The station's studios are on Vartan Way in Harrisburg,[2] with its transmitter atop Blue Mountain in East Pennsboro Township.

The station signed on for the first time in 1962 as WTPA-FM under ownership of Newhouse Broadcasting, owner of WTPA-TV (today's WHTM-TV) with a beautiful music format.

[6] AMFM was then itself purchased by Clear Channel Communications (now iHeartMedia) in a deal announced on October 3, 1999, and valued at $17.4 billion.

[8] In 2001, shortly after the ownership changes, Clear Channel launched WHKF in an attempt to reduce Wink 104's market dominance by stealing the younger portion of WNNK's audience.

On August 31, Cumulus Media announced that W237DE would begin simulcasting WHGB the next day, on September 1, bringing ESPN Radio programming to 95.3.

[12] WNNK-FM is short-spaced to WAEB-FM B104 (licensed to serve Allentown, Pennsylvania) as they both operate on the same channel and the distance between the stations' transmitters is 76 miles (122 km) as determined by FCC rules.

[13] The minimum distance between two Class B stations operating on the same channel according to current FCC rules is 150 miles (240 km).
