KQCK

The station was originally assigned the call letters KDBJ when the station was first licensed by the Federal Communications Commission on August 14, 1985. The station first signed on the air on August 28, 1987 as KKTU. It originally operated as a satellite station of NBC affiliate KTWO-TV (channel 2, now an ABC affiliate) in Casper. 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. Prior to 1987, NBC programming had been relegated to off-hours clearances on KGWN-TV (channel 5), although the network's Denver affiliate KCNC-TV (channel 4, now a CBS owned-and-operated station) had been available in the area on cable television for decades. For a time starting in 1995, KKTU (along with KTWO) had a secondary affiliation with The WB.[2]

On September 1, 2003, the NBC affiliation in Casper moved from KTWO to KCWY (channel 13). Although KTWO temporarily became an independent station at that time until it could acquire the ABC affiliation from KFNB (channel 20), KKTU was able to immediately switch to ABC; it began branding itself as "ABC 8," in reference to its channel placement on Cheyenne area cable systems. This made Cheyenne one of the last markets in the country to have an ABC affiliate. Before the switch, cable systems piped in Denver's ABC affiliate—first via KUSA-TV (channel 9), then from KMGH-TV (channel 7) following a three-way network affiliation switch that occurred on September 10, 1995. KMGH had actually operated a translator in Cheyenne since the late 1990s. On May 31, 2005, the station changed its call letters to KDEV, with plans on expanding its signal into the nearby Denver market. Indeed, it built its digital transmitter in Fort Collins, in the Denver market.

On May 31, 2006, the Equity Broadcasting Corporation sold KTWO to Silverton Media. Equity retained ownership of KDEV, but entered into a local marketing agreement with Silverton to operate it as a satellite of KTWO. Equity later moved the ABC affiliation in Cheyenne to a low-powered repeater, KKTU-LP (channel 40), and switched KDEV's affiliation to its in-house classic television network, the Retro Television Network. On June 8, 2008, KDEV began simulcasting KKTU-LP's ABC programming over its analog signal (restoring the "ABC 8" branding), and on its second digital subchannel. Nine days later on June 17, 2008, the station changed its call sign to KQCK.

On January 4, 2009, a contract conflict between Equity and Luken Communications (which had acquired RTN in June 2008) resulted in many RTN affiliates losing the network's programming.[3] 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, effective immediately.[4] RTN would eventually sign a deal to affiliate with Sterling-based KCDO-TV (channel 3) that May.[5] KQCK subsequently switched to AMGTV, and then later to @SportsTV.

On April 16, 2009, KQCK, along with two other television stations, were purchased at auction by Valley Bank for $7 million.[6] Valley Bank, in turn, filed to sell KQCK and Aurora, Colorado repeater KQDK-CA to an ownership group connected to Fusion Communications on September 9.[7] ABC programming remained on KQCK-DT2 and channel 40, by then renamed KDEV-LP, until 2009, when KTWO began simulcasting its programming over the second digital subchannel of KLWY (channel 27). KQCK and KDEV-LP eventually parted ways; the latter station eventually switched to MyNetworkTV and then Me-TV before shutting down in 2012.

In January 2010, KQCK joined the Spanish language network VasalloVision.[8] KQCK was acquired by Casa Media Partners in April 2012.[9] The station subsequently switched its affiliation to MundoFox on August 13, 2012;[10] in late 2014, KQCK dropped MundoFox for the Christian Television Network.[11][12] Casa Media Partners filed for Chapter 11 bankruptcy on April 14, 2015.[13] On January 9, 2017, CTN's parent company, the Christian Television Corporation, agreed to purchase KQCK outright;[14] the sale was completed on June 30, 2017.[15]
