Morgan Murphy sold off WEAU radio in 1959; in 1962, it sold WEAU-TV to The Post Corporation of Appleton (Morgan Murphy would later purchase rival WKBT, channel 8). WEAU's departure from radio proved short-lived as The Post Corporation purchased Chippewa Falls radio station WAXX (1150 AM) in 1963, and two years later, established a new WEAU-FM at 100.7 (moving to 104.5 when the Fairchild tower was built) which largely simulcasted WAXX's country music format. WEAU-FM's call letters were switched to WAXX-FM in 1977, and in 1978, the country format was moved exclusively to WAXX-FM with the AM station becoming WAYY (which later moved to 790 AM in a swap with WEAQ).
