However, on July 11, 1976, it switched its primary affiliation to ABC and dropped all NBC programming. KEVN-TV signed on in Rapid City that day as a full-time ABC affiliate, and KYCU/KSTF felt obliged to fill the ABC void in Scottsbluff, as KOTA-TV in Rapid City and its Scottsbluff satellite, KDUH-TV (now KNEP), were primary NBC affiliates with a secondary CBS affiliation. Wyneco sold the station to Burke Broadcasting in 1983. When KOTA/KDUH switched to ABC in June 1984, KYCU/KSTF switched its primary affiliation to CBS, with ABC and NBC as secondary affiliations. However, as the 1980s wore on, the station began gradually phasing out NBC programming.
