KGB (AM)

KGB (760 kHz) is a commercial AM radio station licensed to San Diego, California. It is owned by iHeartMedia and airs a sports radio format. Most of the evening and weekend programming comes from Fox Sports Radio, along with San Diego Gulls hockey, San Diego State University football and basketball, and Los Angeles Lakers basketball. Local sports shows are heard weekday mornings and afternoons.

The station first broadcast in 1941 as KFMB, founded by aerospace engineer Warren Burnham Worcester broadcasting mostly classical music. In 1943, Jack O. Gross bought KFMB radio and would later create sister television station KFMB-TV and FM station KFMB-FM; the trio of stations were owned by Chicago-based Midwest Television from 1964 to 2017. For much of the 1960s and 1970s, KFMB AM had a full service format combining news, MOR music, and sports. KFMB AM was one of the most popular radio stations in San Diego from the mid-1970s to late 1980s as the station shifted away from music to emphasize talk shows. As a talk station, KFMB AM had such hosts as Ted Leitner, Hank Bauer, Rick Roberts, and Roger Hedgecock and had a focus on conservative talk shows.

In 2017, Tegna Inc. bought the KFMB radio and TV stations from Midwest Television, then sold the KFMB radio stations to Local Media San Diego in 2019. Less than a year later, iHeartMedia bought KFMB AM and changed its call sign to KGB. In 2022, iHeartMedia changed KGB's format from talk to sports and moved much of KGB's talk programming to sister stations KOGO and KLSD.

By day, KGB transmits 5,000 watts, using a non-directional antenna, but at night, power increases to 50,000 watts, the maximum for AM stations in the U.S. A directional antenna with a three-tower array is used to minimize interference after dark with WJR Detroit, the Class A station on 760 AM, a clear channel frequency. The transmitter is in Santee, along the San Clemente Canyon Freeway.
