Grays River VHF Repeater

Location: The Grays River repeater is located just south of Highway 4 near the crest of KM Hill about half-way between Naselle, WA, and Cathlamet, WA, in Wahkiakum County. KM Hill is the highest point on Washington State Highway 4 between Longview, WA and the Coast, dividing the county roughly in half.

Coverage: Also called the "KM Hill" or just "KM" repeater, it provides coverage to nearly all of Wahkiakum County, from County Line Park at the east end, west along Hwy 4 into Naselle, at least to the junction with Hwy 401. The Eden Valley area, in western Wahkiakum County, is shadowed, but is well served by other
BeachNet, repeaters. On the Oregon side of the Columbia River, it fills in coverage along Highway 30 from west of Knappa to east of Westport, OR.

Normally linked to the rest of
BeachNet, this machine can be separated to operate stand-alone or linked to the 444.500 Nicolai repeater, as desired for ARES/RACES operations in Wahkiakum County. It provides a link to the State ECC at Camp Murray, through the network, and acts as a focus for Emergency Communications in this rural county. There is a generator at the site, for back-up power.

Hardware: The repeater consists of a GE Mastr-II 110-watt continuous-duty base station. The transmitter signal passes through one 8-inch BpBr cavity and a 5-inch bandpass cavity, and then feeds a Diamond dual-band antenna at the 65-foot level on the tower which serves the repeater transmitter and the UHF link transceiver through a diplexer, and 75-feet of LDF4-50, half-inch hardline. The repeater receive antenna is a high-gain Stationmaster at the top of the 90-foot tower, fed with LDF5-50 7/8-inch hardline, with a single 8-inch BpBr cavity. This two-antenna system allows optimal receiver performance with less than 1 dB combined loss. If you can hear this repeater, you can probably work it.

Packet Radio: The "KMHILL" packet radio node is located on this site as well. This is part of the 145.630 MHz 1200-Baud Washington District Three EOC Packet Network. The purpose of this node is to provide a link between the western portion of the county and the county seat in the eastern part.
