, friendship and understanding throughout the many countries and cultures of the world. The RSGB extends its thanks to Her Majesty for this generous donation.

National Coding Week has been run for many years in the third week of September. Coding is used increasingly in amateur radio, and the BBC Micro:bit and the Arduino have made it easier for radio amateurs of all ages to discover more about this. As part of its commitment to encourage youngsters into amateur radio and to support lifelong learning, the RSGB will be providing resources and creating coding activities for people to get involved in throughout the month of September. The Society is keen to hear from volunteers who have ideas for this initiative and would like to be part of it. Further details will follow but, if you’re interested, in the first instance please contact Exam and Syllabus Review Group member John Hislop, G7OHO via g7oho@rsgb.org.uk

The RSGB has released two further Convention 2022 presentations. In the first, Noel Matthews, G8GTZ provides an introduction to the challenges of operating on 122GHz and gives an overview of the VK3CV-designed transverter boards which have put operation within the reach of amateurs without requiring advanced electronic and mechanical engineering skills. He tells the story of how he and Dave, G1EHF used the boards to work up from their first QSO over 2km to breaking the UK record for 122GHz at 36.5kms. Secondly, in a presentation called “HF propagation – what do the numbers mean?” RSGB Propagation Studies Committee Chair Steve Nichols, G0KYA unravels what terms such as Solar flux index, SSN, A and K index, and Solar Wind Speed mean and explains how to find the best HF conditions. You can watch both on the RSGB YouTube channel at youtube.com/theRSGB

After serving for nine years, the RSGB Trophy Manager is retiring and the Society is looking for a new volunteer for this role. The position is part of the RSGB Volunteer Leadership Team, reporting to the Board. Working in close relationship with the three Contest Committees and the RSGB General Manager, the Trophy Manager looks after the RSGB’s trophies arranges for their engraving and presentation to recipients and maintains the trophies’ history. If you are interested in applying for the role or would like to find out more, please email gm.dept@rsgb.org.uk

The G-QRP Club is running a fun event called the Summer Sizzler from Saturday the 17th to Sunday the 25th of June. This is not a contest, rather it is a relaxed on-air QRP event. It is an ideal opportunity to meet and greet new and old friends, to test your latest homebrew creations and to fill the bands with friendly QRP activity. The best logbook for the event will win the inaugural GM3OXX trophy. This will be decided upon by adjudicators and will not necessarily be awarded to the entrant with the most contacts. Unusual or remarkable logbooks have just as much chance of winning. For more information visit gqrp.com/awards.htm

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 15th of June 2023

We had another week of sound HF propagation, helped by relatively quiet geomagnetic conditions, a lack of bad solar flares, and some good multi-hop Sporadic-E openings.

The Kp index never rose above three and was mostly ones and twos. This was no doubt helped by no M-class or higher solar flares and no Earth-directed coronal mass ejections. A large filament did break away from the Sun on the 12th of June, but luckily it was directed away from Earth.

The solar flux index declined to the mid-140s after reaching 172 on the 6th of June.

Paul, GM4ULS sent in an impressive log of 10m SSB contacts with Brazil, Argentina, Chile and Uruguay. These were mostly during the late afternoon although Paul says the openings often started around noon. F2-layer propagation was the first thought, but closer analysis suggests that these were more likely to be multi-hop Sporadic-E.

If these contacts die out as we progress through the summer that should confirm that they were multi-hop Sporadic-E. Paul does have one tip. He listens to 27.555MHz, which is the SSB CB calling frequency. If he hears activity there he then fires up on the 10m band.

Other DX this week has included VP6A on Ducie Island in the South Pacific. This DXpedition should be active until the 26th of June, so there is still plenty of time to work them. 8Q7KB in the Maldives should also be on until the 21st of June.

Next week, the Space Weather Prediction Centre thinks the Solar Flux Index will start the week at around 150, rising to 170 as the week progresses. After a geomagnetic disturbance this weekend that may see the Kp index rise to four, and is likely caused by a coronal hole on the Sun’s surface, we may expect quieter conditions next week with a maximum Kp index of two.

And now the VHF and up propagation news

There has been some excellent Sporadic-E and super Tropo propagation during recent UK Activity Contest events. This is high-season for Sporadic-E, so it's worth a few notes to sharpen your DX potential.

There are often two main 'windows' of activity: mid-morning and late afternoon or early evening.

For early risers, there can be a surprise ‘window’ of activity around 0600 to 0700UTC on some days and this is particularly useful for paths across the pole to Japan and the Pacific.

The tendency is for openings to migrate westwards. Paths across Eastern Europe will be replaced by new paths to Italy or even Iberia as the particular event ‘window’ migrates west.

In this peak season the Sporadic-E operating ‘windows’ may almost merge into one continuous activity period, especially on the lower bands such as 10m and 6m. As paths to Portugal fade, the new cycle may be starting with paths to Scandinavia and the Baltic.

Multi-hop paths will be weaker than single-hop, and often more fleeting due to the complex geometry required, making the slower data modes frustrating. Add this to frequency spreading, and sometimes slick, fast CW can be the best mode if you can find the activity.

The prolonged high pressure has provided some very good Tropo paths, particularly across the North Sea to Scandinavia. This may not be so reliable in the coming week as low-pressure moves in and offers heavy thundery showers as a source of rain scatter for GHz operators.

Meteor scatter and aurora are always possible, but Sporadic-E will probably be too much of a distraction.

Sunday sees peak Moon declination but with apogee this coming Thursday, path losses will be at their highest.

144MHz sky noise is moderate until Saturday afternoon when the Sun and Moon are very close in the sky, spoiling the weekend for VHF EME. This “close to eclipse” condition persists until Sunday night after which noise levels are low to moderate for the rest of the week.

And that’s all from the propagation team this week.

The news headlines:

• RSGB President's IRTS speech
• Contest group map
• Distance learning for Full licence exam

RSGB President, John McCullagh, GI4BWM received a warm welcome when he attended the IRTS AGM Gala Dinner recently. He talked about the challenges faced by national societies, as well as the success of the RSGB’s Tonight@8 live webinars and online exams, which were introduced during the pandemic. John also stressed the importance of engaging young people in amateur radio, through the Society’s work with schools and universities. He is featured on page 10 of the June issue of Ham Radio Ireland Magazine.

As part of the RSGB’s new Club Finder facilities, the Society has launched an online map that shows affiliated contest-only clubs and groups. If you’d like to get involved in a group, you can use the map to search locally and more widely. Depending on the club entry you will be able to see which contests they participate in as well as their contact and website information. If you are part of an RSGB-affiliated contest group or club, please check your details and, if they need updating, log into the RSGB members’ portal. New information will be uploaded to the map every Friday afternoon. You can find the map on the RSGB’s contest web page at rsgb.org/radiosport

Since 2011, the Bath Based Distance Learning team has helped nearly one thousand students to obtain their Full licence. Student feedback is always very positive and the pass rate continues to be well over 80%, compared with a national average of around 66%. The BBDL team is now planning another Full-licence level course. The course will run from the end of August to December, with exams in January. Students receive weekly work packages via an online classroom and have access to weekly online tutorials. Each student is allocated to one of the remote tutors who provide feedback and additional guidance. There are weekly quizzes to check on progress and at the end of the course there are a number of mock exams. There is no charge for the training, but applicants must work through some pre-course material and complete a quiz to be eligible for a place. This focuses on the ‘new’ Intermediate topics that were introduced to the syllabus in 2019. The aims of the pre-course classroom are to make sure applicants can use the BBDL systems and to ensure that they are ready for the current Full training syllabus. Each student will need to provide their own RSGB Full licence textbook and arrange their own exam at the end of the course. Advice will be provided as part of the course. The deadline for course applications is Tuesday the 25th of July. To request full details and an application form, please email BBDL Team Leader, Steve, G0FUW, via g0fuw@bbdl.org.uk

International Museums on the Air will take place on the weekends of the 17th and 18th, and the 24th and 25th of June. A participation award will be issued to all stations that register.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 8th of June 2023

Solar activity has remained at low levels over the past few days with only minor C-class and one M-class flare detected. The majority of these small flares were produced by active region 3327 in the southeast quadrant.

But a large number of sunspots means we are at a high risk of M-class or even higher flares over the next week.

HF conditions for last weekend’s Field Day were good and most teams put in good scores. Sporadic-E wasn’t too evident on HF, but there was plenty of F-layer DX to be had and luckily an anticipated geomagnetic storm never materialised.

The Kp index remained low for the whole weekend, apart from a brief excursion to Kp4 late on Sunday evening, which only lasted until the next three-hourly update.

Next week the Space Weather Prediction Centre thinks the solar flux index will be in the range of 140 to 155, with 155 coming much later in the week. We may expect some geomagnetic disturbance over this weekend, with the Kp index perhaps reaching four on Sunday the 12th.

Looking further ahead, the 18th to the 21st is predicted to be unsettled with a maximum Kp index of five.

We really are into a period of summer HF propagation now, which is characterised by lower maximum useable frequencies during daylight hours, but higher MUFs during night-time.

According to Propquest, night-time MUFs over a 3,000km path are staying well above 14MHz and even 18MHz all night. You may even find DX on 21MHz up until midnight. So don’t write off the HF bands after dark as you may get some surprises.

And now the VHF and up propagation news

Sporadic-E produced some remarkable conditions early last week with 50MHz FT8 QSOs made with Australia during the day and afternoon and evening openings to the Caribbean, Central, North and South America on FT8 and CW.

Caribbean signals were still being copied at 2200UTC on some days.

The 5th produced QSOs for many on 70MHz including S01WS in Western Sahara. We are still in the peak Sporadic-E season, so it is well worth keeping a check on band activity via the various clusters or simply listening, particularly in the late afternoon.

The current weather setup is quite typical for this time of year and can be remarkably persistent. Although there have been suggestions of unsettled thundery weather arriving, it may be a brief visit and rather limited in extent. Some eastern areas stay close to the high pressure which becomes more dominant again throughout next week.

This means that Tropo will still be a component of the coming week’s propagation, especially along North Sea coasts, although this will tend to favour northern Britain as the week progresses.

The thundery weather could introduce rain scatter, especially to southern and western areas, and these storms should be easy to track in view of the light upper winds.

Recent solar conditions, as detailed in the previous section, continue to provide propagation variety with chances of aurora plus the usual mention of random meteor scatter.

Moon declination is still negative until Monday, and, as we are past perigee, we will have lengthening Moon windows and rising path losses. 144MHz sky noise is low all week.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 1st of June 2023

We had a relatively calm period last week with the Kp index remaining below three and plenty of sunspots. Although we started the week with the Solar Flux Index in the low 150s, it quickly picked up to reach 161 by Thursday.

As a result, there was DX to be had, although most of the attention was on 6m where some outstanding multi-hop DX contacts were being made.

But back on HF and people have been chasing T31TT on the Central Kiribati Islands. Some have made it, but it's a difficult path.

Closer to home, Nobby Styles, G0VJG and Emil, DL8JJ have been active on Rockall, which is IOTA EU-189, using the callsign MM0UKI.

Rockall is an uninhabitable granite islet situated in the North Atlantic. The nearest permanently inhabited place is North Uist, an island in the Outer Hebrides of Scotland, 200 nautical miles to the east.

They have been worked from the UK mainland on 30m and 20m and heard in the east of England on 15m, possibly via Sporadic-E. They may have been a little too close to northern areas for 20m as you may have been inside their skip zone.

One of their aims is to raise as much as possible for the Royal Navy and Royal Marines Charity and ABF, The Soldiers’ Charity, so please support them if you can.

This weekend we may have unsettled geomagnetic conditions partly due to an Earth-facing coronal hole with the Kp index peaking at five.

But after the weekend things may settle with a maximum Kp index of two. The solar flux index is predicted to be around 150, declining to 130 as the week goes on, so HF conditions may be down a little on last week.

And now the VHF and up propagation news

The weather pattern seems stuck in its typical late spring/early summer state with cold north-easterly winds in eastern areas. There are good prospects for western Britain to shine but leaving eastern areas struggling.

The root cause is a large area of high pressure that is over northern Britain, and currently trying to transfer to the east, which could improve things. Either way, it does mean that Tropo was doing a lot of the propagation work last week and will do so for much of next week too.

As the high edges east, or splits into one to the west and one to the east of the UK, it could leave room for isolated thundery showers to encroach into southern and southwestern areas and give a chance of rain scatter on the GHz bands.

The main mode of interest will probably be Sporadic-E and there have been a few examples in the last week, both single-hop within Europe and multi-hop paths to the States, the Far East and Australia.

The first week of June is typically a prime period for Sporadic-E and although the jet stream position suggests mainly paths northeast to Scandinavia and Baltic regions will be best, other multi-hop options farther afield are worth exploring too.

Monitor the clusters and band maps to see where the activity is happening. If you hear this in time, you might want to check out the 24-hour UK Six Metre Group Summer Sporadic-E contest which ends at 1300UTC today, the 4th. There should be plenty of activity.

Other modes may also pop into view, such as aurora and meteor scatter, so we may be spoilt for choice.

Moon declination is negative all week and still falling until Tuesday. We are past apogee so path losses will fall as the week goes on. So we will also have short Moon windows with falling path losses until perigee late Tuesday. 144MHz sky noise is high, reaching a peak of 2700K on Monday and only going below 300K by Friday.

And that’s all from the propagation team this week.

Three weekends have been identified for some RSGB Beaconnect loop experiments. On the 3rd and 4th of June, there will be some regional loops and nets. On the 10th and 11th of June, there will be an England-only loop and net based round the activators who have registered for Beaconnect callsigns so far, but the Society would welcome new activators in the West of England and East Anglia. Finally, on the 24th and 25th of June there will be an attempt at a multiple nations loop, although to do so the Society will need activators in Wales, Scotland and Northern Ireland. If you want to join in with these activities, register for a Beaconnect callsign via the RSGB website. Go to rsgb.org/coronation and choose the Beaconnect information page.

The RSGB’s School Zone web page brings together radio amateurs in schools and colleges. The Society wants to help people to share their experience and expertise in establishing and running a radio club for young people. The RSGB has just launched a new page as part of this section called ‘School Zone stories’ where it is highlighting some of the great amateur radio activities that are happening in these, and other, schools. If you’re a school with an amateur radio club and want to be added to the list, or a radio amateur or club that is linking with local schools, the RSGB would love to add your information and stories to School Zone. Go to rsgb.org/school-zone to find out more, or send your stories and photos to comms@rsgb.org.uk

Have you seen the RSGB Live News web page? It brings together the Society’s social media feeds, latest YouTube videos and front-page news in one place. Launched a few years ago, people found it very useful, so the RSGB is highlighting it again now for those who have become radio amateurs or returned to amateur radio more recently.

The Solar Flux Index was consistently in the 150 to 160s range last week, with a total of eight M-class flares. We had unsettled geomagnetic conditions on the 21st and 22nd when the Kp index hit six, but things then settled down again to a more manageable two to three.

There are times when the F-layer critical frequency is lower than the E-layer critical frequency due to Sporadic-E. This means that HF signals can’t reach the F2-layer, basically blocking off DX, but leaving Sporadic-E short skip available. So, make the most of these short-skip contacts to the continent and multi-hop Sporadic-E skips to further afield. Conditions in the F2-layer will improve in the autumn, so don’t worry!

There is still HF DX to be had, but you may have to hunt for it. Recently, Laurie, G3UML worked BD4VGZ in China on the 15m band using CW and Stuart, M1SMH worked YG2ALQ in Indonesia as well as A71UN in Qatar, on the 10m band using FT8. Meanwhile, Andy, M0NKR worked VK on the 15m band using SSB long path. Namibia, Malawi and Equatorial Guinea have all been workable from the UK using FT8 on the 10m band during late morning.

Next week NOAA predicts that the Solar Flux Index will remain in the same range. That is, in the 150 to 160s. Unsettled geomagnetic conditions are forecast from the 2nd to the 4th of June when the Kp index might reach four. Otherwise, it suggests that conditions will be mainly settled with the Kp index around two to three.

So, make the most of the elusive HF F2-layer openings and the various opportunities available during this peak time for Sporadic-E propagation.

And now the VHF and up propagation news

The broad scale pattern is still dominated by a large area of high pressure over the country with its centre mostly to the northwest of the British Isles.

The whole period through to the end of the coming week should offer some good tropo prospects, so why not try using CW or SSB to add some extra squares to your log? Under lift conditions, even a halo antenna can be surprisingly effective.

The weather variety will remain until the end of next week when low pressure over France tries to push some thundery showers northwards into southern Britain after midweek, and perhaps then northwards as far as western Scotland. This brings a chance of rain scatter on the GHz bands.

There is, as usual, always a chance of aurora and meteor scatter to bring additional options, but the main mode of interest this week will be Sporadic-E as we head into the peak of the season.

With tropo also in play, it’s worth a quick note for those not used to working Sporadic-E; Tropo tends to be long-lasting and usually better on the higher bands. That is to say, the 70cm band is often better than the 2m band whereas Sporadic-E is usually brief and better at lower frequency bands. So, the 10m band is better than the 6m band.

This time of the year it can reach up to 2m on rare occasions. If you do nothing else, simply check the bands and clusters at the end of the afternoon to maximise your Sporadic-E chances.

Moon declination is positive but falling this weekend, going negative on Tuesday. We are past apogee so path losses will fall as the week goes on. We’ll see shortening Moon windows with falling path losses. 144MHz sky noise is low all week.

And that’s all from the propagation team this week.

The news headlines:

• Youngsters on the Air camp
• RSGB Board appointment
• RadCom Basics Editor

The RSGB has announced the team of young members who will be representing the Society and the UK at this summer’s Youngsters on the Air camp. The event, hosted by the Hungarian Radio Amateur Society MRASZ, will take place in Gyor, Hungary between the 5th and the 12th of August. The team is made up of team leader Alexander, 2E0FMZ and members Henry-James, M7HJR; Hannah, M7YYQ and Jake, M7JNS. You can read more about the camp and the team on the RSGB website at rsgb.org/yota-hungary

The RSGB Board has decided to co-opt Ian Shepherd, G4EVK as a Board Director until the 2024 AGM. Please see the Board’s explanation of this appointment on the Society’s website at thersgb.org/go/boardcoopt

The RSGB is sad to report that RadCom Basics Editor Lee Aldridge, G4EJB wishes to retire later this year. The RSGB thanks Lee for all his hard work and effort in the making of RadCom Basics. If you are interested in taking on the role of RadCom Basics Editor, please email radcom@rsgb.org.uk

Last year, the RSGB was approached by the BBC to find experts to contribute to its planned series ‘The Secret Genius of Modern Life’. For episode one, which takes a look at the bank card, Neil Smith, G4DBN re-created the Great Seal Bug – a wooden seal, gifted to the US embassy in Moscow in 1945, and which contained a covert listening device. The technology developed for the bug was an early example of RFID, which is what allows contactless card payments to work. Neil has now released a series of fascinating videos on his YouTube channel which explain the history of the Bug as well as the mechanical design and machining needed to re-create it. You can find the videos in Neil’s playlist on ‘Machining and Microwaves’ and you can watch the original BBC Two programme on BBC Sounds – this episode is available for a further seven months.

The RSGB National Radio Centre welcomes thousands of people through its doors each month and needs to expand its team of volunteers. If you are interested in becoming an NRC volunteer, you should enjoy meeting people and be prepared to work a minimum of one – preferably two – days per month. The team is particularly interested in recruiting new volunteers who are able to work at the weekend. The National Radio Centre has a fabulous set-up and full training on using the GB3RS radio station will be given. You will be joining a friendly and dedicated team. NRC volunteers also enjoy numerous benefits associated with volunteering at Bletchley Park. For more information about volunteering, please email NRC Coordinator Martyn Baker, G0GMB via nrc.support@rsgb.org.uk

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 18th of May 2023

After last week’s NOAA prediction that we would have settled geomagnetic conditions all week, it seems they were right! The Kp index never got above three – a miracle given the recent disruption due to coronal mass ejections and coronal holes.

The proton flux from the Sun has declined as well. However, an M9 solar flare on Tuesday from active region 3310, and numerous C-class flares, maybe a precursor to more flare activity next week.

With a solar flux index in the 130s and 140s, HF conditions have been quite good. Daytime maximum usable frequencies over a 3,000km path have usually exceeded 21MHz, with 24MHz seeing occasional F2-layer openings, as well as sporadic E propagation.

At the moment, the 10m band is mainly open to Sporadic-E propagation with more DX paths now locked out until the Autumn. This is in line with predictions, as the ionosphere changes in the Northern Hemisphere summer with a change to more diatomic elements, which are harder to ionise.

So, will our luck hold out next week?

The Space Weather Prediction Centre forecasts that the Solar Flux Index, or SFI, will decline slightly to the 120s and this weekend should be geomagnetically settled. However, it is predicting that the Kp index will rise again from the 23rd of May. It suggests that the Kp index may hit four or even five for a few days before becoming more settled again from the 30th.

The US Air Force disagrees and thinks the SFI will be higher, perhaps hitting 145 and even 155 by the 28th. It agrees that we are in for more unsettled geomagnetic conditions from the 24th to the 28th, possibly due to a coronal hole rotating into an Earth-facing position.

So, expect MUFs to decline if the Kp index goes up, with poor overall HF conditions.

It is certainly looking like this weekend may see the best conditions for HF, so we suggest you get your DXing in right now, with 14 to 21MHz offering the best prospects.

And now the VHF and up propagation news

The upcoming weather week will be predominantly high-pressure driven, with an elongated region of high pressure from the Azores to Scandinavia.

However, there is still scope for a few blemishes and as we end the current week it comes as isolated showers, especially in the south and weakening fronts over north-western Britain. Early next week, a brief period with low pressure over the near continent will threaten some heavier rain for south-eastern areas.

Concentrating on the high-pressure part of the story, this means Tropo is a strong player and will hopefully be in attendance for the 144MHz May Contest and 144MHz Backpackers Contest this weekend.

Remember that, in the summer months, Tropo becomes much weaker over the land during the stronger heating of the daytime sunshine but can become quite widespread overnight and around coasts.

The rainfall component can lead to good rain scatter options, especially as the summer usually produces more intense rainfall, so performs better as a scatterer on the GHz bands.

The other primary propagation mode is going to be Sporadic-E as we move into the peak summer months. Follow the position of jet streams on the upper air charts, shown on propquest.co.uk and described in a daily blog.

Don’t forget there are always modes like aurora and meteor scatter, which can add to the excitement, but will need to be checked each day.

Moon declination is at its highest this weekend for the Dubus EME 10GHz and up SSB/CW contest, peaking on Monday. With apogee next Friday, path losses will continue to increase.

144MHz sky noise is moderate early next week becoming low by Thursday.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 11th of May 2023

Our topsy-turvy world of HF propagation continued last week with geomagnetic storms, solar flares, coronal mass ejections, proton events and more.

The good news is that the solar flux index was at 170 by Thursday, but the bad news was that we had two episodes where the Kp index hit five and there were at least five M-class flares.

At least one of these flares was responsible for a coronal mass ejection, or CME, which swept past the Earth on the 10th of May with a solar wind speed close to 700km/s. Although it was fierce, it was relatively short-lived and the Kp index was back to three on Thursday the 11th.

The CME caused the maximum usable frequency over 3,000km to decline to around 21MHz at times on Wednesday, but by Thursday morning it was back up to nearly 28MHz.

The high proton flux also caused problems on the 10th of May. The protons, mainly from CMEs, move down the Earth’s magnetic field lines into the polar regions and cause massive ionisation of the polar D region leading to increased, or total, absorption of HF waves.

This effect may last for as long as ten days and is called a Polar Cap Absorption event, or PCA. This affects signals going over the poles, such as the UK to the west coast of Canada and the USA, or to Japan and the far east.

Meanwhile, we are now underway with the Sporadic-E season, so make the most of the short skip and potential multi-hop Sporadic-E DX on 14 to 28MHz.

Next week, the Space Weather Prediction Centre has the Solar Flux Index declining slightly into the 150s. This is still more than enough to maintain DX on 21MHz and higher at times. It also predicts that the Kp index will be no higher than a stable 2 all week.

However, that is hard to believe, with the level of solar activity at the moment, and we could reasonably expect the Earth to be hit with a CME or two at some stage. This could see the Kp index rising with the potential of reduced MUFs at times.

And now the VHF and up propagation news

After a very unsettled end to the week, with lots of rain scatter reported, it will soon quieten down as a ridge of high pressure builds across the country to give some limited Tropo opportunities for the start of the weekend.

This will not last long and by this evening, it will be heading back to unsettled with low pressure, heavy rain and rain scatter. This unsettled theme will last through the first half of the new week together with strong north-easterly winds. Thereafter, high pressure will build again for the second half of the week, providing further Tropo options.

Keep a watch for Aurora, especially in view of the current unsettled solar state. CMEs will mean a very unsteady Kp index and anything higher than five should get your attention for auroral propagation. No significant meteor showers are expected this week, but QSOs using random meteors are always a possibility in the dawn hours.

Likely to be of interest in the summer months ahead, there have already been Sporadic-E openings on 6m CW and FT8 into Europe. Early evening trans-equatorial 6m FT8 QSOs to South America, the Indian Ocean and the South Atlantic were reported from the UK last week.

Check Propquest.co.uk for daily blogs and make use of the DX cluster and map plots to see where the actual centres of activity are located.

Timings can be a bit random early in the season, but there tend to be two ‘openings’ per day – one in the morning and a second during the late afternoon or early evening.

Moon declination is rising, going positive again next Tuesday. But last Thursday’s perigee means path losses are on the increase. 144MHz sky noise is low until Friday when the Sun and Moon are close in the sky for the whole Moon window. Things return to normal early on Saturday and sky noise is moderate.

And that’s all from the propagation team this week.

You will need to log in to obtain your certificate. Beacon and repeater insurance certificates are available for an admin fee of £12 from the RSGB shop. Please allow a couple of days after renewal for your certificate to be dispatched.

The RSGB’s May Tonight@8 webinar is not in its usual slot on the first Monday of the month. To accommodate the two Bank Holidays, the live webinar will be on Monday the 15th of May instead. Put the date in your diary for an interesting presentation by Jack Purdum, W8TEE and Al Peter, AC8GY on the T41-EP ALPS: A High Performance CW Decoder.

Matthew, M0MZB from Calder Bridge in Cumbria, has become a SOTA Mountain Goat in impressive style. He reached the 1,000 activation point threshold with an overnight activation of High Stile G/LD-012 in the English Lake District. Matthew set up overnight camp on the summit of the long ridge above the western shore of Lake Buttermere. He operated both on VHF and HF and made a summit-to-summit contact with Alex Hill, G7KSE who was on the Dent summit, G/LD-045. Since getting involved in Summits on the Air, Matthew's expeditions have left many radio amateurs in awe. He has conducted many multi-summit expeditions without motorised transport, traversing between summits entirely on foot or by bicycle. Upon reaching the coveted Mountain Goat status, Matthew commented: "SOTA has given me new ideas for my little expeditions and has put me in touch with lots of new friends. The challenge of Mountain Goat has included many facets, from learning CW to antenna building, from battery technology to fishing poles." For more information about Summits on the Air visit www.sota.org.uk

Pubs and Clubs on the Air is taking place on the 12th, 13th and 14th of May. If you or your radio club or society is interested in taking part and operating a station, please email g1puv@yahoo.co.uk or visit the g6tw.co.uk website.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 4th of May 2023

Next week will see the Sun presenting with four large sunspots groups that are rotating to be Earth-facing, so look out for trouble. Just as the UK weather takes a turn for the worse, we expect the space weather to be unpredictable too!

Active regions 3293, 3294, 3296 and 3297 look dark and are looming large on the Sun’s face. Region 3293 emitted an M7.2 class solar flare on the 3rd of May, which the Space Weather Prediction Centre reported was likely due to an intensification of the magnetic field within the spot group.

The flare caused some degradation of the ionosphere, but nothing too serious. However, the Space Weather Prediction Centre now predicts that further flares could follow, perhaps even a strong X-class flare, which could have more serious effects.

If an X-class flare occurs in daylight over the UK, we can expect the HF bands to be affected in what is known as a sudden ionospheric disturbance or Dellinger fadeout. This could see the lower HF bands shut down due to extreme ionisation in the D-layer, only for the band to return to normal over a period of minutes to an hour.

More worrying is the fact that the flare could spark a coronal mass ejection, or CME, which, if Earth-directed, could cause the Kp index to rise, MUFs to drop and bring auroral activity a few days after the CME. So, keep an eye on solarham.net for updates.

Meanwhile, the solar flux index, or SFI, remains in the 150s and this looks set to continue. The US Air Force predicts the SFI will start the week at 152, then dip slightly, before reaching 170 by the 12th of May.

It also predicts that geomagnetic conditions will be settled once we get past this weekend, which could see the Kp index rise to four. These unsettled conditions may be due to a coronal hole, which became Earth-facing on Thursday.

Propagation-wise, F2-layer maximum usable frequencies over a 3,000km path has struggled to exceed 21 to 24MHz during daylight hours as we head towards summer.

The season is characterised as having lower MUFs during the day, but these tend to be maintained into the hours of darkness. Meanwhile, Sporadic-E might spring some surprises for paths over 800 to 2,200km on 14 to 28MHz, with very strong signals and rapid fading.

And now the VHF and up propagation news

The weather pattern is taking a change to unsettled as we move through this first May weekend, with low pressure dominating the charts and throwing active weather fronts across the country.

This will produce some quite heavy rain at times and perhaps even some thundery activity. This bodes well for rain scatter on the GHz bands.

This pattern extends well into next week, eventually changing from a south-westerly to a north-westerly followed by a building ridge of high pressure to bring a temporary hint of Tropo to end the week.

This opens the more exotic modes to consider, such as meteor scatter and possible aurora, but these are very much outliers to the main interest at this time of year, which is Sporadic-E. The season has nominally started, and daily blogs are being added to the website Propquest.co.uk, which describe the more likely regions to find Sporadic-E opportunities.

This unsettled weather pattern brings a useful bonus in that it is often associated with jet stream activity. The whole period offers several jet streams across Europe, a positive for the start of the new Sporadic-E season since jet streams are often associated with the location of Sporadic-E activity.

Moon declination is low and falling, reaching minimum next Tuesday. EME Moon windows will be short. Perigee is Thursday, so when you do have a view of the Moon, path losses will be low. 144MHz sky noise is high, reaching over 3200K late on Monday.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 27th of April 2023

What a busy week we’ve just had! It started with a massive G4 geomagnetic storm that saw the Kp index rise to eight with aurora visible as far south as Cornwall and the Channel Islands. This was due to a coronal mass ejection from a filament eruption on the 21st of April.

The 6m band came to life during the early stage of the storm with distorted aurora signals throughout the SSB and CW sections. However, the HF bands suffered, with MUFs down on the morning of the 24th. The 25th wasn’t much better with MUFs over a 3,000km path barely reaching 18MHz all day.

By Thursday the 27th the Kp index was still at four.

