It is locally owned by the Marques brothers and operates a regional Mexican music format under the branding "La Mejor".
The station was co-owned by Ira Lavin and actor Dick Van Dyke (an Arizona resident).
[5] Van Dyke and Lavin sold KXIV in 1982 to local real estate developer Michael Levin, who relaunched the station with a news/talk format as KSUN, featuring personalities from ABC's TalkRadio Network, NBC's Talknet and audio from CNN2.
[6] The call letters had been sold to Levin by the previous KSUN in Bisbee, at the time silent and in receivership.
[11] By 1986, KSUN was running jazz full-time with minor league baseball play-by-play of the Phoenix Firebirds, having lost Radio AAHS when Children's Radio Network opted to cease distributing it outside of its owned-and-operated stations.
