KDMX () is a radio station serving the Dallas/Fort Worth Metroplex in Texas. It is currently owned and operated by iHeartMedia, and airs a hot adult contemporary format. The station's studios are located along Dallas Parkway in Farmers Branch (although it has a Dallas address), and the transmitter site is in Cedar Hill. History Classical (1959-1965) This station first began its broadcasting activities as KQRO on October 15, 1960 (although license was granted on July 2, 1959). It went dark a year later then returned to the airwaves in 1962. For that time, KQRO's format consisted mostly of classical and orchestral music. Middle of the Road (1965-1971) In 1965, the callsign was changed to KEIR after being purchased by trade school Elkins Institute of Radio and Electronics. The station was used for training by Elkins with a two-room studio and transmitter located in the Life Building on Jackson Street in downtown Dallas, although the school was located near Love Field on Inwood Road. The station's Effective Radiated Power (ERP) was and was difficult to be received outside Loop 635 around Dallas. The station's format was "Middle of the Road" featuring easy listening vocal and instrumental album tracks from 11 a.m. to 11 pm. daily. The station was sold by Elkins when the school obtained a license for a non-commercial FM station in 1971. Religious (1971-1977) In 1971, the call letters were changed once again to KDTX, this time with a religious format. Six years later, the callsign was changed to KMGC (the KDTX call letters were later used on a local TV station in 1987, with Christian programming) and the Christian contemporary format continued up until September 1977. "Mellow/Magic 102.9" (1977-1991) It was then changed to an adult contemporary format as Mellow 102.9 and a month later to Magic 102.9. Prior to that, a mass distribution of door-hanger flyers announced the station is coming. "Mix 102.9" (1991-2012) The station enjoyed a loyal following until May 9, 1991, when, after Nationwide Communications bought the station, KMGC began stunting with a series of formats ranging from rock oldies (as "Cool 102.9" on May 9) to country (as "Kickin' Country" on May 10) to an all-Beatles format (also on May 10), and then party cocktail noise on May 11 and May 12, before changing to its current callsign and settling on its long-running Hot adult contemporary format as "Mix 102.9" on May 13
