Olympia UHF Repeater
Olympia Packet Station
Note: as of 01/15/18, we
experienced a receiver
failure. The repeater is
off the air until repairs
can be completed. Sorry
for the inconvenience.
Location: Capitol Peak, in the Capitol State Forest,
southwest of Olympia. To avoid
confusion with the 145.470 repeater, which has been known for a long
time as "the Capitol Peak Repeater", we refer to our
machine as the "Olympia" repeater.
You may also hear ours referred to as "CPU", which stands for
'Capitol Peak UHF'. The associated packet station is sometimes called
"CPP" for 'Capitol Peak Packet'.
Coverage: The Olympia repeater has very good coverage in
eastern Grays Harbor County, being quite usable as far west as Aberdeen.
The real strength of this repeater is bridging the gap into Puget Sound.
Coverage extends well north of Tacoma, in fact the station has been worked from
downtown Seattle, as well as the Hood Canal area. The State ECC at Camp
Murray, near Fort Lewis, has solid access for emergency communications.
It serves those
traveling between the coastal
counties and Puget Sound,
providing solid mobile
communications nearly the
whole way. For those traveling
south on Interstate-5 from the Sound,
this repeater has solid coverage
to a point just north of Longview,
444.500 repeater coverage
Interstate-5 near Olympia, and Hwy-101
from Olympia to Shelton on the north,
and McCleary on the south are shadowed
somewhat due to the mass of Capitol Peak
itself, blocking signals to the site.
Affiliated with the
system, this repeater is owned by N7UJK, the EC/RO for ARES/RACES
in Grays Harbor County. It's primary purpose is to support
Auxiliary Emergency Communications
in and around Grays Harbor County, and the
rest of District Three in times of need.
During an emergency, this repeater will probably be disconnected
from the network, to allow
communications within Grays Harbor County, ARES District Three,
and to provide a link to
the State Emergency Coordination Center at
Camp Murray. This repeater is directly
accessible from the Grays Harbor EOC in Montesano.

A pair of 40-watt VHF Mastr-II mobiles
