I think a lot of pirate stations showing up on the dial are run by a lot of former radio pros. The reason I come to that conclusion is there is a fellow who claims to have worked in radio professionally and runs an undocumented signal about 15 miles from me in northern MN called "Liquid Radio". The only thing that makes them stick out is the music they play, which 99% of the time leans toward EDM. Otherwise with the audio processing, IDs and other production, no one would know the difference.
