Originally the station served Emporia, Kansas at 92.7 mHz. The earliest call letters are KZOC, first assigned in 1981. KZOC went on the air July 26, 1982 as a country station. KZOC later referred to itself as "KZ93." The station moved to 92.9 mHz and upgraded power to 36,000 watts in 1989.

C&C Consulting bought the station in 1994. The format changed to oldies, fed from ABC's network of satellite formats. C&C downgraded the transmitter to 7,900 watts in 2000. The station still targeted Emporia, but began to gravitate toward the Topeka market around the turn of the century.

Topeka had never had an urban-formatted station before. But, it happened in 2003 after a sale of KANS to 3 Point Communications. The "Wild 92.9" format began with a stunt, a continuous loop of Tone Loc's "Wild Thing." Despite the new owners using the same playlist for several months, the station actually did well in the ratings. But it wasn't selling much commercial time either. I don't recall the station ever being anything other than automated. KKYD ran the syndicated "Playhouse" morning show for a year.

Using the name Viking Media, and later becoming Great Plains Media, Jerome Zimmer bought the station in 2005. On July 21, 2005, Zimmer brought a "Jack FM"-style format to this frequency to avoid any overlap with CHR-formatted KLZR. The call letters eventually changed to KMXN. "Max FM" never had jocks. The station's playlist was generally hits of the 1970s and 1980s. Great Plains Media upgraded the wattage to 42,000 watts, moving the transmitter again-- closer to Lawrence.

On February 27, 2006, With "Max" not doing so well, KMXN flipped to a classic rock format to compete more directly against KDVV and KWIC. KMXN added live air talent, plus the syndicated Bob & Tom show. During this time, KMXN started to carry Free State High School sports.

In January 2007, "X" transitioned from classic rock to a more current-based hard rock. The station progressively targeted Lawrence beginning in this time period. They went through a couple of different syndicated morning shows during this time, the second one a Michigan-based show called "Free Beer And Hot Wings."

In October of 2009, KMXN stunted for a few days with television theme songs. On October 8, KMXN flipped to country as "92.9 the Bull." The station signed up the syndicated Big D & Bubba show for mornings, and a Taste of Country Nights to fill the evening slot. The flip made the station the fourth country station in the Topeka area, all with different owners. KOFO in Ottawa simulcasted in 92.9's HD2 channel from 2011 to 2013. As of today, the lineup remains mostly syndicated.
