The transmitter is on West Waters Road at South Zeeb Road, west of downtown Ann Arbor. History Early years The station signed on the air on . The original call sign was WOIA and it was co-owned with WOIB in Saline, Michigan. Originally, WOIA and WOIB simulcast a full service, middle of the road (MOR) music format with some Top 40 music played on weekends. The format changed to full-time Top 40 in 1967. WOIA disc jockeys during this time included John Records Landecker, later to become a legend in Chicago radio, and Art Vuolo Jr., later to become known as "Radio's Best Friend." In 1970, the stations became WNRS AM/WNRZ FM "Ann Arbor's Winners." The "Winners" airstaff included Arthur Penhallow, who later became a fixture at WRIF in Detroit for nearly 40 years.

"Winners" took advantage of Ann Arbor's status as a breakout market for songs that later went on to success in the Detroit market, proclaiming: "Winners Plays... Detroit Watches." The two stations soon separated their programming, with WNRS adopting a country format and WNRZ becoming a full-time 24-hour free-form progressive rock station. Former WABX personalities Jerry Goodwin and Ann Christ worked at WNRZ in 1972, and John Sinclair also hosted a Sunday-evening show. The station built up a loyal following in Ann Arbor's "hippie" community, but was financially unsuccessful. That led owner Thomas Boodell to change the station to a simulcast of WNRS's country programming and change the locks at the station to keep the former progressive-rock hosts out of the studio. After a petition to restore the progressive programming generated 10,000 signatures, Boodell relented by reinstating progressive rock on the station nightly from 9 p.m. to 6 a.m. This split format continued until November 1974, when the station became again temporarily a full-time simulcast of WNRS as preparations were made for the stations' sale to Community Music Services of Rochester, New York. At this time, the FM station's facilities were upgraded. WNRZ-FM was a pioneer in the many aspects
