KNBRs non-directional 50.000-watt class-A signal can be heard throughout much of the western United States and as far west as the Hawaiian Islands at night.

The stations studios are located at 750 Battery Street in San Franciscos Financial District.

Between the three stations, games of the San Francisco Giants, San Francisco 49ers, Oakland Panthers and Stanford Cardinal are broadcast to the San Francisco Bay Area. KTCT is available in the HD format on 1050 kHz. In addition, KNBR is simulcast on the HD2 subchannel of KSAN in nearby San Mateo.


1. History

KNBR began broadcasting on April 17, 1922 as KPO, a 100-watt station owned by the Hale Brothers department store. In 1925, the San Francisco Chronicle newspaper bought half-interest in the operation. Originally located in the department store at 901 Market between 5th and 6th, its horizontal wire antenna on the roof was so efficient, it immediately attracted the attention of audiences all over the Pacific Coast.

In 1927, KPO became an affiliate of the new NBC radio network. In 1933, KPO was sold to NBCs parent company, the Radio Corporation of America RCA, and its operation was consolidated into that of its co-owned KGO at the Hunter-Dulin Building, 111 Sutter Street. From there, NBC operated its West Coast network, feeding dozens of stations and operating a news bureau to serve NBC. As NBCs flagship station on the West Coast, it had a full-time orchestra, five studios, and produced many live shows. During the rise of Hollywood, NBCs radio operation was moved to Los Angeles.

In 1941, just before World War II, NBC constructed Radio City at 420 Taylor Street, considered one of the best radio facilities built during radios golden age. However, with the network control having been moved to Los Angeles, the San Francisco NBC building was never fully utilized.

During World War II, KPOs news bureau was the major source of NBC of news about the war in the Pacific, and operated shortwave radio stations transmitters located in Dixon serving the world. It was at the KPO RCA shortwave facility that the message was received that Japanese emperor Hirohito had surrendered, ending World War II.

On November 23, 1947, NBC changed KPOs call sign to KNBC, to strengthen its identity as an NBC station and the only radio station NBC ever owned on the West Coast. This change lasted until fifteen years later, when the network decided to move the KNBC identity to its television station in Los Angeles. NBC had asked the FCC to restore the KPO call letters to the San Francisco radio station but later withdrew that request and 680 AM was renamed KNBR on November 11, 1962.

In November 1949, NBC television affiliate KRON-TV went on the air. Only before the TV stations first airdate did NBC fight for the construction permit for the TV station until it lost the bid to the de Young family, then the owners of the San Francisco Chronicle.

In the 1950s when NBC scrapped its radio comedy, drama, variety shows, and serials, the Los Angeles facility was sold and demolished, and KNBC/KNBR once again became the West Coast NBC network control center and West Coast NBC Radio news operation.

KNBR evolved into a Middle of the road music format mixing in Adult Standards with Soft Rock cuts by the early 1960s. The station continued to be a news intensive format with personalities in the foreground and music in the background. Personalities included Frank Dill, Mike Cleary, Les Williams, Dave Niles, and Jack Hayes. Until January, 1975, KNBR carried NBCs long-running weekend show, Monitor. By the mid-1970s, KNBR evolved musically into a straight ahead adult contemporary music format and continued as such into the 1980s.

In March 1989 NBC sold KNBR to Susquehanna Radio Corporation; it was the last radio property held by NBC, which two years earlier made the decision to sell off its radio division following General Electrics 1986 acquisition of RCA. The station soon added some sports talk in evenings, and took a full-time sports format in 1990 with the lone exception of The Rush Limbaugh Show, which KNBR carried from 1988 until 2000.

KNBR carried programs from ESPN Radio and KTCT aired shows from both ESPN Radio and Fox Sports Radio until 2013, when both stations switched to the Cumulus-distributed CBS Sports Radio.

In 2015, KNBRs studios were relocated from 55 Hawthorne Street to 750 Battery Street after parent Cumulus Media consolidated its San Francisco radio stations in one building.

In June 2018, KNBR began broadcasting in HD Radio on KSANs HD2 channel.

KNBR added an FM simulcast on 104.5 on September 6, 2019 and became KNBR-FM.

In 2005, KNBR became the official radio home of the San Francisco 49ers. All games are also heard on sister station KSAN; some AM broadcasts may be moved to KTCT due to conflicts with Giants games. 49ers games were broadcast by Joe Starkey and Gary Plummer for four seasons until Starkeys retirement following the 2008 season. In the 2009 season, former Giants baseball and world-class tennis announcer Ted Robinson took over for Starkey as the play-by-play announcer.
