WFDL (AM)

The station was reassigned the call letters WLKE on January 9, 1984 and simulcast a country music format with WLKE-FM (99.3 FM).

And on October 14, 2002, the call letters changed again to the current WFDL[4] which aired ABC/Citadel's Timeless Favorites until that satellite format ended on February 15, 2010.

On February 16, 2010, WFDL began airing "Hit Parade Radio" in certain day-parts.

However the signal does not reach far outside of Waupun; to solve this issue, a second translator on 93.7 FM signed on in late August 2018.

[5] On November 19, 2019, the station rebranded as "The Source", and began carrying The True Oldies Channel in time periods not occupied by local programming.
