Playing country and MOR since its inception in 1974, the original call sign was KIEE until they were assigned KCFX on December 21, 1983. They played album rock until developing the current Fox format (101 the Fox) in 1985, when they became the first classic rock station in a major market in the country. In 1990, they swapped frequencies with KMZU in Carrollton, jumping from 100.7 MHz to 101.1. They played a blend of artists from the late 1960s, 1970s, and 1980s. In recent years they have started playing some hits from the 1990s by artists like Bruce Springsteen and Scorpions, as well as Collective Soul, Stone Temple Pilots, and Metallica, among others. This comes after years of billing themselves as only playing 1970s rock with some 1960s and 1980s. As the years wore on they added more 1980s. Some of the artists they air are The Beatles, Eric Clapton, The Doors, Cheap Trick, Night Ranger, Inxs, Jimi Hendrix, Fleetwood Mac, Led Zeppelin, Queen, The Cars, The Police, Heart, Yes, Emerson, Lake & Palmer, Poison, and Creedence Clearwater Revival among many others. The Fox, since 1990 NFL season, is the flagship station for the Kansas City Chiefs of the National Football League. It is believed to be the first FM music station to carry an NFL team's play-by-play. The station carried The Bob & Tom Show from March 13, 2006 to February 9, 2007 as its morning drive program. A new local morning show featuring former KYYS voices Larry Moffit and Frankie (formerly middays) replaced that show. On January 11, 2008, longtime rival rocker KYYS changed formats (and call letters to KBLV), prompting KCFX to change its slogan to "Kansas City's Only Classic Rock Station." In October 2008, Cumulus Media had massive layoffs to its stations across the country. Among those released were KCFX morning team Moffit and Frankie. In March 2009, Slacker, longtime heritage (KY102 & 997KY) Classic Rock DJ from Kansas City, was installed as the KCFX morning show weekdays from 5am to 9am. The Slacker Morning Show has proved to be the must successful and longest running of all previous morning teams.
Program Director Chris Hoffman took over at middays from 9am to 2pm, and longtime heritage Classic Rock DJ Skid Roadie aired on the drive home evenings from 2pm to 7pm. In 2013, Dan McClintock replaced Chris Hoffman as Program Director.
