South Bend 220 Repeater


Note the 82.5 Hz CTCSS (PL)
Tone on the 224.820 repeater

Location: The South Bend station is on Holy Cross Mountain between South Bend and Raymond, WA., with the several towers on the hill visible from nearly any place in either city. The site is line-of-sight from the Pacific County Courthouse, where the Emergency Operations Center is located. The Courthouse and EOC are surrounded by higher ground, 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 platform for a repeater. Follow these links for information on the co-located 147.340 MHz and 442.675 MHz repeaters.

Coverage: The "Holy Cross" 224.820 repeater can be used from most of Pacific County, including the bulk of the Long Beach Peninsula. This repeater can be used south from South Bend on Highway 101 beyond Bay Center, and has been worked from as far south as Astoria. Coverage extends west on Highway 105 to Tokeland, Grayland and Westport, east throughout the Willapa Valley and on Highway 6, all the way to the eastern county line, and follows Highway 101 north beyond the Pacific/Grays Harbor County line. Even at its relatively low power output, this repeater does quite well, within its intended coverage area.

The 224.820 repeater is normally linked into
BeachNet, however, it can be disconnected from the Network and operated stand-alone. This repeater also supports a 6-meter remote base capable of working several distant repeaters, as well as having great simplex range.

The 224.820 repeater is intended to be used as an "intercom" between the County EOC at South Bend and the AEOC at Long Beach. The 6-meter remote base can be shared by these stations to monitor or join one of the State emergency Nets on that band. This flexible functionality supports the Pacific County Emergency Management Agency, providing intra-county and extra-county back-up emergency communications.

Hardware: The 224.820 repeater consists of a GE Mastr-II High-Band VHF continuous duty base station converted to operate on the 1.25-meter band. The transmitter consists of a PLL-type exciter modified to operate at 224-MHz, instead of the original frequency of 150-MHz., and a home-brew power amplifier that puts out about 25-watts. The power amplifier is mounted to a heat sink originally intended for a 75-watt station, so overheating should not be a problem.

The receiver, also heavily modified, has a sensitivity of better than 0.2-microvolt for 12 dB SINAD. A GE Audio Card is used for audio processing, and a Communications Specialists TS-64-ds CTCSS decoder is mounted on the Audio Card to handle receiver access. The duplexer is a Sinclair BpBr type, the controller is an Arcom RC-210, built from a kit, and housed inside the repeater station. The 6-meter FM remote base consists of a GE Rangr radio running 80-watts to a Cushcraft Ringo antenna above the repeater building roof. There is a second GE Rangr, on UHF, used for a network link. The repeater shares a multi-band antenna with the 2-meter packet station.

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, which it supports.
