The station first signed on the air on September 2, 1958, as KAYS-TV. The station was initially a primary affiliate of ABC. KAYS-TV was founded by Hays businessmen Ross Beach and Bob Schmidt, owners of radio station KAYS (1400 AM); the television station was housed in an expansion to the radio studio building. KAYS faced stiff opposition from KCKT (channel 2, now KSNC), which signed on in November 1954 and was affiliated with NBC in concert with Garden City sister station KGLD (now KSNG). The construction of KAYS-TV was marred by tragedy when a pulley broke, causing 22-year-old Ronnie Barnett of Oklahoma City, employed by a tower crew, to fall 150 feet to his death; another person survived.
