...will give you a complete listing of the repeaters within 30 miles of the top of Mingus Mt.
Locally I use the 147.000, 147.220, 146.880, repeaters and for the surrounding area I use the ARA Rim Link (Mt. Elden in Flagstaff covers the Verde Valley and Prescott, Mt. Ord between Phx and Payson, Pinal Peak covers the eastern desert, and Green Peak near Springerville covers I-40 and parts of the White Mts.)

...Lists the Rim Link freq as well as the other ARA repeaters. The CalZona Link operates between Smith Peak near Aguila, AZ., and covers from the Cali border to Phx, and Monument Peak east of San Diego covers the western desert of Cali. I've used the CalZona link with very good success on I-10 from almost Yuma to the top of Yarnell Hill on Hyw 89 to Prescott.
Bill Williams Mt. has a very good repeater as well. 146.780, PL of 91.5 - it covers Prescott, Flagstaff, west on I-40 to well past Seligman, and north to the Grand Canyon.
