KNBR (680 kHz) is an AM radio station in San Francisco, California, broadcasting on a clear channel from transmitting facilities in Redwood City, California. KNBR's non-directional 50,000-watt class-A signal can be heard throughout much of the western United States and as far west as the Hawaiian Islands at night. For several decades, KNBR enjoyed a long history as the flagship station of NBC's West Coast radio operations.
Two other stations also use the KNBR brand. KNBR-FM (104.5 FM) in San Francisco has been a full-time simulcast of KNBR's programming since September 6, 2019. KTCT (1050 kHz) is licensed to San Mateo, California, with a transmitter located near Hayward, California. It carried a separate sports format known as The Ticket but was rebranded as a second KNBR in 2003. The Sports Leader is the on-air branding used by all three stations. KNBR maintains its studios on Battery Street in San Francisco in San Francisco's Financial District.[2]
Between the three stations, games of the San Francisco Giants, San Francisco 49ers, Bay Area Panthers and Stanford Cardinal are broadcast to the San Francisco Bay Area. KTCT was available in the HD format on 1050 kHz but has been broadcasting in analog.[3] In addition, KNBR was simulcast on the HD2 subchannel of KSAN in nearby San Mateo.
