Prior to 1974, KRKK was known as KVRS and was operating on 1400 kHz. That station signed on in 1942. The station became KRKK at 5:30 AM on September 1, 1974. During its beginnings, the station carried top 40 programming, but switched to Oldies some time in the 1980s. Until early May 2009, the station aired an oldies format from Citadel Media. The switch to talk occurred the first week of the month and the station became a conservative talk station.
At 5,000 watts during the day, KRKK drops to 1,000 watts at night with a directional signal to protect other stations on 1360 kHz. Reception of the station begins to fade near the Sweetwater County line to the east and west, however under the right conditions KRKK can be heard much farther distances. KRKK has three sister stations KSIT 99.7, KQSW 96.5 and KMRZ 106.7 FM.
