BeachNet System

User Reference Manual

BeachNet Repeater System User Information Guide v13.0 (05/14/11)

    The BeachNet system is located in Pacific, Grays Harbor, Wahkiakum and Thurston Counties, in the southwest corner of Washington, and Clatsop County, OR. As of May 2011, the network consists of eighteen repeaters and six remote receivers at seventeen sites. The main network comprises six 2-meter, one 1.25-meter and eight 70-centimeter repeaters continuously linked together. A transmission received on any of these repeaters is heard over the entire system. Most of our repeaters use a CTCSS (PL)

    tone of 118.8 or 82.5 Hz, and standard offset. The system roughly covers a rectangle with corners near Kalaloch, WA (NW), Seaside, OR (SW), Longview, WA, (SE), and Tacoma, WA, (NE).

    Although both 2-meter and 70-cm transceivers are necessary to access the entire

    network, nearly complete

    system utility is available on

    either band.

    Loading the entire frequency

    list into adjacent radio

    memories makes it a simple

    matter of stepping “up” or

    “down” to remain connected

    to the network via the best

    “port”, as the user moves

    around the area. All

    communities and major

    roads within this area enjoy

    ready access on VHF, UHF

    or both with a normal mobile

    “Ham” rig. Handheld access

    is available in most

    populated areas.

    The North Cove 444.400

    and KO Peak 224.040

    repeaters can be linked into

    the network, but normally

    operate as stand-alone

    machines. We also host a

    dedicated IRLP node

    repeater in the Long

    Beach/Astoria area on

    444.925, which is also not

    linked to the network.

Please Use and enjoy the BeachNet system. That’s why we built it!

BeachNet Operational Policies

    Any appropriately licensed Amateur Radio Operator, not otherwise excluded, is welcome on the BeachNet Repeater System, provided they abide by the following...

    1. Observe and obey all FCC Regulations with respect to the Amateur Radio Service, as contained in Title 47, Part 97, of the Code of Federal Regulations (CFR). Lead by example.

2. Respect all Amateurs using the BeachNet Repeater System, and strive to encourage the

    participation and enjoyment of others. Leave a pause between every transmission to allow another user to join in. Extend the hand of friendship. We are all part of the Amateur Radio Fraternity. This two-way radio hobby is a lot more fun if there are other Hams to talk to.

3. We live in an area dominated by a tourist economy. Make our guests feel welcome. Be the

    friendly, helpful Ham they talk about when they return home.

4. Help make Amateur Radio in general, and the BeachNet Repeater System in particular, a

    pleasant place to hang out. You do not have to "like" every other Ham, but be civil and polite, even friendly. Keep it light. Keep it fun. If you can't say something nice, don't say anything at all.

    5. Emergency communication has absolute top priority at all times. The best way to be ready in an emergency is to become familiar with the resources at hand. BeachNet is one of those

    resources. The more familiar we all are with its strengths and limitations, the more value our community can derive from the Amateur Radio Service when it is needed most.

6. Jamming and deliberate interference are to be ignored. Do not talk to a jammer on the air.

    Do not talk about a jammer on the air. That is exactly the recognition they want. It is possible talking to the "suspect" could be considered "entrapment", making prosecution more difficult. The FCC has successfully prosecuted jammers in the past, with license revocation, fines and/or jail time. If you hear anyone abusing the system, and have specific information as to time, place or identity, please contact a control operator by telephone or email. If presented with such an issue, the owners, licensees and control operators will handle the situation.

    7. Control Operators will be designated at the sole discretion of the system owners/licensees. Only Control Operators are authorized to send Dual Tone Multi Function (DTMF) "Touch Tone"? signals over the system to command the repeaters, remote bases, auxiliary receivers and other components that comprise the BeachNet system. Except as explicitly authorized by a

    Control Operator, Owner, or Licensee, no other user shall send DTMF control tones over the BeachNet System. Any attempt to "Hack" a repeater system by an unauthorized person is considered a very serious offense within the Amateur Community, equivalent to attempting to pick the lock in order to break into the home station of another Amateur.

