History
Early years
What is now KMJK started broadcasting on September 11, 1969 at 106.3 FM as KLEX-FM.
[ Broadcasting Yearbook 1977 page C-122. Retrieved May 12, 2025.] The
call sign represented the original city of license, Lexington, Missouri. The tower was just north of Odessa, Missouri. The format was
country music. The station's call letters changed to KBEK-FM in 1976, and relocated to 107.3 in 1981 with a class C signal. The station was locally owned by Lexington Broadcasters until being sold in September 1989.
In 1984, the station changed formats to satellite-fed adult contemporary music as KCAC. On December 1, 1988, the station flipped back to country music and changed its call sign to KCFM. The station was acquired by Meyer Communications in September 1989.
Top 40 KXXR and KISF
KCFM swapped formats and frequencies with Capitol Broadcasting's KXXR on February 16, 1992 at midnight. (KXXR was a Top 40 station at 106.5 FM, now
WDAF-FM.) The first song played after the swap was "I'm Too Sexy" by Right Said Fred. Meyer continued to own the station, while being operated by Capitol via an local marketing agreement (LMA).
["KXXR will move down, not off, the dial", The Kansas City Star, February 8, 1992.][ Radio and Records 1992 americanradiohistory.com] The KXXR call letters officially moved to 107.3 FM on March 13, 1992. (106.5, meanwhile, adopted the KKCJ call letters four days earlier.) US Radio, led by
Philadelphia attorney Ragan Henry who owned other radio stations across the country, bought the station in October 1992.

On February 4, 1993, after 24 hours of stunting with a loop of "Kiss" by Prince, the station changed call letters to KISF, becoming "Kiss 107.3".["KXXR, now KISF, goes to Top 40", The Kansas City Star, February 5, 1993.][ Radio and Records 1993 americanradiohistory.com] After KBEQ's unannounced flip to Country later that month, KISF became the only Top 40 station in the Kansas City market. That changed when KMXV flipped from hot adult contemporary to Top 40 in March 1994. In addition, KMXV had a signal that covered the entire Kansas City metro. Despite KISF lacking full-market coverage, the station still received decent ratings.[ Ratings Directories 1993 worldradiohistory.com][ Ratings Directories 1994 worldradiohistory.com][ Ratings Directories 1995 worldradiohistory.com]
Modern rock
During the mid-1990s,
alternative rock was becoming the popular sound of the decade, while the Top 40 format was entering a period of decline. Management decided to follow the trend and compete against Lawrence, Kansas-based
KKSW, which was seeing success with the format. KISF started evolving towards
modern rock with a lean on 1980s new wave in late 1994. The shift was complete by January 1995, including a slight name change to "107.3 Kiss FM." (The station would later rebrand as simply "107.3".)
[Brian McTavish, "KISF-FM bumps urban sounds for a 'new rock' format", The Kansas City Star, January 20, 1995.][ Radio and Records 1995 americanradiohistory.com]
With the new format, the station initially had trouble gaining an audience, due in part because the station hung on to remnants of its former format, including imaging and presentation.[ Ratings Directories 1996 worldradiohistory.com] In addition, the station shifted through several morning shows.[Brian McTavish, "Another laugh-a-minute morning show? Not on KISF", The Kansas City Star, February 24, 1995.][Brian McTavish, "FM station wakes up and smells the competitive coffee", The Kansas City Star, September 29, 1995.] Due to US Radio's financing balloon bank note becoming due, Henry was forced to sell his 49-station empire, with KISF being bought by Metropolitan Radio Group in April 1996. Syncom bought the station in May 1997.
The station rebranded as "107.3 The X" on March 16, 1997, and took the new call sign KCCX on June 25 of that year.[ Radio and Records 1997 americanradiohistory.com] Classic rock station KCFX nearly threatened to sue the station because the call letters were too similar.[Brian McTavish, "X marks the lawsuit as station sues over call letters", The Kansas City Star, September 19, 1997.] To remedy this, the call letters were changed to KNRX on March 1, 1998. During this time, the station started leaning towards the active rock route by playing harder-edged rock acts, in order to compete with KQRC. The station's airstaff during this period included Kansas City-native Mancow Muller syndicated from Chicago. Mancow began airing in mornings on March 14, 1997. Other disc jockey included Jason Justice, "The Morning (and later, Afternoon) Headrush" with Jay Charles and Sammye Phelps, and Roach and Sumo (with The Fonz) hosting "The Midnight Moshpit". Specialty programming included "Off the Beaten Track" featuring a freeform format on Friday (and later, Sunday) nights, "Resurrection Sunday" and the syndicated "Out of Order Countdown" with Jed the Fish on weekends.[Brian McTavish, "The king of all Kansas City?", The Kansas City Star, March 14, 1997.][Brian McTavish, "Honest or vulgar? Mancow's debut at least entertaining", The Kansas City Star, March 21, 1997.]
