WRUF (850 kHz) is an AM radio station that operates from the University of Florida's main campus in Gainesville, broadcasting at 850 kHz. WRUF is a sports station that covers University of Florida athletics. Unlike its public sister stations, WUFT TV and WUFT-FM, WRUF is a commercial station and, despite being state-run, is run no differently from privately owned commercial stations. The station signed on in October 1928 and is the fifth-oldest station in the state.
