KDGE (102.1 FM) is an iHeartMedia adult contemporary commercial radio station dually licensed to both Fort Worth and Dallas, Texas.

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).

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.

[3] 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.

[7][8][9] 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.

Soon after debuting KDGE, Allison then immediately took on the construction of a 2,000-foot tower in Collinsville, Texas to improve the station's signal.

Wendy Naylor, who had worked for Allison at his various stations in Phoenix since 1982, was chosen as the music director and morning show co-host along with KEYX alumni Roger King.

Also relocating to Dallas from Phoenix was Tom Duran as the Sales Manager and a major player in helping create The EDGE's promotion and concerts.

A collaborative effort by the Allisons, Duran, Neilson, Wendy Naylor and George Gimarc was the driving force in making The Edge a player in the Dallas market.

Several later issues were double-CD compilations, with one CD featuring current local bands, and the other being more specialized, including one focused on the area's earliest punk bands, including tracks by The Nervebreakers, The Telefones, Stickmen With Rayguns, and The Hugh Beaumont Experience, while another, put together by DJ Jeff K, featuring the (then-)newer styles of dance-club music including techno, trance and electropop (a direction the station was increasingly taking in 1994–95, after the departure of Gimarc, and with the increasing prominence of Jeff K).

Past Edgefest acts included Pearl Jam, The Charlatans, Sugarcubes, Tripping Daisy, Seether, The Origin, Nickelback, Staind, My Chemical Romance, Muse, The Killers, Placebo, Kaiser Chiefs, Weezer, The Toadies, Blue October, INXS, Beck, Social Distortion, Everclear, Sponge, The Mighty Mighty Bosstones, Default, KoRn, Deftones, Hole, Phoenix, The Black Keys, Cage the Elephant, Cake, Flogging Molly and Drowning Pool.

Other notable jocks during this time include Alex Luke, Brian the Butler, Jerry Lentz, Roger King, Ernie Mills, Jeff K, Josh Venable, DJ Merritt, and Valerie Knight.

In 1994, Steve Allison sold KDGE for $16 million to the broadcast-arm of the Church of Jesus Christ of Latter-day Saints, which also owned classic rock station KZPS.

The station's 'unofficial' 20th Anniversary party was on July 3, 2009, at the Lakewood Theatre with performances from Zac Malloy of the Nixons, John Easdale of Dramarama, Deep Blue Something, Pop Poppins, and the Bat Mastersons.

In April 29, 2010, The Billy Madison Show left KDGE and moved back to Tulsa, Oklahoma’s radio station KHTT.

On November 16, 2016, at 3 pm, after playing "Out of My League" by Fitz and the Tantrums, KDGE began stunting with a continuous loop of "Closing Time" by Semisonic (for the first few hours, it was interspersed with "It's the End of the World as We Know It (And I Feel Fine)" by R.E.M.

This makes Delilah's return to the Dallas/Fort Worth market since being dropped by longtime affiliate KVIL in January 2014 during its gradual evolution to CHR/Top 40.

[14] KDGE's HD2 channel originally broadcast "The Cutting Edge" a version of the station's alternative rock format with reduced commercials and some tracks never before played on the radio.
