(Max Radio of Denver LLC)
The station was originally KKDD, licensed to Brush, Colorado with an easy listening format. Its call sign changed to KSIR on July 1, 1991. On March 20, 2006, as the station was being relocated to Denver, its call sign changed to KSYY-FM to stand for "Sassy 107" and its soft adult contemporary format. This lasted until February 7, 2008, when it flipped to Top 40 as "One FM". On February 29, 2008, its call sign changed to KONN. At first, the station was billing their direction as "Rhythm-based hit music," but in actuality, has moved into a more mainstream Top 40/CHR approach since the format flip.
HOT 107 as KDHT
On December 15, 2009, KONN changed its call letters to KDHT to better reflect its current branding.
The KDHT call letters were on another Denver station in 1993 on 92.5, which is now KWOF, before being dropped and picked up by Emmis Communications for their station in Austin, Texas on 93.3 FM (now KGSR).
Dance returns as Hot 107
On March 30, 2012, KDHT flipped to a Dance music format while keeping the same moniker and airstaff in place. The format and playlist consisted mostly of current Dance, Electronica, and remixed Rhythmic/Pop hits.
Dance gives way to Jack FM
On November 30, 2012, at 3 PM, after playing "Unforgivable" by Armin Van Buuren, the station began stunting with marijuana-themed music (in reference to the recent legalization of personal marijuana usage in Colorado), branded as "Pot 107.1." The first song on the "Pot" stunting was "Rocky Mountain High" by John Denver. The stunt lasted until 3 PM the following Monday, when, after playing "Smoke on the Water" by Deep Purple, "Jack FM" returned to Denver with "a bunch of songs in a row", with "What I Like About You" by The Romantics being the first song played. This marks the second time the format/moniker was used in the Denver market, the first time being on KJAC (105.5) from April 2004 until September 2012, when it flipped to ESPN Radio.
Jack becomes 107X
On March 24, 2014, KDHT changed their format to alternative rock, branded as "107X", launching with 5,000 songs in a row through April 7th of that year. The first song on "107X" was "Anarchy in the U.K." by The Sex Pistols. On March 27, 2014, KDHT changed their call letters to KXDE to go with the "107X" branding. Likely due to the station's rimshot signal, the format never could compete against iHeartMedia's KTCL and KBPI, registering just a 0.4 share in the December 2014 Nielsen Audio PPM ratings.
107X goes Fly
On December 24, 2014, at 3 PM, just 9 months after flipping to "X", KXDE flipped to classic hip-hop, branded as "Fly 107-1", launching with 15,000 songs in a row, nonstop through "Jamuary" 31st.  The final song on "X" was "Man in the Box" by Alice in Chains, while the first song on "Fly" was "Disco Inferno" by 50 Cent.
