Owned and operated by Salt Lake City–based Bonneville International, KKFN airs a sports radio format.

KKFN runs local sports shows days and evenings, and carries ESPN Radio programming late nights and weekends.

Western Cities got the Federal Communications Commission to permit 104.3 to boost its power to 58,000 watts, now covering more of the Denver market.

The station switched to an adult contemporary music format, changing its call sign to KQKS, and branded as "104.3 Kiss FM".

On January 8, 1997, Jefferson-Pilot (which later became part of the Lincoln Financial Group) moved the KQKS call sign and Rhythmic Top 40 format to 107.5 MHz.

On December 8, 2014, Entercom made plans to purchase Lincoln Financial Group's entire 15-station lineup in a $106.5 million deal.

On December 22, 2014, Entercom announced that it would spin off KKFN to the Pike's Peaks Trust, in anticipation of selling it to a third party group as part of a divestiture deal.
