KDGE

KDGE (102.1 FM) is a commercial radio station dually licensed to both Fort Worth and Dallas, Texas. Star 102.1 airs an adult contemporary radio format, switching to Christmas music for much of November and December, and is owned by iHeartMedia, Inc.

The station's studios are located along Dallas Parkway in Farmers Branch, Texas (although it has a Dallas address), and its transmitter site is off West Belt Line Road in Cedar Hill. KDGE broadcasts using HD Radio technology. Its HD2 digital subchannel carries a bilingual AC format, known as "Magic".

The station was authorized by the Federal Communications Commission in 1960 to broadcast as KFMF, but it was not immediately built. KJIM (870 AM; 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.

In 1966, KJIM-FM changed their call letters to KFWT-FM and improved its signal, going from 2,900 watts at 165 feet to 100,000 watts at 1,000 feet HAAT from the antenna tower that would also transmit KFWT-TV (channel 21). (KFWT-TV went on the air in 1967 and signed off in 1970; a new station, KTXA, would reactivate channel 21 in 1980.) KFWT-FM was sold to Marsh Media of Amarillo, Texas, and subsequently changed its call letters to KFWD in 1971. In 1973, the station flipped to a Top 40 format. After two years, an album rock was put in place in January 1975.

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. In its final book in the summer of 1998, KTXQ was ranked 19th with a 2.4 share of the market.

In early 1997, CBS sold the station to New York City-based SFX Broadcasting. By August of that year, however, Austin-based Capstar merged with SFX. Six months later, locally based Chancellor Media acquired KTXQ through a series of trades with Capstar.

At Noon on August 27, 1998, on the same day that Chancellor announced that they would merge with Capstar to form AMFM, Inc., KTXQ discontinued its long-running rock format and began stunting with simulcasts of other AMFM stations from across the country (including KYLD, WHTZ, KYSR, and WUBE-FM), as well as redirecting listeners to KZPS. On August 31, at 3 pm, KTXQ flipped to rhythmic oldies as "Magic 102". The first song on "Magic" was "Shotgun" by Jr. Walker & the All Stars.

In 2000, as a condition of Clear Channel's purchase of AMFM, sister station 94.5 FM, along with the intellectual property of Magic 102, were sold to Radio One. When Radio One moved the rhythmic oldies format to 94.5 at 6 a.m. on November 9, 2000, Clear Channel moved 94.5's alternative rock format to 102.1 as KDGE, "102.1 the Edge".
