On October 31, 1988, the FCC granted a permit to Sungilt Corporation to construct a full-service television station on UHF channel 46 to serve Green Valley and surrounding area.
In January 2002, shortly after resuming program testing, Sungilt agreed to sell the station to Univision, which had been serving Tucson with KUVE-LP, a low-power translator of Phoenix station KTVW-TV.
