History
KPHO at 1200/1230
From sign-on in October 1940 to March 1941, KPHO occupied 1200 kHz. On March 28, 1941, KPHO and all other stations on 1200 moved to 1230, when the North American Regional Broadcasting Agreement (NARBA) took effect. Beginning in 1944, the station carried the dramas, comedies, news and sports of the Blue Network, which later became ABC; previously, both NBC Red and NBC Blue network programs aired on KTAR (620 AM). On September 21, 1949, KPHO moved to 910 kHz, which was later the home of KJJJ and KFYI and is now KGME with sports talk.
KRIZ
The move of KPHO to 1230 created an opening for a new local station to use its facilities and frequency. Howard M. Loeb filed on September 23, 1949, for a new radio station on 1230 kHz in Phoenix; the proposed station would use KPHO's former plant at 24th Avenue and Buckeye Road, which Loeb had purchased.

Why this record matters
“KOY” is worth following because a concise public description often conceals a longer documentary argument. Here, regional, Mexican and radio provides the most credible route into that argument.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Aug 24, 2026. The linked authority identifier is Q6335344. Authority coordinates are 33.436, -112.109. 3 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1230, 1200, 1940 and 1941.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
