North Cove VHF Repeater

North Cove UHF Repeater

The North Cove repeaters
were returned to service
07/21/15 with an upgraded
antenna (Diamond X510 -
8db VHF & 11dB UHF) and
feedline (7/8-inch hard-
line). On 08/09/15 the
UHF repeater was replaced
with a more capable unit.

Location: The North Cove site is on the ocean bluff, overlooking North Cove, near Tokeland/Grayland, WA, above "Washaway Beach" on the north side of the mouth of Willapa Bay. The tower is visible on the headlands driving south-east bound on Highway 105, after making the turn to the east, about 3 or 4 miles west of the Tokeland turnoff.

Coverage: The two North Cove repeaters can be easily accessed north to Westport, WA, and south along the ocean side of the Long Beach Peninsula, especially the beach area. The coverage to the east overlaps with that from the South Bend, Naselle and Megler repeaters. The North Cove repeaters can be useful along Highway 101, especially the VHF repeater, which has a Remote Receiver at the Naselle site providing very good coverage from Bay Center, south along Highway 101 to the Highway 4 junction at "Johnson's Landing". To use this high-level receiver, shift your CTCSS (PL) tone from the usual 118.8 Hz to 114.8 Hz and your transmissions will be picked up loud and clear in this area.

The North Cove VHF machine was the first
BeachNet repeater. The original unit had been in service as the W7RDR repeater in Ilwaco, purchased new before 1980. That club had switched to a Motorola rig, in the mid-1990's. The machine became available and I adopted it, putting it on the air in 1998 from North Cove, on the Western Washington Shared Non-Protected (SNP) test pair of 145.290. At the time, it was linked to the 146.660 W7FBM repeater in Astoria. Later the frequency was changed to its permanent pair, 145.310. Still later, in the 1998-99 timeframe, the KO Peak UHF repeater/remote base went on the air, and this North Cove repeater was linked to that. In 2010, after more than a decade of continuous faithful service (two decades, if you count the W7RDR chapter) in support of Amateur radio, that particular unit was replaced with a newer duplicate model, and the original completely refurbished for return to the Pacific County ARC. That machine is now, once again, the 146.860 Ilwaco W7RDR repeater.

The 2-meter repeater is normally linked to
BeachNet, and like all of our repeaters, the link can be dropped to make this repeater stand-alone when that is desirable. The UHF machine normally operates stand-alone, providing a local-use alternative with better range than simplex to "talk around the corner", without using the entire network. The 444.400 repeater can be linked to the rest of the network when desired. It is normally considered to be reserved for the use of local Hams in the Tokeland/North Cove area for public service and emergency operations in support of that community.

Hardware: The VHF repeater consists of a GE Mastr-II station with PLL Exciter and a custom built interface plug-in card to support the GE Rangr transceiver used with a multi-element UHF Yagi for the system link. The VHF duplexer is a 4-cavity Sinclair Hybrid-Ring unit, originally used at the 146.760 Nicolai repeater in Oregon. Mice had chewed the cable harness, destroying the device, and the Sunset Empire club sold this unit to me as surplus. With a careful replacement of the harness, this unit once again performs well. The duplexer is mounted to the ceiling well away from the equipment rack to conserve space in this small building. The VHF repeater incorporates a CAT-200B controller and runs 40-watts to the Diamond X510HDN dual-band antenna (8.3dB VHF/11.7dB UHF) inside a Stationmaster radome shell, at the 100-foot level on the tower, fed with LDF5-50 7/8-inch hardline, through a VHF/UHF diplexer.

The UHF station previously used a duplex converted GE Mastr-II mobile. There once were several of these in the
BeachNet system, but they have all been replaced with station chassis units, which have superior performance in a number of ways. The UHF repeater runs 40-watts to a Motorola four-can bandpass type duplexer, sharing the feedline and dual-band antenna with the VHF station through a diplexer. The UHF repeater uses an Arcom RC-210 controller, which also manages the GE-Rangr link radio, which uses a multi-element UHF Yagi low on the tower. The basic controls for this link transceiver are mounted on a custom control card in the Mastr-II's card cage. Other than the shared antenna and feedline, the two repeaters operate independently with separate power supplies, controllers and link systems.
