Megler VHF Repeater
Note the 82.5 Hz CTCSS (PL)
Tone on the 147.180 repeater
Location: The Pacific
County Megler radio
site is located
of the town of
Chinook, WA, on
the north side of
the Columbia River, overlooking Astoria,
OR to the south and Long Beach, WA to the west,
from an altitude of about 1300 feet. There are
several different sites,
miles that are collectively
known as "Megler", and
this is the nortwestern-most
and highest of these. The other
sites are prominently visible
above the Astoria-Megler
Access to these other
sites is via the logging
road across from the
Nitch" rest area
on Highway 401 just
east of the Astoria-Megler
bridge. The Pacific
County site is reached
by way of the Chinook
quarry road. Although
not visible from the
bridge, the Pacific
County site can be
spotted from Highway
101, southbound, just west
of Chinook, look up
and to the left, to
the north of the highway.
"Megler" repeaters cover
nearly the entire
Long Beach Peninsula, and north
along the coast including parts of
Tokeland, Grayland and
Westport, WA. They can be utilized
east nearly to Longview, WA, and
south to Seaside, OR. To the west, they have both
been worked from
60-miles or more at sea.

The VHF coverage is a bit better than
the UHF coverage, as one would
The building and tower
are crowded with a number
of commercial, public safety and
broadcast stations, including six,
one-kilowatt television transmitters
that serve the greater
Astoria-Long Beach area, giving the site a high noise floor,
making operations there challenging.
Even though they
are stacked one atop the
other in the rack,
the 147.180 and 444.925 repeaters have different missions and operate
The 2-meter repeater
is normally linked to the
system of repeaters. The UHF repeater is not linked to
and operates "stand-alone".

information on the Megler 444.925 IRLP repeater.
The 147.180 Megler Repeater
operates full-time as a part of the
system of linked repeaters. It can be disconnected to
operate as a stand-alone resource, or in other configurations
to address particular needs. The only "regular"
instance of this is two days at the end of August each year,
when the Megler 147.180 and 444.925 repeaters
are split off in support of the Hood-To-Coast
There are four additional remote receivers supporting
the "Megler" repeater.
These fill coverage in
areas from which it would otherwise be difficult to
access the repeater.
The audio from each of these
routed to a "receiver voter", which
evaluates each of the five
channels for signal-to-noise-ratio.
The best of the lot is
"voted" and sent to the transmitter.
Follow this link for more
information on the remote receivers that support the
Megler VHF repeater, and the
repeater consists of a
110-watt continuous duty base station
and matching power supply, running 75-watts out to
to a Hustler G6-144 VHF antenna on the roof of the building,
through a circulator, a bandpass cavity, two BpBr cavities
and 50-feet of half-inch hardline.
The main receiver shares
a G6-270 dual-band antenna
at the top
of the 80-foot tower with the
antenna is fed with 100-feet of
LDF5-50 7/8-inch hardline.
The receive signal passes
through two BpBr cavities and
the resultant audio is
routed to an LDG RVS-8 receiver voter.
Each of the four
receiver packages consists of
a VHF GE Rangr mobile radio (modified
to work in the Amateur 2-meter band), a UHF
GE Rangr mobile radio
(modified to work in the 430-MHz band),
a DTMF decoder, a Communications
Morse code identifier, and in two cases, a
high-gain ARR VHF preamp
and VHF/UHF diplexer. These two
and Cape D)
are in "cosmetically
sensitive" areas where a single antenna
is called for. They
use Hustler G6-270 dual-band antennas.
The third receiver package
(Naselle) shares the Comet x510 main repeater antenna
for VHF receive and uses a Cushcraft 6-element
yagi for the UHF link.
The fourth package (Seaside) uses a Hustler G6-144B
6 dBd gain vertical for VHF receive and a Diamond 10-element,
13 dBi yagi for the UHF link to Megler.
Each of the four
remote receiver channels is picked up
at the Megler repeater
site on a Hustler UHF vertical,
split four ways
with a home-brew constant-impedance
and routed to four
GE Rangr UHF mobile radios
(also modified to work at 430-MHz)
as link receivers.
The recovered audio signals are
routed to the LDG receiver voter
along with the main repeater receiver
and the best of the five is fed to the
transmitter through a GE Audio
link is supported
by a GE Rangr UHF transceiver
running 5-watts through
a DCI Filter and 60-feet
of LMR-400 coax to a 6-element,
The controller is a CAT-200B from
Computer Automated Technology.
