KTMG  KTMG (99.1 FM, "Magic 99.1") is an American commercial adult contemporary music radio station in Prescott, Arizona, broadcasting to the Prescott, Arizona, area. An FM translator relays the KTMG HD2 signal, known as Fun Oldies 97.9. KNOT-FM signed on 98.3 MHz in 1978 after a multi-year fight between Parkell Broadcasting, which built the station, and Southwest Broadcasting Company, which sought to have it denied. Payne-Prescott Broadcasting Company bought KNOT-FM in 1981 and moved it to 99.1 in 1993.
