It airs Westwood One's Good Time Oldies format and can be heard in a very small area around Ludington and Scottville.
In February 2017, WLDN returned to the air on 98.7 FM, allowing WKLA and W224CA to resume the oldies format.
WKLA-FM spent much of its programming day simulcasting the AM signal before introducing a separate adult contemporary format around 1980, which it has retained since.
In 1996, the station was purchased by Roger Baerwolf under the corporate name of Lake Michigan Broadcasting, Inc. Until July 2012, the company owned and operated WKLA AM/FM, WMTE AM/FM (Manistee) and WKZC-FM (Scottville).
In June 2012, it was announced that Lake Michigan Broadcasting was selling all of its Ludington/Manistee stations to Synergy Media, which already owned and operated WWKR in Hart and WMLQ in Manistee.
