History.
WJJK started as WAJC (with the call letters standing for Arthur Jordan College of Music) on September 25, 1950. It originally signed on at 91.3 MHz, moving to its current frequency of 104.5 MHz in 1956. It was the Butler University radio station. In 1993, it was sold to Susquehanna Radio Corporation—which has since been purchased by Cumulus Media Partners. It then changed its call letters to WGRL and adopted a country music format. The call letters were changed to WGLD in 1997 when the station adopted an oldies format as "Gold 104.5." In 2005, WGLD became WJJK, dropping oldies and subscribing to the Jack FM adult hits format. The station became known as "104.5 Jack FM." In September 2006, WJJK became a "classic hits" station, while keeping the same call letters. The name "Jack" was dropped in December 2007 and it is now known as "Classic Hits 104.5 WJJK."
