[2] On December 5, 1945, the Federal Communications Commission granted Peoples Broadcasting Company a construction permit for a new station on 92.3 MHz.

[3] The station went through several changes in transmitter location, effective radiated power (ERP) and antenna height above average terrain (HAAT) by the time its first license was granted on April 14, 1952.

On March 20, 1980, the station was granted a construction permit to relocate the transmitter to its current location in West Hempfield Township, Lancaster County.

New GM/VP Chuck Lontine, with the help of Scott Shannon (then the program director of WPLJ in New York City), created "The New Sound of FM 97 WLAN" in September 1993.

[4][5] In April 2018, in response to Cumulus Media moving WWKL to 106.7 (expanding the station's CHR format to cover Lancaster, York, and Reading), iHeartMedia began redirecting WHKF listeners to WLAN-FM to add Harrisburg to its scope.