However, there were surprises to be had. Phil, GU0SUP reported that at 1300UTC on Monday the 24th, he was amazed to work Yuris, VU7W on the Lakshadweep Islands on 10m FT8, with good signals both ways. He says the Kp index was at six and the regular FT8 frequencies on both the 10m and 12m bands were pretty much dead.

On Wednesday the 26th, Peter, G8BCG reported, on the CDXC reflector, that 15m FT8 was open all night via the long path to Australia, New Zealand and the Pacific.

It is always worth checking the HF bands during a major geomagnetic storm as there may be surprises to be had.

Next week the Space Weather Prediction Centre thinks that the Solar Flux Index will remain in the range of 135 to 140. The Kp index may remain around two to three. However, as last week showed, we are now really into uncharted territory, in terms of solar activity, with daily multiple solar flares and associated coronal mass ejections.

So, don’t be surprised if we have another major geomagnetic disturbance with an elevated Kp index.

And now the VHF and up propagation news

The weather pattern in late spring often settles into a period of south-easterly winds from a rapidly-warming Europe and the signs are there for just such a flow during the coming week.

The sequence starts with unsettled weather and possible rain scatter from heavy April showers into the first weekend but, thereafter, a weak ridge of high pressure will move in to bring a chance of Tropo for next week. Paths along the east coast should do well, especially if there are large areas of sea fog and misty low clouds over the North Sea.

At longer timescales, the period towards the following weekend will see eyes looking towards a low to the southwest of the British Isles that could push some thundery rain into southern areas by the end of the week and again bring a chance of rain scatter on the GHz bands.

The jet stream pattern remains complex with several potentially useful flows that might be instrumental in prompting some early-season Sporadic-E propagation.

Last week, the Portuguese CS5BALG beacon on 50.036MHz in IM67, and CS5BLA on 50.0760MHz, made a welcome return. Sporadic-E can be very fleeting early in the season, but keeping a regular check on the usual beacons should give you a chance of being there at the right time.

The daily Sporadic-E blogs start on the 1st of May on www.propquest.co.uk and should give some clues as to any early-season options.

Lastly, the Sun has kept everyone busy recently with visible and radio auroras, so check the Kp index for aurora potential. And we are in a period when increasing meteor input is starting to help provide better meteor scatter prospects, as well as fuel for Sporadic-E. The Eta Aquariids has a broad peak zenithal hourly rate of around 50 next weekend on the 6th of May.

Moon declination is high and falling, meaning shortening EME Moon windows and peak elevations. We passed apogee on Friday so path losses will fall throughout the week. 144MHz sky noise is low to moderate.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 20th of April 2023

We had a surge in sunspot activity over the last week, pushing the solar flux index up to a maximum of 178, although it subsequently declined to 147.

Solar flare activity was quite subdued after a frantic period from the 13th to the 15th that saw 40 C-class flares and two M-class flares erupt.

This activity was mostly centred around active region 3282 in the northwest quadrant.

Geomagnetic conditions were unsettled for a time around the 18th and 19th with the Kp index hitting a maximum of 4.3. This appears to have been due to enhanced activity from a coronal mass ejection and continuing coronal hole activity that saw the solar wind speed hit more than 600km/s and the Bz swing south.

The critical frequency was down below 7MHz on the morning of Wednesday the 19th, which impacted near-vertical incidence skywave signals around the UK.

This impacted maximum useable frequencies, which struggled to exceed 21MHz over a 3,000km path on Wednesday, although by Thursday they were back over 28MHz again. A critical frequency of more than 10MHz meant the 40m band was once again suitable for close-in contacts around the UK.

There were many reports of DX being worked later on during the week, with Australia and New Zealand topping the bill on 18MHz and 28MHz.

Next week NOAA has put a more positive spin on sunspot activity. The Solar Flux Index is predicted to be in the range of 168 to 172 for the first half of the week, falling to around 160 in the second half.

But we could be in for a bumpy ride geomagnetically, with the Kp index predicted to hit five on Wednesday the 26th of April through to Monday the 1st of May. This may be due to the return of solar phenomena that occurred 27 days ago and saw the Kp index get up to 4.67.

Meanwhile, a very large solar coronal hole, albeit positioned very south on the Sun’s surface, and a much smaller one on its equator, threaten HF conditions this weekend.

Keep an eye on the real-time solar wind from the ACE spacecraft for signs of a rise in speed and a southward-pointing Bz interplanetary magnetic field on solarham.net. This could push to Kp index higher, perhaps to four.

And now the VHF and up propagation news

The Sporadic-E season is nearly upon us. Remember it will usually activate on 28MHz and then higher bands will follow if the event intensifies. There have been some 50MHz FT8 paths flagged up on DXmaps.com, although some may have been tropo.

The recent large high pressure centred over Scandinavia has been a bit subdued as regards Tropo. Much of the time, the air nearer the surface has been fairly dry with little sign of banks of sea fog over the North Sea, which would suggest better ducting potential.

We are now entering a phase with low pressure on the charts, initially over the south of Britain, but edging north for a time before drifting out across the North Sea.

This could produce some rain scatter on the GHz bands, especially should any heavy April showers develop.

Early next week a ridge will edge south across the UK in a colder northerly weather pattern, so although high-pressure returns, it may not be especially good for tropo.

The third changeover comes after midweek when a milder south-westerly returns with active fronts bringing rain and unsettled weather, especially to the north and west. This could mean further opportunities for rain scatter on the GHz bands and perhaps a hint of tropo in the Southeast towards the continent.

Aurora and meteor scatter are well worth considering, and the Lyrids shower peaks on Sunday the 23rd. The message is to monitor meteor scatter frequencies and the clusters for signs of activity and, of course, try putting out a CQ call!

Moon declination is positive and rising, meaning increasing Moon time and increasing peak elevation until peak declination on Tuesday. Moon apogee is next Friday so path losses increase all week.

144MHz sky noise is moderate to low.

And that’s all from the propagation team this week.

The RSGB Regional Forum has created Facebook pages for each of the 13 regions. These pages focus on regional amateur radio communities and are moderated by members of the RSGB Regional Team. Whilst the pages share a similar style, they are very different in content. Selected posts are created by the RSGB moderators to maintain some news content from the RSGB, but the main content comes from clubs, individual licensees and also event organisers in those regions. The pages also provide a forum where anyone can ask for help with any part of the hobby. Clubs are positively encouraged to post news and events on the pages. You can find them on Facebook by searching for ‘RSGB Region’ and the number of your local region, for example, ‘RSGB Region 1’.

SOS Radio Week 2023 starts at midnight on the 1st of May and concludes at midnight on the 31st of May. It is an opportunity to support the many voluntary organisations in the British Isles whose members volunteer to save the lives of others at risk around the many miles of its coastline, and out at sea. These organisations include the Royal National Lifeboat Institution, the National Coastwatch Association and numerous independent lifeboat and coastal rescue groups. Individual amateur radio operators and clubs are invited to register to become an official SOS Radio Week station and operate under their own callsign, their club’s or a special event callsign to raise awareness of the great work these volunteers perform. Awards are available for registered stations that make the most contacts on each of the 160m to 70cm bands and using various modes. Registration is now open and further details can be found at sosradioweek.org.uk

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 13th of April 2023

A news item this week suggested that the peak of solar cycle 25 could be coming earlier than expected. According to a paper in Frontiers in Astronomy and Space Sciences, by solar scientist Dr Scott Macintosh, the solar maximum may now be coming between late 2023 and mid-2024. So, make the most of the higher Solar Flux Index now!

Solar activity picked up nicely over the past week. The solar flux index rose to 154 and there were eight active regions on the Sun’s visible face by Thursday the 13th. Nevertheless, daytime maximum usable frequencies, or MUFs, remain down a little, which has probably more to do with seasonal ionospheric changes than reduced sunspot activity.

As we head towards Summer we will see the daytime F2-layer MUF decline further before it picks up again in the Autumn.

We also saw some M- and C-class solar flare action this week, but this was not really enough to cause serious problems to the ionosphere.

Next week NOAA predicts the Solar Flux Index will continue to increase, perhaps peaking at 160 around the 16th to 18th of April. Unsettled geomagnetic conditions are forecast for the 18th, perhaps with the Kp index rising to four.

The forecast for International Marconi Day on the 22nd of April is for a Solar Flux Index of 155 and a declining Kp index of three, which bodes quite well for the event.

In all, the Solar Flux Index is expected to be in the range of 140 to 160 for the rest of the month.

And now the VHF and up propagation news

A big contrast is coming next week, so it’s time to dust off the VHF gear again!

The unsettled weather of this last week will make a complete swap over to more settled high-pressure systems next week.

Initially, on Sunday this will appear as a ridge over the North Sea from a large high over Scandinavia. This will then gradually extend across the country and will eventually be joined by a second high west of Britain.

The end result will be enhanced Tropo prospects in the coming week and potentially good conditions for the 23cm UK Activity Contest on Tuesday the 18th and the 4m UK Activity on Thursday the 20th.

Those who enjoy rain scatter propagation in this current showery weather will have to look for other modes by Sunday, once the high pressure builds.

As we are coming out of the Winter lull in meteor shower activity, with the medium-rate Lyrids peaking on the 23rd of April at 0100UTC with a Zenithal Hourly Rate, or ZHR, in the 20s, it's well worth a look for meteor scatter contacts.

The end of April normally prompts a return of isolated Sporadic-E reports on the 10m band and perhaps even with data modes on 6m. The upper troposphere jet stream charts suggest it’s got some potential, especially between Mediterranean countries although not quite so positive for paths nearer to home.

The solar conditions may continue to offer a random chance of some aurora, so remember to keep an eye on the Kp index if it goes above five.

For EME operators, the Moon perigee is on Sunday so path losses are at their lowest. Moon declination is rising, going positive on Tuesday meaning increasing Moon time and increasing peak elevation passes.

144MHz sky noise is low, but the Moon is close to the Sun on Wednesday and Thursday meaning high Sun noise for those days.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 6th of April 2023

Solar activity declined this past week with the Sun looking distinctly spotless, other than active region 3270.

In fact, this has even prompted some amateurs to question whether we are now past solar maximum for this cycle. Rest assured, we shouldn’t be, as it is pretty common for cycles to ebb and flow as they develop.

Having said that, half of the Sun’s face is currently spotless, and NOAA predicts that the solar flux index will be in the range of 110 to 130 next week.

Geomagnetically, things have been reasonably settled with the Kp index reaching a maximum of 4.67 over the past seven days. NOAA predicts that it could rise to four on the 10th and 11th of April but will otherwise stay pretty much as it is in the range of two to three. This may be due to a coronal hole that is currently making its way across the Sun’s face in a near-equatorial position.

However, we may not have seen the last of the activity from active region 3270, which has increased in both size and magnetic complexity during the past 48 hours and could soon produce a moderate M-Flare. But, if you are reading or hearing this on Sunday, the region will be moving out of sight and is therefore no longer a threat.

Daytime F2 critical frequencies at midday remain around 9 to 10MHz giving a maximum useable frequency, over a 3,000km path, of just over 28MHz.

If 10m isn’t doing it for you we suggest moving down to 12 or 15m. Night-time F-layer critical frequencies are around 3 to 5MHz meaning MUFs over 3,000km are below 14MHz, leaving 3.5, 7 and 10MHz as the best bets for nocturnal DX.

And now the VHF and up propagation news

The current spell of high-pressure weather with enhanced Tropo, which turned up in time for the 2m UK Activity Contest on the 4th of April, is looking a bit vulnerable as active weather fronts come in from the Atlantic.

We are likely to have a brief change to unsettled conditions weather-wise before the start of the Easter weekend and again see some rain scatter opportunities on the GHz bands.

Scandinavian highs are often long-lasting at this time of the year and this high will regain control by Good Friday and should dominate over the UK during the Easter weekend to give some useful tropo possibilities again.

However, quite early next week a new powerful Atlantic jet stream pushes into northern France and will bring a return of unsettled weather and perhaps more rain scatter.

The Sporadic-E season is approaching and the higher HF bands like 10m can show good examples of Es, even during the second half of April, so a good chance to get into the habit of checking your ‘go to’ list of 10m beacons as recently updated by Steve, G0KYA, on the propagation section of the RSGB website.

The other defaults of auroral propagation have had a good run recently and random meteor scatter could also prove fruitful as we are soon ending the early year ‘drought’ of meteor showers with the arrival of the Lyrids later this month.

For EME operators, Moon declination is negative and falling, reaching its minimum next Wednesday. Moon time will be limited to low-elevation passes, but with low path losses as we approach perigee on the 16th.

144MHz sky noise is increasing to a high of more than 2,000 Kelvin next Wednesday before falling back to the mid-200s the following Sunday.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 30th of March 2023

We were right in our prediction about the effects of the large solar coronal hole last week, which saw the Kp index peak at 7.67 with widespread aurora visible from the UK, even in the south.

This was probably the most significant geomagnetic event we have had so far in this solar cycle.

Last week saw another X1.2 solar flare erupt on the Sun. This one erupted from active region 3256 on the 29th of March at 0233UTC. It didn’t impact the ionosphere over the UK, but a fadeout was observed over the Pacific region.

This was the seventh major solar flare since 2023 began. The Sun has now matched 2022’s total –and it's only March!

The associated CME off the southwestern limb of the Sun was modelled and determined to be well ahead of the Earth’s orbit. This means that we are unlikely to see the Kp index rise as a result of this event.

This region also produced an M1.2 flare that peaked around 1407UTC and an M1.1 flare at 2347UTC. The earlier flare didn’t seem to affect the ionosphere too much according to the ionosonde data.

A minor solar wind stream is heading for Earth and is due on Saturday the 1st of April. The material is flowing from a relatively small coronal hole in the Sun's atmosphere, but it is on the equator and very Earth-centric. Expect Arctic auroras and an elevated Kp index when the solar wind arrives this weekend.

The SFI remained fairly static, around 160, earlier in the week but then declined to 148 on Thursday the 30th. NOAA predicts that this decline will continue next week, perhaps down to the low 130s. Once the weekend’s geomagnetic conditions recover, NOAA predicts that the rest of the week should be quite settled.

This is good news for HF propagation, although do continue to watch out for solar flares and CME activity which could affect conditions and MUFs.

And now the VHF and up propagation news

We have three phases of weather to consider over the next week. Forecasts predicted an unsettled weekend with rain and strong winds, so should have provided a focus for rain scatter on the GHz bands.

The weekend ends with developing high pressure which lasts into early next week. There is good potential for some tropo from Sunday afternoon until about Tuesday lunchtime.

At the time of writing, the best paths are likely to be from southern England into the near continent, also via Biscay to northern Spain and across the southern North Sea to Denmark.

The third phase occurs when the high moves to the south to allow fronts to move in from the Atlantic across northern Britain, but possibly still leaving tropo into France and across Biscay. Later in the week, the high pressure may head back north again to reintroduce tropo to northern areas.

The Sporadic-E season is fast approaching, typically from mid-April on 10m. If anything does happen before then, check the propquest.co.uk website for the Es blog tab, which shows the current day’s jet streams and will maybe provide a clue for which direction to beam.

Remember to look for aurora if the Kp index reaches five or more and, of course, meteor scatter around dawn for those random meteor QSOs.

For EME operators, Moon declination is positive until Wednesday, so still plenty of Moon time to get some QSOs in. Perigee was last Thursday, so path losses are now falling. 144MHz sky noise is low, rising slowly throughout the week.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday 23rd of March 2023

The solar flux index dipped a little last week, down to 148, but it didn’t last long and was back up to 159 by Thursday the 23rd. We were free of major solar flares with only one M-class flare occurring on the 20th.

Geomagnetic conditions were mainly settled as well, but that could change this weekend thanks to a large coronal hole.

The massive coronal hole on the Sun became Earth-facing on Thursday. A coronal hole is an area on the Sun’s surface with open magnetic field lines, which allows plasma to flow out. They appear dark when photographed in extreme UV light.

Although the bulk of the hole is south of the Sun’s equator, a long finger reaches out to the equator, which makes it a potential threat to Earth.

All eyes will be on the Kp index over the weekend as we expect it to increase, possibly dramatically as the solar wind impacts us. Solar wind speeds are likely to be in excess of 600km/s and continue into the weekend, resulting in isolated G1 storm levels. Keep an eye on solarham.net for updates.

We are now at the spring equinox, so it is prime time for auroral activity. The spring equinox traditionally brings greater solar activity which results in an increased frequency of auroral displays.

It is also a prime time for north-south HF paths, such as the UK to South Africa, and the UK to South America.

Next week, the US Air Force predicts that the solar flux index will decline slightly to bring it into the range of 130 to 140. Once the weekend’s solar storm declines, we may expect a few days of relatively calm geomagnetic conditions before another period of unsettled space weather is predicted for Thursday the 30th and Friday the 31st. This could see the Kp index rise to five once again.

And now the VHF and up propagation news

The overall unsettled nature of the current weather pattern is likely to continue for much of the period through to the end of next week, except for a brief ridge of high pressure crossing the country after the weekend.

This might offer the only tropo potential for VHF operators. The rest of the time will probably be beset by bands of rain, showers and, at times, strong winds and introduce the prospect of some rain scatter on the GHz bands.

It’s a week to focus on fleeting tropo, rain scatter and aurora as modes of choice. As we said earlier, the aurora is worth looking out for since the solar conditions are still very disturbed. As usual, good indicators are the Kp index values, which ideally should be five or greater to get our attention.

The meteor shower calendar is still in its quiet period, and with no major showers to look for, it would be best to try your luck with random meteors, which tend to peak just before dawn.

The Sporadic-E season has not started yet but is getting closer, say from mid-April on 10m, perhaps.

For EME operators, Moon declination reaches maximum next Tuesday meaning long Moon availability windows. Path losses increase throughout the week and 144MHz sky noise starts out moderate, falling to low next weekend.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday 16th of March 2023

Last week was split in two, in terms of HF propagation. The first half of the week was characterised by excellent high-band conditions, with many people commenting on how good things were. The Kp index was low, there was a lack of solar flares and the solar flux index was high – perfect for HF.

There were reports of openings to Hawaii and Alaska on 10m and Bob, MD0CCE said 10m had been open to the Pacific every night for the last five or six days.

But it didn’t last and by Wednesday it all went pear-shaped.

The Earth was hit by a fast-solar wind with a southward-pointing Bz on Wednesday the 15th, which increased the Kp index to 5.67. Its impact on the ionosphere was quick and very damaging, to such an extent that the two ‘local’ Digisondes at Fairford and Chilton couldn’t detect the F2 layer, leaving their traces blank.

It happened again on Wednesday evening, with the Kp index hitting 5.67 once again.

Luckily, it didn’t last long and the Kp index was back down to less than two by the morning and the MUF over 3,000km was back over 28MHz by mid-morning on Thursday.

Next week, NOAA predicts that the solar flux index will remain in the range of 135 to 145. Unsettled geomagnetic conditions are forecast for the 20th but, as we know, anything can happen at this point in the solar cycle. Look for a low Kp index but, above all, get on the bands and see what you can work!

And now the VHF and up propagation news

The unsettled weather pattern seems likely to continue through the coming week driven by an undulating jet stream over the British Isles. This will mean, for yet another week, there is unlikely to be much good Tropo. It’s not all bad news though, since the unsettled part of the weather story may introduce some rain scatter on the GHz bands.

The mention of jet streams should, in a month or so, raise the promise of some Sporadic-E activity, which is often geographically related to the position of jet streams. It’s probably a bit early for that, although it could be worth considering a look at 10 and 6m as we move towards the end of the month.

10m, and 6m if you're in the far South West, can also give some good Trans Equatorial propagation, this time of year. This is typical of the changeover period from the southern hemisphere to northern hemisphere Sporadic-E activity.

As usual, the chance of aurora is still around, so keep a watch out on the clusters or spaceweather.com for all the latest news. Early-morning random meteors should stay on the checklist too.

For EME operators, moon declination is low but rising, going positive again on Wednesday meaning Moon availability windows will lengthen. The Moon is at perigee today, so path losses are at a minimum. 144MHz sky noise is low this week, apart from the whole of Tuesday when the Sun and Moon are close to an eclipse.

It is perhaps worth reminding new licensees that preparing a good list of HF and VHF beacons to monitor can be worthwhile, especially in quieter times before the summer Sporadic-E season gets underway.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday 9th of March 2023

It was business as usual last week with the solar flux index in the 180s, numerous C-class flares and, at the time of writing, 13 M-class flares over the past seven days.

The Kp index has been mostly settled for this part of the cycle, averaging two to three all week. But this doesn’t mean there has been little activity on the Sun, just that any eruptions have been directed away from Earth.

For example, a large prominence eruption off the Sun on the 7th of March resulted in a coronal mass ejection that stretched hundreds of thousands of kilometres into space.

It is this type of activity that makes space weather predictions difficult. If it had been Earth-facing, we could have ended up with a highly-raised Kp index and extensive aurora. As it was, the event had little or no effect on Earth.

Maximum usable frequencies continue to be high, but we are starting to see the effects of the Summer ionospheric changes that will see daytime MUFs decline.

The MUF over a 3,000km path often doesn’t exceed 28MHz now until later in the morning.

This is due to a seasonal change in the ionospheric chemistry and a shift from monatomic species to diatomic ones, which are harder to ionise.

So, make the most of 10m as by mid-summer we may lose long-range propagation on 28MHz, other than through Sporadic-E events.

We mentioned last week that this is a good time for North-South paths as we head towards the Spring equinox. That is, good paths to South Africa and South America are more likely now than they were a few months back. There have been a lot of stations on 10m in the late afternoon from South America so make the most of the propagation.

Next week, NOAA predicts similar solar flux index figures, with the SFI being in the range of 170 to 185. The Kp index is predicted to be at two or three, with perhaps more unsettled geomagnetic conditions on Wednesday the 15th.

As always, see solarham.net for more up-to-date information.

And now the VHF and up propagation news

The unsettled winter weather has yet to give way to spring, so it's primarily low-pressure systems and periods of rain or snow that we will be dealing with in the next week or so.

Whether it’s rain or snow, this unsettled pattern limits any Tropo options and leaves only GHz band rain-scatter as a propagation mode to explore. Generally speaking, the rain, or perhaps the point where the snow is melting as it falls, should provide better reflections, whereas, in very cold areas, where it is all snow, reflections may be weaker. This probably means that it will be southern areas that perform better with rain scatter.

For the next few weeks, there are no significant meteor showers and therefore the pre-dawn random meteors will be the best options. Aurora, on the other hand, tends to favour the spring and autumn months, so in view of the current state of solar activity, as mentioned in the previous section, you should continue to monitor the Kp index for signs of activity and check the bands if it gets to the point that Kp equals five.

For EME operators, after minimum declination this Thursday, Moon availability windows will start to lengthen. Path losses will continue to fall but we are still a week from the Moon’s perigee – its closest point to Earth. 144MHz sky noise is high, reaching over 2,800 Kelvin on Thursday.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 2nd of March 2023.

The auroral event last week was probably the strongest we've had in this solar cycle. There were widespread visible aurora reports from the UK on Sunday the 26th of February. The Kp index eventually hit seven at 0900 UTC on February 27th, sparking widespread visible aurora alerts all over the UK for Tuesday evening as well.

The solar wind speed gradually decreased to below 650km/s and the Bz component of the interplanetary magnetic field shifted to the north, bringing the Kp index down.

March is always a good, or bad, month for aurora, depending on your perspective. The aurora is at its most active around the equinoxes in March and September.

Active region 3234 also produced an M8.6 flare on the 28th, but as this was at 1750UTC, the radio blackout was restricted to the Americas. Any CME material was directed away from Earth.

The solar flux index remained in the range of 150 to 160 last week, which was enough to make the daytime maximum usable frequency remain above 28MHz most of the time, although the geomagnetic disturbance did have an effect and lowered it slightly.

Next week NOAA predicts the SFI will remain in the range of 145 to 165. A geomagnetic disturbance is predicted for the fifth to the seventh, which could see the Kp index hit five. So, watch out for visible aurora once again.

The period between the ninth to the fourteenth is predicted to be generally calm geomagnetically, so this might be the best time for DX on the upper HF bands.

However, as we know this is a difficult time for predictions, anything could happen. We suggest keeping an eye on solarham.net for updates.

And now the VHF and up propagation news

The very strong high pressure and tropo enhancement recently have. competed for attention with magnificent auroras, but we are now heading into quieter territory. The large high will decline early this weekend, ending the tropo bonus.

After which, the central weather theme is that of a colder northerly weather type with wintry showers, especially near windward coasts. This raises the prospect of rain scatter on the GHz bands.

After the recent dramatic solar-induced propagation week, it would be optimistic to expect a repeat, but the spring months are notable for producing auroras and there is always random meteor scatter. So, there are plenty of options to check up on in the coming week.

For EME operators, Moon declination is still high this weekend but we are on a downward trend, turning negative on Thursday, meaning Moon availability windows shortening all week.

With perigee last Friday, path losses will continue to fall. 144MHz sky noise is low all week. Perhaps you already view your radio-activity in the context of propagation conditions. But, for those not yet making this a routine, becoming aware of how these things are controlled can make a huge difference to your operating successes.

Why not start by seeking out some of the excellent propagation talks from radio clubs and the RSGB Convention which are often available online?

And that’s all from the propagation team this week.

GB2RS News

Sunday the 26th of February 2023

The news headlines:

• RSGB Board Update
• New RSGB Youth Champion
• Celebrating BBC Broadcasting in Scotland

The RSGB President Stewart Bryant, G3YSX has reported that due to the workload of the Board and the number of remaining members, the Board thought it prudent to ask Ian Shepherd, G4EVK to re-join the RSGB Board as a co-opted Director until the AGM. After the AGM and the elections, the Board will look at its membership and will likely make further co-options. The RSGB Company Secretary fulfils an important role in the AGM proceedings and so Stephen Purser, GW4SHF was asked to return to this role until the AGM, whilst the Society appoints a new Company Secretary through the usual process. If you are an RSGB Member and would be willing to undertake the duties of RSGB Company Secretary, or if you would like further information about the role, please contact the General Manager’s department via gm.dept@rsgb.org.uk

Liam Robbins, G5LDR has been appointed as the RSGB’s new Youth Champion. He gained his Foundation licence in 2021 and his Full licence in late 2022. Liam plans to encourage the use of amateur radio with local Scouts and he is also keen to revive radio societies at universities and colleges. He is eager to work with younger radio amateurs and to engage with outreach programmes that clubs are already running. Liam is looking forward to working with the current RSGB Youth Team.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 23rd of February 2023

Last week was characterised by many low- and medium-level solar flares. At the time of writing, in the past seven days, the Sun has emitted more than 60 C-class flares, six M-class flares and one X-class flare.

The X-class flare coincided with the measurement of the solar flux index meaning an erroneous reading of 343 was logged. The next day it was back to a more accurate 167.

The solar flux index has generally declined from the 200s we saw earlier in the month and stood at 152 on Thursday the 23rd. Nevertheless, daytime maximum usable frequencies over a 3,000km path still exceed 28MHz on a daily basis.

Geomagnetic conditions have been mixed with the Kp index hitting 4.67 on Thursday due to a fast solar wind.

We are heading towards the equinox period as we leave February next week and enter March. This is a time that favours North/South paths, such as the UK to South Africa and the UK to South America.

We’ll start to lose propagation to the USA on the higher bands as the Spring progresses, but don’t worry – it will be back in the Autumn!

A coronal hole is turning into an Earth-facing direction, which may cause some disruption with an increasing Kp index this weekend.

NOAA also predicts slightly worse conditions for the next week with the solar flux index declining to the 125-145 range. Unsettled conditions are predicted for the period of the 5th to the 7th of March, with the Kp index perhaps hitting five again.

As always, this is a guide as we are living in unpredictable times with regard to solar activity.

And now the VHF and up propagation news

The coming week looks likely to be another high-pressure period on the weather charts. As we ended this week, the high was offset to the west of Ireland but will become centred over Scotland with a colder north easterly over southern Britain.

This means that Tropo may become a mode of choice, particularly for northern areas, although this may well decline as a colder northerly starts at the end of next week. This could offer rain or snow showers with the chance of some associated GHz band scatter propagation.

As secondary options, aurora and meteor scatter remain viable, of course. Watch for a high Kp index for aurora and remember that random meteor scatter is always likely to be best around dawn.

For EME operators, the positive and rising Moon declination this week will see Moon availability windows lengthening until maximum declination on Wednesday. So, there will be high moon elevations, but path losses will continue to increase until apogee next Friday when the path loss trend will reverse.

144MHz sky noise is moderate to low for the rest of the week, only reaching 500 Kelvin on Tuesday and Wednesday.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 16th of February 2023

Last week was interesting as we had an X-class solar flare, and a significant geomagnetic disturbance, as well as good HF conditions at times.

An impulsive X1.1 solar flare was observed around active region 3217 in the southeast quadrant of the Sun at 1548UTC on the 11th of February. The flare did not appear eruptive, so we had no associated coronal mass ejection.

Nevertheless, the flare caused a fade-out as its X-rays penetrated deep into the D-layer of the ionosphere.

There were other lesser M-class and C-class flares throughout the week.

The Kp index rose to five on Wednesday the 15th of February and conditions continued to be geomagnetically unstable throughout Thursday. Nevertheless, the ionosphere remained relatively stable with daytime MUFs over 3,000km generally staying above 28MHz all week.

The critical frequency is generally remaining well above 4MHz until midnight, meaning 80m is open around the UK and also to DX. After midnight it can decline, meaning only longer paths are open.

NOAA has updated its coronal mass ejection forecast model to predict a stronger-than-anticipated solar wind passing Earth by late Friday the 17th of February and into Saturday the 18th. A moderate G2 level storm watch was officially added, beginning on Friday, so aurora sky watchers and VHF enthusiasts should be alert this weekend.

Next week, the Space Weather Prediction Centre forecasts that the SFI will fall back, perhaps to 130 by next Friday. Once we get past this weekend’s geomagnetic disturbance, the Kp index is predicted to remain settled all week, although a single coronal mass ejection could soon spoil that.

And now the VHF and up propagation news

After some good tropo for the 70cm UK Activity Contest last Tuesday, it will be a return to more unsettled weather that ends this week and starts this weekend. High pressure will then quickly return and take up residence over the south and west of the country, eventually ending up west of Ireland.

This will mean that tropo will again offer some enhanced conditions on VHF and UHF and may prove useful for the 1.3GHz UK Activity Contest on Tuesday evening.

After midweek, it will tend to favour paths within the UK and to the south into France. From midweek there will be low pressure to the east of the British Isles with a showery northerly flow down the North Sea. This will cut off the eastern half of Europe from any Tropo prospects, but it may offer some rain scatter from eastern areas.

There may continue to be some good chances of auroral propagation, which you can explore by checking the Kp index for values higher than five. In the absence of major meteor showers, random meteor scatter is always an option and likely to be most profitable around the dawn period.

For EME operators, Moon declination is negative but increasing, going positive again on Wednesday. The week will therefore see Moon availability windows increasing and path losses increasing from their lowest with perigee, the point where the Moon is closest to Earth, occurring today Sunday the 19th.

