Minot UHF Repeater
Minot VHF Packet

Location: Minot Peak is south of Elma, WA, and
west of Centralia, WA.
Coverage: Minot covers most of southern Grays Harbor
County. It is accessible from the EOC in Montesano,
as well as most of Aberdeen, Hoquiam and the other major towns. This repeater provides
coverage on Highways 8 and 12 from Aberdeen on the west to McCleary on the north,
and most of the Centralia/Chehalis area.
The coverage to the north is more spotty than the site plot would indicate,
and local obstacles can influence the quality of coverage greatly, particularly
in wooded or hilly areas.
Part of the
BeachNet
system, this repeater solidifies coverage for those passing through
between the coastal areas and Puget Sound.
Minot provides back country coverage in mountainous southeastern
Grays Harbor and
northeastern Pacific Counties.
During an emergency, this repeater will probably be disconnected
from the network, and linked to the Cosmopolis (145.390) repeater to allow
communications within Grays Harbor County. This arrangement
allows both repeaters to be simultaneously monitored on a single
radio from the Grays Harbor EOC in Montesano.
Hardware: The repeater consists of a GE Mastr-II 110-watt continuous duty
base station (running 60-watts)
using a CAT-200B controller in a 30-inch GE cabinet with a
Mastr-II power supply. The duplexer is a Phelps-Dodge 6-cavity
bandpass-notch type feeding a
dual band antenna through 70 feet of LDF5-50
7/8-inch hardline. There is a UHF GE
Mastr-II mobile used as a link transceiver
and a VHF Mastr-II mobile used for the packet station.
Both are mounted to the sides of the cabinet. All
three transmitters are
fitted with dual-section isolators and bandpass filter cavities.
The packet station and
repeater share the main antenna on the tower
through a diplexer, while the
link uses a pair of phased yagis
on the roof of the building.
Packet Radio: The
"MINOT" packet radio node is co-located
with the UHF repeater and shares the antenna.
This is part of the 145.630 MHz
1200-Baud Washington District Three EOC Packet Network. The packet station is
accessible from most of southern Grays Harbor County as well as the northern portion
of Pacific County, and also provides coverage into the Centralia area.
