KUSF was a non-commercial radio station licensed to San Francisco, California and owned by the University of San Francisco. From 1963 until 2011, the station broadcast at 90.3 FM MHz. KUSF currently broadcasts online and is still a student driven organization at the University of San Francisco.
On January 18, 2011, the station’s longtime student-run, freeform/eclectic music format was abruptly dropped from the 90.3 FM frequency following the announcement of the station’s sale. That same day, the University of Southern California announced a deal with Entercom Communications to acquire the call sign, programming and intellectual property of longtime classical music outlet KDFC-FM, and began airing the station’s programming on the 90.3 FM frequency (as well as on also-acquired KNDL) later that same day.
USF will keep the KUSF call letters (for branding purposes) and intellectual property and continue it as an online-only station.
