Owned by Coldwater, Michigan businessman Stephen Swick, the station airs a hybrid adult contemporary/Hot AC music format branded as FM's Best.

WLKI's primary service area includes the cities of Angola, Fremont, Clear Lake, Orland, and Waterloo in Indiana, Coldwater, Bronson and Camden in Michigan, and Edon, Ohio.

Its signal reaches portions of DeKalb County, and can be heard as far away as Hudson, Michigan although reception farther east is impeded by co-channel WNIC in the Detroit area.

The WLKI airstaff includes Andy St. John in the mornings and afternoons, mid-days with Jeremy Robinson and nights with Randi Douglas.

In November, 2009, WLKI began broadcasting in HD, allowing Swick the opportunity to place two additional signals into the Angola area.
