FROM THE TIMELINE
Moments in KNRX-FM History
KYBG flips to modern rock as KNRX 92-X
On March 29, 1995, KYBG 92.1 flipped to modern rock and became KNRX, 92-X. The alternative format lasted less than a year before the station's dramatic 1996 switch to JAM'N 92.1.
KNRX 92.1 becomes JAM’N 92.1 and raids KS104
At 8 p.m. on February 29, 1996, modern-rock KNRX 92.1 flipped to rhythmic contemporary as KJMN, JAM'N 92.1. The launch was especially notable because the new station recruited much of the competing KS104 air staff, escalating one of Denver radio's most memorable format battles.
EXCL Communications acquires 92.1
In January 1997, EXCL Communications, later part of Entravision, acquired 92.1 FM. The purchase set up the end of JAM'N and the launch of Spanish-language programming on the frequency.
JAM’N 92.1 ends and Radio Romántica launches
On March 30, 1997, JAM'N 92.1 ended its rhythmic format after EXCL Communications acquired the station. The frequency became Spanish adult contemporary Radio Romántica 92.1, described in station histories as Denver's first Spanish-language FM outlet.
