[5] In February 1990, KLSK would be sold to Progressive Broadcasting co-owned by programmer John Sebastian for $2 million.

The classic rock format on 104.1 ended in late June 2002, and was moved to 98.1 FM in Santa Fe.

Clear Channel had attempted to do Adult Album Alternative on this frequency when they had moved Santa Fe's KBAC to 104.1 in 2002.

That station started out with an eclectic format, but attempts to make changes came at the protest of Santa Fe listeners which would result in KBAC moving back to Santa Fe and a more mainstream version of AAA called "World Class Rock" would launch on 104.1 under the new callsign KABQ-FM in late 2003, only to generate similar results.

From 1986 until August 2013, programming on 104.1 was also heard in Albuquerque on translator K265CA (100.9 FM), which had broadcast at 50 watts from atop Sandia Crest.

Reasons cited on air for the frequency swap are the stronger signal in the Albuquerque market and the Santa Fe, New Mexico, area.

KTEG launched in October 1994 on the 107.9 frequency (the upper edge of the commercial FM band) with an Alternative rock format that was reaching its peak popularity at that time.

It was also active in the local live music scene, bringing more all-ages shows to town, but particularly with its annual "Edgefest" that began in summer 1995.

By the end of the 1990s, KTEG's format had started to shift from anything labeled 'alternative rock' to harder music due to changing trends in modern rock radio at the time, as well as to differentiate from its sister station KPEK, which had a modern adult contemporary format whose playlist at the time was featuring many of the same titles and artists as KTEG.

April 2009 brought many changes to "The Edge", with the loss of midday jock Ralphie, evening jock Sloppy Joe (who voicetracked from California) and all local weekend air staff in favor of national programming from Premium Choice's "The Alternative Project".

At the same time, The Edge made a substantial change in the station's programming, going from playing "harder" music, like Slipknot, Korn, and Metallica to contemporary pop artists like Mumford and Sons, Kings Of Leon, Foo Fighters and many 1990s acts, such as Bush, The Toadies, and The Offspring.
