KTCT
KTCT (1050 AM) is a commercial radio station licensed to San Mateo, California, and serving the San Francisco Bay Area. It is owned by Cumulus Media and airs a sports radio format as KNBR 1050, a sister station to KNBR and KNBR-FM.

By day, KTCT is powered at 50,000 watts, the maximum for commercial AM stations in the U.S. But because 1050 AM is a clear channel frequency reserved for Class A XEG Monterrey, KTCT reduces power at sunset to 10,000 watts. It uses a directional antenna at all times with a five-tower array. The transmitter is off West Winton Avenue in Hayward, near San Francisco Bay.
