The station started life as KRIL, and aired a country format in the mid-1970s. When KRIL changed its call sign to KLBQ in 1979, the station dropped the format and flipped to a Top 40 music format under the branding "Q99". Due to major Top 40 competition in the market, the station evolved into a Hot AC format in the 1980s.[4] In the 2010s, the station flipped back to country. On July 13, 2017, both KMLK and KLBQ swapped call signs and frequencies.[5]
