WRIS-FM's history dates back to October 2005, when Mid-West Family Broadcasting began testing the 106.7 FM signal under the call sign WYZM, airing smooth jazz music normally heard on sister station WMGN during its "Magic Sunday Morning" program.

The smooth jazz was there only temporarily, for on December 1, 2005, WYZM changed to WSLK and began simulcasting the classic hits format of sister station WHLK ("The Lake at 93-1 and 106-7").

The full WTDY schedule was simulcast on WTDY-FM, including local shows Sly in the Morning and Forward with Kurt Baron; full-hour local newscasts at 12 p.m. and 5 p.m.; national shows including Michael Smerconish and America's Radio News; and weekend broadcasts of NFL and college sports from Compass Media Networks and Sports USA.

News/talk programming continued on WTDY-FM until November 21, 2012, when morning host John "Sly" Sylvester and the station's entire news staff received layoff notices and automated Christmas music began playing.

During its time as a sports-formatted station, WOZN-FM relied on a combination of CBS Sports Radio, local, and state-wide programming, the latter including "The Bill Michaels Show" (11AM-2PM), which originates from Milwaukee's WSSP.
