The station has always been short-spaced due to adjacent channel interference from WMGM in Atlantic City, WXCY in Havre de Grace, Maryland, and WNNJ in Newton, New Jersey (all located on 103.7 FM), WAEB-FM in Allentown and WNNK in Harrisburg (both located on 104.1 FM), as well as WRFF (104.5 FM), and co-channel interference from WRCN on Long Island and WFAS-FM in Bronxville, New York.
The move was part of a shakeup in the market when sister station WNNK shifted to Adult Top 40 and to counter Rhythmic-leaning Top 40 Mainstream rival upstart WHKF-FM, a move that has paid off for them in terms of ratings.
