WLAC is a clear channel radio station based in Nashville, Tennessee. WLAC is owned by iHeartMedia, Inc., airing a Talk radio format, consisting mainly of nationally syndicated hosts such as Rush Limbaugh, Sean Hannity, Glenn Beck and Dave Ramsey. The station's studios are located in Nashville's Music Row district and the transmitter site is in the city's Northside. WLAC operates at 1510 kHz on the AM dial. WLAC's is the only 50,000 Watt, Class A station in North America which operates on 1510 AM,〔http://transition.fcc.gov/fcc-bin/amq?state=&call=&arn=&city=&freq=1510&fre2=1510&single=1&type=3&facid=&class=&list=1&dist=&dlat2=&mlat2=&slat2=&NS=N&dlon2=&mlon2=&slon2=&EW=W&size=9〕 sharing the frequency with 50,000 watt Class B station WMEX,〔http://transition.fcc.gov/fcc-bin/amq?call=WMEX〕 Boston. WMEX and WLAC mutually protect each others' nighttime coverage. 〔https://transition.fcc.gov/ftp/Bureaus/MB/Databases/AM_DA_patterns/606726-76435.pdf〕 ==Early history== Its first broadcast took place on November 24, 1926. The call letters were chosen to contain an acronym for the first owner of the station, the Life and Casualty Insurance Company of Tennessee. Studios were located on the fifth floor of the Life and Casualty building in downtown Nashville. In 1928, it became Nashville's CBS Radio affiliate, while its main competitor, 650 WSM, was affiliated with NBC, the other major Radio network in the early days of broadcasting. The early years of the station featured, as most big-city stations of that time, network programming, local news, studio-orchestra musical features (accompanied by an in-studio pipe organ), farm reports, and some educational programming. Its main competitor in that era, WSM, became known as the radio station where country music essentially developed and became a national phenomenon. When country music became a big business in the late 1940s, WLAC added early-morning and Saturday-afternoon shows in an attempt to steal some of WSM's thunder. Otherwise, the station prided itself as a pillar of the community and placed emphasis on general full-service programs. In 1942, the station boosted its power to 50,000 watts, becoming the second clear-channel station in Tennessee behind WSM. Its daytime signal is somewhat weaker than that of WSM, due in part to WLAC's higher frequency on the dial. The daytime signal reaches parts of five states. Some close-in suburbs of Nashville, like Murfreesboro, get only a grade B signal from WLAC. However, its nighttime signal reaches parts of 28 states and three Canadian provinces. 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「WLAC」の詳細全文を読む スポンサード リンク
