On May 1, 1970, the unique dual split-frequency lives of WBAP and WFAA ended when WBAP paid $3.5 million to WFAA in exchange for sole occupancy of 820 kHz (and the NBC affiliation). WFAA took on 570 kHz (and the ABC affiliation), but with only 5,000 watts full-time. Once the frequency-sharing with WFAA ended in 1970, both stations were free to program musical formats, and WBAP began programming country music. It also gained the added benefit of 820's clear-channel signal; previously WFAA controlled it during these prime nighttime hours.
