KDGE () is a commercial radio station licensed to both Fort Worth and Dallas, Texas. It is owned and operated by iHeartMedia, and broadcasts a mainstream adult contemporary radio format, switching to Christmas music for much of November and December. The station's studios are located along Dallas Parkway in Farmers Branch, Texas (although it has a Dallas address). The transmitter site is off West Belt Line Road in Cedar Hill. KDGE broadcasts using HD Radio technology. Its HD2 digital subchannel carries an alternative rock format, known as The Edge. History Easy Listening format 102.1 FM was authorized by the Federal Communications Commission in 1960 to broadcast as KFMF, but the station was not immediately built. KJIM AM 870 (now KFJZ) purchased the KFMF construction permit and it signed on the air on April 10, 1962, as KJIM-FM. At first, KJIM-FM simulcast the daytime-only AM sister station, to allow programming to be heard after sunset. Later, KJIM-FM switched to an automated easy listening instrumental format. KJIM-AM-FM acquired a UHF-TV permit in the mid-1960s to construct Channel 21 (today KTXA). The company sold off AM 870 to raise capital. Move to Album Rock In 1966, KJIM-FM changed their call letters to KFWT-FM and improved its signal, going from 2900 watts at 165 feet to 100,000 watts at 1,000 feet HAAT from the antenna tower that would also transmit Channel 21. (Channel 21 went on the air in 1967 and signed off in 1970, returning under new ownership in 1980.) KFWT-FM was sold to Marsh Media of Amarillo, Texas and subsequently changed its call letters to KFWD. In 1973, the station flipped to album rock, and was bought by the Southern Media Company in 1975. Switch to Q102 In October 1978, new General Manager Bud Stiker led the change of the call sign to KTXQ and the branding to "Q102" (to launder the station of a Fort Worth image, and to lessen confusion with then-CBS network affiliate KDFW-TV Channel 4). In 1983, CBS Radio bought the station. Through the 1980s and 1990s, the station aired variations on the rock format, including classic rock and mainstream rock. Morning hosts Bo and Jim were popular Q102 DJs for most of Q102's existence. Though KTXQ maintained high ratings for years, by the mid-1990s, the station fell into a steep decline, particularly after the debut of KRRW's similar-sounding classic rock format.
