South Bend UHF Repeater
|
Location: The South Bend repeaters are on
1300-foot high
Holy Cross Mountain
between South Bend and Raymond, WA., with the several towers on
the hill visible from nearly any place in either city.
There is an unobstructed line-of-sight path from
the Pacific County Courthouse, where the Emergency Operations Center
(EOC) is located. The Courthouse and EOC
are surrounded by high ground on the other 3 sides,
with only poor VHF/UHF paths to the rest of the county. While
Holy Cross Mountain blocks simplex signals to the north, it also
provides an excellent repeater platform. Follow these
links for information on the co-located
147.340 MHz and
224.820 MHz
repeaters.
Coverage:
The "Holy Cross"
repeaters
can be used on the
northern third of the
Long Beach Peninsula,
south on Highway
101 beyond Bay Center,
west to Tokeland, east
throughout the Willapa
Valley and on Hwy
6, all the way
to the eastern county line.
The coverage follows Hwy 101
north to
the Pacific/Grays Harbor County
line. These repeaters
do quite well, within their
intended coverage area.
The 442.675 "Holy Cross"
repeater normally operates in parallel with
the 147.340 MHz machine,
coupled together as a single, dual-band, resource, and
linked to
BeachNet.
In fact, with careful radio adjustments, it is possible to
operate full-duplex (talk and listen at the same time,
like a telephone) between two Amateurs equipped
with dual-band transceivers. If attempting this,
we remind you that you must still drop your transmitter at least
once every 3-minutes to avoid timing out the repeater, and to let
another Ham join in if they want to.
When desired, we can
un-link them, providing separate
repeaters for different jobs. The
network link can be tied to
either, or neither. This
flexible functionality
supports the Pacific County
Emergency Management Agency,
providing intra-county
and extra-county back-up
emergency communications.
Hardware: The
442.675 MHz
repeater is a
GE
Mastr-II
continuous duty base station. The UHF
repeater is a 110-watt unit running
about 40-watts.
The UHF cabinet (left-most picture below)
holds the UHF repeater
and duplexer.
The VHF cabinet holds (second from
left
picture below, top to bottom), the
control receiver, controller,
VHF repeater and power supply, with
the Mastr-II mobile-style
link radio on the side of the cabinet.
The two repeaters
share the single power supply,
controller and Hustler G6-270 antenna
at 80-feet up the 140-foot tower, fed
with LMR-600.
The Link-Comm controller
manages both repeaters, a
link transceiver, and a Mastr-II
auxiliary control receiver.
The UHF repeater uses a Wacom BpBr
four-cavity duplexer.
Packet Radio: The
"HOLYX" packet
radio node is located on this site
as well.
This is part of the 145.630
MHz 1200-Baud
Washington District Three
EOC Packet Network.
Also at the site is
the "HOLYMB"
public mailbox. There is no
forwarding or other service
with this mailbox, but it
is available for any Pacific
County Amateur to use,
provided that they will
check frequently for mail.
This allows those who
choose not to maintain
a full-time
packet presence to have
a 24/7 mail drop available.
The HOLYX packet
station is owned by Pacific
County Emergency Management
Agency, and is considered
part of the South Bend
EOC RACES Amateur radio station.
