The 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.
All of the repeaters in this system are linked together. When you send a transmission to any repeater in the system, your transmission is relayed to all of the other repeaters in the system and each repeater broadcasts your transmission. Using this system 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, you should listen for a few moments before sending a transmission to ensure you don't double on another operator's transmission. It can take a full second for all the links between the repeaters to activate. For best results wait a second after you key up your radio before you begin speaking: this will ensure your entire transmission is relayed to all the repeaters in the system. During your QSO pause frequently for several seconds to allow another operator to break in and activate all the repeater links.
