System Architecture
How Arizona Linked Repeater Networks Work
Mountain-to-Mountain RF Linking
Linked systems utilize dedicated UHF/microwave point-to-point auxiliary links between high-elevation mountaintops (such as Mount Ord, Mingus Mountain, and Mount Elden). These backbones operate independently of the public internet to ensure emergency survivability.
Telephone Autopatch
Systems like ARA MetroLink feature integrated telephone autopatch controllers covering major Arizona area codes (480, 602, 623, 928, 520), enabling members to place emergency or routine outbound telephone calls from handheld or mobile radios.
Unified Audio Distribution
Simultaneous full-duplex repeating means an operator in Tucson or Globe on EAARS or Phoenix on MetroLink can hold conversations with someone on a 5-watt handheld in Flagstaff or the White Mountains in real time.
