WNAR was on the air from at least 1947 serving Norristown and Montgomery County as a 500 watt daytimer on 1110 AM. Until the late 1960s, much of the service area was rural and undeveloped, with the signal barely reaching Philadelphia. In the 1960s and 1970s, the station was owned by Victor Mauck.
In 1965, the station began programming a middle of the road format, and by the late 1960s, the station was selling time-brokered slots. Between paid programs, a top 40 format was heard with hosts Johnny Deveraux and others. Some of the WNAR staff included KYW's Al Novak, Dan Baker, Cousin Larry with the morning show, Ron Joseph, and "Super Lou."
In the 1970s, a syndicated beautiful music format debuted with the voice of John Doremus.
The station was sold in 1984 and the call letters became WGHW, switching to the current calls of WNAP in 1987. The station now programs a gospel music format under the name "Gospel Highway Eleven" with 4,800 watts, covering much of the Philadelphia area.
