I was listening to the stream for a bit, and when I heard the TOH legal ID, am almost certain that it foretells the future of KAHM. Along with the primary 102.1 HD signal, they are also heard in 'Press-kit' on not one, but two other signals: K228DF 93.5 and K269EE 101.7. Looking at the coverage maps for both, 101.7 seems more superior compared to the directional signal of 93.5, although both put a solid signal over Press-kit proper. There is no reason why KAH.M needs 3 signals covering the same area, unless... the BM format will be retained on the translators, with Chavez putting KNAI on 102.1. This brings me to my final point on why this will be happening, The KAHM calls will most likely be dropped for KNAI-FM. With no place to park them elsewhere, they can be grabbed up by another broadcaster, hence the new name with no call letters attached.
There's also KYCA-AM in Prescott that could be used to rebroadcast on either or both FM translators you mentioned.
