BeachNet Remote Receiver Systems
Because of the mountainous terrain in our area, it is not uncommon for a user's signal
to have multipath distortion at the repeater receiver. If the distortion is severe enough,
the CTCSS (PL) tone can be mutilated and the transmission will 'chop', making
it unreadable, even with a relatively strong signal. The hilly terrain
also causes user's signals to become weak when they enter shadowed 'dead spots'. Even
when the user can hear the repeater relatively well, they find themselves unable
to continue a conversation. The answer to this problem is a remote receiver that
hears the user better than the repeater site receiver.
BeachNet incorporates
two Remote Receiver systems. The simpler consists of a single remote receiver,
supporting the North Cove, 145.310,
repeater coverage along Highway 101, from Naselle to Bay Center. This is detailed at
the bottom of this page. The more elaborate system
consists of three remote receivers to
support the Megler 147.180 repeater.
Megler, 147.180 Repeater, Voting Receiver System
To solve
these problems we have installed several
Remote Receivers for
the Megler 147.180 repeater. These all listen on the same channel frequency as the
repeater receiver. To improve the user experience, an automatic Receiver Voting system
manages these resources in real-time.
The Voting System uses a Voting Unit at the repeater site
to constantly evaluate the signals fed in from the receivers, and determine which of the four
has the best signal at the moment.
The user does nothing special to select the best receiver. The Voting System will
do that automatically.
The Remote Receivers have overlapping coverage, virtually eliminating dead spots
in the Megler Repeater's coverage.
Even in places where the repeater transmitter sounds weak, with multipath and rough copy,
the signal
from the user is clean and clear. All four receivers (Cape Disappointment, Naselle, Warrenton and
the main Repeater on Megler Mountain), are constantly evaluated and the best signal of
the lot is routed to the
transmitter. If you can hear the 147.180 Megler repeater, you can probably work it,
with a typical 50-watt mobile and a 5/8-wave vertical antenna.
The Megler Receiver Voting System is now on line.
The remote receivers were installed and brought on-line between September and November 2008. The
system is now fully functional.

To use the Remote Receivers, set your radio to 147.180 +600 kHz,
and your PL tone to 82.5 Hz. The Voting Unit will
select the best signal from:
The Naselle Receiver (2000 ft),
Covers Hwy 101 from Hwy 4 Junction, north to Bay Center, east to Grays River, and the northern portion of the Peninsula.
The Cape D Receiver (300 ft),
Covers Cape Disappointment State Park and environs.
The Megler Repeater Receiver (1300 ft),
Covers the Peninsula from Chinook north to Oysterville,
and Astoria south to Seaside and east to Knappa.
The Warrenton Receiver (30 ft),
Covers Hwy 101 along the Columbia from Chinook, south to Astoria.

North Cove, 145.310 Repeater, Remote Receiver
Another 'rough' area for our repeater coverage is along Highway 101 from the
Hwy 4 Junction near Naselle, north to Bay Center. The North Cove repeater serves
this area fairly well, but with a site elevation of only 400 feet, the received
signal can be marginal much of the way.
To solve this coverage problem, a Remote Receiver
is located at 2000-feet on Naselle Ridge to pick up the
user's signal from a much better site. To utilize this Naselle Remote Receiver
to improve your signal, all that is necessary is to change your PL (CTCSS) tone to
114.8 Hz.

North Cove Receiver
Naselle Receiver
|
To use the North Cove Repeater with or without the Remote Receiver, set your radio to 145.310, -600 kHz,
and your PL tone to:
118.8 Hz. to select the North Cove Receiver (400 ft. Elevation),
located on the ocean bluffs above Tokeland.
114.8 Hz. to select the Naselle Receiver (2000 ft. Elevation
),
located on Naselle Ridge above Naselle.
The North Cove Repeater covers an area including
Highway 101 from the Hwy 4 Junction ('Johnson's Landing'), north to South Bend, and
then west to Tokeland and Grayland. Within this area, the Naselle Receiver helps greatly in
several portions, including Hwy 101 and along the north shore of Willapa Bay, from Raymond nearly to Tokeland.
