Naselle UHF Repeater

Location: The Naselle repeater is located on Naselle Ridge, also called Radar Ridge, overlooking the town of Naselle, WA. The logging road is good enough for a regular car (4-wheel drive not necessary) most of the year, although snow can close access in the winter months.

Coverage: Naselle provides good access for
BeachNet users in southern Pacific County, with the generous range you would expect from a 2000-foot elevation. It covers areas of the county that would otherwise be isolated from the network, including Naselle itself. It also provides valuable coverage to the east, in the Deep River area and western Wahkiakum County. To the north, the Naselle repeater covers the Nemah area, including Highway 101 from the Naselle River to Bay Center, and the timberlands east of the highway. The station can be worked from most parts of the northern portion of the Long Beach Peninsula, and the Tokeland area. Coverage extends south into Clatsop and Columbia Counties, in Oregon.

Hardware: The repeater consists of a GE Mastr-II 110-watt continuous duty base station (running 60-watts) with a dual-section isolator and DCI bandpass filter. The duplexer is a 4-cavity Sinclair BpBr type feeding a Comet X-510 dual band antenna (inside a Stationmaster shell) at the top of the tower, through 100 feet of LDF5-50 7/8-inch hardline. The main antenna is shared with two remote receivers, one supporting the North Cove 145.310 repeater and the other part of the Megler VHF voting receiver system to enhance VHF coverage into otherwise shadowed areas. While the siting and coordination of 2-meter repeaters has become quite difficult as the band has filled up, there are few such restrictions on remote receivers. The repeater incorporates an ACC RC-96 controller and a Mastr-II power supply. There is a dedicated GE Mastr-II control receiver for the repeater.

The remote base uses an ACC FC-900 interface and incorporates Icom transceivers for the 140, 220 and 440-MHz bands, sharing a CX-333 tri-band antenna (half-way up the tower) fed with half-inch hardline. In addition to providing the day-to-day linking of this repeater to the network, the remote base is capable of linking to many repeaters in the Longview and Portland areas, as well as up and down the coast, making it a cornerstone of the ARES/RACES Emergency Response Plan for Pacific County.

Construction Note: While most Amateur repeaters can take years to become a reality, this was a case where having a well-stocked spare parts locker accelerated the process considerably. An offhand comment by an acquaintance led me to believe a rent-free billet might be possible. This required soliciting permission from the site owner, including attending a meeting of their governing board to formally ask permission. Obtaining the cooperation of Pacific County Emergency Management Agency and it's oversight Council required attending another meeting. It meant assembling, fabricating and testing the station components in my shop, followed by installing the equipment at the site. On the paperwork front, there was finding a likely frequency pair, negotiating with the co-channel neighbors by email for letters giving conditional permission to share their pair for testing, and filing with WWARA toward repeater coordination and permission to build and test. All this was accomplished (from twinkle-in-the-eye to finished working repeater) within three weeks, the time it took for the four custom-fabricated crystals to arrive. This repeater filled the last remaining "hole" in the Pacific County coverage. On the air 28 July 2005.