Likely because of the station's signal issues, and being one of two modern rock stations covering the Kansas City market, in addition to KKSW, the station's ratings were only modest during this time, usually in the mid-2 shares (12+).[ Ratings Directories 1997 worldradiohistory.com] By the Fall of 1997, the station's ratings plummeted to 15th place with a 1.5 share (12+).[ Ratings Directories 1998 worldradiohistory.com][ Ratings Directories 1999 worldradiohistory.com] Mancow's show was dropped on November 20, 1998.[Hearne Christopher, Jr., "Radio station expunges itself of Mancow for now", The Kansas City Star, November 23, 1998.][Hearne Christopher, Jr., "Mancow is out standing in local radio station's pasture", The Kansas City Star, November 27, 1998.]
Urban oldies
At 10:04 a.m. on January 5, 1999, without warning, KNRX dropped the modern rock format. Jason Justice played the final song on "The X", which was the acoustic version of "Plush" by Stone Temple Pilots. The station then began stunting with a ticking clock and a loop of "1999" by Prince. (On the same day, rival
KCKC dropped its
modern AC format.)
The following day at noon, KNRX flipped formats to urban oldies as "K-107, The Rhythm & Soul of Kansas City".[Hearne Christopher, "Round and round KC radio stations' formats", The Kansas City Star, January 6, 1999.][ Radio and Records 1999 americanradiohistory.com][Jeff Douglas, "KC radio scene left with...no alternatives", The Kansas City Star, February 5, 1999.] K-107's first song was "Celebration" by Kool and The Gang.["Joyner comes to KC", The Kansas City Star, January 18, 1999.] The station's ratings began to improve after the flip. In the summer of 1999, "K-107" peaked at a 3.6 share (12+).[ Ratings Directories 1999 worldradiohistory.com][ Ratings Directories 2000 worldradiohistory.com]
Urban AC
On February 1, 2001, the station's call letters changed to the current KMJK. During the summer of that year, the station moved towards an urban adult contemporary format with the new moniker "Majik 107.3". In October 2003, Cumulus Media purchased KMJK along with Radio 2000-owned
KCHZ. In the Summer of 2004, KMJK altered its moniker to "Magic 107.3". In 2008, the station changed its city of license to North Kansas City, Missouri. The station also had an
FCC construction permit to move its transmitter from Odessa to a site near Levasy, Missouri.
In 2011, with Cumulus Media's acquisition of Citadel Media, Cumulus announced that KMJK would be spun off and put into a trust called Volt Media, LLC, in order to meet FCC mandates on ownership limitations. This was despite Citadel not owning any stations in Kansas City. However, in October of the same year, Cumulus announced plans to reacquire the station.
Over the course of 2018, KMJK began dropping most classic soul and pre-1990s music from the playlist, and began adding more hip hop tracks, in order to better compete against KPRS. During the fall of 2019, the station also dropped the "Magic" moniker, rebranding to "107.3 KC's R&B and Hip Hop", and switching mostly from urban AC to mainstream urban contemporary. By 2023, KMJK’s playlist focused primarily on 1990s to current R&B, along with some classic and current hip hop songs.
Top 40 The Vibe
On September 28, 2023, at 4 p.m., after playing "End of the Road" by Boyz II Men, KMJK’s urban contemporary format moved to sister station
KCJK, which rebranded as "Power 105.1". With the move, the R&B lean was dropped in favor of the inclusion of more hip hop songs. In addition,
The D.L. Hughley Show was dropped from afternoons, as well as the weekday evening
slow jam program
107.3 After Dark. Both KCJK and KMJK simulcasted until midnight on October 6; at that time, after playing "Turn Yo Clic Up" by
Quavo and Future and a short commercial break, KMJK assumed KCHZ's Top 40/CHR format as "107.3 The Vibe". Both KMJK and KCHZ simulcasted until after midnight on October 12, when KCHZ flipped to a simulcast of KCMO’s
talk radio format.

In 1977, KMJK Magic 107 first went on the air from Lake Oswego, Oregon on 106.7 MHz (now KLTH, another set of call letters used by a Kansas City radio station (KZPT)). The station was owned by Communico Northwest Corp. (Frederic W. Constant and partners) with studios located in "Magic Manor" (the historic 1905 "Tug Master's House" at 107 Burnham Road). The Magic 107 format was an early version of what has evolved into AAA (Triple-A), Adult-Album-Alternative. Programmed by morning host Archer, the Progressive, Soft-Album Rock station developed a small but solid 18- to 34-year-old audience. KMJK enjoyed moderate, low-budget success while competing with then-KVAN 1480 AM (The Mono Maniacs) and dominant market leaders KINK and KGON. In 1979, after formally adopting dual city of license (Lake Oswego-Portland), Magic 107 was purchased by Harte-Hanks Southern Communications, Inc. and became The Magic FM. The format changed to Contemporary Hit Radio (CHR) with a semi-highbrow, semi-comedic air staff of successful, medium/major market programmers and veteran air personalities. The debut air staff included: Beau Rafferty (6–10a); John Shomby, Program Director (10a–Noon); Dave McKay (Noon–3p); Pat Clarke (3–6p); "Dancin'" Danny Wright (6–10p); Chaz Kelly (10p–2a); "Allen Wesley" Archer (2–6a). Archer, along with News Director John David Lloyd, transitioned to the new ownership and format along with Randy Scott and "Spacey" Dave Vincent.
