North Cove VHF Repeater
North Cove UHF Repeater
The North Cove repeaters
were both refurbished and
returned to service, August
of 2015 with upgraded
antenna, feedline, chassis,
RF decks and linking radios.
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 along State Route 105 to
Westport, WA, and south along the ocean side of the Long
Beach Peninsula, especially the beach area.
Looking due south from
the repeater site, the tip of the Long Beach Peninsula
is only six miles away, with the repeaters looking down the
beach. The Surfside community is only 12 to 14 miles away.
to the east overlaps with that from the South Bend, Naselle and Megler
repeaters. The North Cove repeaters can be particularly useful along
Highway 101 while driving the eastern shore of Willapa Bay,
especially the VHF repeater. The over-water path to
most of Highway 101, from South Bend (milepost 53) to
the Bear River area (milepost 20) provides nearly spotless coverage.
The one place that might be problematic is between Milepost 29 and
milepost 32, where the highway dives into the woods. To cover this
problematic area, we have installed a
remote receiver at the Naselle site
providing very good coverage in this area, and usable 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.
History: The North Cove VHF machine was the first
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 GE machine became available and I adopted it,
putting it on the air in 1998 from county's brand new
North Cove radio site. In fact the site was so new,
my repeater was one of the first pieces of equipment
installed there. To start with, this repeater
operated on the
Western Washington Shared Non-Protected (SNP) frequency pair of 145.290.
The SNP pairs are considered test pairs, open to anyone on a
not-to-interfere basis. 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,
I replaced that
particular unit with a newer duplicate model, and the original
completely refurbished and returned to the Pacific County ARC. That machine
is now, once again, the W7RDR 146.860 Ilwaco 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.

The CAT-200B controller is housed inside the
repeater chassis, on the control
shelf. A custom-built plug-in card interface
supports the GE Rangr transceiver,
mounted to the top of the repeater chassis,
used in conjunction
with a tower-mounted multi-element UHF
Yagi for system linking.

space in this small building.
The VHF repeater runs 40-watts
and shares the Diamond X510HDN dual-band
antenna (8.3dB VHF/11.7dB UHF) with
the UHF repeater using a diplexer.
The Amateur antenna is
sheltered from the weather
inside a Stationmaster radome shell
(from a retired commercial antenna),
at the 100-foot level on the tower,
fed with 120-feet of
LDF5-50 7/8-inch hardline.
The UHF station previously
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 Arcom RC-210 controller,
mounted inside the repeater chassis, manages the
UHF repeater and
GE-Rangr link radio, which uses a multi-element
UHF Yagi mounted low on the tower. The basic controls for this link
transceiver are mounted on a custom control card in the Mastr-II
station's card cage.
Other than the shared antenna and feedline,
the two repeaters operate independently with separate
power supplies, controllers and link systems.
