The station began its history on December 16, 1993 on 94.5 MHz as alternative rock WZJX (94-5 X-Rock), Dayton's first-ever alternative station. George Wymer was General Manager; Randy Scovil was Program Director as well as the afternoon drive host. Steve Stone and Christy Chatman hosted the morning show, Andy Sims did mid-days, and Greg Johns hosted the evening shift. During the six months as an alternative station, X-Rock brought two sell-out shows to the Hara Arena: The Breeders and the Afghan Whigs, and later The Smashing Pumpkins. In the station's first ratings period (Jan–March 1994), X-Rock's ratings in the 18–34 demographic had already grown to half of longtime Dayton rock station WTUE.
