WKFN (540 AM, "The Fan") is a radio station broadcasting a sports format. It is an affiliate of ESPN Radio. The station is licensed to Clarksville, Tennessee. The station is currently owned by Saga Communications. Saga Communications also operates WVVR 100.3 Country, WRND-FM 94.3 Classic Hits, WCVQ 107.9 Adult Contemporary, and WZZP 97.5 FM Active Rock from its main offices in Clarksville.
The network was operated by Aaron B. Robinson. Upon his death in 1961, the stations were held in trust by a bank in Jackson which was to decide if Aaron Robinson, Jr. should inherit them. The bank eventually deemed that he should not and the stations all were sold, and the operations of the network wound up, in 1973.
The Dixie Radio Network had six stations, three of which had call letters which contained the letters WDX: WDXE Lawrenceburg and WDXI Jackson were sister stations to WDXN. All these stations were primarily "daytimers" until 1986 when deregulation allowed broadcasting past sundown, but then began broadcasting 24 hours a day.
At one time WDXN was owned by Jack Mayer of Clarksville, who was the long-time secretary of the Tennessee Association of Broadcasters.
