Repeater Site Information and Photos

Following is information about each of the repeaters that are affiliated with the Intermountain Intertie System.  The original link was between Frisco Peak and Utah Hill and used Motorola L-44 tube radios.  This link worked reasonably well and a short time later a link to the Snowbird repeater was established.  Terrain limitaions would not allow us to use 440 MHz frequencies and the first link to Snowbird was established using Clegg 220 MHz amateur equipment.  The system often failed and was later replaced with 420-440 MHz radios going to Farnsworth Peak which had a better path profile.

Most, but not all, of the repeaters listed here are part of the Intermountain Intertie.
Sites for the most part are listed geographically, North to South.   Most links are generally left on, which means the entire system is connected unless there is a need to disconnect a portion for some reason.  At the present time there can be as many as 28 repeaters connected together covering parts of five states.
