 On July 19, 1994, the FCC granted to Gonzalo A Santos a construction permit to build a low-power television station to serve the San Antonio, Texas area.The station was given the callsign K57GO, to operate on UHF channel 57.After two extensions of the construction permit, the latter resulting in the station's callsign being deleted, but later restored on approval, Santos sold the station to Three Angels Broadcasting Network (3ABN) in September 1996.
