KRBC-TV, virtual channel 9 (UHF digital channel 29), is a NBC-affiliated television station located in Abilene, Texas, United States. Owned by Mission Broadcasting, the station is operated by the Nexstar Broadcasting Group through a shared services agreement as part of a virtual duopoly with CBS affiliate KTAB-TV (channel 32). The two stations share studio facilities located on South 14th Street in Downtown Abilene. Also, the stations share transmitter facilities located on Texas State Highway 36, in neighboring Callahan County. ==History== KRBC-TV first began its broadcasting operation on August 30, 1953 as the first television station in Abilene. The station was owned by the Ackers family, who had bought the construction permit from Harte-Hanks Communications a few months earlier, along with KRBC radio (1470 AM, now KYYW). The call letters stand for Reporter Broadcasting Company, after the Harte-Hanks-owned ''Abilene Reporter-News''. The tower was originally located atop Rattlesnake Mountain in Cedar Gap. KRBC originally carried a mixture of programming from all four networks of the time--NBC, CBS, ABC and DuMont However, it was a primary NBC affiliate. It lost CBS in 1956 when KPAR-TV (now KTXS-TV) signed on. The two stations shared ABC until KTAB-TV signed on and took CBS, leaving KRBC as an NBC affiliate. In 1962, KACB-TV signed on from San Angelo as a semi-satellite of KRBC. The Ackers family owned the station for 44 years until selling it to Sunrise Television in 1997. Two years later, Sunrise severed the electronic umbilical cord between KRBC and KACB, and KACB became a full-fledged station; it is now KSAN-TV. In 2002, Sunrise merged with LIN Television. In 2003, LIN sold KRBC to Mission Broadcasting. Mission Broadcasting in turn contracted with the Nexstar Broadcasting Group, owner of KTAB, to provide news, traffic, sales, engineering and business operations under a shared sales agreement. In 2005 Nexstar moved the entire KTAB operation from 5410 South 14th Street into the KRBC building at 4510 South 14th Street in Abilene. After consolidating operations under the same studios, the Abilene facility now provides various office and master control functions for Nexstar and Mission stations KLST and KSAN-TV in San Angelo. However, KTAB is still the senior partner. The master control room now operates KTAB and KRBC, as well as KLST and KSAN in San Angelo. Business and traffic operations for both stations are handled here. During a January 14, 2007 ice storm, the KRBC main transmission tower collapsed, taking the station's analog signal off the air for 13 hours. The collapse not only destroyed the tower and the analog antenna but also the station's low power digital transmission antenna. However, the falling tower missed the transmitter building and an adjacent auxiliary antenna; station engineers were able to get KRBC's analog channel 9 signal back on the air using that auxiliary antenna. The collapse also destroyed the antenna for NOAA Weather Radio station WXK29, leaving it off the air until a new antenna was installed. A microwave link on the tower which helped provide programming to KLST and KSAN in San Angelo was also destroyed in the collapse. In October 2007 the San Angelo link was replaced with a dual channel fiber-optic cable.〔(2007 Tower News - Wireless Estimator )〕〔('Tis the season for high-def broadcasting - Abilene Reporter News )〕 The station's digital signal remained off the air until October 2007 when it returned to the air on digital channel 29 with all NBC programming presented in HD.〔〔(KTAB and KRBC TV High Definition TV - Big Country Homepage )〕 The new digital transmitter is based in a new transmitter building at the KTAB-TV tower site near Potosi, Texas. The station also shares a digital broadcast antenna with KTAB. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「KRBC-TV」の詳細全文を読む スポンサード リンク
