KQCK was originally assigned the call letters KDBJ when the station was first licensed by the Federal Communications Commission on August 14, 1985.

As a result of KKTU's sign-on, Cheyenne became one of the last markets in the United States to receive full-time affiliations from the three major broadcast networks.

On May 31, 2005, the station changed its call letters to KDEV, with plans on expanding its signal into the nearby Denver market.

Equity retained ownership of KDEV, but entered into a local marketing agreement with Silverton to operate it as a satellite of KTWO.

[4] As a result, Luken moved RTN's operations to its headquarters in Chattanooga, Tennessee, and dropped its programming from all Equity-owned affiliates, including KQCK and KQDK, effective immediately.

On April 16, 2009, KQCK and KQDK, along with two other television stations, were purchased at auction by Valley Bank for $7 million.

[7] Valley Bank, in turn, filed to sell the stations to an ownership group connected to Fusion Communications on September 9.

[11] Concurrent with the launch of KQDK's digital signal, on February 12, 2013, the station modified its call sign to KQDK-CD.
