WZNX calls itself The Fox, a reference to the X in its call letters, and the F in the call letters of its onetime sister-station, WZNF (95.3 FM) licensed out of Rantoul, Illinois. The Cromwell Radio Group bought the radio station in the mid-1990s, kept the call letters and the "Fox" identifier. Among the disc jockeys during this time were Chris Anderson, Brian Rickman, Lars Christiansen and Wes Adams.
WZNX self-designates as The Fox, drawing inspiration from the X and F present in its call letters, much like its predecessor WZNF with its own set of call letters.
