The station signed on in September 1965 as KFMF licensed to Fort Collins, Colorado. It simulcasted the Top 40 format of KIIX AM 600 (now on 1410, the old 600 frequency is now KCOL). In the 1970s, the station became KIIX-FM and adopted a freeform Progressive Music format. It changed its calls to KTCL in 1975 and evolving to the modern rock format in the mid 1980s.

KTCL, part of a joint sales agreement with KBPI and KRFX in 1995, moved to a more pop-oriented direction when KBPI began playing more new rock.[1] In 2001, KTCL aired the daily program Martha Quinn's Rewind along with at least four other stations owned by Clear Channel.[2]

In 2007, KTCL changed its city of license to Wheat Ridge to provide clearer coverage over the Denver area, though it can still be received in Fort Collins.

KTCL airplay was noted for having helped launch several local alternative bands, including Love .45, Flobots, 3OH!3, The Fray, and Tickle Me Pink.[3][4][5]

Unlike most alternative stations owned by iHeartMedia, KTCL has maintained its local programming and disc jockeys.
