Switching back to the KGO-FM call sign, the FM signal complemented the primarily local talk programming of its AM sister station.ĪBC sold the station on January 1, 1984, to Weaver, Davis, Fowler (WDF), which owned KLOK in San Jose accordingly, the station was renamed KLOK-FM. This lasted until May 1982, when stiff competition from KMEL and CBS-owned KRQR prompted KSFX to drop AOR for talk, featuring the ABC-syndicated Talkradio network. In late 1980, KSFX switched to an album-oriented rock (AOR) format modeled after sister station KLOS in Los Angeles. During the late 1970s, KSFX had a brief run with a disco format. By late 1974, the station veered towards a dance/soul-flavored format. At that time, KSFX aired a top 40 'Musicradio' approach, similar to WABC in New York City. KGO-FM changed its call sign to KSFX in early 1971, keeping its progressive rock format until May 1973. By the late 1960s, as the Federal Communications Commission (FCC) began requiring FM stations to offer separate programming from that of their AM counterparts, KGO-FM, like other ABC-owned FM stations, was an outlet for Love, an automated progressive rock format. In earlier days, it simulcast its sister station, KGO (810 AM), occasionally airing a stereo version of The Lawrence Welk Show. The former ABC Radio-owned station started on Novemas KGO-FM. KOSF broadcasts in HD Radio with two digital subchannels. The KOSF studios are located in San Francisco's SoMa district, while the station transmitter is based atop San Bruno Mountain near Daly City.
