The station featured local talk, including women's interest, political and other subjects live for over 18 hours every day.

In April 2017, the station began simulcasting on 1640 KBJA, also licensed to Sandy, just prior to a switch to exclusively broadcasting on 1640 full-time on May 1, 2017.

On June 21, 1982 the station changed its format and call sign to KZJO, broadcasting contemporary hits identifying itself as "63 Joe."

KTKK applied to the Federal Communications Commission (FCC) to move to new towers near North Salt Lake, Utah, but the application was dismissed.

The station also had an application to change its community of license to Kearns, Utah, and reduce daytime and nighttime power levels.
