KUSF began in 1963 as a campus-only AM station managed by the Associated Students of the University of San Francisco (ASUSF).
[4] USF accepted the offer and on April 25, 1977, KUSF became an FM station broadcasting on the 90.3 frequency; the call letters had been changed over shortly after the university became the licensee, on August 20, 1973.
In its early days KUSF was a conventional college station, broadcasting programs of interest to the university and greater San Francisco community.
[citation needed] For many years the programming, which was largely automated after 1976, was simulcast on KIBE 1220 AM, a 5 kW AM station in Palo Alto, California that began broadcasting in 1949 from a transmitter near the western approach to the Dumbarton Bridge.
[citation needed] On January 18, 2007, Bonneville signed an agreement with Entercom Communications Corporation to trade three San Francisco stations — KOIT, KMAX-FM, and KDFC — for three Entercom stations in Seattle, Washington and four in Cincinnati, Ohio.
It also announced the purchase of the intellectual property and call letters of KDFC from Entercom, moving its programming to those two stations and making it a listener-supported non-commercial outlet with Lueth as its President.
[3] The Federal Communications Commission officially transferred the 90.3 MHz license to the University of Southern California on June 7, 2012.
Programming features include: Mozart In the Morning, the Island of Sanity, and San Francisco Symphony broadcasts.
On-air personalities include Rik Malone, Dianne Nicolini, Robin Pressman, Hoyt Smith, Rich Capparela, Lara Downes and Jennifer Miller.
