KFMB (760 kHz, "TalkRadio 760") is an AM talk radio station in San Diego, California, United States. It is owned by Midwest Television, Inc., along with KFMB-FM (100.7 FM) and KFMB-TV (channel 8). All three share studios in the Kearny Mesa district of San Diego. KFMB is one of the few stations in the U.S. that significantly increases power at night. The daytime power of 5,000 watts is limited due to proximity to KBRT (740 AM), a religious radio station with its transmitter in Orange County. The nighttime power is 50,000 watts, with a signal pattern that follows the California coast. KFMB's antennas are unique in that they are located on both sides of a highway (Route 52 in Santee, California).
KFMB first greeted listeners on August 19, 1941, broadcasting from the corner of Pacific Highway and Ash Street, downtown. Owned by Warren B. Worcester and the Worcester Broadcasting Corporation, the "M" in KFMB was for Worcester's daughter Mary; the "B" for his son Warren Burnham. The FCC construction permit was for 1420 kHz. By the time the station signed on all stations on 1420 kHz had moved to 1450 kHz as a result of the North American Regional Broadcasting Agreement. KFMB changed frequencies several more times, to 550 AM in 1948, 540 AM in 1954 and finally, in 1965 to its current position at 760 AM after a realignment of broadcast channels between the United States and Mexico.
