The station expanded its coverage to El Centro in 1965 with another increase in power, and relocation of its transmitter from within the city of Yuma to a site atop Black Mountain, northwest of Yuma, at a much greater height above average terrain. It also opened an office and studio in El Centro to better serve the Imperial Valley. On December 7, 1966, Desert Telecasting filed an application to transfer the stations to Eller Telecasting, part of Eller Outdoor Advertising Company. Ownership of the station would pass to Karl Eller, but the station would continue to be managed by Crites, who became president of Eller Telecasting. KBLU-TV became part of Combined Communications in 1968, when its parent, Eller Outdoor Advertising Company, merged with KTAR Broadcasting Company.
