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).
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 Radio 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.
Warren Worcester died on October 24, 1942, following a brief illness. In November 1943 the trustees of Worcester's estate sold KFMB to its general manager, Jack O. Gross and a business partner, O.L. Taylor; Gross purchased Taylor's 50 percent interest and became sole owner in 1945. Under Gross's stewardship KFMB pioneered FM and television service in San Diego, launching KFMB-FM in April 1947 and KFMB-TV in May 1949.
In November 1950, Gross sold the KFMB stations to John A. Kennedy, a former publisher of the San Diego Daily Journal. Three years later, Kennedy sold the trio to a partnership of television producer Jack Wrather and industry executive Helen Alvarez. In 1957 Alvarez sold her shares in KFMB to Wrather, who then sold his broadcast interests to Buffalo, New York-based Transcontinent Television Corporation in early 1959. As part of Transcontinent's exit from broadcasting, KFMB-AM-FM-TV was sold in 1964 to current owner Midwest Television, then based in Champaign, Illinois.
In the mid 1970s, KFMB's format was an adult-oriented Top 40, and featured such personalities as Perry Allen, the morning drive teams of Charlie and Herrigan (Jack Woods and Paul Menard) to be followed by Hudson and Bauer (Mac Hudson and Joe Bauer), Clark Anthony, and Bobby Rich.
From 1978 to 1999 the station was the broadcast home for the San Diego Padres baseball team. From roughly 1975-1989, KFMB was one of the top three highest rated stations in San Diego, frequently fighting its FM sister, B-100, for the top position. From 1998 to 2004 it was the flagship of the San Diego Chargers football team.
On October 6, 2015, Midwest Television entered into a joint operating agreement with Local Media San Diego LLC, which operates three radio stations licensed to Tijuana but broadcasting in English for the San Diego media market: 92.3 XHRM-FM, 91.1 XETRA-FM, and 90.3 XHITZ-FM. They formed an entity known as "SDLocal" to market all five stations together. Management said the intent of the agreement was to "[preserve the] local ownership and operation of San Diego's top-rated radio stations".
Local programming includes Mike Slater from 10 a.m. to 2 p.m. and Brent Winterble from 2 to 6 p.m. News Anchor Marna Davis does the news every half-hour. Weekend programming includes shows on money, cars, computers, gardening and law, as well as family financial advisor Dave Ramsey. CBS Radio News is heard at the beginning of most hours.
According to a March 2009 L.A. Times article, then-KFMB host Rick Roberts was one of several conservative talk radio hosts in California to have a weekly audience of more than 100,000. Commentary from Paul Harvey had aired on KFMB from June 2005 until his passing in 2009.
