The Intermountain Intertie

The Intermountain Intertie is a more-or-less informal collection of repeaters located in northern Utah/Southwestern Wyoming, many of which (but not all) are supported in part by the VHF Society.  This system is a hub-and-spoke system, with the Hidden Peak (the so-called "Snowbird") repeater 147.18 (+) repeater acting as one of the hubs.  If you are interested in seeing pictures of this repeater and reading more about it, go to the Hidden Peak Repeater page.  There is also a page for the 146.86 Medicine Butte repeater.  To look at a growing collection of pictures and info about other repeaters in the Intermountain Intertie, go to the Other Repeaters of the Intermountain Intertie page.

Configuration:  This system is usually linked to other repeaters/systems in the network that collectively cover much of central and southern Idaho, southwestern Wyoming, northern Utah, western and southwestern Utah, northwestern Arizona, and northeastern Nevada.

Etiquette:  Because of this extensive geographical coverage, please be courteous of others that may be wanting to use the system, frequently leaving time for breaks, and limiting QSOs to no more than 10 minutes during the heavier usage times - and it is uncouth to monopolize the system at any time.  Keep in mind that it takes a good portion of a second for all of the various links to 'turn around' so be sure to pause for several seconds when you allow for breaks, and key up for about a second before you say your first word.

The repeaters directly linked into this system:

Please note:  The following repeaters share the same frequency as two other Intertie repeaters, so please refrain from using any of these repeaters in areas better-serviced by a more "local" intertie repeater.  Also be aware that the Mount Harrison repeater also shares 145.270 as well.
Currently off-air: The link to the south:

Some of the repeaters linked on this path are aligned with the Utah VHF Society, while others are voluntarily linked into the system by their respective organizations and owners.  Through the southern link, the following repeaters are usually connected:

There is an additional link that connects to the north into a similar system operated in Idaho.  The link to the north into Idaho connects these repeaters:
Current status of the Intermountain Intertie:

Promontory Point:

The "5.49" repeater (145.490 output, negative split) on Promontory Peak was added to the Intertied at the end of September, 2018.  Its tone was changed to 100.0 Hz to match the more common tone on this system.

Hidden Peak:

The Hidden Peak (a.k.a. Snowbird) repeater is currently online.

Links to the north:

Coverage into Boise is again possible with the installation of the 145.130 repeater (formerly on 145.270) on Shafer Butte (NW of Boise) along with a 2 meter repeater at the Mountain Home "relay" site on 145.150:  Both use 100.0 Hz tones.

Links to the south:

As of March, 2012 is is reported that the Jacob Lake repeater (147.30+) is linked to the intertie.  Please note that according to the wishes of the local operators, it may not always be connected to the Intertie.

As of September, 2013 there is capability to link the intertie into the Arizona Repeater Association (ARA) system.  For more information, visit their web site:

The link to the Monroe Peak repeater (central-south Utah) on 146.840 has failed as of December 2021 and the plan is to repair this link when possible, probably late spring 2022.

Connectivity into Montana has changed.  Please refer to the Montana Repeater Link Association web site for further information. 

IRLP Connectivity:  Direct connectivity to IRLP Node #3660 is currently NOT available.  Please read this for more information.

Note:  While many of the participating systems are usually linked into the Intermountain intertie, they may be occasionally disconnected due to local requirements.

For more information, send email to John, K7JL (at the link below) and he will forward your request to the appropriate party.

Occasionally, connectivity into Oregon (and other areas) is possible.  This can happen when operators of those other systems remotely link into an intertie-connected repeater. Note:  Such operations are not usually under direct control of the operator(s) of an intertie repeater.

There are other repeaters that may be linked to the above repeaters on a full or part-time basis.  Information on other repeaters will be posted if/when it becomes available.

"Who maintains all of this?"

A system this extensive cannot practically be maintained by just one person.  Suffice it to say, there are a few key people who do most of the work to keep this system operational.  To list those people here would be unfair, as it is a group effort and someone would undoubtedly be overlooked.

If you wish to help maintain this system, please join the Utah VHF Society (the address is given on the  home page) or the appropriate local repeater group (for those outside of Utah.) If you have any questions about this system, feel free to ask John Lloyd, K7JL.  Even if he isn't in charge of the repeater(s) that you are wondering about (i.e. the Southern Utah, Idaho or Montana repeaters), he can probably put you in touch with those who are

Current Intermountain Intertie projects:

The following is an incomplete list of projects that were completed  and those that are currently underway having to do with the maintenance and enhancement of the Intermountain Intertie.

If YOU are interested in helping out with any of these projects, please contact John Lloyd, K7JL.

Some additional information may be found at the  Rainbow Canyons Amateur Radio Club page describing this system:  This site also contains pictures of some of these radio sites.  Also, see the Other Repeaters of the Intermountain Intertie page.
