KPFK (90.7 FM) is a listener-sponsored radio station based in North Hollywood, California, United States, which serves the Southern California, and also streams 24 hours a day via the Internet. It was the second of five stations in the non-commercial, listener-sponsored Pacifica Foundation network.
KPFK 90.7 FM began broadcasting in April 1959, twelve years after the Pacifica Foundation was created by pacifist Lewis Hill, and ten years after the network's flagship station, KPFA, was founded in Berkeley. KPFK also broadcasts on KPFK-FM1 along the Malibu coast, K258BS (99.5 MHz) in China Lake, California, K254AH (98.7 MHz) in Santa Barbara, California.
With its 110,000- watt main transmitter atop Mount Wilson, KPFK is one of the most powerful FM stations in the western United States. The station can be heard from the California/Mexico border to Santa Barbara to Ridgecrest/China Lake. A second 10- watt translator is licensed in Isla Vista, California, a census-designated place outside of Santa Barbara. The transmitter for that station is located atop Gibraltar Peak, allowing its broadcast to be heard over a large portion of southern Santa Barbara County.
