Olympia UHF Repeater



Olympia Packet Station


Note: in November 2012, we
experienced an antenna failure.
On June 3, 2013, the damage was
repaired and the station is now
back in normal operation. Packet
station #2 was also switched to
145.01 from 145.05 MHz.

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 Coordination Center at Camp Murray. This repeater is directly accessible from the Grays Harbor EOC in Montesano.

Hardware: The repeater itself 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. A pair of 40-watt VHF Mastr-II mobiles support a dual-frequency packet station. The two packet radios use a four-cavity combiner and a VHF/UHF diplexer to share the main station antenna with the UHF repeater. There is a UHF GE Rangr mobile, used as a link transceiver, feeding a 10.2 dBi, 6-element Cushcraft Yagi through 100-feet of LDF4-50, half-inch hardline, 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 NOTAC, while on the 145.630 side you might use MINOT. The packet station is owned by N7UJK.
