KIMN (100.3 FM, "Mix 100") is a Contemporary Hit Radio radio station in Denver, Colorado. This station broadcasts at 100.3 MHz with an effective radiated power of 97 kW and is under ownership of Wilks Broadcasting, which also acquired sister stations KXKL and KWOF from CBS Radio in 2008.[1] Its studios are located in Denver and the transmitter site is on Mount Morrison west of Lakewood.


The station signed on the air on August 8, 1959 as KLIR and spent most of its life as MOR and as a beautiful music outlet. On June 7, 1984 the station switched to an Adult Contemporary format as KMJI, but would later tweak its direction to Soft AC and change its calls to KXLT. In 1992 it reclaimed the KMJI calls and evolved to an all-'70s direction in 1994. The KIMN calls were picked up in 1995. In 1997, KIMN return to AC (As "KIM 100.3"), and in 1999, the station evolve into a Hot AC format and adopt the "Mix" moniker. The weekends featured '80s' music from Def Leppard to Madonna. In summer 2014, KIMN updated its moniker to "Mix 100.3" and changed its positioning statement from "Denver's Best Music Mix" to "All The Hits" hinting at more contemporary flow of music. Mix 100.3 now no longer plays any music from before 2000.


Mix 100.3 is a CHR/Top 40 station that broadcasts a variety of music from artists like Katy Perry, Kelly Clarkson, John Mayer and OneRepublic.

The popular morning show is the family-friendly "Dom in the Morning" (formally known as "The Dom & Jane Show") featuring Dom Testa with producers Jeremy Padgett and Emily McKenzie. "Dom in the Morning" regularly rates number 1 among Denver morning shows with adults 25-54. Other station airstaff include Mark Andrew (weekdays 10am-3pm) and Bo Jaxon (weekdays 3-7pm).

In June 2008, Mix became the Denver affiliate of the syndicated show "On-Air with Ryan Seacrest" until February 2009. The station currently airs "American Top 40" hosted by Ryan Seacrest on Sunday mornings.

After some time passed by in 2014 and onto 2015, Mix 100 has shifted to more of a CHR/Top 40 sound but continues to report to both Mediabase and Billboard/BDS Adult Top 40 charts. This also makes Mix 100.3 more in competition with Entercom's CHR/Top 40 Alice 105.9 and Rhythmic Top 40 sister KS107.5, and iHeartMedia's CHR-leaning Rhythmic Top 40 95.7 The Party.

HD Channels[edit]

Mix also provides listeners with two HD subchannel stations: 100.3-HD2 features "Ultimate 80's Mix" and 100.3-HD3 plays Jazz favorites.[2]


The call letters KIMN, originally belonged to a Denver AM station located at 950kHz. From the late 1950s to the 1980s KIMN was the dominant Top 40 music station in Denver. The station also highlighted the popular local rock n' roll bands of that era, such as the Astronauts, Daniels, Fogcutters, Moonrakers, Soul Survivors,and others.[3] The station had other nicknames as the Denver Tiger, Boss Radio, and 95 Fabulous KIMN.[4] The station was then owned and operated by the late Kenneth E.
