KTCL (93.3 FM) – branded Channel 93.3 – is a commercial Alternative Rockradio station, licensed to Wheat Ridge, Colorado. Owned iHeartMedia, Inc., KTCL serves the Denver metro area. The KTCL studios are located in Denver, while the station transmitter resides in Golden.
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.
In 2007, KTCL changed its city of license to Wheat Ridge to provide clearer coverage over the Denver area. It can still be received in Fort Collins.
KTCL has become a source of pride for listeners of modern rock in Colorado, largely due to its commitment to the promotion of local modern rock bands. This promotion of local bands was the primary catalyst for success for the aforementioned bands. In fact, the unexpected and immense success enjoyed by The Fray as a result of their promotion by KTCL has caused many Colorado modern rock listeners to refer to The Fray as "93.3's baby."
