The station first signed on in 1948 as KSPA.[1] In August 1966, station owner Franklin James sold KSPA to Rancho Broadcasting, owned by television engineer William F. Wallace, for $120,000.[2] The following year, the station changed its call sign to KQIQ[3] and adopted a country music format, later switching to top 40. In January 1974, the station changed its call letters to KAAP, flipping to an all-news format by the end of 1975.[4] [5] Rancho Broadcasting signed on an FM sister station, (96.7 FM), in 1976.[6] The company sold for $1.2 million in late 1980.[7]
During the 1990s, the station was known as KKZZ and broadcast an adult standards format.[8]
In February 2013, KKZZ began airing Radio Fórmula, a Mexican news/talk radio network. In March 2017, it added an FM translator station at the 102.5 FM frequency.
