November 12 In Radio HIstory

In 1947...KPO-AM San Francisco changed its call sign to KNBC. (Today the station is KNBR)

KNBR began life 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 Hale store at Market and 5th (now the site of Nordstrom), 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 NBC's 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 NBC's flagship station on the West Coast, it had a full-time orchestra, five studios, and produced many live shows. During the rise of Hollywood, NBC's 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 radio's 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, KPO's news bureau was the major source for 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 12, 1947, the Federal Communications Commission approved NBC's application to change the call sign from KPO to KNBC, to shore up its reputation as an NBC station (and the only radio station NBC ever owned on the West Coast). This change lasted until 1962, when the network moved the call sign to its television station in Los Angeles and the radio station was renamed KNBR.
