The Utah VHF Society
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
Configuration: Normally, this
system is always 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
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
up-to-date map of the Intermountain Intertie.

The repeaters directly
linked into this system:
The Hidden Peak Repeater (at the top of the
Snowbird tram, at 11,000 feet) has several links. The
'hub' portion 'talks' directly to the following repeaters:
- 147.180 + Tone: 100.0
Hz. Hidden Peak
(East of Salt Lake City, Utah, at the top of the Snowbird
Tram) - Coverage into Park City, Heber, Duchesne, Coalville,
parts of northeastern Utah, southern slopes of the Uinta
mountains, and parts of southwest Wyoming. Note:
This repeater has spotty coverage in populated areas of the
Salt Lake and Utah valleys. This repeater is aligned
with the Utah VHF Society and is the northern Utah hub of the
Intertie. If you are interested in seeing
pictures of this this repeater and reading more about it, go
to the Hidden Peak Repeater
- 147.120 + Tone: 100.0
Peak (southwest of Salt Lake City, Utah) -
Coverage into the greater Wasatch Front area (i.e. Salt Lake,
Provo, Ogden) as well as to the west along Interstate 80 into
- 147.020 + Tone: 100.0
Lake (Laketown) - Covers Bear Lake and its
communities, and various portions of northeastern Utah,
southeastern Idaho, and southwest Wyoming.
note: The following repeaters share
the same frequency as two other Intertie repeaters, so
please refrain from using any of these three 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.
- 146.670 - Tone: 100.0
Hz. Aspen Mtn (south of Rock Springs, Wyoming) -
Covers the Green River/Rock Springs area and I-80 as far west
as Little America and is linked to the system via the Medicine
- 145.270 - Tone:
100.0 Hz. Scott's
Hill (approx. 2 miles south of Brighton,
Utah.) Coverage is nearly identical to that of the Hidden
Peak repeater, except that it has somewhat better
coverage in Park City, Deer Valley, and in the
Evanston/Kemmerer, Wyoming areas.\
- 145.270 - Tone:
103.5 Hz Levan
Peak (central Utah, near Levan.) The primary coverage area of
this repeater is along the Interstate 15 corridor
from Santaquin to south of Fillmore. It covers
large portions Juab and Sanpete counties plus
portions of Utah, Tooele, and Millard counties.
The link to the south:
- Tone: 100.0 Hz - Monroe Peak
(central Utah, near Richfield, Monroe). This
covers the I-70 and US-89 corridors around Richfield
from Santaquin in the north to the south to the
Panguich area along US-89 and Parawan on I-15 and to
the east into the Capitol Reef National Park area.
Until fairly recently, the link connecting
Northern and Southwestern Utah was done on the 222 MHz band,
linking Frisco Peak and Hidden Peak. While the equipment
is still present at both sites, the linking is now done on 70cm
between Frisco Peak and the 147.12 site on Farnsworth Peak.
Some of the repeaters linked on this path are
aligned with the Utah VHF Society, while some others are
voluntarily linked into the system by their respective
organizations and owners. Through the southern link, the
following repeaters are also connected:
- Southwest Utah:
- 146.940 - Tone: 100.0
Hz. Frisco Peak (Milford,
Utah) This repeater covers Delta, Cedar City,
and other parts of southwestern Utah and eastern
Nevada. This repeater is aligned with the Utah VHF
Society. Photographs of this and a few other sites
may be found here.
- 146.800 - Tone: 100.0
Hz. Blowhard Peak ( Near Cedar Breaks
National Monument) - Covers parts of southwestern Utah such
as Cedar City, Kanab, some of eastern and southeastern
Nevada, and portions of northwestern Arizona.
- 146.820 - Tone: 100.0
Hz. St George (Utah Hill, west of St
George) - Covers St. George, parts of southwestern Utah,
southeastern Nevada, and northwestern Arizona. This
repeater is aligned with the Utah VHF Society.
- Southeast/Central Utah:
- 146.960 - Tone: 100.0
Hz. Navajo Mountain (east of
Page, AZ) - Covers most of Lake Powell and large
areas of southern Utah as well as Northern Arizona. By local option, this repeater
may not always be linked to the Intertie.
- 448.600 - Tone: 100.0
Hz. Navajo Mountain (east of
Page, AZ) - Covers most of Lake Powell and large
areas of southern Utah as well as Northern Arizona.
This is an alternate access to the Intertie and may be
linked to it (and into Arizona) even if the co-sited
146.960 repeater is not.
- 146.880 - Tone: 100.0
Hz. Las Vegas (Mt. Potosi, SW of Las
Vegas) - Covers Las Vegas, southeastern Nevada. Note that this repeater may not
be linked to the Intertie at all times as this
capability is under control of the local operators.
+ Tone: 100.0
Lake (south of Fredonia, AZ) - Covers portions of
southern Utah and northwestern Arizona.
- 448.875 - Tone: 100.0
Hz Mt. Eldon (North of Flagstaff,
AZ) - Operated by the Arizona Repeater Association, this
repeater is usually linked to the intertie via the Navajo
Mountain repeater and it is through it that the one may
connect to more of the state of Arizona - See below.
- Other links into Arizona:
The Navajo Mountain site permits connectivity into Arizona via
Mt. Eldon through
the Rimlink System which covers about 50% of the state,
including the Phoenix area. The interconnection of these to
systems can be control by users on either side and users may
interconnect the systems using the control code of "##360"
and may drop the link using the control code of
"##370". The Arizona Repeater Association (ARA)
encourages users to talk to their friends in Arizona, or to
make some new Arizona friends. For more
information about the ARA, go to their web page: http://w7ara.org
The link to the north:
- Links into California:
There are UHF remote bases in California that control their
systems to bring up the 146.880 Mt Potosi repeater. These
California Remote bases are only controlled by them and 2
meter control back to California is not available to users of
the Intermountain Intertie or the Mt Potosi Repeater group.
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:

