The station went on the air as KXHC on October 17, 1990. On December 21, 1990, the station changed its call sign to KKYZ.[4]
In 2010, Cochise Broadcasting obtained a second construction permit for a station on 101.7 MHz in Huachuca City, with call sign KXKR. In December 2011, that station was activated at 100 watts, a temporary facility, as the company was in the middle of a lengthy process to move KKYZ into the Tucsonradio market. It would be licensed to Catalina Foothills at 101.1 MHz. An application for such a move was approved in 2020. In 2021, the KKYZ call letters were transferred to the Huachuca City facility, operating on the same facility as the first KKYZ, and the station moving to Tucson changed call letters from KKYZ to KXKR and went silent.[5]
