The 92.1 FM lineage began in 1979 as country KMJD and moved through a rapid succession of Denver-market identities: adult contemporary KRKY, jazz KADX, rock KZRZ, country/talk KYBG and modern-rock KNRX “92-X.”
On February 29, 1996 at 8 p.m., KNRX became KJMN “JAM’N 92.1.” The launch was particularly disruptive because KJMN recruited much of the air staff from rhythmic competitor KS104/KQKS. The JAM’N lineup included Mark & Laurie/Mark & Mercedes in mornings, Brandon Scott, Michael Hayes, Sweet G and Ed Atkins.
EXCL Communications acquired 92.1 in 1997. On March 30 it ended JAM’N and launched Spanish AC Radio Romántica, making 92.1 Denver’s first Spanish-language FM outlet. The station later used Super Estrella, José and La Suavecita branding while retaining the KJMN calls.
