AOR
By 1991, the AM and FM stations broke into separate programming with the 1390 kHz facility taking an [[adult standards]] format (one that would be revisited in 1999 when WNIO's call letters and format moved to that dial position), while the 101.1 MHz became the exclusive home of the Top 40 format. Excluding a period of several months when WHOT-FM carried an [[Album-oriented rock|album rock]] format in late 1991-early 1992, the station has since continued playing Top 40 contemporary hits.