Since the installation of the War
Eagle repeater on 145.230, coverage into Boise is once
Links to the south:
As of late 2011, some of the links in
and out of Levan Peak are offline and it is not possible
to fully-connect it to the Intertie.
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: http://w7ara.org

Harrison (southern Idaho) For pictures
and other info. about this repeater, go here. Note that
this repeater shares the same frequency as the Scott's
Hill and Levan Peak repeaters - also linked via the
intertie: Please be aware of this when in an area
where overlap between these systems is possible!
- 145.230 - Tone: 100.0
Peak (near West Yellowstone) Go here for some
pictures and more info about this repeater.
- 145.230 - Tone: 100.0
Eagle Mountain (near Silver City) This
site provides coverage into the Boise area as well as much
of southwestern Idaho. Yes, it uses the same
frequency and tone as the Sawtelle Peak repeater.
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.
- Montana - Please note that
links to the Intermountain Intertie and Montana are through
Idaho (refer to map) so connectivity to Montana is
dependent on the status of portions of the Idaho link.
Also note that links into Montana have changed: For more
information, visit the Montana Repeater Link
Association web site. Please
direct any "Montana-related" questions to the email
address(es) at that site.
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.
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
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
Intermountain Intertie projects:
The following is an incomplete
list of projects that were completed recently and those that are
currently underway having to do with the maintenance and
enhancement of the Intermountain Intertie.
Peak: As of October 15, 2007, this repeater
- and its links - were completely operational but as of late
2011, one of the links has failed and Levan Peak cannot be
fully connected to the Intertie.
Peak: There are currently issues with
on-site desense on 2 meters. Due to the lack of winter
access, these cannot be addressed until summer.
- Medicine Butte
(about 10 miles northeast of Evanston, Wyoming):
In mid 2011, this site seemed to go off the air, but upon
investigation it was discovered that the small building to
which the antenna mast was connected had blown over in the
wind. Upon righting the building and loading it with
ballast (large rocks) the site returned to normal operation.
- Blowhard and Frisco Peaks: In
mid 2011, the UHF link radios at these sites were replaced,
allowing better frequency re-use, improving link margins and
solving some ongoing interference problems.
If YOU are interested in
helping out with any of these projects, please contact John Lloyd, K7JL.

Canyons Amateur Radio Club page describing this
system: This site also contains pictures of some of these
radio sites. Also, see the Other
