Final Thoughts for Operators

Having these frequencies programmed into your radio prior to heading off-grid ensures you always have a route for assistance or casual conversation. Make sure your handheld or mobile rig is set up for wideband operation on GMRS and that your offsets are correctly configured before keying up.

If you’re weighing whether a club is worth your time, see How to Find (and Vet) a Ham Radio Club Worth Joining and What’s Wrong With Amateur Radio Clubs in 2026. If none of these fit, Starting Your Own Ham Radio Club From Scratch covers what it actually takes. For the emergency and GMRS side, our GMRS Radio: The Complete Guide and Building a PACE Communications Plan for Grid-Down Scenarios pair well with the AZGMRS and AESG nets above.

Don’t See Your Area? Check ARCA

This guide focuses on the clubs and repeater systems I use and hear about most, but Arizona has far more than what’s listed here. The Amateur Radio Council of Arizona (ARCA) maintains a directory of over 50 affiliated clubs across the state going back to 1967, covering areas this guide doesn’t touch directly.

Download the CHIRP Repeater File

All of the repeaters listed above are pre-loaded into a CHIRP-compatible CSV so you can import them straight into your radio instead of typing them in by hand.

Import it in CHIRP under File → Import and select the CSV, then review each entry against your radio’s band plan before uploading to the radio. If you would rather skip CHIRP entirely for your ham gear, Nexus also does a full CHIRP CSV round-trip for around a thousand radio models straight from its own repeater search screen.
