JAMN’ 92.1 was a great-sounding but short-lived Rhythmic CHR station.
According to the KJMN and KQKS Wikipedia pages, JAMN’ 92.1 debuted in March 1996 and lured away all/most of the airstaff (and even at least one promotion, as heard on the aircheck) from KQKS (which at the time broadcast on 104.3 under the name “KS104”).
In November of that year, Western Cities (owner of KQKS) sold the station to Jefferson-Pilot, which also owned Mainstream CHR KHHT “K-Hits 107.5” — a station with a much more powerful signal than 104.3 (and 92.1). In February 1997, KQKS and its Rhythmic CHR format moved to 107.5 under the name “KS107.5”. An aircheck of KS107.5, recorded not long after its debut, is also available on this site.
One month later, JAMN’ 92.1 (which itself had been sold to EXCL Communications, later Entravision) threw in the towel and became Denver’s first Spanish-language FM station.
During this aircheck, KJMN was broadcasting live from the Billboard Music Awards, which was taking place in Las Vegas that year. Included are interviews with the Isley Brothers and Bone Thugs n Harmony.
