Intermountain Intertie

The Intermountain Intertie is a system of linked repeaters located in Utah, Idaho, Wyoming, Arizona, and Nevada. The Utah VHF Society operates many of the repeaters. The Arizona Repeater Association operates the repeaters in Arizona, except for the one at Jacob Lake. The rest of the repeaters are operated by individual hams or other clubs. The Utah VHF Society coordinates the links between all the repeaters in the system.

The Intertie does not use the internet to relay signals between repeaters. Link radios and antennas operating on amateur radio frequencies carry all traffic. When you key up any repeater in the system, your signal is relayed over these links to all of the other repeaters. Using the Intertie, a ham radio operator in Idaho can easily communicate with another operator in Arizona using a handheld radio with 5W of power.

Because of the broad geographic reach of the Intertie, listen for a few moments before you call to make sure you don't double with another operator. It can take several seconds for all the radio links to activate. For best results count several Mississippis after you push to talk before you begin speaking: this will ensure the first part of your transmission is heard on all the repeaters in the system. While you're talking, pause frequently for several seconds to give another operator the opportunity to break in across the network.

The following repeater systems are not connected to the Intertie full time, but can be temporarily connected by their administrators or operators:
