KAHM has an effective radiated power (ERP) of 58,000 watts, broadcasting from a tower at 770 meters (2,530 ft) in height above average terrain (HAAT).

It provides the Prescott, Flagstaff and Phoenix areas with a format of Beautiful Music, which remains virtually unchanged.

The station originally aired quarter hour sweeps of easy listening music, mostly instrumental cover versions of popular adult songs, with some Broadway and Hollywood show tunes.

With the improved signal, KAHM could be heard in southern Arizona as far south as Peoria, Scottsdale and Anthem.

Effective January 12, 2018, Southwest Broadcasting sold KAHM (as well as translator K269EE and sister talk KYCA and its translator K278CN) to Phoenix Radio Broadcasting, a holding company for the Cesar Chavez Foundation's Farmworker Educational Radio Network.