The Sun and Moon are close to an eclipse later today and throughout all of Monday’s moon window, so sky noise will be high due to the Sun being in the beamwidth of most antennas. After that, 144MHz sky noise is low for the rest of the week.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 9th of February 2023

The solar flux index rose again this week with the arrival of more sunspots. By Thursday, the SFI had reached 192, up from 135 the week before.

However, there has been some flare activity with minor C-class and some M-class flares, mainly from active region 3213. None of these has erupted in an Earthward direction so we’ve avoided coronal mass ejections and their effects.

The solar wind has been quite active, including long periods with a negative Bz and speeds of up to 600 kilometres per second. This has meant that the Kp index has remained relatively high, hovering around 3.5 for days.

All of this means that ionospheric conditions have been quite good with the daytime critical frequency over the UK generally above 9MHz. This means that paths over 3,000km have generally supported operations up to and beyond 10 metres.

At night, MUFs over 3,000km hover around 10MHz, especially in the hours just after sunset.

Next week, the US Air Force has the SFI remaining at around 195, before falling back to 150 by the 17th. Geomagnetic conditions should remain relatively settled unless we get a coronal mass ejection.

All in all, this is a good time for HF so get to it! And good luck with making contact with the 3Y0J Bouvet Island DXpedition.

And now the VHF and up propagation news

The large area of high pressure which has brought tropo to many parts of the British Isles looks good for a few more days. Some models suggest that Atlantic lows may move in after mid-week, so make the most of it before then.

Unfortunately, the northern parts of the country have seen windier weather at times and largely missed out on the best tropo, although with some chance of rain scatter to make up for it.

The aurora prospects and meteor scatter are still worth a check during the next week. Check aurora when the Kp index is high, and meteor scatter around dawn. Use the usual sources of information, such as clusters and band reports to get onto the bands at the right time.

For EME operators, Moon declination is negative, reaching a minimum on Thursday. EME Moon availability windows will be short. Path losses are at their lowest as the Moon approaches perigee next Sunday.

144MHz sky noise is moderate at the start of the week but increases to a high of over 3200 Kelvin next Thursday, the 16th.

And that’s all from the propagation team this week.

The news headlines:

• RSGB feature in The Times
• RSGB Convention videos
• British Science Week

The RSGB was delighted to see the feature in The Times on Saturday the 28th of January about amateur radio. It was a great opportunity to highlight both amateur radio and the Society in the mainstream media. Heather Parsons, the RSGB Communications Manager, spent a week liaising with Rhys Blakely, the Science Correspondent, and coordinating the interviewees. She put forward a whole range of ideas and possible interviewees and the RSGB would like to thank everyone who supported this opportunity, even though some contributions didn’t make it into the final piece. An external media monitoring agency has confirmed that the potential online audience for this feature was over 42 million. The feature is called “Ham radio tunes in to a new generation” and you can still read it online. Go to thetimes.co.uk and search for amateur radio.

The RSGB has just released another presentation from its 2022 Convention. Brian Coleman, G4NNS talks about The UK Meteor Beacon Project which is a collaborative project between the amateur radio and radio astronomy communities. The aim is to collect data on meteor events over the UK and Phase one was to establish a transmitting beacon. Phase two is to create a network of receivers to monitor the radio echoes from meteors and to stream data over the internet to support the study of meteor events and their impact on the ionosphere. The Project has received RSGB Legacy funds to help make this great idea happen. You can see the presentation on the RSGB YouTube channel and you can find out more about the RSGB Legacy funds on the Society’s website at rsgb.org/legacy

British Science Week, run by the British Science Association, is an annual event celebrating science, technology, engineering and maths. It provides a platform to support teachers, STEM professionals and the public in delivering STEM activities and events across the UK. This year’s theme is Connections, which lends itself perfectly to wireless communication and amateur radio-related activities! The RSGB has put together a set of activities suitable for children in Early Years, Primary and Secondary school. Several radio clubs from across the UK have already planned activities for British Science Week and the RSGB hopes its resources will inspire you to get involved too. Find out more on the RSGB website at rsgb.org/bsw

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 2nd of February 2023

Well, what a difference a few weeks make. On the 15th of January, the solar flux index was at 234 and the Sun was peppered with spots. This week, on Thursday, the SFI was at 134 and the solar surface looked like it was at sunspot minimum again.

The Sun has also been mainly geomagnetically quiet, with a maximum Kp index of 3.67 on Thursday, due to an elevated solar wind speed with a southward pointing Bz. We have only had relatively minor C-class solar flares to contend with.

Meanwhile, there is DX to be worked, especially on 10m which continues to shine.

The good news is that this lull in solar activity should come to an end, although the Space Weather Prediction Centre predicts that the SFI may only go up to 155 next week. Unfortunately, it also predicts disturbed geomagnetic conditions, especially from the 7th to the 10th.

With the daytime critical frequency, as measured at Chilton, reaching almost 9.7MHz at times, we are virtually guaranteed good conditions on all of the upper HF bands with 10m predicted to be open for contacts over 3,000km for most of the day. Night-time highs are set to reach 9 to 9.5MHz over 3,000km. So, all frequencies, except 7MHz and below, are likely to be closed to DX.

80m may also close to short-range or near vertical incidence skywave skip at night, leaving only continental and longer paths, such as southern England to Scotland, open. This should improve as we head into Spring.

And now the VHF and up propagation news

There is a continuing tendency for high pressure to dominate the weather charts and keep tropo on the agenda for much of the coming week, but with some caveats.

The position of the high is such that, as we end the current week, it’s over France and this puts us in a mild westerly flow with reasonable tropo propagation.

After this weekend, some weather models suggest a modest cold-air Atlantic high will arrive and will probably link with an intense high of more than 1050 millibars over western Russia. This may lead to a very cold easterly weather pattern over southern Britain by midweek with a chance of wintry weather and snow showers over eastern areas coming in from the North Sea.

This could be a good time to experiment with scatter propagation on the GHz bands. Note that winter showers generated over the sea are often twenty-four-seven phenomena rather than the traditional daytime showers used for rain scatter in the summer.

Keep trying other modes such as meteor scatter around dawn and aurora when the Kp index is high, but the high-pressure-driven modes will be the primary focus.

For EME operators, Moon declination is still high, not going negative again until Thursday. So, EME Moon availability windows will shorten and path losses will decrease as the week progresses. 144MHz sky noise is low all week, only reaching 350 Kelvin next Sunday.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 26th of January 2023

As of Thursday, we had a strange situation whereby all the current visible sunspots were in one hemisphere of the Sun. But this isn’t that unusual, as the two hemispheres usually peak at different times in the cycle.

In a couple of years, we may well have the reverse situation.

Nevertheless, the solar flux index declined and stood at 172 on the 26th when this report was prepared. While there are plenty of sunspots, they are all relatively small, unlike a week ago when active region 3190 was on the visible face.

Last week saw the Sun being settled geomagnetically, with the Kp index not exceeding three. We have had some M-class flares, but nothing stronger.

NOAA predicts that the solar flux index will decline to 175 before increasing again at the beginning of next month. We can expect quiet geomagnetic conditions for a time, but NOAA predicts that the Kp index will rise again around the 1st and then from the 7th to the 10th of February.

Meanwhile, the 3YOJ Bouvet Island DXpedition, located at 54.42 degrees South, 3.36 degrees East, is getting closer to its final location. So, it's time to start looking at propagation predictions for this sought-after entity. Bouvet lies almost exactly due south from the UK. If you have a beam point it at 180 degrees or 0 degrees for the long path.

The short path is likely to give you the best results, that is 80 to 100% reliability, with the 15m band open from 0800 to 2100UTC. There are shorter 12m and 10m openings during the day, with 10m open from 1200 to 1400UTC and again from 1700 to 1800UTC. 20m should give the best results overall from 1700 to 0200UTC, although it is likely to be the busiest band.

30m and 40m also offer up good propagation from 1700 to 0400UTC.

There is also a weaker long-path opening predicted on 17m from 1000UTC until 1600UTC with 50% probability. These were all calculated with VOACAP online and Proppy.

The UK appears to have good HF propagation to Bouvet overall but make sure you are on the right band at the right time!

And now the VHF and up propagation news

There has been some very focused tropo in the last week, especially on 70cm and 23cm digital modes around the edge of some high pressure from the UK into eastern Europe and the southern Baltic.

This shows the value of looking for paths along the edge of extensive highs, rather than across the centre, where the inversion dips lower and may duct the path into the ground.

The coming week offers further high-pressure systems, mostly over the Atlantic to the west of Britain or to the south. So, perhaps paths towards Spain or the Canary Islands are worth a look. The northern half of the charts will see deep lows, much stronger winds and rain or showers, so introducing rain scatter options and testing the antennas.

Other modes are available, of course, but the good practice of watching the clusters should keep everyone informed so that you don’t miss out.

It’s still worth a check for aurora, and random meteor scatter is always an option around dawn, even in the current meteor shower minimum period that lasts until the Lyrids in mid-to-late April.

With the Moon at peak declination on Thursday, this is a good week for EME with long Moon availability windows. That said, Moon apogee next Saturday means that EME path losses are high. 144MHz sky noise is moderate, reaching 500 Kelvin on Wednesday.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 20th of January 2023

The solar flux index has continued to remain above 200, which is good news for the upper HF bands.

10m continues to surprise people with 10m FM around 29.600MHz bringing transatlantic contacts to many. AM around 29.000MHz is also bringing some exciting contacts.

The Sun is currently peppered with spots, with the recent solar flux index of 234 being the highest since 2014. But solar flares and coronal mass ejections remain a threat. We have had numerous M-class flares over the week, but nothing stronger.

The Kp index hit four on Wednesday the 18th due to a glancing blow from a coronal mass ejection and we can expect it to rise again on Friday or Saturday due to an Earth-facing coronal hole.

The Chilton and Fairford ionosondes remain offline so please select Dourbes if using Propquest.co.uk. The critical frequency, as measured at Dourbes, remains above 7MHz from around sunrise onwards, giving a MUF over 3,000km of more than 30MHz for much of the day. So do make the most of 10m, which is probably at its best right now. Make hay, or DX contacts, while the Sun shines, as they say!

The good news is that the Space Weather Prediction Centre expects the solar flux index to remain above 200 for the next week. It says the Kp index might rise again to perhaps five on the 26th and 27th, but may otherwise be two to three in the early part of next week.

And now the VHF and up propagation news

The overall weather pattern remains rather changeable at first, but with a tendency to form high pressure, initially in the south, more generally after mid-week.

In terms of propagation, a welcome return of Tropo conditions is likely, although it may take a while to develop more widespread lift conditions. Sometimes it takes a high-pressure region to become a ‘cloudy high’ to give the best chances of widespread Tropo. Ideally, the high needs to be located such that cloudy Atlantic air can move in across the country underneath the temperature inversion.

It’s still worth a check for aurora, as the Sun is very active at the moment but it's probably a good time to put away Sporadic-E thoughts until the spring.

Random meteor scatter is always an option around dawn, but we are now into the meteor shower minimum period that lasts until the Lyrids in mid-to-late April.

Yesterday’s Moon perigee means that EME path losses are at their lowest but will slowly rise throughout the week. Declination is rising and goes positive on Thursday so Moon availability windows will lengthen. 144MHz sky noise is low all week, only going much above 300 Kelvin next Saturday.

And that’s all from the propagation team this week.

After several months of restoration and development, a Wheatstone Tape Perforator and Wheatstone High-Speed Morse Transmitter have gone on display in the RSGB’s National Radio Centre at Bletchley Park. Used extensively from the 1940s until at least the late 1960s such systems enabled the transmission of Morse signals either via telegraph or by wireless at consistently high speeds, without errors, such that might have been introduced by hand-sent Morse. The display is connected to an audio oscillator so, with a push button on the outside of the display case, visitors are able to start the transmitter, see the paper tape being read, and hear Morse characters being sent.

The RSGB’s National Radio Centre at Bletchley Park is looking to create a new wall display, illustrating some simple radio set-ups, to inspire newcomers to get started in amateur radio. If you would like to have a photo of your radio shack on display, please send in a good-quality image, showing you operating your radio, or your radio bench. The radio shack could be located anywhere from your loft, to your back bedroom, garden shed, car or on a mountaintop. Remember, the point of this project is to inspire people to get started in the hobby, so the photos need to show a diverse mix of operators and the radio set-up shouldn’t be overly complex. The most suitable photos will be selected and a montage display created, with the title: Take a look at my radio station. If you would like to enter, send your photos to: nrc.support@rsgb.org.uk

The Online Amateur Radio Community provides amateur radio licence training via Zoom. The next Intermediate course is due to commence during the first week of February. The course, which costs £5 to join, will run for eight weeks. The next Full licence training course will start on Wednesday the 17th of April and run for nine weeks. The fee for the Full course is also £5. For further information please visit www.oarc.uk

The GB2RS news service would like to increase the coverage of VHF FM and SSB broadcasts in Northern Ireland. Applicants must be an RSGB member holding a Full or Intermediate licence. If you would like to find out more, without obligation, please get in touch with the GB2RS News Manager, Steve G4HPE, via gb2rs.manager@rsgb.org.uk More information about the RSGB’s news service can be found at rsgb.org/gb2rsschedule

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 13th of January 2023

It seems X-class solar flares appear like buses; you wait for ages and then three turn up at once! Over the last week, we have had X-class flares on the 7th, 9th and 10th.

The latest, at the time of writing, saw sunspot region 3186 rotate into view off the Sun’s northeast limb and produce an X1.0 solar flare at 2247UTC on the 10th. It may have thrown some plasma into space in the form of a coronal mass ejection but, as it is not yet directly facing Earth, any associated coronal mass ejection was likely directed away from us.

Over the coming days, it will become Earth-facing and more activity is expected, with sudden ionospheric disturbances and coronal mass ejections becoming the norm. If this does occur, expect the MUF to take a dive, perhaps only for 20 minutes to an hour, if X-ray radiation from a flare impacts us, and for a day or so if a coronal mass ejection hits us.

So, although we currently have an SFI in the 190s, it will be hit-and-miss as to whether HF propagation will be good or bad. The best advice is to monitor the bands and don’t be surprised if we have some fallow days if the Kp index rises.

Excitement is building as the 3Y0J Bouvet DXpedition team is on its way. At the time of writing, they had reached Cape Verde en route to the Falkland Islands. Then they have a long boat trip with departure estimated for the 14th of January. Depending on the weather, expect them to be operating from late January for 22 days. We’ll take a close look at HF propagation to Bouvet in a later GB2RS report.

Meanwhile, NOAA predicts that the solar flux index is unlikely to remain as high as it is. It says it may drop into the 150s, although its predictions haven’t been too accurate recently. Nevertheless, 150 is still admirable. Let’s hope that the Kp index stays low to give the best hope of DX on the upper HF bands.

And now the VHF and up propagation news

The unsettled weather pattern remains in place for the coming week and the main changes concern a deeper low in the sequence being strong enough to bring a temporary burst of colder northerlies.

This seems possible later this weekend and early next week. In terms of propagation, it’s looking like rain- or snow-scatter for the GHz bands will be the more likely mode. There is a possibility of some high pressure to the south after mid-week, over France and Biscay, but only reachable from the southern fringes of the British Isles with very limited tropo options.

There has been some strong Sporadic-E showing on the Dourbes graphs on propquest.co.uk on occasion, but we are coming towards the end of the mid-winter Es window this week.

Random meteor scatter and aurora are both options this week. The minor Gamma-Ursae-Minorids meteor shower reaches a low maximum on the 18th. As usual, look to benefit from the pre-dawn peak of random meteors.

The Sun is very disturbed, so you’ll need to track the daily behaviour of the Kp index for aurora prospects. Ideally, it should be five or preferably higher for aurora.

The Moon reaches maximum negative declination this coming Thursday, and at perigee on Saturday, so EME path losses are low and Moon availability windows are short. 144MHz sky noise increases all week, peaking at over 2000 Kelvin on Thursday.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 6th of January 2023

Firstly, a happy New Year to all our listeners. Let’s hope that the propagation gods continue to smile on us in 2023!

The solar flux index is back near the 150 mark having seen a low of 128 on December the 23rd and a recent high of 165 on New Year’s eve.

Geomagnetic conditions had been mainly settled. That was until the Kp index hit five on the fourth thanks to a fast-moving enhanced solar wind. This may have come from an Earth-facing coronal hole on the Sun’s equator.

Propagation-wise, conditions have been good, but not exceptional. The main DX station on the bands has been Thierry, FT8WW on Crozet Island off the coast of South Africa. Thierry has been very active on FT8 and CW, but the pileups have been massive.

Next week, NOAA predicts that the solar flux index will remain in the range of 140-150. Geomagnetic conditions should remain quiet with no visible coronal holes coming into view at the time of writing. Expect the Kp index to be around two to three.

And finally, don’t forget the low bands, including 160 and 80 metres, which tend to come into their own at this time of year. Look for a night-time path between the UK and the DX, and also consider enhancements just before sunrise for signals from the West.

And now the VHF and up propagation news

The main weather theme for the next week is once again a continuation of low-pressure systems crossing the country with periods of strong winds and rain.

This suggests that tropo produced by high pressure will not feature again this week. It does, however, make rain scatter a possibility on the GHz bands, either from active frontal systems or from showery weather that these systems bring.

The unsettled weather is being driven by an active jet stream pattern, which offers good opportunity for ‘out of season’ Sporadic-E triggers, particularly towards Italy and round to Scandinavia.

These are very rare events in winter, but it will be possible to pick up signs of some Es on thePropquest.co.uk foEs plots on some days. So, don’t give up hope and monitor the clusters up to the middle of the month, at least.

The disturbed solar conditions put aurora a bit higher up the agenda this week.

For meteor scatter enthusiasts, last week’s two-hour outburst of the Quadrantids shower was the ‘last hurrah’ of showers until the late April Lyrids.

We are entering the annual ‘lull’ in shower activity, with just the minor Gamma-Ursae-Minorids active from the 10th of January to the 22nd reaching a low maximum on the 18th. Look to benefit from the pre-dawn peak of random meteors.

The Moon is at apogee today, Sunday, and declination is positive until late next Friday. Moon windows will slowly shorten and zenith angles decrease, while EME path losses decrease. 144MHz sky noise is low all week.

And that’s all from the propagation team this week.

Season’s greetings to all our listeners! Today’s GB2RS news script will the final one of 2022. Today’s news reading is optional, as the RSGB appreciates that not all newsreaders will be available as normal, but the script will be on the RGSB website so all can see it. We’d like to take this opportunity to thank all the newsreaders, who read the news on a variety of platforms, for their service to their fellow amateurs throughout the year. We’d also like to remind amateurs that there is a long-standing convention to listen for news broadcasts on Sundays before transmitting to allow news reading to go ahead without interference. Thank you to all those who listen on Sunday mornings, and the other times that the news is read, to those who call in afterwards to speak to the newsreaders, and to everyone who listens via various platforms. Please note, there will be no script prepared for broadcast on Sunday the 1st of January 2023 due to RSGB HQ being closed from 12.30pm on Friday the 23rd of December until 8.30am on Tuesday the 3rd of January 2023. Newsreaders may, of course, choose to run a net at their normal transmission time, but under their own callsign only.

The RSGB is making plans to celebrate the coronation of King Charles III and the Queen Consort in May 2023. The Coronation theme is looking towards the future while being rooted in our traditions, which the Society would like to incorporate in its celebrations. The UK has an ancient chain of fire-based beacons and the RSGB is considering ways that these might be used in the plans. As well as organising events for radio amateurs, this is a great opportunity to demonstrate amateur radio to the public and to gain publicity in the media. If you have any thoughts about how to use the fire beacon chain, or if you have ideas for activities on the Coronation theme that could be used as outreach to the public, please contact the RSGB Coronation Lead, Alan Messenger, G0TLK on special.projects@rsgb.org.uk

Are you keen to see amateur radio thrive? Do you have the time and enthusiasm to support other radio amateurs and to help shape the RSGB of the future?

The solar flux index stayed around 150 over the last week, bringing some choice DX to the higher HF bands. However, solar flares continue to plague us, bringing short-lived band fade-outs at times. These have all been moderate C- and M-class flares. It is uncertain as to whether or not there will be an X-class flare soon.

Meanwhile, try and work some Arctic Circle DX. Santa’s broadcasting arm, Santa Radio, OF9X, will be active again, on all amateur radio bands, using CW, SSB and digital modes until the end of the year.

On any band, from 10MHz and up, it should be fine to make contact with OF9X during the day, with 80m and 40m being ideal for night-time contact. The DX cluster is probably the best way to find where they are operating.

NOAA predicts that the solar flux may decline slightly over the next week, perhaps going down to 125. But then it should rebound, maybe making it to 160 by the first week of January.

Unfortunately, solarham.com is currently offline. Kevin, VE3EN, who produces the site, says that hopefully this downtime will be short-lived. Keep an eye on the URL as it remains one of the most useful sites for radio amateurs.

And now the VHF and up propagation news

There will be a very unsettled flavour to the Christmas propagation weather with many lows tracking across the country into the New Year. There will be spells of strong winds to provide a few nail-biting moments for antennas, but the main theme is for bands of rain and heavy showers. These will be capable of producing some rain scatter on the GHz bands on most days in one part of the country or another. Cold air will be present at times to give some snow scatter in places, although primarily over northern Britain.

The chances of traditional high-pressure systems bringing some festive tropo are very low indeed with the nearest high displaced well away over southeast Europe. The solar conditions will doubtless be worth considering as a possible indicator of auroral propagation if the Kp index rises above about five or six.

Mid-winter Sporadic-E, can surprise us over the period from now to roughly mid-January. A good example was shown on the Dourbes ionosonde on Monday the 19th of December when the Sporadic-E critical frequency reached 5.45MHz at 2300UTC and coincided with a jet stream nearby.

There will be plenty of jet stream activity, so it is well worth checking the clusters. Don’t be too fixed upon the usual times for Sporadic-E since these events tend to be driven by the timing of significant weather features.

For meteor scatter enthusiasts, the Leonis Minorids are still active but past their maximum, so we await the Quadrantids to peak with a zenithal hourly rate of around 120 between the 3rd and 4th of January.

Unlike other meteor showers that tend to stay at their peak for about two days, the peak period of the Quadrantids lasts only a few hours.

Moon declination is rising, so Moon windows will continue to lengthen, and zenith angles increase, while EME path losses increase after Christmas Eve’s perigee. 144MHz sky noise is low all week.

And that’s all from the propagation team this week.

Now the contest news

The UK Six Metre Group Winter Marathon began on Thursday the 1st of December. The contest will run until the 31st of January 2023. Using all modes on the 6m band, the exchange is signal report and locator.

Today, the 18th of December, the Stew Perry Top Band Challenge will end its 24-hour run at 1500UTC. Using CW on the 160m band, the exchange is your four-character locator.

On Tuesday the 20th of December, the 1.3GHz UK Activity Contest runs from 2000 to 2230UTC. Using all modes on the 1.3GHz band, the exchange is signal report, serial number and locator.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 16th of December 2022

Things hotted up last week with a healthy increase in sunspot activity. The number of sunspots ramped up, giving us a solar flux index of 165 by Thursday.

The other upside was the fact that geomagnetic conditions were quite settled with the Kp index remaining between one and three all week.

There were some downsides. We have had an increase in the number of solar flares, with a total of 14. Of these, 11 were M-class. This is all happening around active region 3165, which is now a prime candidate for an X-class solar flare, the most powerful.

There were reports of poor HF propagation on the morning of the 15th, which can possibly be attributed to the solar flares on the Sun. The graph of the maximum useable frequency, measured at Dourbes, looks rather like a roller coaster ride, with the extrapolated MUF over 3,000km being more than 38MHz at 9.15am and below 19MHz 20 minutes later.

The moral of this story is that if HF propagation seems to fail just give it 20 minutes and see if it recovers.

According to NOAA, the high solar flux index won’t continue for much longer. It predicts that the SFI will reduce to between 115 and 120. The Kp is also predicted to stay low, at least until the 22nd when it is forecast to rise to five, possibly because of a returning coronal hole from 27 days ago.

And finally, both the Chilton and Fairford Digisondes are offline at the moment, so please select Dourbes if using Propquest.co.uk

And now the VHF and up propagation news

The cold weather will be displaced as a temporary mild spell brings higher temperatures, plus wet and windy weather, during this weekend.

Eventually, colder westerly air with showery troughs will return from the west, but still with further bands of rain. There will probably be some good rain and snow scatter opportunities for the GHz bands. Tropo looks a bit thin, although there may be a brief enhancement on Sunday morning to France and the Low Countries but this will be gone by the afternoon.

The other modes like meteor scatter and aurora are still a consideration, but much less predictable.

With the Geminids meteor shower past its peak, there are two minor showers to look out for this week.

The Leonis Minorids are active from the 5th of December to the 4th of February, reaching a maximum on the 20th of December with a low Zenithal Hourly Rate, or ZHR, of around five. The Ursids are active from the 17th of December to the 26th of December reaching a maximum on the 22nd of December, also with a low ZHR of around 10.

Moon declination went negative on the 17th, so Moon windows will continue to shorten and zenith angles decrease. EME path losses are falling as we head towards perigee on Christmas Eve. 144MHz sky noise is increasing all week and on Friday we get close to an eclipse, so it will be very high during the whole Moon pass.

Lastly, to repeat the ‘heads up’ from last week about midwinter Sporadic-E, it is still worth mentioning since it usually becomes a reference after the event, and it would be nice to be there before it happens!

So, employ the usual check of HF and VHF clusters from 10 to 4m and use www.propquest.co.uk and its EPI or Es probability index plots to see where the most likely areas for Es are located.

Like summer events, rarer mid-winter Es are often associated with powerful jet streams and this unsettled weather is a good source for these.

And that’s all from the propagation team this week.

The RSGB is calling for volunteers who are willing and able to give their time and enthusiasm to ensure the Society continues to develop and thrive. This year there are nine roles to be filled and the results will be announced at the RSGB’s AGM in April 2023. An explanation of how to apply for the Nominated Board Director process, as well as the candidate packs and forms for President, Elected Board Director and Regional Representative, are all on the Society’s website at rsgb.org/election

At the end of September 2022, the Australian Communications and Media Authority, or ACMA, proposed that Australia’s amateur radio operators move to a class-based licensing scheme in July 2023, opening a consultation period that closed at the end of November 2022. The Wireless Institute of Australia has replied to the ACMA proposals with a comprehensive evidence-based response. The ACMA proposes moving Australia’s radio amateurs from individual apparatus licences to one licence for the amateur service as a whole. The principal reason cited is a reduction in the administrative burden for both the ACMA and the amateur radio community. The immediate benefit would be that licence and licence-renewal fees would disappear. The Wireless Institute of Australia’s response to the consultation can be found at tinyurl.com/WIAsubm

The RSGB National Radio Centre at Bletchley Park is pleased to announce that it will be hosting GB22YOTA on Saturday the 17th of December.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 9th of December 2022

There’s an old Chinese curse that says: “May you live in interesting times”. Well, the last week has been very interesting from an HF propagation perspective!

The solar flux index increased from 111 on the 30th of November, to 148 on Thursday the 8th. During that time, we had more than 50 C-class solar flares and two M-class flares, while the Kp index ranged from one to five. So, it’s been a bit like having all four seasons in one week!

HF propagation has varied dramatically as a result, with round-the-world echoes and spotlight propagation being very prevalent at times. Spotlight propagation is defined as a small geographic area that is favoured with good propagation at any given time.

The Norfolk Amateur Radio Club operated G6ZZ for 48 hours as part of the transatlantic centenary celebrations and worked more than 1,500 stations. Station manager Chris, G0DWV reports his highlights as: “Hearing my own echo as the signal went around the world on several occasions, being called by VK, Australia, and ZL, New Zealand, at 5/9+30dB with no one else on the band. And hearing echoes that made it impossible to understand the caller's voice.”

At the moment, it seems like it would be easy to dismiss an HF band as being closed when it could be wide open half an hour later.

The Sun is currently peppered with spots of all sizes. The USAF predicts that the good conditions could continue for a few days yet, with the solar flux index falling from 150 on Sunday to 110 by the end of the week.

Calm geomagnetic conditions may continue and there are currently no coronal holes in view. But please note that it only takes a single coronal mass ejection to spoil things.

And don’t forget that the low bands come into their own in Winter as well. This is a good time to look for DX on 160, 80 and 40 metres, especially in the late afternoon, after dark and at sunrise.

And now the VHF and up propagation news

This week’s VHF propagation highlight is the Geminids meteor shower. This is predicted to reach a broad peak over several days on either side of 1300UTC on the 14th of December.

The Geminids zenithal hourly record has reached 140-150 in all recent years so expect a good one with SSB QSOs possible for the better-equipped stations using good operating techniques, and the chance of 70cm digimode QSOs as well. The broad peak has a habit of declining quite quickly once it’s over.

In this present turn to cold winter conditions, prospects for high pressure and tropo are looking limited, apart from a weak ridge over northern Britain. Although even this is not a strong player.

Current weather conditions may appeal to the experimentally minded. Intense cold and snow-covered ground can produce strong shallow surface temperature inversions, so there may be interesting tests to be done in some parts of the country. Also, watch out for snow scatter on the high GHz bands if you see snowstorms around.

The solar-driven conditions mentioned in the previous section suggest that further possibilities exist for auroral propagation, given a high Kp index.

The dearth of Sporadic-E during the autumn months usually has a brief respite around this time of the year from mid-December to mid-January. It's very random but follow the usual summer routine of checking the clusters and maps to select the right directions. Although these isolated events can occur at the usual afternoon or evening times for Es, they can and do crop up in the morning and around the middle of the day.

Moon declination is positive but decreasing this week so Moon windows will shorten and zenith angles decrease. Path losses are at their highest with the Moon at apogee on Sunday night. 144MHz sky noise is low all week.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 2nd of December 2022

Last week was characterised by unsettled geomagnetic conditions that had not been forecast.

The Kp index fluctuated between three and five nearly all week, resulting in reduced HF propagation, especially over polar paths. The solar wind just refused to abate with speeds over 600km/s being commonplace. A southward-facing Bz interplanetary magnetic field just added to the problems.

In the CQ Worldwide CW contest last weekend, signals from the west coast and Midwest were badly affected, with one station in Colorado sounding very fluttery and weak. Strong aurorae were also recorded in the polar regions.

Nevertheless, some good scores were made in the contest. It was a case of making do with what was available, HF propagation-wise!

By Thursday, the Fairford Digisonde was reporting F2-layer critical frequencies in the region of 10MHz, with an extrapolated MUF over 3,000km well above 28MHz around noon.

Sunspots remained on the decline all week with the solar flux index struggling to get to 110. But the good news is that could now all change. Solarham.net reports that the beginning of December will see a potential influx of sunspots.

A new active region is now beginning to turn into view off the southeast limb and was the source of a number of minor C-Flares on Wednesday.

In addition to this, old regions 3140, 3141 and 3145 from earlier in November are about to turn back into view from behind the northeast limb.

NOAA predicts the solar flux index could increase to 120-125 next week, which would be a welcome upturn. We may also be entering a more settled phase with regard to the Kp index too, with NOAA predicting a maximum index of two or three all week.

