Olympia UHF Repeater
Olympia Packet Station
|
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 of
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.
Affiliated with the
BeachNet
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. In normal times,
it serves those
traveling between the coastal
counties and Puget Sound, providing solid mobile
communications nearly the
whole way
between the Seattle-Tacoma area and
eastern Grays Harbor. For those traveling
south on Interstate-5 from the Sound, this repeater has solid coverage
to a point just north of Longview.
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 Command Center at
Camp Murray. This repeater is directly
accessible 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)
with a CAT-200B controller. The duplexer
is a Phelps-Dodge bandpass-notch 6-cavity
type feeding a Comet x510 high-gain
dual band antenna (in a commercial
radome shell)
through 120 feet of LDF5-50 Andrew
7/8-inch hardline. There is a 40-watt
UHF GE Mastr-II
mobile (running 10-watts) used as a
link transceiver,
and a pair of 40-watt VHF Mastr-II mobiles
supporting a dual-frequency packet station. The
two packet radios use a four-cavity combiner
and a VHF/UHF diplexer to share the main
vertical antenna with the UHF repeater, while
the link uses 100-feet of LDF4-50
half-inch hardline and a 13 dB yagi.
All four transmitters are fitted with
dual-section isolators and bandpass filter cavities.
The entire station, including the Astron 60-Amp
power supply, six 2-meter cavities,
packet controller, weather station
and a master control panel with separate speakers
and audio test taps for the receivers, fits in a single
6-foot rack cabinet.
Packet Radio: The
"N7UJK-8, -9, -10" packet
radio digipeater/bridge
is located at
this site. This is part of the 145.630 MHz
1200-Baud Washington District Three
EOC Packet Network,
allowing traffic to pass to and from the Puget
Sound 145.01 MHz net.
This is not a node but a digipeater.
Do not connect to it, but
through it, using the "via"
command. To digipeat on the 145.630
frequency, use "via N7UJK-8".
To digipeat on the 145.010
frequency, use "via N7UJK-9".
To digipeat
through the bridge, in either direction
between these two frequencies,
use "via N7UJK-10". A suitable
"target node" on the 145.010 side
is SEA, while on the 145.630 side
you might use MINOT. The
packet station
is owned by
N7UJK.
