The dual frequency sharing arrangement between WBAP and WFAA continued through the 1950s and 1960s, with the stations switching frequencies several times a day. When WBAP changed frequencies, it signaled the change with a cowbell, which became widely associated with the station. Even though the stations swapped frequencies several times each day, the network affiliations remained constant: NBC network programming stayed on 820 kHz and ABC network programming stayed on 570 kHz. This frequently proved confusing for announcers and listeners alike.