However, a solar coronal hole will become Earth-facing on Saturday, so we expect the Kp index to rise perhaps late Sunday or Monday.

The ionosonde data server in the States, for the Propquest foF2 graphs, is still having problems, but it is being worked on. In the meantime, you will see a backup plot from Fairford to keep things going.

And now the VHF and up propagation news

The main weather theme for the coming week is that of colder north-easterly winds, but with some high pressure off the North West to give a chance of slightly enhanced Tropo, at first in western Britain. This will probably be spoiled, in eastern areas, by showers coming in from the North Sea.

GHz band rain-scatter options with the North Sea showers should be worth considering but, on this occasion, the showers may be relatively limited. So, don’t expect too much.

The solar conditions are still showing signs of activity, which can bring some VHF propagation options, such as aurora on 6m to 2m given a good trigger. So, look for high Kp indices above about five or six to make it worth checking.

Meteor scatter is, of course, an ever-present option for surprising us with any random activity. These sporadic meteors are more frequent around dawn, and the big Geminids shower in December is less than a fortnight away.

Moon declination is positive and increasing this week. So, Moon windows will lengthen and zenith angles will increase. Path losses are high and increasing this week. 144MHz sky noise is low to moderate, reaching 500 Kelvin next Friday.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday 25th November 2022

We dodged a bullet last week when a large coronal hole failed to produce a geomagnetic disturbance. Despite many predictions that we could expect an upturn in the Kp index, it looks like the solar wind missed the Earth, probably because the hole was too low in the Sun’s southern hemisphere.

As a result the Kp index never went higher than 4, actually 3.67 globally, and things remained calm. This was good news for HF, although a low solar flux index below 120 all week was nothing to get excited about. At the same time, the improvement in low-band conditions, as we head into late Autumn, is making up for it. Top Band contacts have been recorded with 3B8 Mauritius, and Peter, G3PHO has even made it into the USA in the late afternoon on 160m FT8.

So, if you’ve never worked much on Top Band, and you have the antenna for it, give it a try. Failing that, try the top end of 80m SSB around sunrise in the UK for contacts with the USA.

Next week, NOAA predicts that the solar flux index will remain around the 120-125 mark. The good news is that there are no large coronal holes currently visible and there have only been minor C-class flares with CMEs that have not been Earth-directed, so geomagnetic conditions are likely to be good. That is, at least until the 1st of December when we have a predicted Kp index of four, which may disrupt contacts mainly on polar paths.

This is good news for this weekend’s CQ Worldwide CW contest, which is a great opportunity for you to up your country totals or for your Worked All States award.

Now a footnote for those occasions when the propquest.co.uk graphs are not updating. It can be a local effect at one of the stations, such as Chilton, which has been offline recently. Usually selecting one of the tick boxes in the top right of the graphs will show Fairford or Dourbes when available.

However, last week and maybe still, we have a complete blank for all three ionosonde station plots, which is much more likely to be a server issue in the States where the data is hosted. You can check the Propquest server is working by selecting the “Archive” or “Averages” tabs. In any event, the ionosonde data plots will come back automatically once any issues have been resolved.

And now the VHF and up propagation news

The unsettled spell of weather continues into the first half of next week so could provide some further rain scatter opportunities on the GHz Bands.

The broad south-westerly pattern may well switch over to an easterly after midweek as high pressure builds across Scotland. This could bring a return of Tropo for some parts, but looks a bit weak, while the south will continue to be affected by low-pressure systems.

It will feel colder, with some models hinting at wintry conditions being a possibility, so wrap up well if you plan to do any portable operation!

The Alpha Monocerotids meteor shower noted last week is over but the small November Orionids, active until the 6th of December, reaches its peak on Monday the 28th.

Get ready for the big Geminids meteor shower in December. It commences on the 4th reaching a ZHR of over 100 between the 14th and 15th. More about this closer to the shower peak.

Moon declination is increasing again and goes positive on Friday. So Moon windows will lengthen and zenith angles will increase. Path losses, on the other hand, start to increase again this week after last Friday’s perigee. We have to wait until mid-2026 before maximum declination coincides with the lowest path loss, but we are moving in that direction again. 144MHz sky noise is low all week, not getting above 300 Kelvin until next Sunday.

And that’s all from the propagation team this week.

Most of you will have experienced RF interference problems of one sort or another over the years. In this world of advanced digital technology and increasing wireless connectivity, the probability of interference is high and increasing rapidly. This is giving rise to an ever-increasing pollution of the radio spectrum which is threatening all wireless communication. To counter these problems, the RSGB EMC Committee makes the relevant authorities aware of issues by taking measurements and surveying any available documents and reports. The committee needs volunteers to help with that task. Deep technical knowledge or experience in EMC work is not necessary, but ideally, candidates should have a good understanding of radio. If you are an RSGB member and would like to help, please contact emc.chairman@rsgb.org.uk

The RSGB’s National Radio Centre at Bletchley Park will be closed from Tuesday the 22nd of November until Friday the 25th of November for the upgrading of essential equipment and the installation of a new fire alarm system. The Society apologises for any inconvenience this causes.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 18th of November 2022.

The good HF conditions continued last week with a low Kp index and a reasonable solar flux. But is that all about to change?

The problem is a large coronal hole in the Sun’s southern hemisphere, which became geoeffective on Thursday. The hole is at mid-latitude, so is not completely in line with Earth. But its large size means that we could see a strong solar wind, which may hit the Earth this weekend, potentially pushing the Kp index up for a couple of days at least.

Sunspots have been adequate rather than outstanding. The main active groups have now rotated out of view, but there are some new ones just appearing over the Sun’s limb.

The HF bands have been excellent and many newer amateurs have had their first taste of 10m in full flow.

Next week NOAA predicts that the solar flux index could decline to the range 105-115. The Kp index is predicted to rise to four at least until the 22nd. We may then get respite for a day or two before it rises again to three or four.

In other words, we have probably seen the best of the settled HF conditions for a while. Just what effect the enhanced solar wind and increased Kp index this weekend will have on maximum usable frequencies is hard to predict.

Typically, an increased Kp index can result in reduced MUFs, but whether we will see it impact 10 metres, especially with the predicted lower SFI, we will just have to wait and see.

And now the VHF and up propagation news

After last weekend’s excellent tropo, with 24GHz propagation from the South East of England to the near continent, we now have a seemingly never-ending period of unsettled weather continuing through the coming week.

This is driven by a strong jet stream flow across the Atlantic. Since it’s a low pressure and rain scatter period once again, it’s worth a reminder that, although we are way out of season with regards to Sporadic-E, it can still be seen on the foEs graphs on the Propquest.co.uk website and can be particularly useful for the LF bands.

Focusing back on VHF and above, the prevalence of low pressure during the week suggests Tropo is unlikely to entertain us. The only modes remaining to discuss are meteor scatter as we slowly fade from the peak of the Leonids, and finally the prospect of a random aurora if we have further disturbed solar conditions.

This week’s active meteor showers are the Alpha Monocerotids which are active until November the 25th and reach a low ZHR maximum on Monday the 21st of November. Also, the November Orionids, are active until December the 6th but don’t peak until the 28th.

Moon declination went negative on Saturday so Moon windows will shorten and zenith angles decrease. Path losses are still low but with perigee on Friday, path losses will fall all week. 144MHz sky noise slowly increases, reaching a maximum of over 2,500 Kelvin on Friday.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 11th of November 2022

Last week was a mixed bag in terms of space weather. Yes, the solar flux index increased to 138 by Thursday the 10th, but at the same time, we had a fast solar wind and a solar flare from active region AR 3141 to contend with.

The Kp index hit five on Monday the 7th after a prolonged period with the Bz component of the interplanetary magnetic field pointing south. When the Bz points south it more easily couples with the Earth's magnetic field, allowing solar plasma to flood in.

The Bz component of the IMF then shifted north, which helped conditions improve over the week. In fact, the Kp index was down to zero for the latter half of Wednesday and Thursday.

With no coronal holes, this was about as good as it could get for HF and the bands didn’t disappoint. The MUF over a 3,000km path reached 38MHz around lunchtime on Thursday. DX worked from the UK including A35GC in Tonga, 7X3WPL in Algeria and P29RO in Papua New Guinea.

The KQ2H 10m FM repeater on 29.620MHz is acting like a beacon this Autumn, often hitting S9 plus in the early afternoon. Running 1.5kW from the Catskill Mountains in upstate New York, it is a good indicator of trans-Atlantic conditions.

Next week NOAA predicts that the solar flux index will decline a little, placing it in the region of 120. Geomagnetic conditions may remain settled, at least until the 18th when NOAA predicts the Kp index could rise to five.

That said, it would only take a solar flare, and associated coronal mass ejection, from one of the large sunspots visible at the moment to spoil things.

And now the VHF and up propagation news

The main weather theme for this weekend is the very long moist airflow from the Azores to the UK and onwards to western Scandinavia.

Because high pressure will be just to the east of the UK at first this will probably lead to some potentially long-range Tropo conditions from western Europe down to the Canaries and Spain/Portugal.

A cold front will probably cut the Azores out of the best conditions. However, we should also be able to make use of good conditions into Europe and particularly across the North Sea to southern Scandinavia and perhaps parts of the Baltic.

All this is fine until the next change-over to unsettled weather rolls in from the Atlantic on Monday night and during Tuesday. After then, it will be windy with rain or showers and a small chance of some fast-moving rain-scatter from heavy showers.

The Leonids meteor shower peaks on Thursday the 17th, plus expect an encounter with a dust trail on November the 19th. It’s predicted to occur at around 0600UTC with a short-lived high ZHR between 50 and 200, but activity level is uncertain.

This is a good week to check out meteor scatter options and there have continued to be some occasional reminders that the solar conditions are capable of sending some higher Kp indices our way with an attendant chance of auroral conditions, so stay alert to the Kp index values.

The Moon is at maximum declination so we have long Moon windows and zenith angles up to 65 degrees in the UK. Path losses are still low but with apogee today, path losses are at their highest. 144MHz sky noise is low all week.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO

They write, we had yet another week of good HF propagation, despite a strong solar wind that threatened to push the geomagnetic Kp index up, but it generally never managed more than a four in the first half of the week.

The solar flux index managed to hit 130 on Thursday, having been in the 120s all week, but the sunspots have been quite weak and small.

On Thursday the Kp index rose again, hitting five due to the enhanced solar wind from an Earth-facing coronal hole. Nevertheless, the Fairford Digisonde registered a critical frequency of 9.925MHz, giving a maximum useable frequency in excess of 35MHz over a 3,000km path around lunchtime. This may have been a pre-auroral enhancement as it didn’t last very long – the MUF was soon down to 28.8MHz. Please note the Chilton Digisonde has been down again, so if this continues please switch to Fairford at Propquest.co.uk.

The upper HF bands have been very lively with much DX being worked. 5V7RU Russian DXpedition team in Togo have made it into many logs, as has J28MD team in Djibouti.

Transatlantic 10m signals remain very strong during the daylight, reflecting the good HF propagation at this point in the year, switching to South America as the Sun is setting.

Next week, NOAA predicts that the solar flux index will probably remain in the 120s. It also predicts unsettled geomagnetic conditions on the 10th, 11th and 12th when the Kp index may once again rise to five.

If you have been putting off getting onto HF you are really missing out!

Now the VHF and up propagation news.

The unsettled weather pattern is still the dominant story for the coming week with a series of lows either across the country or sitting over the nearby Atlantic, bringing periods of rain and strong winds and showery interludes in between.

This raises the issue of rain scatter for another week on the GHz bands. There are probably just two periods with ridges of higher pressure. The first crosses the country on Friday night at the start of the week and the second develops over the English Channel at the end of next week, so limited Tropo options once again.

November is a good month for meteor scatter with the Leonids shower starting today and peaking around the 16th. Expect some increasing signs of meteor scatter activity as the week progresses.

The solar conditions continue to provide coronal holes and the prospect of geomagnetic storms, so keep a watch on the Kp index, with a high index warning of auroras.

As for Sporadic-E, we are in the doldrum month of November which rarely provides anything dramatic, but the usual procedure of monitoring the foEs graphs on Propquest should reveal what's happening.

Moon declination is positive again with Moon windows lengthening as the week progresses. Path losses are still low but increasing and apogee is still over a week away. 144MHz sky noise is low in the coming week.

And that’s all from the propagation team this week.

The RSGB VHF Contest Committee is currently planning the rules for next year’s VHF contests. Following some discussion at the RSGB Convention, they have some questions on which they would appreciate feedback from contestants. You can find the survey online at thersgb.org/go/vhf2023. The survey will close on Sunday the 13th of November.

The RSGB is sad to learn of the passing of Richard Brunton, G4TUT. For countless years, Richard was editor of the popular Southgate Amateur Radio News website. Every single day, he searched the world’s amateur radio and technology resources for stories of interest and published them. Richard offered his platform inclusively, commissioning non-commercial podcasts and blogs to promote opinion alongside conventional news items. He also compiled the ‘CQ Serenade’ weekly programme which was broadcast throughout Europe on Shortwaveradio.de and other public-facing media. Richard was an intensely private man who had no close family, but he reached thousands of friends daily through his website. Amateur radio has lost a true communicator.

Next weekend, the 144MHz CW Marconi Contest runs for 24 hours from 1400UTC on Saturday. Using CW only, the exchange is signal report, serial number and locator.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 28th of October 2022

Good conditions on HF have continued with only a short geomagnetic disturbance to dull things a little. The planetary Kp index got up to five on the 25th, due to plasma from a geo-effective coronal hole, but luckily it recovered quite quickly. Two days later it was back to one and the upper HF bands came alive again.

The ionosphere was disturbed on the 23rd and 24th, with the MUF over a 3,000km path dipping in and out of the 10m band. But by the 25th things were pretty much back to normal.

The solar flux index dropped down to 105 on the 22nd but recovered a little to end at 122 on Thursday.

It has once again been a good week for 10m with openings to the US being commonplace. This is a good opportunity to up your Worked All States score with the 14, 18 and 21MHz bands remaining open long after sunset. 28MHz is also shining during daylight hours.

Other notable contacts were AH7C Hawaii on 10m FT8 long path by Darren, G0TSM. Darren also worked P29RO, the German DXpedition to Papua New Guinea, on all bands from 18 to 28MHz.

Next week NOAA predicts that the solar flux index will remain in the 100-118 range. Unfortunately, the Kp index is expected to rise to five on Saturday the 29th due to an enhanced solar wind stream from a trio of coronal holes on the Sun’s equator. This may no doubt impact conditions for the CQ Worldwide Phone Contest this weekend.

NOAA thinks the unsettled conditions could linger until Thursday, November the 3rd when the Kp index may return to two.

And finally, please note that the data feed from the Chilton Digisonde has not been reliable this week. To circumvent this, on Propquest.co.uk we recommend selecting FF051 Fairford to maintain the graphs.

And now the VHF and up propagation news

The autumnal weather remains in control and the basic pattern changes very little over the coming week.

This places low pressure to the southwest of the British Isles and a mild south-westerly wind bringing periods of rain as fronts cross the country with intervening spells of showery weather in between.

The result of all this for VHF and UHF propagation is that rain scatter continues to have a look-in on the GHz bands. But this is very little comfort for tropo operators since high pressure does not really feature at all in the coming week, other than occasional weak transient events alongside weather fronts.

The ever-present chances of aurora are always a possibility, so keep up to date with VHF cluster reports of current activity levels to ensure you don’t miss out on any openings.

The Propquest.co.uk graphs have shown isolated occasions with Sporadic-E recorded on the foEs plots, so always worth a check on 10m and 6m for strong short skip European signals, especially on digital modes.

Random meteor scatter in the hours around dawn is always a banker for propagation and we are still in the tail end of the Orionid and Leonis Minoris showers to add to the mix. Next Sunday, the 6th, marks the onset of the big Leonids shower, peaking around the 16th.

With the Moon at minimum declination this weekend, Moon windows will be short but lengthening as the week progresses. Perigee was yesterday, Saturday, so path losses are at their lowest. 144MHz sky noise is low in the coming week.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 21st of October 2022

We had another great week of HF propagation, helped no doubt by a very low geomagnetic Kp index meaning the ionosphere remained settled.

Despite the solar flux index declining to 113 by Thursday, 10m has been highly active with openings every day. We have had good daily 10m openings, even out as far as the west coast of the USA for well-equipped stations.

Next week NOAA predicts that the solar flux index will continue to remain in the 110-120 range. This is not extreme but would be enough for good propagation on all of the upper HF bands if we don’t have any geomagnetic disturbances.

A rather large coronal hole is rotating into view and should become Earth-facing on the 21st. This is fairly low on the Sun’s face so might not impact us as badly as a coronal hole on the solar equator would. But, nevertheless, its size suggests that any disturbance might be long-lived. If so, expect its plasma to hit Earth late Saturday or Sunday.

NOAA also predicts that the Kp index will rise on Wednesday the 26th of October with the index rising to five. Quite what will cause this is unclear, although it could be the return of an active region that took the Kp index to six 27 days ago.

Once that clears, we may expect good conditions on 10m to hopefully continue, so make the most of them.

And now the VHF and up propagation news

The current transition to changeable autumnal conditions is fully complete and proving very difficult to shift. This means that the breezy unsettled weather with low-pressure systems pushing fronts across the country will continue during the period.

This may produce some rain scatter options, although it's not a big 'shout-out' compared to the intense thunderstorms of high summer.

There will be some high pressure nearby over the continent, but it’s not likely to be a big Tropo player and remains largely out of reach from the UK.

One minor meteor shower, the Leonis Minorids peaks on Tuesday the 24th of October, but the ZHR is low.

Aurora could crop up on occasion during the coming week and, after recent activity levels on 6m, there is still a chance of Sporadic-E. This recent activity just shows that we should probably learn to regard it as an option, especially on FT8, even in the nominal ‘close season’ for Es.

Moon declination goes negative today, Sunday, so Moon windows continue to shorten as the week progresses. With perigee next Saturday, path losses will fall throughout the week. 144MHz sky noise starts low, but there is a partial solar eclipse on Tuesday the 25th so that day will be an EME washout. After the eclipse, the noise rises slowly from 380K to around 3000K next Saturday, making it a noisy week for EME.

And that’s all from the propagation team this week.

The news headlines:

• IARU President Keynote Speech at the 2022 RSGB Convention
• Celebrating 100 Years of the BBC
• New Transponder Bandplan for QO-100

Last weekend the RSGB held its first hybrid Convention which had speakers, attendees and live stream watchers from across the world. The keynote presentation by IARU President Tim Ellam, VE6SH, who also holds the callsign G4HUA, was very thought-provoking. In it, he highlighted the threats to amateur radio as well as the importance of embracing modern techniques, whilst also being willing to adapt and change. The Society has released a standalone recording of Tim’s presentation on its YouTube channel, combined with his interesting Convention Chat with the RSGB and IRTS Presidents. The RSGB would like to thank everyone who gave a presentation, as well as those who attended the Convention, whether in person or online. It is also grateful to the RSGB General Manager and Convention Chair Steve Thomas, M1ACB and his hard-working Convention team who made this such a fantastic event. Individual presentations will be released over the coming months, first on the RSGB website for its members and then on YouTube for everyone to see. The two live streams have already had thousands of views – to see either of those or to watch Tim’s keynote speech, go to youtube.com/theRSGB

On the 18th of October 1922, the Marconi Company and other equipment manufacturers formed the British Broadcasting Company, which became the British Broadcasting Corporation six years later. To mark this momentous date exactly 100 years on, members of the BBC Amateur Radio Group have been invited by Arqiva to operate for the day at the Daventry transmitting station that was home to so much of BBC short-wave broadcasting over the years. Members of the BBC and Arqiva clubs will be operating HF on Tuesday the 18th of October from the Empire Service Building at the Daventry site. As well as GB100BBC, the callsign G2LO will be on air. 2LO was the callsign allocated to the very first BBC transmitter, built by Marconi and located at Savoy Hill in London. Keep an eye on the GB100BBC QRZ page for more information.

At the 2022 AMSAT-UK Colloquium on Saturday 8th October, a new narrowband transponder bandplan for the QO-100 geostationary amateur satellite was announced. Among other changes, AMSAT has allocated a new ‘broadcast’ spot frequency which is intended for the news services of amateur radio organisations. The RSGB’s news service GB2RS has been transmitted via QO-100 for some time and has already clocked up 70 broadcasts. It is very popular, with an audience within the footprint of the satellite which covers almost half of the world’s surface. Following this announcement, GB2RS will be moving to the new broadcast frequency of 10489.855MHz with immediate effect. The transmission is at 0800UTC every Sunday. Perhaps in the future, the news services of other amateur radio organisations will follow the RSGB’s lead and make use of this special allocation to reach a diverse international audience.

Jamboree On The Air is an annual event in which Scouts and Guides all over the world communicate with each other via amateur radio. JOTA 2022 ends its 48-hour run at 2359UTC today, the 16th. You can find out more at jotajoti.info

The Royal Air Force Air Cadets will be running the popular Blue Ham Exercise on the 22nd and 23rd of October from 0800 to 1800UTC each day.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 14th of October 2022

We had yet another week of good HF propagation, helped by reasonably settled geomagnetic conditions.

Although the week started relatively poorly with a Kp index of four all day on Sunday, that soon improved slightly and the rest of the week saw the Kp index hit only ones or twos.

The solar flux index declined from 161 on Sunday to 141 on Thursday, which is still more than enough for 10m openings at this time of year.

Solar activity was low. Active region 3112 underwent decay but managed several C-class flares. Region 3119 was stable and also produced a few C-class solar flares. The other regions were unremarkable. No Earth-directed CMEs were observed in coronagraph imagery.

Low solar activity is expected to continue, with a chance for M-class flares on 13-15 October.

At the RSGB Convention in Milton Keynes, the special event station just outside the conference centre was able to work a string of US stations on 10m just to prove that this really is the month for Autumn DX.

The KQ2H repeater in the Catskill Mountains of upstate New York on 29.620MHz has also given many people their first taste of FM on 10m, along with characteristic phase distortion.

Other DX worked this week by well-equipped stations on 10m include FK4QX in New Caledonia and TX7G on the Marquesas Islands. Hopefully, if conditions remain like this, it will make the CQ Worldwide SSB contest on the 29th and 30th of October very interesting.

Next week NOAA predicts that the solar flux index may remain in the high 130s. After predicting slightly unsettled geomagnetic conditions on Saturday, NOAA says the Kp index should then fall from four to two until Wednesday the 19th. The latter half of the week may become reasonably unsettled again with a Kp index of four. The US Air Force, however, predicts that this weekend should remain settled geomagnetically – we shall have to wait and see.

And now the VHF and up propagation news

The current spell of unsettled weather will continue through much of the coming week. There may be a hint of a temporary high over the north and east of Britain around midweek, but this is unlikely to benefit western areas.

Any Tropo wins will probably be across the North Sea to Scandinavia and the Baltic region, but only from the easternmost counties of England and Scotland. The low-pressure systems which will dominate are likely to bring spells of heavy rain and passing showers at times. There may be some rain scatter possibilities from this unsettled weather, especially from heavy coastal showers.

The aurora propagation mode is always worth considering around the autumn months, so monitor the Kp index, and meteor scatter, particularly in the hours before dawn. The Orionids meteor shower peaks on Friday the 21st with a medium ZHR of 20 so look out for improved conditions around that date.

The Moon is at maximum declination today, Sunday, so Moon windows are at their longest, shortening as the week progresses. With apogee this coming Monday, path losses are at their highest. 144MHz sky noise is low all week.

Finally, a word about Sporadic-E, of which you may still hear examples on the HF bands as extra-loud short-skip from Europe.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 7th of October 2022

Yet another good week for HF propagation has passed, although it has been borderline in terms of geomagnetic disturbances.

The Kp index hovered around the four mark all week, mainly due to high-speed streams from the solar wind, possibly from slight glancing blows from incoming CME material. There have been a few M-class solar flares, but nothing too violent. The risk of X-class flares though remains relatively high.

The solar flux continued to climb despite pessimistic predictions, ending up at 161 and a sunspot number of 151 on Thursday.

Daytime critical frequencies have been in the range of 7.5 - 8MHz, meaning 40m has been an excellent inter-G band during the day. MUFs over a 3,000km path have been exceeding 24.9MHz, and occasionally 28MHz, especially in the early afternoon.

This has meant that HF propagation has been good with excellent openings on all the upper HF bands. Paul, GM4ULS has even reported hearing what we believe to be round-the-world echoes while listening to high-power European stations on 20m calling for long-path Asia, VK and ZL contacts in the morning.

This is a sure sign that the ionosphere is playing ball!

Next week the US Air Force predicts that the solar flux will remain in the 150s to start with, but may then decline into the 130s as the week progresses. The Kp index is predicted to be no more than three all week, although an incoming CME could soon spoil that.

Coronal hole activity appears to be minimal, once we get past the effects of a small hole on the equator, which became Earth-facing on Wednesday. This could result in the Kp index rising on Friday, although the hole’s size means the effects may be short-lived and perhaps minimal.

So in conclusion, it is Autumn with an SFI in the 150s and an active, but not unsettled, geomagnetic field. In other words, it should be good for HF DX unless a solar flare or CME comes along and spoils things.

And now the VHF and up propagation news.

The typical Autumn weather will continue over the next week, meaning alternating ridges of high pressure between active weather fronts with rain and strong winds.

There have been some reasonably uplifted Tropo conditions during recent spells of high pressure and no reason to think this won’t be the case over the next week. The two most likely high-pressure transitions across the country are this weekend and again in the first half of next week. Paths to the south into the continent should do well.

In between these events, we find active weather fronts crossing the country with a large low taking up residence by the end of the week. This could lead to a few rain scatter options for GHz bands, but Autumn storms can be fast-moving and hard to track.

The Sun continues to offer support with a high Kp index on occasion so always a chance of aurora.

The Draconids and the Orionids are the major meteor showers this month. The former, peaking today, Sunday, with a typical ZHR of 10, has been known to reach storm level. The Orionids are active from the 2nd of October to the 7th of November peaking on the 21st with a medium ZHR of 20.

Random meteor scatter propagation is always available and rates are high in October, so it’s always a banker if you have a decent system for the low VHF bands.

With all these more exotic modes the best course of action is to monitor the clusters for signs of activity.

Moon declination goes positive today (Sunday), so Moon windows will lengthen as the week progresses. We are past perigee so path losses will increase throughout the week. 144MHz sky noise is low all week.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 30th of September 2022

The HF bands have been really humming this week, making up for the summer doldrums. A lot of this is due to the seasonal change in the ionosphere that results in more monatomic species and fewer diatomic ones.

These are easier to ionise, which is good news for radio amateurs everywhere as the MUF rises.

A quick check shows that all the HF bands up to 10m have been serving up DX, so make the most of it. There have been 10m openings as far as Wyoming and California. The solar flux index has been static at 135, and that may not change too much as we enter next week with the return of old sunspot region 3098, which still appears to be active.

The Kp index reached six on Tuesday due to the impact of a coronal mass ejection on the Sun. This resulted in widespread visible aurora.

Unfortunately, a large coronal hole will become Earth-centric on Friday the 30th, which may result in a high-speed solar wind stream that is expected to reach Earth beginning late on the 30th of September and into the 1st of October.

If the stream’s Bz is pointing south it could result in minor (G1) to moderate (G2) geomagnetic storming. Visible and radio aurora at higher latitudes may be possible heading into the new month as well.

NOAA predicts that the solar flux will remain around the 130 mark, but that the Kp index may elevate to five or even six over the first half of the week.

So we may have seen the best of the DX for the time being, at least until the Kp index recovers.

And now the VHF and up propagation news.

The current period of weather is fairly typical of autumn with a mix of fine, settled ridges of high pressure interrupted by some passages of low pressure with their attendant fronts and bands of showers.

These can be very vigorous systems with scope to bring gales to some areas making this a good time of the year to make those final checks of antenna guys and fixings before winter comes.

In terms of propagation, there will be some active rain bands crossing the country, plus a chance of a few showers. This raises the possibility of some rain scatter on the GHz bands, although less intense than summer events.

The shower part of the story tends to favour the seas around our coasts, but in stronger autumn winds you will need to keep on top of the tracking rate which can be quite brisk.

The occasional periods of high pressure bring a good chance of Tropo at times, especially towards the continent from Biscay and France across to Germany and Poland. There will be some overnight mist and fog, which usually gives a boost to Tropo for part of the day at least.

Other exotic modes, like aurora, are certainly worth consideration after recent examples, plus of course, the chance of some random meteor scatter.

The daytime Sextantid meteor shower is still active through to the 9th of October although we are past the peak.

The Moon is at minimum declination today (Sunday) and at perigee on Tuesday. Path losses will be low and Moon windows will lengthen as the week progresses. 144MHz sky noise is high today, but low from Tuesday.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4DDK on Friday 23rd September 2022.

Last week saw the solar flux index decline very slightly to 137. The good news is that we have had reasonably-settled geomagnetic conditions. The highest Kp index has been three, but it has often been at zero or one. This is good news as it means that the ionosphere has had a chance to develop.

The MUF over a 3,000km path has often exceeded 28MHz, especially in the early afternoons. This will probably improve further as we head into late September and early October.

The result is that some good DX has been available. J20EE in Djibouti, Africa has been workable on 10m CW, as has ZD7BG on St Helena. And ZL7/K5WE on Chatham Island is reported to have been “very easy” to work on 40m. The 4X6TU IBP beacon in Givatayim, Israel on 28.200MHz has been audible down to one watt recently, which is very encouraging. Numerous North American low-power beacons have also been audible, including the five-watt K5TLL on 28.298MHz in Hattiesburg, Mississippi.

As we head into next week, the Sun will be dominated by active regions 3105 and 3107. Region 3015 is actually the remains of AR 3089. A cluster of sunspots in 3105 continue to turn into view off the southeast limb and for now, they remain mostly stable, however minor solar flares will be quite possible.

NOAA predicts that the solar flux index may decline to the mid-120s next week. Geomagnetic conditions are predicted to remain calm, at least until the 29th when the Kp index is predicted to rise to five or even six. A single CME could soon disrupt the calm so don’t expect the good conditions to last.

And now the VHF and up propagation news.

The weather has a noticeable autumn flavour to it lately and the coming week is continuing that theme.

As this was being prepared on Wednesday evening, there is a hint of tropo over the southern half of the British Isles, but as soon as a cold front completes its journey south on Thursday, we enter a period of cooler north-westerly winds. This will bring rain and showers and means that for most of this weekend and next week, rain scatter is a good option for the GHz bands.

Late in the week, and probably nearer next weekend, we find another high edging closer to Ireland and western Britain, perhaps bringing some patchy Tropo down the western side of the country.

A further possibility is for meteor scatter and auroral propagation to present themselves as an option, but see the HF section earlier for the solar details and implications. The Kp index rising above five will be a useful guide for the chance of aurora.

There are no major meteor showers in the coming week, although towards the end there may be some early Orionids shower reflections. This shower will peak between the 2nd and 7th of October.

It is also worth watching for reflections during the daytime from the Sextantid meteor shower, which is active until the 9th of October. The peak is expected to be around the 27th of September. Good hunting!

