WDHA-FM 105.5 FM is a mainstream rock music station licensed to Dover and Morristown, New Jersey. WDHA is owned and operated by Greater Media and serves the northern New Jersey region.
The station focuses both on rock music of the 1970s and 1980s as well as rock music from the 1990s, 2000s, and today. The station will go as far back as the 1960s on occasion. The station plays both classic rock and newer rock cuts and calls itself "The Rock Of New Jersey." Core artists include the Rolling Stones, Led Zeppelin, Mötley Crüe, Queen, Pearl Jam, Metallica, Nirvana, The Doors, Foreigner, Aerosmith, Van Halen, Ozzy Osbourne, Whitesnake, Rush and many others. The station is local and live full-time. The station's facilities are located in Cedar Knolls outside of Morristown.
In terms of ratings, the station dominates in northern New Jersey, especially in Morris County, where it is based. One reason was the lack of a modern rock station in New York City in 2006 and early 2007. WAXQ (Q104.3), which plays Classic Rock, was the only rock station in the New York market. This void was created by WXRK "92.3 K-Rock" when that station briefly became WFNY "Free FM", a talk station, on January 1, 2006, and ended when it changed back to K-Rock on May 24, 2007 until March 11, 2009, when it became "92.3 Now FM". WDHA always garnered high ratings in northern New Jersey, even when New York had as many as three full-time rock stations.
