The station has previously gone under several call signs in its past. At its inception, the station was known as KSXX. During the early 1960s, the station was not a talker as it is now, but played music, becoming a talk station in the 1965. It previously only operated during the day only, but was later allowed to continue broadcasting during the night in 1979 by construction a four tower directional array. On June 21, 1982 the station changed its format and call sign to KZJO, broadcasting contemporary hits identifying itself as "63 Joe." Six months later, the station changed formats again, back to its current format of talk radio and on August 5, 1985, the station changed its call sign to the current KTKK. The station's previous towers were displaced by a housing development. It now shares tower space with KLLB which broadcasts from a tower in South Jordan, Utah. Ironically, the KLLB tower may soon have to be demolished due to another housing development. KTKK applied to the FCC to move to new towers near North Salt Lake, Utah but the application was dismissed.