The Moon will be low in the sky throughout this week and as this coincides with the Moon getting closest to the Earth, path losses will be the lowest.

With the equinox now past, the Sun will not appear above the Ecliptic again for another six months. This will make Sun-to-cold-sky noise measurements less easy. If you need to make these measurements, and there are a few EME operators who don’t, now is probably a good time to do them before those horizon trees get in the way!

And that’s all from the propagation team this week.

The news headlines:

• RSGB HQ and the National Radio Centre closed on Monday
• Special Regional Secondary Locator
• RSGB Convention latest

Our thoughts are very much with the Royal Family as they mourn the death of Her Majesty Queen Elizabeth II. The RSGB will be closing its HQ and the RSGB National Radio Centre on Monday the 19th of September, the day of the Queen’s state funeral, as a mark of respect.

In response to requests from radio amateurs and after contact from Ofcom, the RSGB will be making available the special Regional Secondary Locator of Q. Any licensed radio amateur may choose to use this after their UK callsign prefix to show their respect for the Queen if they wish to do so. For example, GQ4LFM, MQ1ACB or 2Q0ABC. It will be available until the end of official national mourning on Monday the 19th of September. Radio amateurs will need to download the Notice of Variation that is available from the RSGB website at rsgb.org/nov. You may be interested to note that Australian amateurs may use the AX prefix between the 19th and the 23rd of September to commemorate the life of Queen Elizabeth II.

The RSGB Convention will take place from the 7th to the 9th of October. The online booking system for overnight packages, dinners and day tickets will close on the 2nd of October. The latest information can be found at rsgb.org/convention Don’t forget that all three UK amateur radio exams may be taken online at this year’s RSGB Convention. The Foundation and Intermediate exam will take place on Saturday and the Full exam on Sunday morning. You will need to book a place via the online form before the 26th of September. Applications will not be accepted on the day. If you have a question, please email exams@rsgb.org.uk or you can book your place via the link on the RSGB’s Convention web page at rsgb.org/convention.

The RSGB is bringing its Jubilee activities to a close as a mark of respect for the Queen. The Society’s website is being updated and the Innovation 70 award has been cancelled. If you have collected QSOs between the 1st and the 30th of June for the Jubilee Award 70, you may still submit an application to the RSGB Awards Manager before the 31st of October. Details of how to do so will remain on the awards section of the RSGB website at rsgb.org/jubilee.

As the World Radiocommunication Conference 23 approaches, the studies regarding 23cm and RNSS satellites are working towards conclusions. However, the IARU is not content that all the operational aspects of the amateur service usage of the 1240 to 1300MHz band are being properly considered to develop an acceptable compromise for all concerned parties. You can find some more detail on the areas of concern in the discussion paper posted on the global IARU WRC-23 web pages at iaru-r1.org.

On Friday the 23rd of September, a team from hi-impact, based on the Wirral, will be working with Everton Free School on another High Altitude Balloon launch. Launching near Welshpool, at 11 am, you can listen out on 434.250MHz USB and the RTTY transmission will be 300 baud with a 910Hz shift. The callsign will be EVERTONFS. The flight will be SSDV enabled, so there will be pictures being beamed back to earth.

The Radio Amateurs of Canada, the national society in Canada, is holding its AGM today at 1600UTC. The AGM will start with A Fireside Chat on the Future of Amateur Radio. Those involved will be Tim Ellam, VE6SH, President of the IARU, Rick Roderick, K5UR, President of the ARRL, Stewart Bryant, G3YSX, the RSGB President and Phil A. McBride, VA3QR, the President of RAC.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday 16th September 2022.

We had an expected boost to the solar flux index last week, thanks to a returning sunspot group. This, when added to sunspot region 3098, pushed the SFI to 152 on the 11th. The returning group, which has now been updated to active region 3102, isn’t quite the threat it was on its last visit, but may still be capable of M-class solar flares.

The good news is that an SFI of up to 150+, coupled with better Autumnal propagation, has seen the HF bands come alive at times.

Jeff, ZL7/K5WE on Chatham Island has been workable on 40m CW and FT8. He is due to be on air until the 21st of September. Brian, 9J2BO in Zambia, a regular in the Commonwealth Contest, has also been worked on 10 metres CW. It is worth noting that this is a good month for north-south paths, such as the UK to South Africa, and the UK to South America.

The beginning of last week was better than the second half, which suffered from an elevated Kp index due to an enhanced solar wind. Also, a high-speed stream from a high-latitude coronal hole on the Sun was forecast to batter the Earth from the 16th onwards.

The critical frequency over the UK has fluctuated from less than 5MHz at sunrise to more than 7MHz around lunchtime and later. If you are looking for good inter-G conditions you are better off waiting until the afternoon.

Next week, NOAA predicts that the SFI will decline into the 120s. This weekend may also be unsettled on the geomagnetic front as well. Expect the Kp index to rise to four or five, with a characteristic drop in the MUF. Hopefully, conditions will improve after the weekend with the Kp index forecast to drop to around two.

As always, things can change very quickly, thanks to solar flares and CMEs, so keep an eye on solarham.com and propquest.co.uk

And now the VHF and up propagation news.

There should be some useful Tropo about in the coming week, initially over western Britain at first, but gradually extending across most areas as high pressure moves in across the British Isles.

The eastern side of the country will start this weekend in a more showery northerly flow down the east coast, so Tropo is unlikely here until we are into next week. Once established it should bring enhanced conditions to most areas and into the near continent, but limited options across the North Sea where the cool showery weather retains control and limits the potential for QSOs to the east.

The other modes to have in mind are meteor scatter, particularly in the early mornings. The Sextantids meteor shower is underway but doesn’t reach its peak until the 27th.

In the disturbed sequence of solar conditions, an aurora is always a possibility so keep an eye on the Kp index; anything above five should be worth checking out.

The Moon is at maximum positive declination at the moment, so is visible for long periods. Apogee is the point at which the Moon is furthest from Earth. It takes place on Monday when path losses are at their highest for the month. 144MHz sky noise starts the week at a moderate 500 Kelvin but quickly falls low for the rest of the week.

And that’s all from the propagation team this week.

• The death of Queen Elizabeth II
• Bletchley Park and NRC open
• EMF lecture and workshop at the RSGB Convention

We are deeply saddened by the death of Queen Elizabeth II. Our thoughts are with the King and all members of the Royal Family at this sad time.

Bletchley Park Museum, and hence the National Radio Centre, will remain open in the coming days but will be closed for the day of the funeral. More information will follow once the date of the funeral has been announced.

There will be EMF Compliance events at the RSGB Convention on the 8th and 9th of October. On the morning of Saturday the 8th, John Rogers, M0JAV of the RSGB, ARRL and IRTS EMF team will give an update on EMF compliance developments. This will include the updated RSGB EMF Compliance App and the results of some measurements made. Then, on Sunday morning, team members Peter Zollman, G4DSE and Ian White, GM3SEK will run an open Compliance Clinic. If you have already carried out an EMF compliance assessment but are not sure how the results relate to your situation, they will work through some site-specific cases to put the principles into practice. Please check the Convention timetable for final details. You can email your questions in advance to emc.chairman@rsgb.org.uk.

The July edition of the IARU Monitoring Service Region 1 Newsletter is now available. In this issue, you can read more about how ‘Over the Horizon’ radars were the most obvious transmissions causing harm to our amateur radio HF bands. The front runner was the Russian ‘Contayner’ with a bandwidth of 12kHz at 40 symbols per second, received in all bands from 40 to 12m. The others sending short bursts with bandwidths of 10kHz at 50 symbols per second, were also very active and were mostly observed on the 20m and 15m bands. To read the full report go to iaru-r1.org. Word has just arrived via the South African Radio League that three new African countries have joined the ranks of 5MHz or 60m operators. They are Botswana, Lesotho & eSwatini, formerly known as Swaziland. Each has the new WRC-15 Amateur Secondary Allocation of 5351.5 to 5366.5kHz. This makes a total of 89 countries now on the band worldwide. Thanks to ZS4BS and SARL for the information.

All three UK amateur radio exams may be taken online at this year’s RSGB Convention. The Foundation and Intermediate exam will take place on Saturday and the Full exam on Sunday morning.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday 9th September 2022.

What a week we have just had! The Kp index stayed at four or more for most of the week thanks to an enhanced solar wind stream. This continued to stir up geomagnetic activity with minor, G1, storm conditions.

Visible aurora has been reported at higher latitudes.

Sunspot region 3089 has now rotated behind the Sun’s west limb, which may help with conditions as it was responsible for an M-class solar flare on the fifth.

A significant space weather event took place during the week, but luckily it was on the far side of the Sun. A large, full halo coronal mass ejection, CME, became visible on imagery courtesy of both the LASCO and STEREO Ahead spacecraft. This was possibly connected with active region 3088, which will rotate back into view next week so perhaps look out for more disturbed conditions.

News of sunspots has become almost secondary to the geomagnetic reports, but at the time of writing, there were five active regions facing the Earth and a solar flux index of 126. This has remained roughly static all week.

Despite the disturbed conditions, ionospheric propagation has remained good at times, with MUFs over 3,000km exceeding 21MHz according to Propquest.co.uk. This may be mainly due to a seasonal change in the ionosphere, which may see MUFs rising as we go further into Autumn. Meanwhile, fourteen megahertz may remain more reliable for DX, while the higher bands may provide more fleeting openings.

A quick tip - the feed from the Chilton Digisonde on Propquest has not been terribly reliable recently so we recommend switching to Fairford data and refreshing the display for the best results.

Next week NOAA predicts that the solar flux may remain in the mid-120s. Geomagnetic conditions are due to be unsettled again and we may see the Kp index rise to four, especially around the 13th-15th. Otherwise, expect it to be around two to three.

And now the VHF and up propagation news.

The large slow low pressure that brought numerous heavy showers and thunderstorms to dent the drought has started to drift away to the east and will allow one more low and area of rain to affect the country at the end of this weekend and early this coming week.

There is still an opportunity for some good rain scatter on the GHz bands, but eventually, it seems that high pressure may try to return around the middle of the week. Not a very strong signal and the models suggest that low pressure is back again by the end of the week, meaning not an especially good, and probably short-lasting, Tropo event.

So, rain scatter on the GHz bands is the primary mode, followed by a hint of Tropo midweek and then don’t forget about meteor scatter and aurora as occasional "long-shots".

The Epsilon-Perseids meteor shower is still active and the Sextantids shower gets underway this week.

The geomagnetic field has been very disturbed lately and there have been some good aurora openings recently, so you've probably already been keeping an eye on the Kp index; anything above five should be worth checking out.

With the Moon at positive declination from today, and past last Wednesday’s perigee, expect low but increasing path losses and lengthening Moon windows. 144MHz sky noise is low all week, not exceeding 500 Kelvin until next Saturday night.

And that’s all from the propagation team this week.

GB2RS News

Sunday the 4th of September 2022

The news headlines:

• Syllabus 1.5 checks finished
• Tonight @8 restarts for a new season
• Regional hub for makers to meet

The Examinations and Syllabus Review Group has just completed an editing and checking exercise for all the v1.5 syllabus content on the RSGB website. The single-tier and three-tier versions should have exactly the same content and, by majority request, Oxford commas have been removed. The old syllabuses can still be found on the RSGB website, while the new syllabuses can be found at rsgb.org/syllabus2019. The Group has also been working on the sample examination papers and sample questions on the RSGB website in order to bring them into line with version 1.5. As the majority of candidates will now be taking examinations online, as opposed to paper-based exams, the front sheets of the sample papers have been adapted to reflect this transition. The sample questions are now shown using an Excel spreadsheet rather than a pdf. The updated sample examination papers can be found at rsgb.org/mock-exams.

The first Tonight@8 talk of the new season will be on Monday the 5th of September. Mike Richards, G4WNC will talk about going Back to the keyboard! He says that now we have filled our logbooks with FT-8 contacts, maybe it’s time to move on and start communicating again. In an illustrated talk, he will introduce you to the best data modes for keyboard QSOs with a special focus on VarAC. In addition to explaining their operation, Mike will run through some operating techniques to take the strain out of keyboard QSOs. It will be streamed live on the RSGB’s YouTube channel and via the BATC allowing you to watch the presentation and ask questions online. To watch the Tonight @8 talk, go to youtu.be/SC0UxNG2itE.

A regional hub for makers and home brewers of radio-related projects is proposed by Eric, M0REQ and Graham, G4NMD. The idea is for a club that co-operates with knowledge, experience and test gear to support those who are already building or wishing to build radio-related projects. The inaugural meeting is set for Wednesday the 7th of September at 7.30 pm at Grafham Rooms, Grafham, Surrey GU5 0LJ. More details by e-mail to HamRadioBuilders@gmail.com.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 2nd of September 2022.

Many amateurs thought Christmas had arrived early when a solar flux index of 252 was posted on the 28th of August. This would have been representative of a very good solar maximum. Unfortunately, it wasn’t to be as the previous day’s SFI had been 128 and the following day it was 131.

Solarham.com reported that the figure had been ‘contaminated’ by solar flaring just before the measurement was taken and the lack of excellent DX reports on the higher bands seems to support this. Sorry if you got your hopes up, but meanwhile it is back to sunspot normality, at least for a few years yet!

If we exclude the anomaly, the solar flux varied from a low of 113 on the 31st to a high of 131 on the 29th. Region 3089 has probably contributed most to this but will be rotating out of view this weekend. It does look as though there are some active regions lurking just over the Sun’s eastern limb, which could push the SFI up over the next week.

There were multiple R1/R2 radio blackouts on Monday the 29th due to M-class solar flares. Unfortunately, a large coronal hole on the Sun’s equator will become Earth-facing on Friday, which could result in the Kp index rising as the plasma hits the Earth, perhaps late on Sunday. This could bring a short-lived ionospheric enhancement, followed by a decline in the MUF as any geomagnetic storm progresses.

Next week NOAA predicts that the solar flux index will be in the range 108-124, so expect similar conditions to last. This may be better later in the week once the geomagnetic conditions settle.

As we head into Autumn, we can expect a general improvement in HF conditions and hopefully the return of trans-Atlantic DX on the higher bands.

And now the VHF and up propagation news.

The weather this week could become very unsettled. Most models agree on the overall trend towards wetter weather, but the details are going to prove difficult except on a day-by-day basis.

The reason is that the mechanism of change brings a large slow-moving low over the country at the weekend where it remains for much of next week. For many areas, particularly the east, the rain will be in the form of showers, some heavy, thundery and localised rather than widespread.

For propagation, this means that rain scatter is a good mode to look at for the GHz bands and the various online radars will tell you where the big storms are, and their movement.

It does suggest that VHF/UHF Tropo will not be a big player, which presents challenges for those on the 144MHz contests this weekend and the UKAC next week. It is possible that we may find a return of high pressure and perhaps some Tropo from the northwest during the following weekend.

The Sporadic-E season has all but faded away, but keep a watch on 50MHz especially as we approach the UK Activity Contest on Thursday evening since Es have been known to crop up in the first week of September.

Despite there being no big meteor showers in September, random meteor rates are at their maximum, providing relatively good propagation, especially around dawn. That said, the Aurigids shower reached its peak last week, and the Epsilon-Perseids peaks this coming Friday night. This shower has a history of surprising outbursts.

The Moon is at minimum declination today and at perigee on Wednesday, so expect the lowest path losses, but short Moon windows. 144 MHz sky noise is high until Tuesday but low after that.

And that’s all from the propagation team this week.

Sunday the 28th of August 2022

The news headlines:

• Get ready for the Transatlantic tests
• National Radio Centre contacts the ISS
• GB3HA is back on air in Northumberland

The RSGB is hosting The Transatlantic Centenary Tests on the HF bands, for the entire month of December 2022. This is to commemorate the centenary of the achievement of amateur transatlantic communication, during the tests that were held between 1921 and 1923. Unlike the tests of the 1920s, which consisted of one-way communication, the 2022 tests will encourage worldwide two-way communication with UK & Crown Dependency-based stations. For those activating special stations, there will be a series of awards available. With the assistance of Ofcom, the RSGB has reactivated five callsigns that it held in the 1920s. These historic callsigns will be activated by RSGB Members and clubs. You can read more about the original transatlantic tests and how to participate in 2022 at rsgb.org/transatlantic-tests.

RSGB National Radio Centre volunteer Steve, 2E0YBJ, was able to show the visiting public a live radio contact with the International Space Station using GB3RS. He was using the demonstration station at the NRC, running SatPC32. This is used to track Earth Low Orbit satellites and, more recently, the onboard ISS repeater. Steve put his success down to two factors; the excellent NRC station set-up and the fact that the ISS approaches the UK from the West. This enables UK stations to ‘see’ the ISS before its communications footprint passes over mainland Europe. It was an unexpected treat for the Bletchley Park visitors, a super result for Steve and a first for GB3RS.

The Northumberland 2m repeater, GB3HA, is operational again serving the northeast of England. To celebrate the switch on, a short check-in net will be held on Tuesday the 30th of August at 7.30 pm. Net control will be Roy, M0TKF, and all radio amateurs within the repeater coverage are welcome to call in for a quick hello. Please check the GB3HA page on QRZ.com for frequencies and access information.

NASA is well known for communicating with astronauts on space missions, but radio amateurs may also contact NASA centres around the world. Until the end of this year, NASA will mark several past and present-day key milestones. NASA Amateur Radio Clubs at the agency’s centres and support facilities across the United States plan to participate with ‘NASA on the air’ special event stations. Look out for events to celebrate the Artemis launch over the next few days. The 22nd of September is National Astronomy Day and special event stations will be on the air for that too. To learn more about NASA on the Air events, go to nasaontheair.wordpress.com.

The cross-band voice repeater and the APRS node aboard the International Space Station can now be used simultaneously. The FM repeater uplink is on 145.990MHz and a 67Hz PL tone is needed to activate the downlink transmitter on 437.800MHz. APRS and packet mode uses 145.825MHz for uplink and downlink. The Columbus module radio uses the callsign NA1SS and the new service module radio uses the callsign RS0ISS. Both radios are expected to be operational at all times, except during school contacts, spacewalks and docking manoeuvres. The operational state of the ISS ham-radio station can be found on the ARISS website at ariss.org.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 26th of August 2022.

There was a welcome upturn in ionospheric propagation this week, with much DX being worked. While the solar flux index remained mainly in the low 100s, quieter geomagnetic conditions, with the Kp index at one or two, helped a lot. We are also heading towards September and better propagation conditions as the ionosphere cools down, resulting in more monatomic elements and fewer diatomic ones. The monoatomic elements in the ionosphere are easier to ionise so MUFs go up accordingly.

Along with daytime critical frequencies above 6MHz, we have seen 40m opening up to shorter distances too, sometimes down to 100km, but mainly in the range 100-500km.

Over longer distances, there have been reports of some choice DX being workable, including KH6KB in Hawaii on 17m CW, 9V1YC in Singapore on 12m FT8 and A35JP in Tonga on 15m FT8.

As long as the Kp index stays low we can expect a lot more like this over the coming months.

Next week, NOAA predicts that the solar flux index may climb a little, perhaps ending the week in the range of 110-116. Geomagnetic conditions are unlikely to be as good next week, with the 27th of August being the most disturbed with a predicted Kp index of four.

A large coronal hole is moving to be Earth-centric on Friday, although it is largely at one of the Sun’s poles. This means that any fast solar wind might be directed away from Earth, but we could get a glancing blow late on Sunday or early Monday.

Watch for a rise in the Kp index and a general lowering of the MUF if it does.

And now the VHF and up propagation news.

The end of last week finally brought some heavy rain and thunderstorms to some eastern areas and weakening weather fronts to the northwest. This may have given some rain scatter opportunities, but only temporarily.

As we head through this weekend high pressure starts to rebuild over the UK and will dominate the weather over the British Isles over the coming week. This will make Tropo a principal player for the next week. In early September it's still plenty warm enough that inland areas could see the temperature inversions breaking down during the daytime heating, so for best results make the most of the nighttime and early morning lifts.

We may have a few days left when Sporadic-E could occur before the transition away from high summer weather patterns, but it is getting much harder to find now. Focus on 10m or perhaps 6m digital modes for best results and, of course, check the usual DX clusters.

Don’t forget aurora and meteor scatter modes, however this week, these modes will be overshadowed by the Tropo characteristics as the high builds.

Moon declination goes negative again late Monday, so shortening Moon windows this week. Path losses continue to fall throughout the week and 144MHz sky noise is low until next weekend.

And that’s all from the propagation team this week.

The news headlines:

• Sponsoring young contesters
• 8-year-old speaks to the ISS
• British Inland Waterways on the Air

The CDXC and the RSGB are pleased to announce their joint sponsorship of one of the Youth Teams at the World Radiosport Team Championship. The Championship is due to take place in Bologna, Italy in July 2023. In order to promote contest activity by young radio amateurs, the organising committee reserved six sites for young contesters. Jamie Williams, M0SDV and Philipp Springer, DK6SP will form Youth Team 2 and will be the team jointly sponsored by CDXC and RSGB.

On Tuesday, the 16th of August, BBC TV spoke to 8-year-old Isabella about her contact with a NASA astronaut on the International Space Station. On the 2nd, Isabella used her dad's callsign M0LMK to make supervised contact with the ISS amateur station. Isabella, a member of the Hilderstone Radio Society, has been involved in several amateur radio events and is working towards her own amateur radio licence. BBC South East Today for the 16th of August is available on the iPlayer and this interview is about 15 minutes into the show.

British Inland Waterways on the Air takes place between the 27th and 29th of August. It is open to all amateurs who are boaters, cyclists, walkers and other users of the canals, rivers, towpaths and riverbanks for work or recreation. Even lakes and reservoirs that are used for recreation classify as an inland waterway, so there are many places for activating. Many clubs and individual amateurs on or near the UK inland waterways obtain a Special Event Station callsign. Others operate mobile or portable using their own call signs. The primary bands will be 40m and 2m. If you would like to register or obtain more details about the event please visit, nharg.org.uk/biwota.

Another popular event, Churches and Chapels On The Air, will take place on Saturday the 10th of September between 10 am and 4 pm.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 19th of August 2022.

It looks like the Sun continued to be unsettled with an enhanced solar wind from coronal holes making itself felt here on Earth. A geomagnetic storm pushed the Kp index to six for two consecutive six-hour slots on the evening of the 17th, although it was fairly quick to recover. However, it wasn’t long before the Kp index was up to five again on Thursday afternoon.

Meanwhile, the solar flux index climbed, peaking at 131, but then declining to 123 by Thursday.

The first geomagnetic storm affected the ionosphere with critical frequencies dropping to just over 5MHz. This meant that DX was mainly closed to frequencies above 14MHz. The storm on Thursday the 18th saw an initial enhancement with MUFs over a 3,000km path hitting 21MHz.

We have had a run of geomagnetic storms, which is par for the course as we ramp up with solar cycle 25. The bad news is that this is likely to continue. It does however mean that aurora watchers and auroral radio operators will get more opportunities as the year moves on.

NOAA predicts that the solar flux index will decline to the high 90s after starting the week at around 100. It does predict relatively settled geomagnetic conditions, but as we have said before this is likely to change at short notice thanks to solar flares, and their associated coronal mass ejections, plus the effects of coronal holes.

We may have seen the best of Sporadic-E this season, although there may be weak openings on 10 metres that are best captured via FT8 and other JT digital modes.

And now the VHF and up propagation news.

It's a change-over to rather unsettled weather with Atlantic systems bringing some occasional bands of rain or showers across the country and the possibility of some rain scatter on the GHz bands.

Later in the coming week, there are hints that a new high will build in from the Atlantic to bring a return of some Tropo conditions. This may leave conditions a bit flat on VHF until after midweek or a bit beyond, so it could be worth seeking out any late-season Sporadic-E activity in the meantime.

Although Es have been rare lately, you might still find some glimmers of hope into the first week of September. In such fleeting events, you will often find the digital modes can flag up a potential direction to explore, starting on 10m and then migrating up to 6m as an event develops.

The solar activity has recently brought some auroral conditions, so remember to keep an eye on the Kp index in case further auroras materialise. As well as using the traditional 10m or 6m and occasionally 2m bands for this, you will often get a strong indication from even 80m signals sounding ‘hollow and watery’ and that is a cue to check for VHF aurora.

Meteor scatter is always a go-to mode if all else fails especially in the early mornings when random meteors are at a peak.

With high Moon declination this week we have long Moon windows, but with apogee on Tuesday, path losses are at their highest for the lunar month. 144MHz sky noise is moderate and falling but be aware that the Sun and Moon are close to eclipsing next Saturday morning meaning high Sun noise for a while.

And that’s all from the propagation team this week.

GB2RS News

Sunday the 14th of August 2022

The news headlines:

• New RadCom team announced
• Jamaican amateurs mark 60 years of independence
• Jacques, ON4AVJ, Silent Key

Earlier in the year, the RSGB announced that RadCom Managing Editor, Elaine Richards, G4LFM, was planning to retire after leading the RadCom team for 14 years. Very soon after that announcement, we had to come to terms with the sad and sudden news that RadCom Technical Editor, Giles Read, G1MFG, had passed away. RSGB General Manager, Steve Thomas, M1ACB has now announced the appointment of the new RadCom team that will continue to deliver and develop a RadCom suite of publications that supports the future of amateur radio. Ed O’Neill, M0TZX will take on the role of Managing Editor and Matt Smith, M0VWS has joined the team as Technical Editor. Ed and Matt are working very closely with Elaine and the rest of the team to ensure a smooth handover in the coming months. You can read the full press release on the main page at rsgb.org.

Amateur radio stations from Jamaica may use the 6Y60 prefix to mark the 60th anniversary since the Colony of Jamaica gained independence from the UK. For example, 6Y5WE will be using 6Y60WE.

Sad news next. The IARU has announced that Jacques, ON4AVJ, has become a Silent Key. He held many roles within the Belgian national society, UBA, and was part of the IARU Region 1 VHF Committee. He received honours from both the UBA and IARU for his work on VHF and higher frequencies. Our thoughts are with his family and friends within the wider amateur radio community at this difficult time.

This year is the 25th anniversary of the international Lighthouse and Lightship weekend that will take place next weekend, the 20th and 21st of August. The event runs for 48 hours and, as this news script was prepared, there are 325 stations registered for this year from Argentina to Malta and The Netherlands to Wales. Some are stations that have operated many times before, others like TM59LH are taking part for the first time. This station will operate from the Sandettie Light Vessel in Dunkirk Harbour.

Earlier this year, the IARU Region 1 invited amateurs to come up with an idea that could lead to more licensed radio amateurs. They have now announced the results. Joint first place was awarded to Nestor, 5B4AHZ and Christian, HB9FEU. Nestor’s idea is the Ham Radio Escape Room which is a radio-based escape room with amateur radio themes and played with teams communicating via radio. Christian’s idea was a public database of fun projects for innovation where those with little or no experience and equipment could still take part. Read the full story at iaru-r1.org where you can find out more about these projects and the other prize winners.

On Thursday it is the 70MHz UK Activity Contest from 1900 to 2130UTC. Using all modes the exchange is signal report, serial number and locator.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 12th of August 2022.

The geomagnetic disturbance we predicted last week, due to an Earth-facing coronal hole and its associated high-speed solar wind, occurred in the early hours of Monday the 8th. This pushed the Kp index to six and sparked a visible aurora that was visible from parts of the UK. It also impacted the Maximum Useable Frequency on Monday, according to the Fairford ionosonde, with it struggling to get much above 18MHz over a 3,000km path until the early evening. The Kp index remained mainly at four on Tuesday before tailing off gradually to reach two on Thursday.

Meanwhile, the solar flux index has been slowly declining, from 116 on Sunday to 108 on Thursday.

Sporadic-E has been bringing short skip to 14MHz, with paths such as the UK to Ireland and Scotland being workable at times.

The best DX has probably been on 21MHz where the Far East has been putting in an appearance, mainly on FT8. 28MHz Sporadic-E has been just that, sporadic, with some days providing great short skip to parts of Europe and others just the sound of noise on 10 metres.

Next week NOAA predicts similar conditions with the SFI in the range 104-108. Unsettled geomagnetic conditions are forecast for the 17th, 18th and 19th when the Kp index could rise to five.

And now the VHF and up propagation news.

The weather will show a more unsettled side from this weekend. The exceptionally widespread Tropo conditions of last week are likely to decay as pressure falls and by the start of the coming week, it's a slack region of low pressure over us.

This will introduce some mainly showery outbreaks of rain, but in true summer style, they could be heavy and perhaps thundery in places. This raises the prospects for rain scatter on the GHz bands and, as usual, you will need to access one of the many online radar displays to track their movement.

Recent solar conditions have varied, but some occasional aurora alerts have maintained an interest in auroral propagation. Keep a check on the Kp index to see if it goes above five or six and then look at the clusters and chatrooms for activity pointers.

Sporadic-E is still about on some days and well worth your attention for tracking down those missing grid squares. Although we are nearer the end than the start of the Es season, it can occur until about the end of the first week in September, so plenty of time left.

In the coming week, the location of the jet stream activity (often a good guide) suggests that paths may move away from Scandinavia and eastern Europe and favour Spain and the central Mediterranean.

As we slide gently away from the broad peak of the Perseid meteor shower, it's still worth checking meteor scatter propagation during the coming week.

Moon declination goes positive again on Monday, producing lengthening Moon windows. EME is for early birds this week with Moon zenith in the early hours. Path losses will fall all week, and 144 MHz sky noise is low, not reaching 500 Kelvin until next Sunday.

And that’s all from the propagation team this week.

GB2RS News

Sunday the 7th of August 2022

The news headlines:

• GB22HQ moving location
• Welsh operators wanted for GB22GW
• New Special Interest Group Manager appointed

For operational reasons, it is no longer possible to operate GB22HQ, the special event station for the Commonwealth Games, from the Smithfield site in Birmingham. The move to the Smithfield site had been a last-minute decision due to other calls on our original site by the Commonwealth Games organisers. It has been problematic due to lack of public access, high RF noise levels and ingress of water and dust on site. We’re pleased to say that GB22HQ will continue on the air for the remainder of the games thanks to members of the Wolverhampton Amateur Radio Society and the Central Radio Amateur Circle.

GB22GW is the Commonwealth Games callsign for Wales. Cath, GW4CVT is looking for volunteers in Wales to use the callsign either by CW, SSB or data modes until the 21st of August. To book a slot, visit qrz.com and search for GB22GW. There you will find Cath’s email address and the slots that are available.

The RSGB is pleased to announce that Philip Hosey, MI0MSO has been appointed as the Special Interest Group Manager. The primary role of the Honorary Officer for Affiliated National Societies and Special Interest Groups is to champion their interests and to develop a closer relationship between them and the RSGB, and the amateurs they represent.

Sad news now. Long-time GB2RS newsreader Dr David Sadler-Lockwood, G4CLI became a Silent Key recently. He was a keen member of both the Wakefield and District Amateur Radio Society and the Denby Dale Amateur Radio Society. Our thoughts are with his family and friends.

