WBYN-FM (107.5 FM) is a Christian radio station licensed to Boyertown, Pennsylvania and serves the Reading area.

On September 14, 1989, the station was sold and changed the call sign to WYCL and flipped to a gold based down-tempo Adult Contemporary music format.

Artists included The Beatles, Billy Joel, Kenny Rogers, Whitney Houston, Gloria Estefan, Chicago, Supremes, Elton John, The Stylistics, George Michael, and others.

Ken And Jenn in the morning, Randi Ellis middays (also PD/MD), Brian DiMario in afternoons, former Y100 100.3FM Philadelphia jock John Von (who also served as Frank FM production director) at night, and Mike Roberts.

The station started off as a hybrid of Hot AC, Classic Hits and Pop Alternative playing over 200 songs.

By the end of 2006, the station evolved into more of a heavily rock leaning classic hits format, including songs up until 1995.

Core artists included Billy Joel, Kansas, Phil Collins, The Beatles, Elton John, Led Zeppelin, Fleetwood Mac, Chicago, Boston, Eagles, James Taylor, The Who, Neil Young, Kenny Loggins, The Cars, and many others.

On March 31, 2009, the LMA between Nassau and WDAC-FM (owners of the license of WFKB) expired after being extended several times since November 2008 and the station's call sign reverted to WBYN-FM.
