Welcome to the Arizona common/shared frequencies.


Arizona Interagency Radio System (AIRS)

AIRS is a suite of full-time, cross-banded (i.e. VHF, UHF, and 800MHz*) mutual-aid channels designated specifically for multi-agency use across the State of Arizona. Agencies wishing to operate on AIRS must sign a Memorandum of Understanding (MOU) with the Department of Public Safety (DPS) which holds the licenses for AIRS frequencies. AIRS is designed to provide interoperable communications capability to first responders of police, fire, and EMS agencies, as well as other personnel of municipal, county, state, tribal, federal agencies and approved non-governmental organizations (NGOs) performing public safety or public service activities.


These radio frequencies are to be used in the event of a multi-agency, multi-discipline, and/or multi-jurisdictional operation requiring the use of the common state radio channel(s), specifically for the use of coordinating activities during identified incidents. AIRS frequencies are not to be used by a single agency for routine public safety operations. AIRS frequencies may, however, be used by a single agency to reconstitute communications in the event of a system failure or other significant communications loss.

All participating agencies to the AIRS, program AIRS frequencies into their radios in order (AIRSAZ followed by AIRS1, AIRS2, AIRS3, AIRS4, and AIRS5). The programming zone may differ depending on the agency or the type of radio. Note that the AIRS applies specifically, and only, to AIRS-suite channels and does NOT include VTAC, UTAC, or 8TAC channels.

Statewide 800MHz Shared Channels

Interagency Law Enforcement National Calling Channels Interoperability Frequencies

The "V-Tac" and "U-Tac" frequencies are new nationwide VHF and UHF interoperability channels to join the existing 800MHz I-Tacs. They are narrowband only and interoperability is the primary use for these channels. They specifically are not to be used for communications internal to one agency but rather for multiple agencies, be they neighboring towns or from different parts of the country to talk to each other even if they don't have any other common channels. Agencies make contact on the calling frequency and then switch to a "Tac" channel to communicate. Many of the VHF and UHF channels are already licensed and in use by agencies in Massachusetts. Click on the Frequency to see the current licensees. Prior to Jan. 1, 2005, interoperability on these channels will be secondary to incumbents. After Jan. 1, 2005, the situation reverses, and the incumbents become secondary to interoperability use. Individual licenses are still required for fixed base-station operation on these channels. Mobile operation is permitted on these channels on a blanket basis, without an individual license similar to the 800 MHz interoperability channels.
