Portland Radio Authority (PraRadio) was a listener supported pirate radio station originally broadcasting from a mobile, 100-watt transmitter in Portland, Oregon. Listeners and musicians were encouraged to send tracks to the station, with or without a recording contract, and PraRadio would add the music to its mix. The station operated illegally from May 2002 until March 2006, when the U.S. Federal Communications Commission ended the transmissions.
