KDSN-FM & KDSN stations carry a large amount of local news and farm information, with a mix of adult contemporary and classic rock on FM and country and polka on AM. They deliver the only city-grade signals to Denison.
In September 2018, UNW Media divested the station to JC Van Ginkel, James Field, James Van Ginkel, John Van Ginkel, & Rodney Christensen's Crawford County Broadcasting. The majority owners also operate KNOD-FM, Harlan Iowa and KJAN, Atlantic Iowa.[5]
On January 14, 2020, the signal changed from 107.1 to 104.9 as planned in the transfer agreement between the current owners and UNW Media.
