Radio station KAJM, known as 'Mega 104.3', has expanded its reach in Phoenix by adding a simulcast on the 99.3 FM frequency. The 99.3 translator, owned by Sierra H co-owner Ken Brentlinger, was previously linked to the now-silent 1580 KQFN in Tempe. This strategic move allows KAJM to cover not only Camp Verde, AZ, but also Phoenix and its neighboring cities of Glendale and Scottsdale.

Why it matters

The expansion of KAJM's reach through the 99.3 FM simulcast allows the Rhythmic AC station to tap into a larger audience in the Phoenix metropolitan area. This could lead to increased listenership, advertising revenue, and overall growth for the station.

The details

The 99.3 translator broadcasts from Phoenix's North Mountain with 250 watts of power, ensuring coverage of the entire city and beyond. The source of its programming is Audacy's 107.9 KMLE-HD3 in Chandler. KAJM's main signal, a powerful 40kW/807m, already rimshots the Phoenix market from the northwest. The station's recent success is evident in the Holiday 2025 Nielsen Audio ratings, where it achieved a 1.6 share.

  • KAJM's 99.3 FM simulcast launched in April 2026.
