KPFK is a listener-sponsored radio station based in Los Angeles. KPFK was the second of five stations in the non-commercial Pacifica Foundation network. The Pacifica Foundation was founded in the late 1940s out of the peace movement surrounding World War II, becoming the birthplace of a listener-sponsored radio. KPFK has been broadcasting since 1959 over 110,000 - Watts, the strongest signal west of the Mississippi. KPFK continues to produce the majority of programs in-house giving it the flexibility to provide a platform for stories, news, music, and information to serve the cultural welfare of the communities in and around Southern California that you will not hear anywhere else. KPFK believes forging social change is a fundamental part of how radio can make a positive impact on communities.