There is a new award available during August to celebrate the 200th anniversary of a Polish lighthouse. Until 31st August there will be nine special event stations on the air with SN200 or SP200 plus one letter callsigns, for example, SN200Z. Two other stations, 3Z200LHR and 3Z25ILLW, will operate only during the international lighthouse and lightship weekend, the 20th and 21st. For details on this award, go to qrz.com and look up one of the special stations involved.

Canadian radio amateurs have gained access to two new bands recently. They now have access to 472 to 479kHz with a maximum of five watts EIRP, and 5.3515 to 5.3665MHz with a maximum of 100 watts EIRP. Canadian amateur radio is a Secondary radio service on these bands.

The YOTA Team Croatia has created an award available for working youngsters at the YOTA Summer Camp. Each QSO with a 9A YOTA station in a different band or mode combination earns you one point. Duplicates do not count. Valid QSOs will be made from 0000UTC on the 6th to 2359UTC on the 13th of August. You may even get to contact one of the four young people the RSGB has sent to the Summer Camp. Go to iaru-r1.org and click on the YOTA Summer Camp news item for details on the award.

Next Sunday, the 14th, the fifth 70MHz Cumulative contest runs from 1400 to 1600UTC. Using all modes, the exchange is signal report, serial number and locator.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 5th of August 2022.

Last week was characterised by a solar flux index of around 100 but reasonably settled geomagnetic conditions. The SFI had a low of 94 on Sunday and a high of 100 on Thursday. The Kp index has been in the range of one to four, with more settled conditions being experienced in the second half of the week.

Daytime critical frequencies have ranged from lows of 5MHz and highs of up to 7MHz. As a result, skip distances on 40m have varied dramatically, and often very quickly. This has caught out some amateurs who have found solid inter-G conditions one minute, but fast fading as the critical frequency has dropped leaving only European stations workable.

As a guide, keep one eye on propquest.co.uk for the current critical frequency and extrapolated maximum usable frequencies over different path lengths. Only then can you make sense of daytime 40m propagation.

Sporadic-E is still putting in an appearance but is far less prevalent as we head into August. It may still be usable for weak signal modes like FT8, but loud SSB signals from Europe may be less prevalent.

Next week, NOAA's Space Weather Prediction Centre predicts that the SFI will be in the range of 98-100 again. That is, it doesn't think we will get any rapid increases in sunspot numbers over the next week. The Kp index is forecast to be in the range 2-3, which means moderately settled geomagnetic conditions. However, a coronal hole on the Sun's equator may cause some problems just after the weekend.

So daytime F2-layer MUFs over 3,000km paths may be up to 18-21MHz. Any short-skip 10m openings are therefore likely to be Sporadic-E.

And now the VHF and up propagation news.

The basic pattern continues unchanged with high pressure favouring southern and eastern areas and lows with their fronts affecting the northwest. Occasionally weakening cold fronts drift southeast. This will provide further tropo opportunities, particularly during the hot and humid periods and in this case, a good cloud cover near the surface is a good indicator.

The preferred paths would most likely be across the North Sea to Denmark, Germany and Netherlands and across the Channel to the continent. A more extensive option could be to the south across Biscay to Spain and beyond to the Canaries and mid-Atlantic. Rain scatter is unlikely for most areas except for very isolated showery developments on the weak cold fronts over central parts of the country.

The Sporadic-E season continues to trickle charge log books with occasional openings. Although the jet stream activity is relatively weak over central and southern Europe, it has been shown that it is sometimes more important that the pattern is moving, however weak.

The stronger flow appears to favour paths across the north of the UK to Iceland and Greenland and towards Scandinavia and the Baltic states. Check the daily blogs onPropquest.co.uk, which continue through August, for the latest thoughts on the daily jet stream charts.

Next week sees the peak of the Perseids around the 12th of August and even if you don't have the gear for meteor scatter it's hard to beat watching meteors on a warm summer evening. The Sun has continued to exhibit some marked coronal holes, a potential source of the solar wind surges that produce the aurora, so be aware of this.

The Moon passes a milestone this month with perigee and minimum declination coinciding. From then onwards, perigee and maximum declination start to drift closer again, but it’s not until September 2026 that they coincide. All week the Moon's elevation is low at its zenith and the Moon is only visible for a few hours out of the 24. 144MHz sky noise is high, reaching 3000 Kelvin on Monday.

And that’s all from the propagation team this week.

GB2RS News

Sunday the 31st of July 2022

The news headlines:

• Commonwealth Games station on the air
• Listen out for YOTA Summer Camp stations
• RadCom Basics available to RSGB Members

The RSGB is excited to be supporting the Commonwealth Games with special event station GB22HQ. This is being activated from the Birmingham Smithfield site where the Beach Volleyball, 3x3 Basketball and Wheelchair Basketball will take place. It is also the starting point for the Marathon. GB22HQ will run for the duration of the Games until the 8th of August. There are two stations using wire aerials for 40m and 30m, plus a Yagi for the five bands from 20m to 10m. During the first day of operation, the station was on the 10 to 40m bands and pile-ups were evident. The operators say 40m SSB during the daytime is probably the best place to look for them. See more at rsgb.org/cwg.

As part of the Youngsters On The Air 2022 summer camp from the 6th to the 13th of August, seven call signs will be heard. 9A22YOTA will operate from the camp in Croatia for the full duration. 9A1YOTA will join remotely on the 8th alongside 9A2YOTA on EU-136. 9A3YOTA will be on the air on the 10th, together with 9A4YOTA. 9A5YOTA will be on the air on the 12th. 9A100QO will work the QO100 satellite from all locations.

The latest edition of RadCom Basics for July 2022 is now available. There are more topics to help newcomers and those looking to brush-up.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 29th of July 2022.

We’ve had a week of lower solar flux indices, despite a smoothed sunspot number in the 50s. The sunspots we have had have been relatively small and pretty inconsequential.

The week started off with an SFI of 107, but then declined to 98 by Thursday. The good news is that we have had relatively settled geomagnetic conditions after a wobble at the weekend due to a high-speed solar wind stream.

Other than Sporadic-E events, the maximum usable frequency over 3,000km has struggled to get up above 18 or sometimes 21MHz during daytime. But, as we have said before, night-time MUFs have remained seasonally high, topping 14MHz over a 3,000km path most nights.

Next week, and as we enter August, we can expect more of the same. The solar flux index is predicted to rise slightly to perhaps 115 by next weekend.

But the prediction is also for more unsettled geomagnetic conditions with a maximum Kp index of four this weekend and again later in the week. This is most likely due to high-speed solar wind from coronal holes once again.

So best of luck with the IOTA contest this weekend, which will probably be dominated by operators on 20 metres with occasional Es openings on the higher bands.

And now the VHF and up propagation news.

There have been some fleeting signs of the continuing Sporadic-E season, but events are not so commonplace in this second half of the summer. This means being alert to the typical operating windows, which traditionally are early or mid-morning and again late afternoon/early evening. At the heart of these events will usually be a weather feature, such as a jet stream, whose turbulence creates a wave motion in the atmosphere that can cause varying wind flows in the E region some 100km above the weather, and are a big contributor to the formation of Es.

In this coming week, the jet streams are very limited so it's not looking too favourable for major Es events.

The weather pattern shows lows near the northwest of Britain driving fronts across the north, and at the same time precluding the development of Tropo, since it does not allow the development of high-pressure systems.

However, conditions in the south are a bit more supportive, so there could be occasional Tropo, especially over sea paths around the UK. There is a hint that the second half of the week will see the development of a large high more generally over the UK, so that's the time for Tropo to shine.

The other modes such as rain scatter are not looking too strong since the frontal cloud bands tend not to be as effective as heavy thundery showers, but it's always worth checking for aurora and meteor scatter as we move into August and within reach of the broad peak of the Perseids meteor shower.

It’s a good week for EME with positive Moon declination until Tuesday and falling path losses, but we are still more than a week from perigee. 144MHz sky noise is low but slowly increasing all week.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 22nd of July 2022.

Last week was almost a repeat performance of the previous week. We had very disturbed geomagnetic conditions on Tuesday, with the Kp index hitting five. But then other days, like Wednesday, when conditions were much more settled. The solar flux index declined from its high of 176 last Saturday to 133 on Thursday. The Sun’s surface is still peppered with spots, but they are all fairly small and innocuous.

Nevertheless, there have been numerous C-class flares happening on a daily basis and two M-class flares last Saturday.

The popular press has been running their usual horror stories about CMEs hitting the Earth, threatening all sorts of doom and gloom. But to be honest, for radio amateurs, it’s business as usual.

Sporadic-E had been most prolific earlier in the week with some relatively short-skip signals being stable over long periods. The ED4YAK beacon in Spain on 28.251MHz has often been audible for hours.

Next week NOAA predicts that the SFI will remain in the mid-130s, but predicts that geomagnetic conditions may be unstable over the weekend, before settling on Tuesday. If this is the case we can expect reduced MUFs over the weekend and a general lacklustre feel to HF, until the Kp index reduces again.

Make the most of the Es season while it lasts, as we may have seen the best of it, and we can’t expect an upturn in F2-layer propagation until mid to late September.

And now the VHF and up propagation news.

It looks like a bit of a propagation mode mixture this coming week with something for everyone. It begins with a continuation of the typical summer warmth rather than the extreme conditions last week. Over northern areas, where low pressure remains close-by, we’ll see a few showers that might bring GHz band rain scatter opportunities. There will be a few showers in the south too, but also with a period of the Azores high building a ridge across southern Britain. This could bring some occasional Tropo throughout the week to southern areas, interspersed with isolated rain scatter opportunities in any showery interludes.

The Sporadic-E season continues apace with a bit of an uptick again last week, bringing some strong signals from south-eastern Europe. Summer jet streams are often rather scarce in more southern latitudes, but can occur fairly frequently over the UK and northern Europe. That will probably be the case in the coming week and suggests that paths towards Scandinavia, the Baltic states and eastern Europe will do best.

With four minor showers peaking around the 28th to the 30th, meteor scatter is worth trying, particularly around dawn, as will aurora propagation modes in view of the current unsettled solar activity.

The Moon is at maximum positive declination on Tuesday and also at apogee, its furthest point from Earth, so Moon windows are long and path losses are at their highest. 144MHz sky noise is low to moderate all week, but Thursday sees the Sun and Moon close in the sky, making EME very difficult due to sun noise in the antenna beam width.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 15th of July 2022.

We had another rocky journey last week in terms of HF propagation. The solar flux index climbed from 137 last Saturday to 165 by Thursday, which should have brought better conditions. But the Earth was plagued again by unsettled geomagnetic conditions, with the Kp index hitting four on Monday the 11th and five on Tuesday the 12th. This was due to an enhanced solar wind, which hit a velocity of 564km per second and had a strongly south-pointing Bz magnetic field. This allowed it to more efficiently couple with the Earth’s magnetic field allowing plasma to pour into the polar areas.

HF conditions were typical for this time of year, with lower maximum frequencies during the day, compared with winter, but higher MUFs at night.

Daytime F2-layer MUFs over a 3,000km path has generally been between 18 and 21MHz during the day, falling to 10 to 14MHz at night. But the early hours of the 11th were particularly good with the MUF staying above 15-16MHz.

The moral of the story is if you should wake up in the middle of the night, check out your HF radio, you might get a pleasant surprise.

Sporadic-E remains the dominant mode for 10-metre propagation, bringing strong short-skip contacts around Europe and the potential for multi-hop DX.

Next week NOAA predicts that the SFI will decline to the 130s, although their predictions have not been too accurate recently. We can likely expect reasonably unsettled geomagnetic conditions with a minimum Kp index of three.

With the current sunspot activity, the solar wind is unlikely to remain calm for long and more solar flares are very likely.

And now the VHF and up propagation news.

The current very hot and humid weather means that Tropo is fairly widespread. This can be a significant feature over surrounding seas as hot dry air from the land drifts out across a cooler moist layer of air near the sea surface giving an almost continuous strong Tropo.

This affects paths across the North Sea, the English Channel and the Irish Sea as well as farther afield across Biscay and south past Portugal. The Mediterranean is a hot spot of Tropo during the summer, and long east-west paths are possible if you take a rig on holiday.

Closer to home, these favourable Tropo conditions come to an end by midweek as low pressure moves into place over the UK and brings a chance of heavy thundery showers, with associated GHz band rain-scatter chances.

Sporadic-E is still prevalent in mid-July and the jet stream pattern probably favours paths to the Baltic and Scandinavia. A high Kp index tends to suppress Es chances and this has been rather volatile lately. It’s worth checking this periodically, and the silver lining of a higher Kp index is a chance of auroral propagation.

As we move towards the end of the month, all four relatively-small July meteor showers are still active. The largest of these is the Southern delta-Aquariids, peaking on the 30th of July with a medium Zenithal Hourly Rate of 25. Remember that random meteor activity is always there and is best around dawn.

Moon declination goes positive on Monday and we passed perigee last Wednesday, so Moon visibility time and path losses will increase this week. 144MHz sky noise is low all week.

And that’s all from the propagation team this week.

Also starting on Saturday the 16th is the CQ World Wide VHF contest. More details are in the main news.

Next Sunday, the 17th of July, the International Low Power Contest runs from 0900 to 1600UTC. It is CW only on the 3.5, 7 and 14MHz bands. The exchange is the signal report, serial number and your transmit power.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 8th of July 2022.

It was a mixed bag of HF propagation last week. The solar flux index was adequate rather than outstanding and a large elongated coronal hole contributed to the Kp index hitting five on the 4th of July. However, things became more settled geomagnetically later in the week with the Kp index back down in the ones and twos. The SFI slowly climbed up to 115 by Thursday, thanks to some new spots appearing over the Sun's limb.

There was some minor solar flare activity, but no coronal mass ejections were logged. The net result was quite good conditions with the MUF over a 3,000km path reaching up to 24MHz at times. This changed on Thursday, however, when the Kp index rose to five due to the incoming enhanced solar wind.

Earlier in the week, there were some reports of trans-Atlantic contacts on 10 metres as well as extensive Es openings into Europe. If the Kp index can once again go low it does rather bode well for the IARU worldwide contest this weekend.

Next week, NOAA predicts that the SFI will remain around 115 for a time, but may then drop back to around 108 as the week progresses.

Barring any CMEs, NOAA predicts that the Kp index may remain low, at least until the 15th and 16th of July when it could rise to four again. However, a coronal hole on the Sun's equator will become Earth-facing on Saturday, so we might expect the Kp index to climb around Monday. As always, this is hard to predict.

And now the VHF and up propagation news.

The coming week is likely to see high pressure over southern Britain with occasional lows crossing north of Scotland with rain and stronger winds. This raises the prospect of GHz band rain scatter as the fronts move south and break up into showers over northern England and North Wales.

The main feature of the next week is the high pressure and the prospects of fairly widespread Tropo. This could extend south and east into the continent and south across Biscay to Spain and beyond. Contacts with the Canaries or perhaps even farther to Cape Verde for the big stations in the southwest of the UK and Southern Ireland are possible.

The high summer Sporadic-E season is in full swing although somewhat reticent compared to other years. The jet stream activity is not as widespread as earlier in the season now that summer conditions with lighter upper winds are becoming established, but there should be a preference for paths to Scandinavia and southeast Europe.

The other remaining modes of aurora and meteor scatter are of course available given the right conditions. The minor Alpha-Capricornids meteor shower should be active but with a low ZHR of around five. Solar output has been affecting the Kp index recently, so check the various space weather websites for details of further events.

The Moon is at minimum declination on Tuesday and perigee on Wednesday so short Moon visibility windows and low path losses are the stories for EME this week. 144MHz sky noise is high for most of the week.

And that’s all from the propagation team this week.

The UK Six Metre Group’s Summer Marathon is still taking place, ending on the 2nd of August. Using all modes, stations exchange their 4-character locator.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 1st of July 2022.

Last week was not a good one for HF propagation in general. There were many complaints from amateurs about poor conditions that can be explained by a combination of low solar flux levels and unsettled geomagnetic conditions.

The SFI started the week last Sunday at 102 but then dropped to 98 the following day. It subsequently continued to drop, reaching 92 by Thursday. At the same time, the Kp index reached five and it continued to be unsettled into Monday.

The effects on the ionosphere were not good, with maximum usable frequencies over a 3,000km path struggling to reach 18MHz. Conditions improved as the week went on with F2-layer MUFs back into the 21MHz region by Thursday.

This is fairly typical of Summer ionospheric conditions, leaving Sporadic-E as the likely main propagation mode on 10 metres until the Autumn.

Next week NOAA predicts that the solar flux index will start to climb again, perhaps peaking at 140 by the 11th of July. Geomagnetic conditions are predicted to be stable with an average Kp index of two, until the 10th when it could reach four.

As long as we don’t have any coronal mass ejections during this time this could mean slightly better F2-layer conditions next week. As always, Sporadic-E may provide loud short-skip signals on the upper bands. Watch out for multi-hop Es paths which are harder to predict.

And now the VHF and up propagation news.

With VHF National Field Day, this weekend we would all like conditions at their best, and with the Sporadic-E season still in full swing, that's a possibility.

The position of the jet stream is often instrumental in defining the directions that perform for Es and this weekend it looks to be a close-by jet stream over the near continent. This means paths towards central and southeast Europe plus the Baltic and Scandinavia. You might be able to get some notion of how it's developing by Googling and looking at the ionosonde from Dourbes in Belgium for spikes in the foEs trace.

With low pressure close to Scotland over the weekend, it's only southern UK under a weak ridge that will see any Tropo. This will typically be better overnight and around the coasts for paths into the continent across the North Sea or the English Channel.

So unless you are on the coast, your tropo options will diminish early this Sunday morning once the solar heating starts to break down the overnight temperature inversion.

The UKAC 144MHz contest on Tuesday evening looks a better prospect with high pressure nudging towards western Britain and a chance that conditions may be slightly up, even for more northern stations.

With some showery episodes likely, rain scatter is always a possibility, but decaying as the high moves in later. The clusters should tell you if aurora or random meteor scatter are viable options.

Just one meteor shower this week, the July Pegasids active from the 4th of July to the 14th, but its Zenithal Hourly Rate is low at around five. Meteor showers in July are at their best around the end of the month, particularly the Southern delta-Aquariids, peaking on the 30th of July. The maximum ZHR of this shower is around 25 over two days. The radiant of this shower is above the horizon in the UK during the night and early morning.

Moon declination goes negative this coming Wednesday so expect lower peak elevation and shortening Moon visibility windows for EME. Path losses are dropping as we head towards perigee a week on Wednesday. 144MHz sky noise is low all week.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 24th of June 2022.

As predicted, the solar flux index fell back this week, but it didn’t fall as low as experts predicted. On Thursday, it stood at 129, but with three sunspot groups about to rotate off the visible surface, it looks like it may now fall lower.

We are now well and truly into the summer season for HF propagation, which can be characterised as providing lower maximum usable frequencies during the day, but higher MUFs at night. Sporadic-E remains the most common mode of propagation on the higher bands, with F2-layer MUFs over 3,000 kilometres generally not exceeding 21MHz for most of the day. But more on Sporadic E in the VHF segment of this report.

The good news is that 20 metres stays open later, often providing paths over 3,000km up until midnight. The higher bands, that is 17 metres, 15 metres and perhaps 12 metres, may generally provide good paths to South America in the evenings, with 20-metre paths being the last to close.

But we’re afraid we may have to wait until September to see good reliable paths into North America on HF once again.

Next week, NOAA predicts that the SFI will remain around the 100 mark, so we may expect lower MUFs again, apart from Es openings. Geomagnetic conditions should generally be quiet with a maximum Kp index of two once we get over any disturbance this weekend due to a high-speed solar wind stream.

And now the VHF and up propagation news.

The recent very warm and humid weather has produced some occasional Tropo with the British Isles being on the edge of high pressure, mainly over the near continent. This may still happen occasionally in the coming week, but the fundamental characteristic for next week is low pressure and unsettled weather over the UK. This will produce some rain, with thunderstorms a possibility, and rain scatter will crop up as a useful mode on the upper GHz bands at times.

The many online weather radar displays will allow you to keep a track of storms as they develop. When low pressure is centred over the country the showers may be longer-lasting and not decay overnight, so this period looks more promising than the usual mainly daytime shower distribution.

The Sporadic-E season is in full swing, but in a rather restrained way since openings have been fairly limited and often fleeting. The presence of jet streams on the weather charts is a good indicator of regions where Es is more likely and the coming week offers a good variety of options, so if Sporadic-E is hard to find then perhaps other parameters may not be optimal; for example, the meteor input is a crucial component in the development of Es. Check the daily conditions for jet streams on the Propquest.co.uk EPI maps and Es blog.

The June meteor showers, mentioned last week, continue into early July so keep checking meteor scatter conditions between the Es.

With the Moon at maximum declination on Wednesday, Moon windows are long this week. Today, Sunday the 26th of June, the Moon is at apogee, or its furthest point from Earth, so path losses are at their highest, and for around four hours after UK Moonrise on Wednesday the Sun is close to the Moon so noise will be high at that time.

And that’s all from the propagation team this week.

Sunday the 19th of June 2022

The news headlines:

• Region 1 Monitoring Service newsletter
• IARU VHF and up matters
• GI-QRP Convention

The latest IARU Region 1 Monitoring Service newsletter detailing intruders in the amateur bands is available at iaru-r1.org. Radars continue to be the most numerous and harmful intrusions in our bands. For the last couple of months monitoring have been receiving signals whose function they have not yet been able to identify. The most common one has a bandwidth of about 8kHz, seems to consist of a central carrier and is most frequently found in the 20 and 40m bands.

For those with a particular interest in VHF matters, the IARU Region 1 VHF+ Newsletter number 89 is available from the same website, iaru-r1.org. It contains details of the interim hybrid meeting due to be held during the radio show in Friedrichshafen, Germany. Subjects for discussion include preparation for the ITU World Radio Conference, WRC23, particularly regarding the 23cm band. It also has details of IARU VHF and up contests and trophies.

Throughout June, many UK radio amateurs may use the letter Q in place of the Regional Secondary Locator. If you would like to join them, the free-of-charge Notice of Variation to your licence that is needed is available via the RSGB website, see rsgb.org/jubilee. If you would rather, you may use the suffix /70 to celebrate the Queen’s Platinum Jubilee. An NoV is not necessary for the /70 addition to your callsign. There are two awards available for logging or working stations using both the Q RSL or /70 suffix, see rsgb.org/jubilee and look at Award 70. The GI-QRP Convention will take place on Saturday the 25th of June at the Tandragee Golf Club. This event is supported by the G-QRP Club. There will be trade stands, talks and presentations relating to QRP construction and operating. The talks will be streamed live online for those unable to attend. A Buildathon will also take place, where participants, under supervision, will construct a Morse tutor. Advance booking for the Buildathon is advised. There are concessionary prices for junior constructors. Doors open at 9.30am and the event closes at 5pm. Details are at gqrp.com, just click on the GQRP Convention tab on the left-hand side.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 17th of June 2022.

We said that last week’s relatively low solar flux index wouldn’t last very long and it looks like we were right. This week we have had an SFI that started at 121 and just kept climbing, peaking at 149 on the 15th. Unfortunately, we have also had some plasma to contend with thanks to the combined effects of a coronal hole high-speed stream, along with a bright coronal mass ejection observed on Monday. These pushed the Kp index to five on Wednesday the 15th.

Luckily a long-duration eruption, LDE, measuring M3.4 detected around active region 3030 on Monday was directed away from Earth and missed us completely. But it does show that we can expect more in the way of CMEs as we head towards the peak of solar cycle 25.

F2-layer MUFs over a 3,000km path have regularly exceeded 21MHz and often 24MHz. There have also been some occasional 10m F2-layer openings, with Sporadic-E and multi-hop Es events as other likely modes of propagation. As a result, there have been many reports of DX being worked, including Vasco, 7Q7CT in Malawi and Harald, 9X2AW in Rwanda on 10-metre FT8.

The USAF predicts that the SFI will be around 136 this Sunday, falling back to 100 as the week wears on.

Geomagnetic conditions are predicted to be unsettled around the 24th, although we could be in for a rough ride overall next week due to any unexpected CME from one of the numerous sunspots that have been flaring recently.

And now the VHF and up propagation news.

We ended last week with high pressure nearby for southern Britain with a low-pressure north of Scotland pushing a cold front south. So Tropo in southern areas is getting displaced as the pattern becomes more unsettled and after some very high temperatures.

The bulk of the coming week sees high pressure off to the west and a cooler north-westerly flow over the country with some showery periods too. This presents the prospect of rain scatter, but somewhat limited Tropo conditions, chiefly for western-most parts and Ireland down to Biscay and Spain.

The Sporadic-E season is in full swing, although in the last week conditions have not been quite so exciting, apart from the magnificent opening to the States last Sunday evening. Widespread activity as far as Mexico and Texas doesn’t happen often and plots of the weather patterns showed that there were multiple jet stream areas of activity to make up the required sequence of four or five hops of Es.

Since the weather pattern driving this was not exceptional, it suggests that it could happen again, so perhaps keep the notion of checking 6m as late as mid-evening 2000-2200UTC in your back pocket during the rest of the month.

There are still plenty of meteor showers to fill in between the Sporadic-E in June. The Aretids, Zeta-Perseids, Beta-Taurids and June Bootids are all active this week. The latter is generally low activity, but it produced unexpected activity in 1998 with a ZHR up to 100 for more than half a day and in 2004 with a ZHR up to 50 over a similar period.

Moon declination goes positive again on Wednesday, and we are past this month’s perigee, so increasing Moon availability and increasing path losses is the story for EME enthusiasts this week. 144MHz sky noise is low, not exceeding 300 Kelvin until Thursday.

And that’s all from the propagation team this week.

Amateurs are reminded that IARU Region-1 is holding its Interim Meeting on the 23rd of June. As outlined in the recent June RadCom, feedback is welcomed on proposals for global HF band changes to accommodate growth in digital modes and related matters. The meeting will also consider a series of Spectrum and EMC matters. The RSGB has a consultation page with the background and document links available at thersgb.org/gb2rs/017. Feedback should be posted to the RSGB-Workshop forum groups.io/g/RSGB-Workshop by end of Sunday the 19th of June.

Gateways On The Air event will be on the air between the 11th and 19th of June and is hosted on the FreeSTAR Multimode Network. The aim of the event is to promote increased RF voice communications via analogue and digital Simplex Gateways. Licensed amateurs are encouraged to go outside into the fresh air, either when portable or mobile, to work a Simplex Gateway from a location of public interest. GOTA is a “just for fun” event with two categories for both Activators and Chasers. To connect your Simplex Gateway to the event please email Oscar@freestar.network. For more information visit GOTA.org.uk.

Tickets are now on sale for some of the things going on at the GI-QRP Convention; the first to take place in Northern Ireland for many years. This is being organised by members of the RSGB Region 8 team, in conjunction with the G-QRP Club. The event takes place at the Tandragee Golf Club on the 25th of June. There are talks, trade stalls and a number of Buildathon workshops. There is no need to book if you just wish to attend in person. You do need to book if you want to have a buffet lunch or join in the Buildathon at the event or join the live streaming of the talks and have access to the recordings after the event, from home. Details gqrp.com/GI_Convention.htm.

A new Kenwood TM-D710GA transceiver has been installed on the International Space Station. The old amateur radio equipment was dismantled, and the new kit will be used for transmitting Slow Scan TV images on 145.800MHz FM, probably using the SSTV mode PD-120. The signal should be receivable on a handheld with a quarter-wave whip. You can get predictions for the ISS pass times at amsat.org/track.

The Oscar 100 Award is an international award aimed at promoting experimental activities and radio contacts via the geosynchronous satellite QO-100. Participants should contact as many stations and DXCC Countries as possible via the satellite. The award lasts six months, ending at 23:59UTC on 31 December. Details are at arifidenza.it.

The UK Six Metre Group’s Summer Marathon runs until the 2nd of August, with contacts on the 50MHz band exchanging your 4-character locator.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Wednesday the 10th of June 2022.

The sunspot number on Wednesday was zero with a solar flux index of 100. Given the high flux numbers, we have been seeing this as a little disappointing. The last time the visible disk was officially spotless was December 2021. The upside is that there has been little risk of coronal mass ejections and the Kp index has remained below three for more than a week.

Anecdotal reports showed that the upper HF bands have been quite quiet.

A couple of potential regions are currently behind the Sun’s east limb and will begin to turn into view during the next few days. NOAA predicts that the SFI will increase slightly to perhaps 110 at first and then up to 125 by the 19th of June.

While F2-layer openings may be peaking at around 15 metres this month, Sporadic E should bring lots of strong short-skip openings from 14MHz to 28MHz. June is a good month for Es openings. Check out 10 metres at peak Es times of mid-to-late morning and mid-to-late afternoon. Early evening can also bring surprises as well. For novelty’s sake alone, listen out for the HB9HD 10m repeater on 29.650MHz in Switzerland, complete with its musical box ident!

And now the VHF and up propagation news.

We start the week with high pressure over mainland Europe. The Hepburn tropo charts predict that we may see lift conditions over southern England this weekend. Paths from locations south of London may be possible into northern France and the low countries, with a slight possibility of extended tropo towards southern France. These opportunities may tend to dissipate as we head into next week.

For stations in the north of England, there may be fewer opportunities for tropo DX as low pressure is predicted to pass to the northwest of the country. Microwave rain scatter opportunities may be available though. From mid-week onwards, the most likely scenario is for low pressure to the north of the UK to clear as high pressure builds from the west, which may bring tropo opportunities to northern areas.

There are always Sporadic-E opportunities available in June, with many good openings reported over the last seven days.

The first half of June is one of the best periods of the year for daylight meteor scatter-DXing but is often masked by Sporadic-E propagation. We have already seen the peak of two daytime meteor showers, namely the Arietids and zeta-Perseids last week, but as they are both characterised by a broad maximum and high ZHR value, they continue to be useful. The best time for them is early morning for North to North-East and South to South-West directions, and early afternoon for North to North-West and South to South-East directions.

With the Moon approaching perigee, its closest point to Earth, on Tuesday, path losses for EME will be at their lowest. This sadly coincides with minimum declination on Wednesday, with short moon visibility windows and low peak moon elevation. 144MHz sky noise will peak on Tuesday and Wednesday at a little over 3100K.

And that’s all from the propagation team this week.

