WPST

WPST (W Passport Stereo Trenton) has been a Top-40 station in central New Jersey since the mid-1970s.  In 2005, WPST changed their city-of-license from Trenton to Burlington which essentially put it in the Philadelphia, Pennsylvania radio market.  97.5 FM is now Sports formatted WPEN, while the WPST calls now live at 94.5 FM still licensed to Trenton.
