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
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,
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
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.
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
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
Other than the shared antenna and feedline,
the two repeaters operate independently with separate
power supplies, controllers and link systems.
