KNBR

KNBR, The Sports Leader, is the on-air branding used by two AM radio stations in the San Francisco, California, area broadcasting a sports radio format, owned by Cumulus Media.

The main station, KNBR (680 kHz), licensed to San Francisco, broadcasts on a clear channel from transmitting facilities in Belmont, California. KNBR's non-directional 50 kilowatt (or 50,000 watt) signal can be heard throughout much of the western United States and as far west as the Hawaiian Islands at night. Because of its extensive range, it is sometimes called by the nicknames "The 50,000 Watt Flamethrower", "The Blowtorch", and "The Mighty 680". Prior to adopting a sports format, KNBR enjoyed a long history as the flagship of NBC's West Coast radio operations.

A second station also uses the KNBR brand. KTCT (1050 kHz) is licensed to San Mateo, California, with a transmitter located in Hayward, California. KTCT carries a separate sports format known as "The Ticket". The KNBR re-branding took place in 2003.

Between the two stations, games of the San Francisco Giants, San Francisco 49ers, Golden State Warriors, Stanford Cardinal, and San Jose SaberCats are broadcast to the San Francisco Bay Area.
