WOC is a news and talk radio station, licensed to Davenport, Iowa, and operating with a power of 5 kilowatts on 1420 kilohertz. Owned by iHeartMedia, Inc., with studios at 3535 East Kimberly Road in Davenport (along with KMXG, KUUL-FM, WLLR-FM, KCQQ-FM and WFXN), its transmitter is located at an antenna farm in Bettendorf, Iowa, near the Scott Community College Campus. (WOC is the only remaining AM station at this site, as all the other transmitters are for FM radio or television.) WOC's most famous employee was future U.S. President Ronald "Dutch" Reagan, who got his start in radio there in 1932, broadcasting football games. ==Pre-history== WOC's pre-history was complex, with roots extending back to the earliest days of radio. Robert K. Karlowa had an longtime interest in radiotelegraphy, starting in 1907,〔''Education's Own Stations'' (Palmer School of Chiropractic section) by S. E. Frost, Jr., 1937, page 315.〕 and by early 1913 was "the chief operator of the Tri-Cities Wireless club",〔"Karlowa Gives Scientific Talk", ''Rock Island Argus'', February 10, 1913, page 12.〕 which met on the sixth floor of the Best Building in Rock Island, Illinois. In mid-1915, he and Ray E. Hall, representing the Tri-City Radio Laboratory, were issued an Experimental license for station 9XR,〔"Special Land Stations", ''Radio Service Bulletin'', May, 1915, page 4. (The "9" in 9XR's callsign identified the station as being located in the ninth Radio Inspection district, while the "X" indicated that it was operating under an experimental license.)〕 which also operated from the Best Building. This station used a spark transmitter and could only transmit Morse code, so it was never used for entertainment broadcasts. Moreover, effective April 6, 1917, with the entrance of the United States into World War One, all civilian stations were ordered to shut down for the duration of the war, and 9XR permanently disappeared. The civilian ban on radio stations was lifted in October, 1919, and the introduction of vacuum-tube radio transmitters now made audio broadcasts possible. Karlowa's subsequent activities were divided between two separate stations. Karlowa himself was issued a standard amateur license, with callsign 9BC, for his home in Davenport, Iowa. On December 3, 1919〔"1919—The Year the Big Drought Struck Davenport", ''Davenport Democrat and Leader'', July 17, 1924, Page 45.〕 he began broadcasting a series〔"Concerts by Wireless Telephone Fad in Iowa", ''Washington Herald'', March 2, 1920, page 3.〕 of concerts. A second standard amateur license, 9BY, was issued in the name of the Young & McCombs department store, located in the Best Building in Rock Island,〔''Radio Manufacturers of the 1920's: Volume 3—RCA to Zenith'' (Tri-City section) by Alan Douglas, 1991, page 187.〕 where Karlowa was the head of the radio department. 9BY would feature an even more extensive selection of programs. It was announced that, starting about September 1, 1920, the station would broadcast regular concerts on Thursday evenings.〔''QST'', September, 1920, page 44.〕 A few weeks later, on election day, November 2, 9BY broadcast election results,〔"Radio Amateurs to Get Returns", ''Decatur Review'', November 1, 1920, page 14.〕 and later that month it was reported that its weekly broadcasts featured promotional phonograph records provided by the Pathé Frères Phonograph Company.〔"Pathe Special Offer Popular", ''The Talking Machine Trade,'' November 20, 1920, page 60.〕 In early 1921, Karlowa formed the Karlowa Radio Corporation, which bought the Young & Combs radio department assets,〔Douglas, page 187.〕 and took over operation of 9BY, still located in the Best Building in Rock Island. The station maintained its Thursday evening concert schedule.〔"9BY, Rock Island, Ills.", ''QST'', March, 1921, page 42.〕 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「WOC (AM)」の詳細全文を読む スポンサード リンク
