What is "kosc"

KOSC (90.3 FM) is a non-commercial radio station in the San Francisco Bay Area. The station broadcasts a classical music format, repeated on 89.9 FM in Angwin, California. That station is currently assigned the KDFC call sign. The two stations are both branded as "KDFC", and are owned by the University of Southern California, via its Classical Public Radio Network. KDFC is the radio home of the San Francisco Symphony and the San Francisco Opera. Programming originates from San Francisco.

KDFC programming also airs on translator signals in Eureka and Lakeport.

While the University of Southern California officially has owned KDFC in Angwin and the two translators, the University of San Francisco owned KUSF's frequency, though it was operated and programmed by USC, until June 7, 2012 when the Federal Communications Commission officially transferred the license to new owner USC, operating as the Classical Public Radio Network.
