KJMN (92.1 FM) is a radio station broadcasting a Spanish adult hits format licensed to Castle Rock, Colorado, USA, serving the Denver-Boulder area. The station is currently owned by Entravision Holdings, LLC.[2][3] Its studios are located in Denver near Sports Authority Field at Mile High, and the transmitter is west of Castle Rock.


KJMN signed on the air in 1979 as adult contemporary KMJD, but would go through various formats and call letters as rock outlets KRKY (1983–84), KADX (1984–88) and KZRZ (1988–89), country KYBG (1989–95), and modern rock KNRX (1995–96).[4]


During the KNRX stretch, 92.1 was called "92-X," and catered to the modern rock and alternative rock listeners. One DJ was known as Malcolm, and he spoke in a low monotone.

KJMN/Jam'n 92-1[edit]

On February 29, 1996, at 8:00 PM, KNRX shook up the market by luring the airstaffers away from Rhythmic Top 40 KQKS (then known as KS104.3) and launched KJMN "JAM'N 92.1". During its Rhythmic tenure, they would attack KQKS on air and on the streets, but the tactics would backfire the following November when KQKS was sold to Jefferson-Pilot, who would later shake up the airwaves in February 1997 by moving KQKS to 107.5 and quickly reclaimed their listeners and ratings.

Excel purchases 92.1[edit]

After EXCL Communications (later Entravision) acquired the station in January 1997, they pulled the plug on "JAM'N 92.1" that March 30 to bring Denver its first Spanish FM outlet, launching Spanish AC "Radio Romántica 92.1", but kept the KJMN calls. However, by 2004 they would flip to Entravision's Spanish Top 40 "Super Estrella" format. The station is currently a "satellite" repeater station programmed out of Los Angeles, California, running local Denver advertising. No original programming is done in Denver.

In January 2009, KJMN switched formats from Super Estrella's Spanish AC format to the Jose Spanish adult hits Format.[5]
