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

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
connected together covering parts of five states.
