Before the mid-1970s, the station was a simulcast of WTOC (AM), and had the callsign of WTOC-FM. Before it was an Urban Contemporary formatted station, it had a long stint as a country music formatted station to compete with daytimer WEAS. In the late '80s and early '90s, the callsign WCHY was part of the station's identity as a country station ("WCHY 94.1 Continuous Country"; the station would sometimes refer to itself as "Y-94".), thus the callsign's creation, as at that time it stood for We're Country Hits Y'all. Later, this station was WSCA-FM - "Cat Country 94."
The station's previous callsign, WCHY-FM, is now in Madison, Wisconsin at Entercom-owned "105-1 Charlie FM-We Play Anything!" That station later flipped to Adult Top 40 in September 2012.
