It’s a wireless military broadcast station that once sent coded messages and secret instructions to ships out at sea. Later, it became a prison where suspected communists in the navy were held In recent years, people have started to appreciate the station’s historic value.

He’s with us on the line today for a look at the station’s secretive past and the uphill battle he’s fought to keep the site in good shape.
