History WLIN/WCAR-FM years Detroit's 92.3 FM began with a Federal Communications Commission (FCC) construction permit under the call sign WIPE. The permit was originally granted in 1960, held by jazz disc jockey Sleepy Stein and Hollywood composer and musician Henry Mancini. The construction permit specified a power of 10,000 watts from a transmitter location atop the Cadillac Tower Building in downtown Detroit. In 1961, David Kelly formed Downriver Broadcasting and purchased the construction permit for WIPE from Stein and Mancini. Downriver Broadcasting signed on the station on November 2, 1962, with the call letters WLIN. Bill Hennes hosted the first broadcast from studios on Fort Street at LaBlanc Avenue in Lincoln Park. The studios were built and transmitter installed by chief engineer Art Lebermann. WLIN's original aim was to program a full-service variety format for the downriver Detroit area. The original schedule consisted of morning host Bill Hennes, a two-hour talk show, afternoon drive with Dave Kelly, and evening DJs Ron Rose and Don Haney. In 1963, the station relocated its studios to the Lafayette Pavilion Apartments complex in downtown Detroit, and the format became all jazz music. In 1964, Hy Levinson, owner of successful "good music" outlet WCAR, purchased WLIN and rechristened it WCAR-FM on December 8 of that year. WCAR-FM initially broadcast from 6 a.m. to midnight and simulcast its AM sister's conservative MOR format 100% during that time. In 1969, Levinson hired consultant Ken Draper to modernize the music format for both WCAR and WCAR-FM, and the music mix was adjusted from conservative MOR to contemporary MOR. WCAR AM made a brief attempt at Top 40 in 1971–1972; however, WCAR-FM was separately programmed, remaining a contemporary MOR outlet. Tower 92/WCXI-FM In February 1977, Levinson agreed to
