KFMB (760 kHz, "TalkRadio 760") is an AM talk radio station in San Diego, California, USA. 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 5000 watts is limited due to proximity to KBRT ( 740 AM), a religious radio station with its transmitter in Orange County, California. 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).
