In February 1998, the station's call sign was changed to WYXX and it adopted a rhythmic oldies format branded "Chicago's Heart and Soul", simulcasting 103.1 WXXY in Highland Park, Illinois, with the station's call sign and adult contemporary format moving to 95.7.[2] [5] [6] In August 1999, WYXX and WXXY adopted a 1980s hits format as "The Eighties Channel," with the station patterned on high-energy CHR stations of the 1980s.[7] [8] [9] The station featured longtime Chicago area radio personalities including Robert Murphy, Fred Winston, and Mark Zander.[7] [9]
