Jeff Welton is a sought-after speaker at broadcast engineering conferences. As a regional sales director at Nautel, he visits hundreds of radio transmitter sites, noting areas for improvement prior to installing a new transmitter - or for providing a better operating environment for an existing transmitter. We talk with Jeff about troubleshooting techniques for today’s solid state transmitters. What about air handling now as opposed to older tube transmitter air cooling? And how is efficiency and reliability better or different now? Chris Tarr adds updated advice from his own hands-on work with a variety of transmitters, including several brands of solid state units.
