WTHK, known on-air as "The Hawk" was a radio station located at 97.5 FM which had a classic rock format. Although the station was originally licensed to Trenton, New Jersey, changing to Burlington, New Jersey in early 2006, The Hawk targeted the Philadelphia broadcasting area in addition to its own local region. Its transmitter was located in Ewing Township. In February 2005, WTHK flipped frequencies with sister station WPST, moving from 94.5 to 97.5 FM. The WTHK calls are now used in Wilmington, Vermont, on the former WVAY 100.7, a classic rock station owned by Nassau Broadcasting.
