The transmitter antenna is on the WHP-TV broadcast tower on Blue Mountain in Susquehanna Township, Dauphin County at (40°20′43.3″N 76°52′7.9″W / 40.345361°N 76.868861°W / 40.345361; -76.868861).

In the 1950s, WHP-FM duplicated WHP about 50% of the broadcast day, with the remainder devoted to instrumentals and some classical music programming.

The station played quarter-hour sweeps of soft instrumental music, including cover versions of popular adult hits, Broadway and Hollywood show tunes.

[11] In the late 1980s, however, the audience for soft instrumental music was aging and management decided a change was needed.

[12] Central Pennsylvania already had several soft AC stations, including 101.3 WROZ and 103.3 WSBA-FM (now WARM-FM), so this format only lasted for two years.

In February 1990, the station switched its call letters to WXBB, and flipped to hot adult contemporary as B97.3.

In March 1992, WHP-AM-FM were sold to Pennsylvania Broadcasting Associates, a division of Dame Media, which separated the stations from WHP-TV.

[19] In August 1998, the Dame Media stations, including WHP and WRVV, were sold to Clear Channel Communications, the forerunner to iHeartMedia, Inc.[20][21] The format changed to classic rock after the sale.

[22] Since the mid-1990s, WRVV and WNNK frequently trade the number one spot in Nielsen Audio's Harrisburg-Lebanon-Carlisle radio market.