GB2RS News Sunday the 5th of June 2022

The news headlines: Amateur radio to be shown on television Thank you to all the Society’s volunteers Platinum Jubilee activities underway

The hobby of amateur radio, and portable operating in particular, will receive some television coverage today, Sunday the 5th of June. The long-running BBC Countryfile programme airs at 6 pm on the main BBC 1 channel. It will be based from Flat Holm Island in the Bristol Channel, the site of Marconi's first radio transmissions over the sea. Presenters Ellie Harrison and Matt Baker will be with leading Summits on the Air operator Ben Lloyd, GW4BML as he sets up a portable station on the island in order to contact SOTA activators on hill and mountain summits around the UK. Volunteers Week takes place between the 1st and the 7th of June every year. It's a chance for the RSGB to recognise the fantastic contribution volunteers make to the work of the Society. From news readers to the National Radio Centre, the regional teams to committees and everything in between, the RSGB would like to thank the hundreds of people who make a difference in amateur radio every week, not just during Volunteers Week. If you would like to join them, go to rsgb.org/volunteers to see what vacancies are available. The RSGB’s Platinum Jubilee activities have started with the GB70 Special Event Stations up and running. The call signs to look for are GB70E in England, GB70M in Scotland, GB70W in Wales, GB70I in Northern Ireland, GB70J on Jersey, GB70U on Guernsey and GB70D on the Isle of Man. You can find out more about these special events at gb70.co.uk. Many amateurs are already using the Regional Secondary Locator, the letter Q. If you would like to join them, the free-of-charge Notice of Variation to your licence that is needed is available via the RSGB website, see rsgb.org/jubilee. If you would rather, you may use the suffix /70 to celebrate the Queen’s Platinum Jubilee. An NoV is not necessary for the /70 addition to your callsign. The RSGB’s Tonight@8 will be live on Monday the 6th of June. Professor Ian Morison, G0DMU will give a review of the history of Jodrell Bank, one of the world’s premier radio astronomy observatories. From its founding in 1945 through the completion of the Mk I radio telescope in 1957 to the building of the Merlin array in the 1980s and 1990s, Ian will discuss some of its most exciting discoveries. Due to recent poor propagation on the original 3727kHz frequency and increasing local background noise levels on the 80m band generally, the National Radio Centre net has moved to 7130kHz. The net is on air every weekday morning starting at 10.30 am on 7130kHz. The net is open to all licensed radio operators, whether to join in with the chat or just for a signal report. Belgium's communications regulator has said 50.200MHz and 51.075MHz will be used until the 18th of June during a military exercise in Elzenborn. In Belgium, the amateur radio service has a secondary status in this band with the military services having primary status. Radio amateurs are asked to avoid the use of these frequencies if possible and to listen carefully to whether the frequency is in use if they still wish to use the frequencies concerned.

Also next Sunday, the 12th, the Practical Wireless 2m QRP contest runs from 0900 to 1600UTC. It is phone only and the exchange is signal report, serial number and locator. The maximum power allowed for this contest is 5\W. The UK Six Metre Group’s Summer Marathon runs until the 2nd of August, with contacts on the 50MHz band exchanging your 4-character locator.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Wednesday the 1st of June 2022. What a difference a week makes! Last week we were looking at a solar flux index of 137 and a mass of sunspots. This week the SFI is standing at 101 with only three active regions visible, and one of those is about to rotate out of view. Geomagnetic conditions have been relatively stable, but a little unsettled with a maximum Kp index of three over the past few days as this report was being prepared. The solar wind stream remained elevated above 500km/s due to a coronal hole stream combined with possible weak Coronal Mass Ejections, or CME, effects. As a result, HF conditions have been a little lacklustre with the Chilton Ionosonde showing a critical frequency of between four and five Megahertz. This equates to a maximum usable frequency of around 18-21MHz over a 3,000km path. As we said, nothing to write home about. But all is not lost as the experts feel this will be a short-lived decline in solar activity and normal service will soon resume! NOAA thinks the SFI will decline a little more by the end of this week, before coming back with a roar from around Tuesday the 7th of June. It predicts the SFI could be 110 on Tuesday the 7th and then rise to 150 by the 14th. So next week could see the bands opening up again, at least for a while. Geomagnetic conditions are predicted to remain quiet with a maximum Kp index of two, at least until the 10th when it could rise to perhaps four or five. It looks like the Jubilee weekend may offer fairly flat HF conditions, but this may improve as we head into next week.

And now the VHF and up propagation news. There are no signs at the moment of really strong long-lasting areas of high pressure so any Tropo is likely to be temporary. On today's forecast charts, the only one that shows up develops over Scotland during the holiday weekend but declines as the weekend finishes. The rest of the weather story is focused upon showery activity and with the prospect of some being heavy and thundery, it bodes well for rain scatter, but could also play havoc with HF CW NFD static levels. The early days of June are regarded as prime time for Sporadic-E, and with this season getting off to a slow start, it's high time we saw some activity. There are a few jet stream segments over Europe during the week to come, but nothing looks too strong. This may be compensated for by the increase in the background meteor input in this period and, hopefully, there will be plenty to celebrate. After the excitement of last week’s “will they, won’t they” Eta Aquarids meteor shower, this week is going to be something of a back to normal situation. June is usually a slow month for meteors with no major showers. However, the daytime Arietids, which is a minor meteor shower, may provide some useful radio reflections on Tuesday and Wednesday, the 7th and 8th. Sky noise will be quite low this week with the Moon full next Tuesday, the 14th of June. Declination reduces throughout the week as the moon moves towards perigee. Path loss for Moonbounce will reduce as the week progresses. Once again, low declination will favour stations with little or no antenna elevation, potentially increasing operation time beyond that around moonrise and moonset. And that’s all from the propagation team this week.

The news headlines: Jubilee call signs go live from the 1st GB70 special event stations ATV columnist interviewed

It isn’t long now until the RSGB’s Platinum Jubilee activities kick-off. You can start using the Regional Secondary Locator, the letter Q, on the 1st of June. The free-of-charge Notice of Variation to your licence that is needed is available via the RSGB website, see rsgb.org/jubilee. If you want to retain your usual Regional Secondary Locator you may use the suffix /70 to celebrate the Queen’s Platinum Jubilee. An NoV is not necessary for the /70 addition to your callsign. The GB70 Special Event Stations will be operating next weekend, including the bank holidays, and you can get a special QSL card for contact with any of the GB70 stations. The Guernsey club's use of the QO-100 satellite is causing a lot of interest. The call signs to look for are GB70E in England, GB70M in Scotland, GB70W in Wales, GB70I in Northern Ireland, GB70J on Jersey, GB70U on Guernsey and GB70D on the Isle of Man.

Check out the rules at prideradio.group/contest The RSGB National Field Day runs from 1500UTC on the 4th to 1500 UTC on the 5th of June. Using CW only on the 1.8 to 28MHz bands where contests are permitted, the exchange is signal report and serial number. Next Sunday, the 5th of June, the UK Microwave group’s Low Band Contest runs from 1000 to 1600 UTC. Using all modes on the 1.3, 2.3 and 3.4GHz bands, the exchange is signal report, serial number and locator.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 27th of May 2022. The solar flux index remained above 130 last week, being at 137 on Thursday as this report was prepared. It peaked at 165 on Sunday and reached a massive 180 on Wednesday the 18th. All this means that DX is workable on the upper HF bands with the 3D2RRR DXpedition on Rotuma Island near Fiji being chased from the UK. A little closer to home, V51WW in Namibia has also been putting in an appearance. Sporadic-E has also seen some short-skip signals from Europe on 10 metres, but we haven’t seen many rock-crushingly strong signals as yet. The Sun remains very active with a CME associated with an M1.3 flare detected around region 3016 at 1824UTC on Wednesday, the 25th of May. The bulk of the plasma released was off the Sun-Earth line, although closer examination revealed a fainter Earth-directed component was evident and could sweep past Earth within 48-72 hours. If correct, this means the Kp index may rise this weekend. Coronal mass ejections remain a risk to HF propagation with a massive one on the far side of the Sun being observed on the 24th of May. We have been lucky last week with the Kp index generally in the ones and twos, that is, indicating settled geomagnetic conditions. But we think it is only a matter of time before we get hit with a “big one”, which could cause disruption and a general reduction in maximum usable frequencies. Next week, NOAA predicts that the SFI may decline into the 130s or even 120s. In fact, by the 5th of June, it thinks it will be at a low of 114 before rising again. Luckily, NOAA also predicts that the Kp index will remain low. This will help the ionosphere develop and should bring good conditions. However, we issue a caution that a single Earth-directed CME could put paid to low Kp indices and bring disruption. As always, keep an eye on solarham.com for updates.

And now the VHF and up propagation news. The next period of weather is dominated by high pressure, although not in exactly the right place for good Tropo conditions everywhere. The main position of the high will tend to drift away to the northwest, which leaves room for a cool northerly pattern over most areas. This will probably confine the best Tropo conditions to the southwestern half of the UK. Elsewhere, the main weather type will include summer showers, possibly heavy, and likely to be of interest for rain scatter activity. Showers in a cold northerly airmass are usually strictly diurnal, so rain scatter prospects are for the afternoon and early evenings. Sporadic-E is showing good signs of coming to life and we are starting to hear limited openings for traditional CW/SSB QSOs and more widespread activity for digital modes. Some promising multi-hop paths have been seen to Asia in the mornings and the States and the Caribbean in the evenings. This week contains potentially the most exciting meteor shower of the year. The Tau Herculids shower, associated with Comet 73P and discovered in 1930, appears early during Monday night into Tuesday morning. In 1995 the comet was seen to suddenly brighten. This was discovered as being due to its nucleus starting to break up, creating a debris cloud. Comet 73P orbits the Sun at 5.4-year intervals. The Earth next crosses its orbit on the night of the 30th of May, into the morning of the 31st. It is due to peak in the UK at about 0500UTC on the 31st. Depending on how the nucleus started to eject debris, we may have a spectacular shower or something that is, at best, disappointing. As it will be light in Europe during the peak the visual display may not be very impressive, but the possibility for a radio reflection shower must be strong. This is one to look for, as a meteor scatter enthusiast. The new Moon occurs on the 31st of May and illumination will be low all the following week. A maximum declination of +28.1 degrees occurs on the 2nd, and this also coincides with the greatest distance from Earth to Moon, which in turn means the highest path loss. From experience, this should still be a good week for EME on the microwave bands despite the path loss. The VHF EME bands will suffer noise from the proximity of the Moon to the Sun for the first few days of the week.

And that’s all from the propagation team this week.

Using the 5.7 and 10GHz bands, the exchange is signal report, serial number and locator.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 20th of May 2022. Solar activity reached a new peak for this cycle this week, with the solar flux index hitting 180 on Thursday the 19th. This was partly down to the very large active region 3014, which is almost big enough to be seen with the naked eye if suitable precautions are taken. To put this into perspective, the sunspot number is 147, which is higher than the estimated smoothed maximum prediction of 115 for Cycle 25. Meanwhile, geomagnetic conditions have been favourable with the Kp index moving between one and three since Monday. This is all good news and is being reflected in the band conditions at the moment, with round-the-world echoes being heard on some DX signals. Make the most of them as there is the ever-present threat of X-class solar flares to contend with. Two active regions, which have already been emitting X-class flares, are about to rotate into view. The USAF predicts that the SFI may stay above 175 until at least Wednesday, before declining into the sub-150 range. This is at odds with the NOAA prediction, which never really thought that the SFI would get to 180 last week. In other words, it is anyone’s guess what we will get! Don’t forget that Sporadic-E is also livening up the upper HF bands and providing strong short-skip signals. These can often link into multi-hop Es or join with F2-layer hops to give surprise long-distance DX that is hard to predict. We have never had it so good for some time and let’s hope it continues into the Autumn when HF can really come into its own.

And now the VHF and up propagation news. It seems we are in a typical summer unsettled pattern with areas of thundery rain and heavy showers drifting north from France. This will obviously keep rain scatter as an option. Summer can also be a time of strong Tropo, especially around coasts and over the adjacent seas. This is because a strong temperature inversion can develop over cool seas with areas of mist and fog at sea level overlain by warm dry air blowing off the continent. These paths are likely to persist over long periods, particularly across the North Sea, English Channel and Irish sea with extended options south across Biscay. To finish off we have the early stirrings of the 2022 Sporadic-E season, which is starting to show some promising signs, and not just on digital modes. A major controlling influence is often associated with the presence of jet streams nearby and the upper air forecast charts suggest that there should be some reasonable opportunities during the coming week. Don’t forget that jet stream upper air charts are available daily with commentary on the Propquest.co.uk website. There is no major meteor shower this week, but we are at the tail end of the Eta Aquarids shower, which began in late April and is generally regarded as petering out next weekend. Eta Aquarids are associated with Halley’s Comet. But don’t expect to see the comet until 2061! The Moon will be waning throughout this week with decreasing declination and increasing distance as it moves towards apogee and that, therefore, leads to increasing path loss. Moon libration will be low. This week’s TK/HB9CRQ Corsican EME microwave DXpedition should enjoy favourable lunar path conditions if the weather cooperates. And that’s all from the propagation team this week.

The news headlines: Innovation 70 project for Platinum Jubilee Youngsters On The Air contest IARU Monitoring Service newsletter

The RSGB has launched the Innovation 70 competition as part of its Platinum Jubilee activities. The challenge is to design and build a useful piece of equipment with no more than 70 connections, or a useful piece of software with no more than 70 lines of code. A selection of the most innovative entries will be published in RadCom and on the RSGB website. The RSGB Technical Forum will judge the entries and the results will be announced at the end of the year. The closing date is the 30th of September. Go to rsgb.org/jubilee and click on the Innovation 70 section to find out more. The next Youngsters On The Air Contest takes place on the 21st of May between 0800 and 1959UTC. Everyone can take part and show their support for young amateurs across the world. There are eight different categories, including special ones for those under 25 years of age. Using the 80, 40, 20, 15 and 10m bands, the contest is CW and SSB only. The exchange includes the age of the participating operators, which acts as multipliers. Find out more at ham-yota.com. The IARU Monitoring Service for Region 1 has published its April newsletter. It talks about emissions that are often received on the 40 and 20m bands with a bandwidth of about 8kHz. Thoughts are that it could be a jammer where the signal is intentionally transmitted over other transmissions in order to disrupt or nullify their reception. The newsletter includes a report by Richard, G4DYA, the RSGB Intruder Watch Coordinator, that includes many radar sightings. You can read more at iaru-r1.org. All RSGB Members who have an email address linked to their membership should have received an email in the last few days. This email explains how to set up a new password to access the updated membership portal. The email will have been sent to the email address linked to your membership account. If you are an RSGB Member and don’t think you have received an email, please do check your junk folder. If you still can’t see an email, please contact membership@rsgb.org.uk or call the RSGB during office hours on 01234 832 700 and choose option two. While the Society has been sending out the emails, access to the online members’ resources such as RadCom have been turned off, but it plans to make them accessible again early this week. Sad news now. Nancy Bone, G7UUR, the co-founder and long-time secretary of the Angel of the North ARC became a Silent Key last week. She was an RSGB Deputy Regional Manager for a number of years, a repeater licence holder, exam tutor and GB2RS newsreader. In everything that she did, she approached it with enthusiasm and commitment that challenged and inspired others. We are thinking of her husband Warren, G7MWB, their family and many friends at this difficult time. Since the AGM, the RSGB Board has made two appointments. Richard Horton, G4AOJ will be the new Board Chair and Stan Lee, G4XXI has taken on the role of Company Secretary. The Board would like to record its thanks to General Manager Steve Thomas, M1ACB for carrying out the additional role of Company Secretary since June 2020. Brickworks is a scheme run by local amateur radio clubs that have committed to helping all licensed amateur radio operators discover more about what the hobby has to offer. It was originally launched in early 2020 by the RSGB under the name of the Beyond Exams Club Scheme. When Covid struck, clubs were no longer able to meet in person and it was harder to help radio amateurs to work through the Club Scheme activities. Now life is opening up again, the RSGB is delighted that Brickworks, as it will now be called, is being relaunched. Whether you are a new licensee, returning to amateur radio or want to try something new, Brickworks has something to offer you. For more information see rsgb.org/brickworks.

And now for details of rallies and events Please send your rally and event news as soon as possible to radcom@rsgb.org.uk. We’ll publicise your event in RadCom, on GB2RS, and online. Next week the Dayton Hamvention takes place between the 20th and 22nd of May at the Greene County Fairground in Ohio, USA. Now in its 70th year, this is one of the largest amateur radio shows in the world, famous for its massive flea market. There will also be lectures, traders and a strong ARRL and RSGB presence, including a bookstall.

Note that UK stations also send their postcode.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 13th of May 2022. Well, it looks like the US Air Force was more accurate than NOAA with their solar flux index forecast last week. While the week started with an SFI at 117, by Thursday it had grown to 133. It has been mostly quiet from a geomagnetic point of view with a maximum Kp index of three, with mostly ones and twos. The only downside has been a number of solar flares, which includes an X-class flare on Tuesday the 10th. The X1.5 event was observed from sunspot region 3006 at 1355UTC and resulted in a radio blackout over the Atlantic, Africa and South America. The critical frequency, as measured by the Chilton Ionosonde, dropped below 7MHz for a time, before recovering. Despite this short-lived phenomenon, there has been plenty of DX to be worked on the higher bands. The 15m band has seen Asia and the Far East romping in on FT8 and there have been 10m band openings to Australia and the Middle East. Next week NOAA predicts that the SFI will be in the range 118-122 with generally quiet geomagnetic conditions. But we give the same warning as we did last week. NASA gives a 45% chance of an M-class flare and a 15% chance of an X-class flare occurring at the moment. Any solar flare could trigger a coronal mass ejection and, if Earth-facing, we can expect a degradation in HF paths, perhaps 36 to 48 hours after the CME event as the solar plasma hits and the Kp index rises. The better news is that the Sporadic-E season is now in full swing and plenty of low-power 10m beacons are becoming audible between 28.160 and 28.325MHz. These are often a good indicator of openings. A list of 10m beacons can be found on the RSGB website under On the Air. Just click on Beacons and Repeaters.

And now the VHF and up propagation news. There is a typical flavour to the current weather pattern with high pressure, initially to the south, being displaced east as an Atlantic low tries to push its associated weather fronts into western Britain. This will eventually lead to unstable, thundery bands of rain spreading into the country from the southwest. It makes detail complicated, but some rules still apply. There will be some Tropo, especially at first and perhaps occasionally next week along the east coast and across the North Sea. However, the changing element is going to be how effectively the thundery rain areas move across the country, and they will reduce the Tropo chances and introduce some rain scatter. There are some small meteor showers this week, the Eta Lyrids peaked on the 10th of May but the o-Cetids, peaking on the 20th of May, are the most significant. With this addition to the seasonal increase in random meteor flux, expect good conditions for meteor scatter DXing. Apart from the random meteor scatter options, the growing interest is in Sporadic-E and most days you can find something on the clusters to confirm that the new season is starting to simmer nicely. The position of jet streams and the type of upper-air weather pattern this week suggests that the main features will slow down and leave marked meanderings north and south. Preferred directions would be to Scandinavia and the Baltic plus secondly looking south towards Spain and Portugal. The Moon gets to minimum declination on Thursday, and today, Sunday is the perigee. The week’s trend will therefore be for shorter Moon windows until Thursday and rising path losses. 144MHz sky noise is high all week, reaching 2200K on Wednesday. And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 6th of May 2022.

Last week was characterised by solar flares. At the time of writing, we have seen more than 50 since the 1st of May, including one high-energy X-class flare. This occurred on the 3rd of May at 1325 hours and caused a radio blackout over much of the Atlantic. Luckily, the Kp index has remained low, which has enabled the ionosphere to develop. And solar flux indices have been steadily climbing and reached 130 by Thursday.

There have been many reports of good propagation. It has been a simple case of being in the right place at the right time. Ten metres has been open well into the evening at times, as well as providing paths to Australasia in the morning. At other times people have reported the band as being dead.

We have also seen the beginnings of the Sporadic-E season with reports that 10 metres has been wide open to Europe at times. Hopefully, this will develop as the month goes on.

Next week, NOAA predicts that the SFI may dip before climbing back into the 120s. However, the US Air Force says that it will just continue to rise, perhaps hitting 140. This seems more plausible going on past performance.

Geomagnetic conditions are predicted to be quiet with a Kp index of two. However, it would only take one Earth-facing coronal mass ejection to spoil this entirely.

And now the VHF and up propagation news.

Starting with Tropo news, this weekend sees the new week starting with high pressure right over the British Isles. This high will drift slowly southeast into the continent by midweek, centred over the Balkans. There should be some reasonable Tropo paths, especially to the south into France and northern Spain. This will be fairly short-lived because, starting midweek, a weakening cold front brings rain to northwest Britain and breaks up into showers as it moves south.

This brings the prospect of some rain scatter for a while and as per last week, this is likely to peak in the afternoon. After these showery days, another high appears by Friday to end the week, gradually transferring to the North Sea with a further chance of Tropo. Bear in mind that these weather forecasts are 10 days out so there are bound to be differences in the models. From midweek, some models retain the showery risk for longer.

Summer Sporadic-E, or Es, propagation is well underway with some early reports up to 2m by Chris, G0DWV who heard an IV3 briefly on 2m before dropping back into the noise. We have had many hints of the new season, mostly on 10m and 6m.

Just to remind you that Es activity tends to come in two periods, mid-morning and again late afternoon/early evening. Remember the daily blog onPropquest.co.uk, which gives the current day’s prospects as well as an EPI (Es Probability Index) map to allow you to plan your shack activity.

The Eta Aquariid meteor shower is tailing off now but the Make More Miles on the VHF website suggests that meteoroids released from the minor planet 2006GY2 may cause activity on the 15th of May around 1020UTC. Apparently, the stream should be dense, so worth a look.

The Moon has passed peak declination and we are a week away from next Sunday’s perigee. The week’s trend will therefore be for shorter Moon windows and peak elevation and falling path losses. 144MHz sky noise is low this week, slowly rising and reaching 400K next Sunday.

And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 29th of April 2022.

A week of high solar flux indices brought good openings on the higher bands. With the SFI consistently above 140 all week (at the time of writing) there have been reports of 10-metre openings well into the evening.

As Ian Goodier on the 10m UK Net Facebook group reported: “Tonight on 10m you could mistake the band for 20m - East Malaysia in one direction, Mexico in the other.”

There were also reports of Australian and New Zealand stations being worked on 10 metres, making this possibly one of the best weeks for 28MHz so far this solar cycle.

But there were some spanners in the works too. There were a lot of C-class solar flares and two M-class events this week. Geomagnetic conditions have also been disturbed at times with Wednesday being the worst day with the Kp index hitting five twice on one day. Solarham.net said this was an unexpected geomagnetic storm as the Bz component of the interplanetary magnetic field (IMF) tipped south. Another solar storm is forecast for the 29th of April, thanks to a large coronal hole on the Sun’s equator.

NOAA predicts more of the same next week with the SFI probably above 130.

Geomagnetic conditions are predicted to be quiet next week, with an average Kp index of two. That is, at least until the 7th of May when it could rise to four. However, this presupposes that we don’t have any coronal mass ejections to contend with. At this point in the solar cycle, solar flares and associated CMEs are commonplace and could push the Kp index higher roughly 48 hours after any Earth-directed CME. As always, keep an eye on Solarham.net for daily updates.

And finally, we can now expect a big upturn in Sporadic-E openings on the higher HF bands. Keep an eye on the European 10m beacons for openings and find out more in our VHF news.

And now the VHF and up propagation news.

As we move into May, the chances of Sporadic-E begin to increase and it's worth keeping a close eye on the usual bands from 10m up to 6m, later in the month, the 2m band might surprise us. The Propquest.co.uk website contains a useful EPI map plot of regions where Sporadic-E may be more likely based upon weather triggers of atmospheric gravity waves that are part of the formation process. It also contains a daily blog with commentary to highlight significant jet streams and other regions of interest.

The main focus on the weather charts starts with high pressure bringing fairly good Tropo conditions at the end of last week. Over this weekend a small low will drift into western areas and generally disrupt the Tropo propagation, producing a weaker pattern for next week with a hint of isolated showers. Later in the week, some models bring another low southeast from Iceland to Denmark introducing a cooler north-westerly flow with a few showers until a new high builds next weekend. The result of this will be possible Tropo windows later towards next weekend. There is a possibility of a little rain scatter in between, but generally limited.

The Eta Aquariid meteor shower will peak between midnight and dawn on Friday the 6th of May 2022. Its ZHR is a very respectable 50. The shower favours the Southern Hemisphere and the radiant is low in the sky for the UK in the early pre-dawn hours.

The predictable cycle of Moon-bounce propagation continues this week with positive Moon declination peaking on Thursday, now almost coinciding with apogee and therefore highest path losses. After mid-July, the trend of rising declination and rising path loss reverses, until, in mid-2026 maximum declination coincides with perigee and minimum path loss again. 144MHz sky noise is generally low this week, reaching 500K on Wednesday.

And that’s all from the propagation team this week.

GB2RS News

Sunday the 24th of April 2022

The news headlines:

• Two new GB2RS broadcasts
• Take part in SOS Radio Week
• VMARS nets

The RSGB GB2RS News Service is delighted to announce two new broadcasts on Sundays. With a nod to how it all started back in 1955, we have introduced a transmission using amplitude modulation. This takes place in the 80m band on 3650kHz at 8 am UK time from the station of G4JBD in Bedfordshire. The intended coverage is the Midlands and the South East of England but it may be heard more widely when propagation is favourable. For those in the South West Glasgow area who are busy on Sunday mornings, we are now offering an evening broadcast on 2m. Delivered by 2M0GUI on 145.525MHz FM, the transmission is at 6.30 pm UK time.

Every year thousands of people get into difficulty around our coast. Thousands of unpaid volunteers swing into action to save and rescue them. SOS Radio Week celebrates the work of these selfless volunteers. Amateur radio stations get on the air to raise awareness of the invaluable work of the Royal National Lifeboat Institution, National Coastwatch Institution and the many independent lifeboat and rescue organisations around our coasts. The activity starts at 0000UTC on the 1st of May and concludes at 2359UTC on the 31st. Participants are encouraged to become an official Registered Station and make as many contacts as possible, mentioning the reason for the event during their contact. For further details visit sosradioweek.org.uk

The Vintage Military Amateur Radio Society will be displaying at the Blackpool Rally today. They have regular nets on 3.615MHz at 8.30 am on Saturdays using AM and at 8 pm on Wednesdays using USB to facilitate the use of ex-military equipment. On Fridays, the frequency remains as 3.615MHz at 7.30 pm using LSB. More at www.vmars.org.

As part of the forthcoming Jubilee celebrations, the RSGB has announced further details of its GB70 special event station activities. The seven SES callsigns will be active across the Jubilee weekend, from the 2nd to the 5th of June, on multiple bands and modes by various clubs. After that weekend, these special callsigns will be available for activation by RSGB affiliated clubs or individual RSGB members until the 28th of June. Each callsign has a volunteer coordinator responsible for allocating operating slots in a published schedule. They will also collect the log files from those who have been activating the calls. For further information see the GB70 page in the RSGB Jubilee web section at rsgb.org/jubilee.

Provisional results for the 2021 IARU Region 1 Marconi Memorial VHF Contest are available. A total of 762 logs from 27 different countries in Region 1 were received. You can read the provisional results at iaru-r1.org.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 22nd of April 2022.

Last week was characterised by solar flares – lots of them! There were numerous strong flares, although the majority occurred in the early hours and so didn’t affect the ionosphere over Europe. Solar flare events can cause short-lived radio blackouts as the energetic photons penetrate deep into the D-layer. Solar activity during the past 30 days has increased drastically with five of the top 10 strongest flares of Cycle 25 detected during this period alone.

We have also had very strong sunspot activity with the solar flux index peaking at 160 on Thursday the 21st. The current crop of four sunspot groups probably means we can expect the SFI to stay high until at least early next week.

NOAA predicts the SFI will stay above 130, but we may get even higher figures for a time. It also predicts a maximum Kp index of two next week, although that could easily rise if we get hit by matter from any incoming CMEs, which are getting more prevalent as the cycle continues. The good news is that, at the time of writing, it didn’t look like we will get any coronal hole activity.

There have been numerous reports of good conditions on the higher bands - 21, 24 and 28MHz – including openings to TX5N on the Austral Islands. Braco, 8Q7DX, who is on holiday in the Maldives, has also been worked.

There have also been some signs of early Sporadic-E with very loud openings to Spain on 10 metres.

So if the SFI stays this high and we don’t get many geomagnetic disturbances it could be a good week for HF.

And now the VHF and up propagation news.

We have a classic spring start to things with low pressure over the near continent, aided by the increasing warmth of the spring sunshine, while colder regions to the north become home to high pressure near Iceland.

Between the two, we will have a strong and cold-feeling east to northeasterly wind over the UK; not really the setup required for Tropo, since the strong winds and turbulence destroy any temperature inversion.

The changes come along after this weekend as the low weakens and a ridge of high pressure extends south across the country with much lighter winds and a chance of Tropo, especially overnight.

It is possible that isolated showers may offer a little rain scatter, but not a high probability.

It would be better to consider possible aurora and meteor scatter as your exotic modes. In this closing part of April, the best is within reach, since Sporadic-E is a serious possibility on 10m and perhaps 6m. Use the beacons and clusters to guide you, but if you start to adjust to your summer operating rule of checking for Es mid-morning and late afternoon or early evening, then Es QSOs will soon come.

The Winter minimum of meteor show activity is at an end with Sporadic meteor rates increasing towards their usual maximum in late summer.

The Lyrids shower has passed the peak but continues to be active until the 30th.

Moon declination starts the week negative with low peak moon elevations and short visibility windows but turns positive again on Thursday. Path losses are on the increase again as we are past perigee. 144 MHz sky noise is low all week except Saturday afternoon when the Sun and Moon are close in the sky for the five hours leading up to Moonset at approximately 1900hrs.

And that’s all from the propagation team this week.

GB2RS News

Sunday the 17th of April 2022

The news headlines:

• RSGB AGM to be live-streamed
• Pop Up YOTA net today
• New EMF video

The RSGB AGM is being live-streamed on Saturday at 12 noon. You can still submit a question for the RSGB Board to answer during the event, but you will need to do so before 9 am on Wednesday the 20th of April. Voting in the elections closes at 9 am on Thursday the 21st of April. The Society encourages all RSGB Members to use their vote. Full details of the event can be found on the RSGB website at rsgb.org/agm.

A special Pop Up Youngsters On The Air net will be on the air today, Easter Sunday, at 1400UTC. This Pop-Up net is aimed exclusively at youngsters under the age of 25 and encourages them to call in and have a QSO with fellow youngsters on the air. The net controller for the first hour will be Declan, 2W0KYH who is aged 13. The 2nd hour is with Liam, M7LCB. The net is hosted by the FreeSTAR Amateur Radio network, which is a multi-node system where various digital radio modes are accessible including DMR, D-Star, Fusion C4FM and so on. For full connection details please visit freestar.network or email Oscar@freestar.network.

The RSGB has just released a short video outlining the new EMF regulations and the help and tools the Society provides for radio amateurs. There is a wealth of information and guidance on the RSGB website and the Society hopes that this video will signpost that in a new way. The video is in the ‘Did you know?’ playlist on the RSGB YouTube channel at youtube.com/theRSGB.

The IARU Region Political Relations Committee, in conjunction with the Region’s EMC Committee, has submitted a paper to a recent European Commission Call for Evidence with respect to Solar Energy Strategy. Solar energy systems, which include Solar PV, are a progressive technology whose use is to be encouraged. However, there are certain caveats to be noted in deployment and ongoing use. The IARU concerns are not with solar technology, but with the potential noise pollution from so-called optimisers. The paper that was submitted detailed elements of the ongoing research and monitoring by the EMC Committee in this area. The paper is available on the IARU Region 1 website at iaru-r1.org.

