KCRA-TV (channel 3) is a television station in Sacramento, California, United States, affiliated with NBC. It is owned by Hearst Television alongside Stockton-licensed MyNetworkTV affiliate KQCA (channel 58). Both stations share studios on Television Circle off D Street in downtown Sacramento, while KCRA-TV's transmitter is located in Walnut Grove, California. History The station first signed on the air on September 3, 1955. It was founded by the Central Valley Broadcasting Company, a partnership of the Kelly and Hansen families of Sacramento. Central Valley Broadcasting also owned KCRA radio (1320 AM, now KIFM, and 96.1 FM, now KYMX); the AM station's call letters were intended to be "KRCA", but the middle two letters were erroneously transposed by a typist at the Federal Communications Commission (FCC) when that station's original license was drafted in 1945 and was never corrected. By the time KCRA-TV went on the air, the KRCA call letters had already been taken the previous year by NBC's owned-and-operated station in Los Angeles (originally KNBH, now KNBC). The station's longtime original studios were located at 310 10th Street in Sacramento. KCRA-TV inherited the NBC affiliation from KCCC-TV (channel 40, channel now occupied by Fox affiliate KTXL), which became the Sacramento market's first television station when it signed on in September 1953, which had also carried affiliations with ABC, CBS and DuMont until other stations debuted in the market. However, it in turn also received the affiliation as a result of KCRA radio's decade-long affiliation with the NBC Radio Network. KCRA was the third of Sacramento's VHF stations to sign on exactly within a year behind KXTV and KOVR—all signing on in six-month increments. In 1959, under the direction of then chief engineer, William Herbert Hartman, construction began on a new transmission tower near Walnut Grove to transmit the signals of KCRA-TV, KXTV and KOVR; the tower was completed in 1961. Upon the death of KCRA co-founder Ewing C. Kelly in 1960, son Bob Kelly (who was KCRA's station manager, commercial manager and film buyer) became president of KCRA, Inc., while son Jon Kelly (who served as its local sales manager) was named general manager. In January 1962, KCRA-TV began transmitting its signal from the Walnut Grove tower, which became the tallest structure in the state. In April of that year, the FCC approved the sale of the Hansen brothers' 50% share of the KCRA stations to Bob, Jon and their
