 Finally, on September 29, 1998, at 5 PM eastern time, WAQZ at 107.1 FM played its last song, "Closing Time" by Semisonic.Immediately after the song ended, WAQZ became KISS 107 FM, with new call letters WKFS, and permanently switched to the top 40 format.Throughout the rest of 1998, 1999, and early 2000, Oxford's 97X was again the only alternative music offering in the entire Greater Cincinnati region, leaving many potential listeners of alternative music out of the signal's range.
