KOAZ broadcasts a smooth jazz music format branded as "103-7 The Oasis" which was launched at noon on Valentine's Day (February 14), 2012.

It was owned by the Paulino Bernal Evangelism and aired its "Radio Christiana" Spanish-language ministry from its main station KCZO in Carrizo Springs, Texas from about 1999 until the late 2000s at just 10 watts.

91.1 is part of the non-commercial section of the FM band, so it was moved to 103.7 in early 2012 to broadcast a commercial format as well as increase power to 250 watts from atop Sandia Crest, giving the station a strong signal across Albuquerque.

American General Media had briefly run a smooth jazz format on KBOM-FM 94.7 in Santa Fe in 2004-2005, a few months after KAJZ moved to 101.7 which only covers Albuquerque.

In April 2005, Clear Channel Communications (now iHeartMedia) launched a smooth jazz station for the Santa Fe market on KSFQ (now KSFR) 101.1 FM, branded as "The Cat".

However, in December 2007, Clear Channel did a frequency swap with modern rock station KTEG, moving it to 104.1 and the smooth jazz format on KABQ-FM to the weaker 104.7 signal.

On September 1, 2020 KOAZ was dropped from KSFE and K240EC and was replaced by the Regional Mexican programming from sister station KDLW "La Zeta" 106.3.