As part of the Commonwealth Games activities, RSGB Special Event Stations will be activated from the four UK Home Nations and three Crown Dependencies. The callsigns will take the format of GB22G followed by the Regional Locator, for example, GB22GE, GB22GI or GB22GD. RSGB affiliated clubs and individual RSGB Members who are Full licensees will be able to book slots to activate a callsign themselves or to supervise operation by others. Further details will be coming soon.

Radio Amateurs of Canada is supporting World Amateur Radio Day on the 18th of April by encouraging amateurs to get on the air and contact as many Canadian stations as possible. RAC official stations will operate across Canada from 0000Z to 2359UTC on the 18th. Look out for these special event stations with callsigns ending in RAC. Those contacting one or more of these stations will be eligible for a special commemorative certificate. Full details are on their website at rac.ca.

The RSGB will be running a special event station at the 2022 Commonwealth Games, starting on the 28th of July. The callsign will be GB22HQ. If you’d like to help operate the station during the Games and talk to visitors about amateur radio, please contact RSGB Region 5 Representative Neil Yorke, M0NKE at rr5@rsgb.org.uk. Due to the location of the station, operators will only be able to access the Games by train.

The RSGB and ARRL have been celebrating the centenary of the Transatlantic Tests. The Society has just released a video that highlights the fantastic exhibition put on by the National Heritage Centre in Saltcoats, the 1921 message re-enactment by the Kilmarnock and Loudoun Amateur Radio Club and also the 160m Transatlantic QSO Party. You’ll find the video on the RSGB YouTube channel at youtube.com/theRSGB

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 14th of April 2022.

We had a week with declining solar flux index numbers, but with the ever-present threat of coronal mass ejections. The SFI declined from 101 on Sunday to 96 on Wednesday with the possibility of further falls as the week goes on. A solar filament located near the centre disk of the Sun erupted early Monday morning generating a faint, halo coronal mass ejection (CME) that appeared to be squarely Earth-directed.

A moderate (G2) geomagnetic storm watch was added for the 14th and skywatchers at middle to high latitudes were also put on alert for aurora.

Meanwhile, the quieter geomagnetic conditions earlier in the week saw 10 metres open up to some good DX. Laurie, G3UML reports a long path opening to Australia on 20m CW from 0730 to 0800UTC. He worked two VK2s and a VK3 and listened to VK5QD who was very loud.

Next week NOAA predicts that the SFI may climb again, perhaps into the range of 100 to 110.

Geomagnetic conditions are predicted to be generally quiet, but with the ever-present risk of CMEs pushing the Kp index up to perhaps four or five at times. A pair of coronal holes became Earth facing on Thursday as well, which may bring unsettled conditions again this weekend. If the Kp index stays low we can expect MUFs to be near seasonal norms, perhaps with openings up to 21 and even 28MHz at times.

Look out for occasional early-season Sporadic-E openings as well, which could bring short-skip openings into Europe on 10 metres.

And now the VHF and up propagation news

The high pressure over the North Sea and Scandinavia will decline slowly allowing a new area of low pressure over the nearby Atlantic to drift east into southern Britain during the Easter weekend. This will mean that any Tropo benefits, particularly over the Irish Sea and the North Sea will decline during the weekend.

The new low will bring areas of showery rain across the country with a chance of rain scatter propagation. This is likely to be a pattern for much of the following week with low pressure over southern areas and occasionally expanding bands of rain farther north.

The solar activity has continued to provide aurora options, so again worthwhile checking the clusters and Kp index for early signs of auroral activity. It is also a given that random meteor scatter is always available, especially for those who like to be up early in the morning!

The main mode to keep a watch out for during the coming week is Sporadic-E, which is just beginning to make an appearance on 10m and even higher bands using digital modes.

Jet streams are important as potential sources of the atmospheric gravity waves that can contribute to Es. You should look to the jet stream 300hectopascal or hPa upper air charts to see where they are located. Try paths that cross them, especially where they cross mountain ranges like the Alps or Pyrenees. Note a hectopascal equals a millibar.

The Propquest.co.uk website has a set of four 300hPa charts for the current day and from the beginning of May will also contain a daily blog highlighting that day’s prospects.

The Winter minimum of meteor show activity is coming to an end. This week the small daytime April Piscids shower starts on the 20th, and peaks two days later at 2200UTC. This also coincides with the peak of the larger, and currently active Lyrids shower also on the 22nd but earlier at 1300 UTC. With a ZHR of around 18, it should produce some good reflections.

Moon perigee is on Tuesday so path losses are at their lowest. Moon declination is negative again and reaches minimum on Thursday so Moon windows will be short and peak Moon elevation low. 144MHz sky noise is high, peaking at over 3000K on Thursday so combined with the low elevations a poor week for especially VHF EME.

And that’s all from the propagation team this week.

The news headlines:

• Youngsters on the Air contest results
• Celebrate World Amateur Radio Day
• Use your vote in the RSGB elections

The final results of the third round of the Youngsters On The Air Contest in 2021 are now available. They can now be found on ham-yota.com/contest. Throughout the three legs of the contest, the organisers received nearly 700 logs from all over the world, including many from those under the age of 26. In 2022 the three sessions will be taking place on the 21st of May between 0800 and 1959UTC, then on the 23rd of July between 1000 and 2159UTC. The final round takes place in YOTA month, on the 30th of December between 1200 and 2359UTC.

On the 18th of April, radio amateurs worldwide take to the airwaves in celebration of World Amateur Radio Day. It was on this day in 1925 that the International Amateur Radio Union was formed in Paris. You can read more about the event and download posters and other publicity material for any special event station you may be planning, from iaru.org.

Just a reminder that voting is still open in the RSGB AGM. There are three resolutions to vote for including the endorsement of two Nominated Board Directors. They have been put forward by the RSGB Nominations Committee but it is RSGB Members who choose whether or not to endorse them. The Society encourages all members to read the CVs and personal statements of the Nominated Directors and then follow the voting links to cast a vote. On the RSGB AGM web pages, you can also see the RSGB Report and Accounts and submit a question for the RSGB Board to answer at the online AGM. Go to rsgb.org/agm to find all the information and links you need. Please use your vote.

The 2022 Commonwealth Games start on the 28th of July. Over 5,000 athletes will converge on Birmingham and the surrounding area from an estimated 72 hosts to compete over 12 days as part of the Games. The RSGB is organising a number of activities to support the event, including a special event station on the grounds of the National Exhibition Centre. The Society wants to showcase amateur radio to the athletes and public for as much of the Games as possible and will need a large number of volunteers to operate the station and chat with visitors. Due to the location of the station, operators will only be able to access the Games by train and participants will be security checked as part of the accreditation process. If you’d like to help operate the station during the Games, contact RSGB Region 5 Representative Neil Yorke, M0NKE: rr5@rsgb.org.uk.

We have received news via Charles, M0OXO from Gennady, UX5UO, the Ukrainian QSL Printer used by many. Gennady says that he is OK and still trading. You can see more at ux5uoqsl.com.

The 2nd of April 2022 marked the 40th anniversary of the Argentine invasion of the Falkland Islands. On that day in 1982, Bob, VP8LP, living at Goose Green, was hearing on a local VHF net that invading troops could be seen in the streets of Port Stanley. He was surprised to find that there was no mention of this by the BBC. Bob spoke to Laurie, G3UML in the BBC Ariel Radio Group radio room in the building next to Broadcasting House. This was probably the first confirmation of the invasion. Bob and Laurie have remained in touch ever since. On the 2nd of April this year, the two friends met up again on the air to relive their contact of 40 years previous, this time using the BBC centenary callsign GB100BBC. A feature about the original contact was broadcast on the 3rd of April during Radio 4’s ‘Broadcasting House’ programme. You can listen back to this via BBC Sounds. Laurie was also the guest presenter on last Tuesday’s RSGB webinar Tonight@8 in which he talked about his historic contact with VP8LP as well the recent reconstruction. You can watch the Tonight@8 presentation at rsgb.org/webinars.

Belgium's national society, the UBA, has joined other national Amateur Radio societies in banning amateurs from Russia and Belarus from their contests. See uba.be for full details.

Now the Special Event news

Final preparations for GB1BB are now underway at the Isle of Wight Radio Society. A crew of three young operators will, weather permitting, operate on 70cm through GB3IW; on 2m FM simplex; and on the 80m or 40m band using SSB. This Special Event Station is highly unusual in that it will be established on the Bramble Bank, a sand bar 3km north of Cowes, which is usually underwater. Twice a year, around the times of the Spring and Autumn equinoxes, extreme spring tides uncover the bank and a small island appears for about an hour. Look out for GB1BB around 6 am or 6 pm, on Easter Sunday, Easter Monday, or Tuesday the 19th of April. Activation will occur in only one of those time slots. G4ZUP/MM and G6RTE/MM may well be heard before and after the event. For the latest information and expected operating times, check iowrs.org.

Flight Refuelling ARS will be operating from the club station using GB2FRA to celebrate the club’s 40th anniversary. It is intended that the callsign will be used on all the bands and modes that are available from the club shack including 10GHz EME. Operations will run throughout April.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 8th of April 2022.

We had another week of high-ish solar flux numbers, but this time we had relatively settled geomagnetic conditions that really allowed the ionosphere to play ball for radio amateurs.

The week started well with the SFI above 140, which then declined as the week went on and was at 117 on Thursday. The maximum Kp index was four on Sunday and Monday, which then declined to one and two as the week went on, before going back to four on Thursday. It looks like the faint CME generated by a filament eruption on the 3rd of April did not reach Earth, which was a bonus.

A new report from NASA has confirmed that Solar Cycle 25 is racing ahead of the official forecast and the gap is growing. Sunspot counts have now exceeded predictions for 18 straight months. The monthly value at the end of March was more than twice the forecast and the highest in nearly seven years. The Solar Cycle Prediction Panel predicted that Solar Cycle 25 would peak in July 2025 as a relatively weak cycle, but instead, the cycle is shaping up to be stronger.

Conditions have been quite good with many reports coming in of DX on the HF bands. John, G4BAO reports that 10m has been rocking this week. There have been daily morning openings to Asia and Australia, plus South America and the Caribbean later in the day.

And Chris, G1WSA reports 20m QSOs with N3SJL and then VK7RG. The interesting part is that Chris was only using a short Diamond HF20FX 1.2m whip on a mag mount on his car.

Next week, NOAA’s prediction has the solar flux at 115 for most of the time, perhaps rising to 120 as the week progresses. A small Earth-facing coronal hole might spell unsettled geomagnetic conditions this weekend, and NOAA forecasts unsettled geomagnetic conditions for the 11th and 12th with a predicted Kp index of four.

So possibly more of the same next week - try to make the most of the good HF conditions.

And now the VHF and up propagation news.

Last week ended with a cold northerly wind, but with developing high pressure for the weekend a chance of some Tropo, although in cold and often dry air like this, it is rarely very effective.

As we move into the new week a slow-moving front drifts across the country from the Atlantic with some rain and perhaps a hint of rain scatter where the front breaks up into showery bursts of rain in southern Britain. The rest of the week will be largely controlled by slack ridges of high pressure, despite a temporary weak front reaching northwest Scotland for a time.

The weak ridging probably develops further into the Easter weekend with a region of high pressure over the country. Some models hold the new high farther south over France and may allow further fronts to edge into Scotland.

The usual bonuses of random meteor scatter and aurora are still in play given the right circumstances, as is the arrival of some early Sporadic-E as we move into the second half of April.

This could be aided by a very busy upper air pattern offering plenty of jet streams, which can be associated with Es formation regions. Check out 10m first and then 6m, especially for data modes.

Moon declination is at maximum this weekend and declining as the week goes on, so again, Moon windows are long and peak Moon elevation will be high. Apogee was last Thursday so path losses will decrease throughout the week. 144MHz sky noise is low all week, reaching a minimum of 174K on Monday.

And that’s all from the propagation team this week.

Sunday the 3rd of April 2022

The news headlines:

• Transatlantic tests and Paul Godley lecture
• Volunteers sought for the NRC
• MSF signals closed for maintenance

As most listeners will already know, Paul Godley was sent over from the USA 100 years ago to conduct the transatlantic tests. Those tests opened up the era of short-wave radio communication. But why Paul Godley? Who was he, why was he chosen and what happened next? On Thursday the 7th of April, all those questions will be answered in an open Zoom talk by Godley's grandson, Bruce Littlefield. The Zoom meeting will be hosted by Wigtownshire ARC in South West Scotland and will begin at 1900UTC. Everyone is invited, subject to a limit of 100, and joining details will be published closer to the meeting date at www.gm4riv.org.

The RSGB National Radio Centre welcomes thousands of people through its doors each month and introduces them to amateur radio. The Society needs to expand the team of volunteers and is particularly looking for people who can be part of the team each Thursday. If you are interested in becoming an NRC volunteer you should enjoy meeting people and be prepared to work a minimum of one, preferably two, days per month. Full training is given. Please email NRC Coordinator Martyn Baker, G0GMB for further information via nrc.support@rsgb.org.uk.

A scheduled annual maintenance shutdown of the MSF 60kHz Radio Time Signal service is planned. It will allow safe working on the masts and antennas. The service will be off-air from 0700 to 1700UTC each day between the 4th and 21st of April. The transmission will be restored overnight whenever possible. A radio-controlled clock will not be able to pick up the MSF signal during these periods, so may drift off from the correct time.

There have been recently a number of reports of individual holders of UK Amateur licences gaining Innovation and Trial licences from Ofcom. This is to conduct experimental transmissions on 40MHz or the 8m band. The RSGB has asked Ofcom for guidance concerning the status and possible contacts with such stations. Ofcom’s view is very clear. Any operation on 40MHz in the UK is not Amateur radio and therefore cross-band contacts to such stations by UK radio Amateurs operating on the bands licenced for amateur radio are not permitted. You can read the full statement from Ofcom in the RSGB Notices part of the RSGB website at rsgb.org.uk.

The RSGB is looking for a Convention Chair to lead the team of people who will create this year's Convention. If you understand the advantages of both online and in-person events and can contribute ideas for speakers and topics that will attract both audiences, this could be the role for you. For a full role description look on the volunteer vacancy page of the RSGB website at rsgb.org/volunteers.

BBC journalist and long-time RSGB Member Laurie Margolis, G3UML broke the fact of the invasion of the Falklands through amateur radio. On Monday the 4th of April, he will share how that happened in the RSGB’s free Tonight@8 webinar. He will also cover his involvement in the 1970 King Hussein story. Watch and ask questions live on the RSGB YouTube channel or special BATC stream. Find out more about this and the Society’s other webinars via rsgb.org/webinars

On the 18th of April, radio amateurs worldwide take to the airwaves in celebration of World Amateur Radio Day.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 1st of April 2022.

Last week we said there was a sense of excitement as it looked like the solar flux index would increase. But even NOAA didn’t predict that it would rise to 156, which it hit on Monday the 28th. Unfortunately, along with high sunspot numbers, we have had unsettled geomagnetic conditions. On Sunday and Monday last week, the Kp index hit four, due to the predicted coronal hole issues. By Thursday the 31st, the effects of an M4/M1 coronal mass ejection event from the 28th of March were being felt. This CME resulted from a pair of sunspots, which combined into one larger shock front.

The solar wind speed was above 500km/s and the Bz component of the interplanetary magnetic field shifted south meaning it coupled more easily with the Earth’s magnetic field, pushing the Kp index to five with warnings for middle to high latitude aurora happening.

If this wasn’t enough, we have had a number of solar flares to contend with, including an X1.3 event from active region AR 2975 peaking at 1737UTC on Wednesday the 30th of March. This will likely result in a CME coming our way.

All this has had numerous effects on HF, from fadeouts from the flares to pre-auroral enhancements from the CMEs and good conditions on 10 metres thanks to the high SFI.

A high f0F2 critical frequency has also meant that 40 metres has been open to inter-G signals at times.

We are now well and truly in a period where it is getting difficult to predict what will happen next. NOAA predicts that the SFI will remain above 120 for the next few days and then decline into the teens. We think the best advice is to keep an eye on solarham.net and watch out for news of CMEs leaving the Sun. Expect unsettled conditions around 48 hours after news of any CME.

But the best advice overall is just get on the bands and work DX whenever you can! We can often expect MUFs to exceed 28MHz at times so make the most of 10 metres when you can, for example, John, G4BAO reports 10m was wide open to Asia on Thursday morning.

And now the VHF and up propagation news.

Next week offers a change of wind direction from northerly to westerly with the glimmer of hope for high pressure after the weekend, but it's only a partial nod towards tropo with just a weak, temporary ridge extending across the southern UK from the Azores high.

The next items worth mentioning are as in last week’s bulletin; keep your ears and eyes open for aurora, after a promising end to the last week as we write this with fluttery signals on 80m, you should have sorted out some favourite beacons to listen out for. Also, the early mornings can be good for random meteor scatter activity.

As we roll over into April we are getting a bit closer to the 2022 Sporadic-E season. There have been some isolated examples on 10m CW/SSB and 6m on data modes, so it's time to start checking the position of jet streams and EPI on the Propquest.co.uk website.

The end of last week favoured paths to the south into Spain across a northwesterly jet stream over the Pyrenees and Cantabrian mountains, whereas next week it looks like paths to Scandinavia might be worth a look, although probably a lower probability for these more northern latitudes.

Moon declination is positive all week reaching maximum on Friday, so Moon windows and peak Moon elevation will be high. We are past perigee so path losses will increase throughout the week. 144MHz Sky noise is low all week, briefly hitting 500K on Thursday.

And that’s all from the propagation team this week.

The news headlines:

• Giles Read, G1MFG, Silent Key
• RSGB National Radio Centre re-opens
• Emergency comms in the Azores

We start with the sad news that the RadCom Technical Editor, Giles Read, G1MFG, has become a Silent Key following a short illness. Since June 2006 he has been an integral part of the RadCom and GB2RS team and will be missed by his colleagues as well as many in the wider amateur circle. An obituary is on the RSGB website at rsgb.org/sk. We will be adding to this web page and sharing a fuller tribute to Giles in the May edition of RadCom. Our thoughts are with his family and friends at this difficult time.

The RSGB is pleased to announce that the National Radio Centre at Bletchley Park will reopen on Monday the 28th of March. It will be open seven days per week as usual. The Society is sorry to have had to close the NRC last week due to a significant number of volunteers suffering from Covid and is grateful for your support of that decision. If you had hoped to visit last week, the RSGB is sorry for any disappointment caused and the volunteers look forward to welcoming you soon.

The island of São Jorge in the Azores has suffered over 1800 earthquakes in 48 hours. The Regional Government has prepared contingency plans to protect the island’s population. CT1END, the Emergency Communications Co-Ordinator for Portugal, reports that a group of nine radio amateurs are working to support emergency communications locally and back to Portugal. Radio amateurs are asked to steer clear of 3.75 to 3.76MHz overnight, 7.1 to 7.11MHz during the day and around 14.300MHz for those amateurs outside the region. All radio amateurs are encouraged to listen carefully and avoid causing any interference to emergency operations on those frequencies. More at iaru-r1.org.

A brief reminder now. In the UK the clocks went forward 1 hour at 1 am this morning, the 27th of March.

Voting in the RSGB 2022 AGM is now open. There are three resolutions to vote for including the endorsement of two Nominated Board Directors. They have been put forward by the RSGB Nominations Committee but it is RSGB Members who choose whether or not to endorse them. The Society encourages all members to read the CVs and personal statements of the Nominated Directors and then follow the voting links to cast a vote. On the RSGB AGM web pages, you can also see the draft accounts and submit a question for the RSGB Board to answer at the online AGM. Go to rsgb.org/agm to find all the information and links you need.

Next Sunday sees the Spring 70MHz contest run from 0900 to 1200UTC. Using all modes, the exchange is signal report, serial number and locator.

Now the radio propagation report was compiled by G0KYA, G3YLA, and G4BAO on Friday 25th of March 2022.

We had a good week of HF propagation with moderate solar flux index numbers and generally quiet geomagnetic conditions. The KP index has not been above three, at least by Thursday when this was written. The SFI has been hovering around the 100 mark, which was enough to stir 12 metres into action with occasional 10m openings.

A proton storm was detected earlier in the week, courtesy of the LASCO instrument on the SOHO spacecraft. This was as a result of a CME on the far side of the Sun, which was luckily not Earth-directed.

We now have a sense of excitement as a new sunspot group is currently turning into an Earth-facing position. Active region 2975, along with a larger Earth-sized sunspot group, appears to be in a growth phase. Both regions will likely be a threat for at least minor C-Class or moderate M-class solar flares over the next week.

NOAA predicts the SFI may rise from 98 to perhaps 120 over the next seven days. Geomagnetic conditions are forecast to be unsettled around April 1st with a predicted Kp index of five. A coronal hole became Earth-facing on Thursday so there is also the chance of an elevated KP index and reduced MUFs over the weekend.

Finally, with the spring equinox here this is a good time for North-South paths on HF. Higher-band contacts into South Africa and South America have been prevalent over the last week and should continue for a few weeks.

And now the VHF and up propagation news.

Through much of the coming week, we will see the high-pressure system dominating the weather charts and continuing to provide a chance of further Tropo paths on VHF and UHF.

In this case, the high pressure will, at times, be centred right over the country and when this happens the temperature inversion may be too close to the ground for longer distance Tropo since it is changes in the refractive index of the air across the inversion that makes Tropo work for RF waves.

To avoid problems near the high centre, it is usually better to look for paths around the side of a big high to get the best DX. There are some weather models that try to break down the high later in the week, so make the most of the better conditions when you can.

There are still signs of disturbed solar conditions, so there’s always a chance of some aurora to play with, or of course, any random meteors may be worth a check, especially early morning.

There are reports of some strong Sporadic-E signals on 10m, so as we move into April it becomes a more regular item on the menu, say for 10m and perhaps 6m on digital modes.

Moon declination is increasing and goes positive again on Friday, so Moon windows and peak Moon elevation will increase. With perigee last Wednesday, path losses are low but increase as the week progresses.

144MHz Sky noise is low all week.

And that’s all from the propagation team this week.

CQ Amateur Radio magazine has said it will not accept competitive entries in any of its sponsored contests by amateur radio stations in Russia, Belarus or the separatist Donbas region of the Ukraine. Future events will be considered on a case-by-case basis, depending on the situation at that time.

Now the radio propagation report, was compiled by G0KYA, G3YLA, and G4BAO on Friday the 18th of March 2022.

Well, what a mixed week of solar activity we have just had. Last week, we forecast that we could expect unsettled geomagnetic conditions over the last weekend but we didn’t expect to see the Kp index hit six.

Sunday the 13th saw ground-based magnetometers hit hard with at least 15 hours of unsettled conditions when the Kp index fluctuated between five and six. This was caused by a full halo coronal mass ejection or CME, that was observed coming off the Sun on Thursday the 10th. This had a strongly negative Bz component so more easily coupled with the Earth’s magnetic field.

The net result was a decline in MUFs, reports of visible aurora in Scotland and complaints about HF conditions with the ensuing G2 geomagnetic storm.

Saturday wasn’t too bad with lots of contacts being made during the early part of the Commonwealth Contest. Twenty-metre contacts with the New Zealand ZL6HQ station were also possible from the UK, although signals were very fluttery. The short path to ZL goes through the North pole auroral zone so it is not surprising that the signals were affected, despite the Kp index being down to one, from five, during the late morning.

The solar flux index held firm at 125 on Saturday but was already declining and was down to 107 by Thursday.

So, after last weekend’s onslaught, what do we have in store for next week?

NOAA’s Space Weather Prediction Centre thinks that the solar flux will again decline, from a predicted 115 on Saturday down to 95 on Friday the 25th. The geomagnetic conditions prediction has the Kp index rising to four on Sunday but it may then decline to two by Wednesday the 23rd. The risk of an Earth-facing coronal mass ejection seems to have declined with the decrease in solar activity. So, for once, it looks like a good thing!

And now the VHF and up propagation news.

High pressure will dominate the weather charts over the next week or more, centred a long way east over Poland and the Baltic but with a strong ridge extending west towards the British Isles.

These large highs are usually associated with a marked temperature inversion and this is a good omen for extensive tropo. This works best if there is moisture below the inversion, so misty low cloud or fog will be a good indicator for better conditions.

When the forecast is for dry sunny weather, this usually means that the Tropo may not be so reliable. Paths across the North Sea to northern Europe and into the Baltic region are worth extra attention.

It’s a good time to get together a list of beacons from the region, either from the RSGB website or www.beaconspot.uk and check the various clusters for signs of activity.

We are nearly there for the Sporadic-E season, but not quite yet. Aurora and meteor scatter are still worth a look though.

The Moon will be waning throughout this week with the lowest declination on Friday/Saturday. However, the path loss is also at a minimum this week, so conditions should be good until the 23rd when the Moon moves into the noisier part of the sky, for several days.

The early part of the week should provide opportunities for stations with fixed or limited elevation adjustment, due to the low elevation of the moon.

And that’s all from the propagation team this week.

Now the contest news

When operating in any contest, please keep yourself and fellow amateurs safe by following all relevant pandemic-related government rules. For RSGB Contests, until further notice, all logs received from stations located in the Russian Federation or Belarus will be treated as check logs.

The second 70MHz Cumulative Contest takes place from 1000 to 1200UTC today, the 13th. Using all modes, the exchange is signal report, serial number and locator.

The RSGB Commonwealth Contest ends its 24-hour run at 1000UTC today, the 13th. This is one of the longest-running contests in the HF contesting world. It is CW only on the 3.5 to 28MHz contest bands. The exchange is signal report and serial number.

The 1.3GHz UK Activity Contest takes place on Tuesday from 2000 to 2230UTC. Using all modes, the exchange is signal report, serial number and locator.

On Wednesday the CW leg of the 80m Club Championships takes place between 2000 and 2130 UTC. The exchange is signal report and serial number.

Also on Wednesday, the 1296MHz FT8 Activity Contest runs between 1700 and 2100 UTC. The exchange is callsign and your 4-character Maidenhead locator.

Thursday sees the all-mode 70MHz UK Activity Contest take place between 2000 and 2230UTC. The exchange is signal report, serial number and locator.

Next weekend the BARTG HF RTTY Contest takes place from 0200UTC on the 19th to 0159UTC on the 21st. Using the 80, 40, 20, 15 and 10m bands where contests are permitted, the exchange is serial number and time in UTC.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Friday the 11th of March 2022.

We may not have had a large number of sunspots this week, but at least the Sun was consistent. We started the week last Sunday with a sunspot number of 116, and by Thursday it was still at 115. This sounds worse than it actually was as there were six sunspot groups active on Thursday, including newly-assigned active region 2965, which is coming into view off the east limb.

As we predicted, last weekend was characterised by unsettled geomagnetic conditions with a maximum Kp index of five across Saturday and Sunday. This affected HF a little, but there were still some good UK scores put in for the ARRL DX International SSB contest, with Andy, M0NKR making 812 contacts in just seven hours on 40, 20 and 15 metres. He also reports working many USA west coast stations on 15 metres, which appeared to be the money band.

NOAA predicts that next week we will have a decline in solar activity with a predicted solar flux index of 110 falling to 100 by the end of the week. From a geomagnetic point of view, it may be a repeat of last weekend. NOAA says that it predicts a maximum Kp index of four this weekend, then we may have quieter conditions next week. But then it predicts an elevated Kp index the following weekend (19th to the 21st) of up to four again.

Finally, don’t forget we have the Commonwealth Contest this weekend, which is a great opportunity to work some choice DX stations with no competition from non-Commonwealth entities - this doesn’t happen very often!

And now the VHF and up propagation news.

This first weekend sees a continuation of the unsettled weather type, especially in western areas, but there is a large area of high pressure just out of reach over central Europe. This looks as though it could edge towards the eastern side of the UK as we move into the new week and may give some Tropo to the east into the Baltic regions.

The problem is that there is a chance of some, much colder, air moving in from the east with a chance of some wintry showers. Although the main feature is likely to be the strength of the winds, bitter cold is not really conducive to good Tropo.

The other modes can still play a role, so check the solar data for high K indices, indicating a chance of aurora, as well as the usual early morning random meteor scatter. Perhaps start to dust down your techniques for Sporadic-E as we head into the second half of the month. We are not there yet, but maybe it is worth the occasional look at 10m.

The Moon’s declination is positive until next Saturday, and path losses are falling with perigee still more than a week away. 144MHz sky noise is low all week, creeping to just over 300 Kelvin next weekend.

And that’s all from the propagation team this week.

GB2RS News

Sunday the 6th of March 2022

The news headlines:

• RSGB statement the Russian Federation and Belarus
• RSGB AGM online
• QO-100 Emergency comms exercise

The normal stance of amateur radio is that it is apolitical. However, it is clear that recent actions by the Russian Federation and their military have crossed a line and the RSGB cannot in this instance remain neutral. The policy of the RSGB is that we will follow the actions of the mainstream sporting bodies with regard to all activities of a competitive nature such as contests and ARDF. Russian and Belarusian radio amateurs are therefore currently ineligible to participate in any event that is organised/sponsored by the RSGB. The policy of the RSGB in commercial activities is that we will refrain from trade with Russia and Belarus until further notice.

The RSGB Annual General Meeting on Saturday the 23rd of April will, once again, be held online. Members will be able to submit questions in advance for RSGB Board Directors to answer. We will announce the recipients of the RSGB annual awards and trophies as well as the winners of the Construction Competition. The RSGB President will give his review of 2021 and there will be an excellent presentation after the formal business of the day. Full details will be available in the April edition of RadCom and on the website from the 16th of March.

On the 26th of February, 22 stations representing 14 countries around IARU Region 1 took part in a short notice exercise using the facilities of the geostationary satellite QO-100. This was the first of a number of smaller exercises, tests and meetings to be held by IARU Region 1 throughout the year, building on the earlier Global Simulated Emergency Tests to cover as many aspects of emergency communications as possible. The intention is to bring emergency communicators together more frequently to demonstrate how the Amateur Radio Service can work together as a global community and develop a common understanding of each other’s capabilities. More information at IARU-r1.org.

The RSGB has agreed to fund a 50MHz beacon specifically to study meteor events above the UK. Unlike conventional propagation beacons, this will beam vertically up using circular polarisation. The 50MHz band is particularly suitable for observing meteors by radio as they create an ionised trail strongly reflective to radio at that frequency while they burn upon entry to the Earth’s atmosphere. This is a collaborative project between the amateur radio and radio astronomy communities and will enable a range of radio-based citizen science and STEM projects studying meteors. The beacon is to be located at the Sherwood observatory of the Mansfield and Sutton Astronomical Society, a central location for UK coverage.

Radio amateurs in Ukraine appear to be diligently maintaining radio silence as the state of emergency declared there just prior to the Russian military invasion remains in effect. A Presidential decree on the 24th of February included “a ban on the operation of amateur radio transmitters for personal and collective use”. The Ukraine Amateur Radio League reported this past week that it has received many messages of encouragement from the worldwide amateur radio community.

An updated document, detailing New Zealand amateur radio beacons including their active status, is now available online. This includes those beacons on the HF bands. Go to nzart.org.nz and scroll down for the news item on ZL beacons.
