KSFO (560 kHz) is a commercial AM radio station in San Francisco, California. It is owned by Cumulus Media and airs a talk radio format. The station's studios and offices are on Battery Street in the SoMa district of San Francisco, along with five other Bay Area Cumulus stations. KSFO is powered at 5,000 watts. When radio waves travel further at night, KSFO switches to a directional antenna using a two-tower array, to protect other stations on 560 AM. The transmitter is on Amador Road in Brisbane, California, near the Islais Creek Channel.
