South Bend 220 Repeater

Tone on the 224.820 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 442.675 MHz repeaters.

Coverage: The "Holy Cross" 224.820 repeater can be used from most of Pacific County, including the northern two-thirds of the Long Beach Peninsula. This repeater can be used south from South Bend on Highway 101 to well beyond Bay Center. There is spotty access as far south as Astoria, OR. Coverage extends west along Highway 105 to Tokeland, Grayland and Westport, and out to sea. The repeater is easily accessible to the east throughout the Willapa Valley and along Highway 6, almost to the eastern county line. Coverage follows Highway 101 north to the Pacific/Grays Harbor County line. Access is spotty to the north from there, restricted mostly to high ground. Even at its relatively low power output, this repeater does quite well, within its intended coverage area.

Linking: 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 remote-base capability, allowing it to work into several distant repeaters on either the 6-meter or 70-centimeter bands, as well as having great simplex range on 52.525 MHz, the National Simplex Frequency for 6-Meters.

The 224.820 repeater is intended to be used as an "intercom" between the Pacific 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 PCEMA, 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 in the 150-MHz. commercial band) 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, continuous-duty station, so overheating should not be a problem.

The GE 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 4-cavity, Sinclair BpBr type, mounted horizontally in the bottom of the cabinet. The controller is an Arcom RC-210, built from a kit, and housed inside the repeater station.

Remote Base: The dual-band FM remote base consists of a Low-Band VHF GE Rangr commercial mobile radio, modified to operate on 8-channels in the 6-meter band, running 80-watts to a Cushcraft Ringo antenna mounted to the ice bridge on the building roof. There is a second GE Rangr, on the 70-cm band, with 13 UHF remote-base linking channels to other repeaters, and 2 UHF simplex frequencies (446.000 & 446.500). This radio is also used for the network link to
BeachNet when desired. The repeater shares a Comet CX-333 tri-band antenna with the 2-meter packet station that also lives at this site.

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.
