Grays River VHF Repeater

Network link is temporarily down. The KO Peak station went off the air during a thunderstorm recently, taking the primary network links with it. Until a site visit can be arranged to assess and repair the damage, the network link from the Grays River 147.020 repeater is inoperative.

Location: The Grays River repeater is located near the crest of KM Hill about half-way between Naselle, WA, and Cathlamet, WA, on Highway 4 in Wahkiakum County. KM Hill is the highest point on 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, and west along Hwy 4 into Naselle. On the Oregon side of the Columbia River, it fills in coverage along Highway 30 between Bradley Summit and Clatskanie, 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 no generator power at the site, so the back-up is provided in the form of two deep-cycle 90-AH batteries. The repeater announces when it is operating on emergency power to advise users, and automatically reduces the repeater output power by about 6dB to conserve the batteries. If desired, a control operator can remotely switch between high and low power as the situation warrants.

Hardware: The repeater consists of a GE Mastr-II 110-watt continuous-duty base station. The transmitter feeds a Diamond dual-band antenna at the 65-foot level on the tower which serves the transmitter and the UHF link. This antenna is fed with LDF4-50, half-inch hardline. The receive antenna is a high-gain Stationmaster at the top of the 90-foot tower, fed with LDF5-50 7/8-inch hardline. The two-antenna system allows optimal receiver performance. If you can hear this repeater, you can probably work it.
