KCKY aired mostly Spanish language Christian programming, simulcasting with KSAZ in Tucson much of the time through a local marketing agreement with that station's owner.
[5] By the late 1950s, Gila owned five AM stations and one FM: KCKY, KCLF 1400 Clifton, KGLU 1480 Safford, KVNC 1010 Winslow, and KZOW 1240/KWJB-FM 100.3 Globe.
Additionally, the Federal Communications Commission (FCC) also contended that the Gila stations refused to join the CONELRAD civil defense system, charges denied by Gila's engineer who said that the systems were installed at great difficulty due to the remote locations of their facilities,[6] and that inspectors found improperly maintained meters, missing logs, and gates that were not padlocked.
[13] The day before the FCC canceled the Gila chain's callsigns, on January 16, 1963, the Coolidge Broadcasting Corporation, owned by Craig and Kathleen Davids and Paul Dean Ford, applied to build a new station using KCKY's facilities.
In its later years with Grande Voz, KCKY was the first all-sports station in Arizona,[17] with affiliations with the Chicago Cubs and later Colorado Rockies radio networks as well as carriage of Phoenix Suns games and University of Nebraska Cornhuskers football.
