KFAX
KFAX (1100 kHz) is a commercial AM radio station licensed to San Francisco, California and heard around the Bay Area. , the station is owned by Salem Media Group and programs a Christian radio teaching and talk format.
The studios and offices are on Liberty Street in Fremont and the transmitter is Hayward near the San Mateo–Hayward Bridge. KFAX broadcasts at 50,000 watts, the highest power permitted for AM stations. But because 1100 AM is a clear channel frequency reserved for Class A WTAM in Cleveland, KFAX must use a directional antenna to avoid interference, aiming most of its signal away from the east.
