KIDR is owned by En Familia, Inc. and airs a Spanish-language Roman Catholic religious radio format.

In October 1964, KUEQ acquired a troubled FM station in Phoenix, KEPI at 96.9 MHz, and relaunched it as easy listening KMEO.

From the 1960s till the early 90s, the two stations simulcast a beautiful music format, which was quite successful and lasted through several ownership changes.

In 1976, B & D Broadcasting, owned by the Beauchamp and Dodge families,[4] bought KMEO-AM-FM; the pair was sold in 1980 to Scripps-Howard Broadcasting, which owned the stations until it was required to divest them in 1985 so it could acquire KNXV-TV,[5] a decision upheld that July by the Federal Communications Commission.

[12] AM and FM programming was split for good when Bonneville relaunched KMEO-FM as "Sunny 97" KPSN on July 3, 1991; it is now KMXP.

Although the station has changed ownership and formats several times, its callsigns still refer to "Kid Radio."

During the summer of 1998, then-programming director Matt Miller would deejay an hour of contemporary dance and alternative rock music from 2-3 PM Wednesdays-Fridays, in what would be deemed "The Afternoon Fiesta".
