On August 28, 1989, the station increased its power to 50,000 watts, changed call letters to WOZZ (using branding and imaging that alluded to The Wizard of Oz), and flipped from country to adult contemporary.

However, to this day, the station maintains a control room and sales office in Appleton to meet Federal Communications Commission requirements.

The "93 Rock" format had recently been adopted on Midwest Communication-owned sister stations in Duluth (on KDAL-FM) and Wausau (on WOZZ, the call sign was transferred from WRQE's previous classic rock format to the Wausau station at the time of the flip).

On September 12, at Midnight, both 93.5 and 93.1 flipped to a classic country format, branded as "93.5 Duke FM," that complements Midwest's contemporary country-formatted WNCY-FM.

("Duke" is a reference to John Wayne, and was first applied by Midwest to a Terre Haute station that converted to classic country earlier in 2014.)
