(FCC) awarded the first fifteen commercial FM station construction permits, including an assignment for Salt Lake City on 44.7 MHz to the Radio Service Corporation of Utah, which was also the licensee of AM station KSL. The FM station was issued the call sign K47SL. There were numerous delays before broadcasting began. In early 1941, the FCC began an investigation whether newspaper ownership of radio stations should be restricted, which put K47SL's authorization on hold, because approximately twenty percent of Radio Service Corporation of Utah stock was held by the publisher of the ''Salt Lake Tribune'' and ''Salt Lake Telegram'' newspapers. As of June 1943, K47SL was included in a list of "other construction permit authorizations outstanding for FM stations not on the air". Effective November 1, 1943, the FCC modified its policy for FM call letters, and the station was assigned new call letters of KSL-FM. Equipment and staffing shortages resulted in additional delays, until the station commenced broadcasting on December 26, 1946, at 100.1 MHz,"KSL-FM Starts; On Air Daily for 6 Hours"
