Many thanks to SRAA contributor, Andy Robins, who shares the following recording and notes:

This is a recording of U.S. pirate radio station "Jolly Roger Radio" from my location in Kalamazoo, Michigan, beginning at 2300 UTC on 9 November 1980. At that time I was using a Collins R390A receiver and a random-length, end-fed wire antenna. The station was about the only U.S. pirate at that time that specialized in Bluegrass, folk, and Americana music. This was part of a marathon, multi-hour broadcast that led directly to the FCC "busting" the station and putting it off the air. It was revealed that Jolly Roger Radio operated from Bloomington, Indiana, with a transmitter power of around 50 watts.
