OUR HISTORY

Tunwall Radio is connected to the earliest days of radio. Steve Tunwall’s grandfather, Carl Tunwall, Sr., owned and operated radio station KFJY in Fort Dodge, Iowa. Broadcasting at 1220AM, it was one of the first stations in the state, receiving its license from the FCC in 1924. Tunwall Radio Corp. also owned and operated a radio store and repair shop in Fort Dodge. Tunwall Radio LLC, a Florida limited liability corporation, has no business connection to the original Iowa company. We do use a variation of the original company logo as our own today. We also proudly display photos of the 1920s era Tunwall Radio service car, a Ford Model T, in our company literature and here on tunwallradio.com.