    8. The BeachNet Owners, Licensees and Control Operators retain the authority, expressed in 97.205(e), to exclude any individual from using the BeachNet System.

    Olympia

46-58-22N 123-08-14W 2730 FT

    The Olympia repeater is located on Capitol Peak, south of the city of Olympia and west of the Olympia airport.

Frequency: 444.950

    Transmit Offset: +5 MHz

    CTCSS: 118.8

    The repeater consists of a GE MASTR-II 110-watt continuous duty base station chassis, Phelps-Dodge 6-cavity duplexer and Diamond X-510 antenna (inside the fiberglass radome from a commercial “Stationmaster” antenna), and fed with 120-feet of LDF5-50

    7/8” hardline. The link uses a modified GE Rangr mobile radio running 10 watts through 100-feet of LDF4-50 half-inch hardline to a 10.2 dB yagi pointed at KO Peak. The packet bridge (see below) uses two GE Mastr-II 40-watt mobile radios and a dual-port controller. All four transmitters are fitted with 2-section isolators and bandpass cavities. The main antenna is shared by the repeater and both packet radios using a 4-cavity VHF combiner and a VHF/UHF diplexer.

    The repeater covers eastern Grays Harbor County, most of Mason and Thurston counties and parts of Lewis County, as well as much of southern Puget Sound to well north of Tacoma.

    Packet Radio: The station incorporates a dual port packet bridge between the 145.63 coastal “District Three EOC Net” frequency, and the 145.05 Puget Sound net frequency.

    To use the bridge to pass packet signals in either direction, digipeat “via n7ujk-10”. For

    digipeating on 145.63, use “via n7ujk-8”, and to digipeat on 145.05 use “via n7ujk-9”.

    The 3000-foot elevation makes this a strategic relay point for this popular digital mode.

    Doyle Wenzel (N7UJK) of Aberdeen is the owner, licensee, and site custodian. He has complete control operator authority concerning this site. He is an authorized BeachNet

    control operator, permitted to use the KO remote base. Doyle is the local contact in Grays Harbor for the BeachNet system.

    Neilton

47-23-22.7N 123-52-01.2W 2100FT

    The Neilton site is located in northern Grays Harbor County, at 2100 feet, overlooking the town of Neilton and Lake Quinault. The repeater covers highway 101 from north of Kalaloch, south to Hoquiam, as well as Westport, and much of western Grays Harbor County. The repeater is a GE MASTR-II 110-watt continuous duty base station with a Sinclair BpBr duplexer. The linking path to KO Peak is 66 miles, unobstructed line-of-sight. The link radio is a GE Phoenix running 10 watts to a Cushcraft 10.5 dB gain yagi about 65 feet above ground level.

Frequency: 444.700

    Transmit Offset: +5 MHz

    CTCSS: 118.8

    Packet Radio: The NEILTN Packet node operates on 145.630, covering western Grays Harbor County as part of the District Three EOC Packet Network. The repeater and packet station share a dual-band antenna.

    Doyle Wenzel (N7UJK) of Aberdeen is the site custodian, and the only one with physical access. He has complete control operator authority concerning this site. He is an authorized BeachNet control operator, permitted to use the KO remote base. Doyle is the local contact in Grays Harbor for the BeachNet system.

    Cosmopolis

46-56-00.6N 123-44-02.5W 550FT

    The “Cosi” repeater is located on Cosmopolis Hill at about 550 feet elevation. This is just a mile or two northwest of the junction of Highway 101 and State Route 107 (the “Montesano cutoff”), overlooking Cosmopolis and Aberdeen. The coverage area

    includes Ocean Shores, Hoquiam and the Chehalis River Valley, east to Elma. The coverage also extends south down 101 for several miles to the Pacific County line, and north into NW Grays Harbor County.

Frequency: 145.390

    Transmit Offset: -600 kHz

    CTCSS: 118.8

    The purpose of this repeater goes beyond just augmenting our system coverage on highway 101, although it is in a very strategic location as far as that goes. The installation primarily provides a link between Grays Harbor County and Pacific County for emergency communications. The BeachNet system then provides a further path to

    Camp Murray, the Washington State EOC. It also offers 2-meter coverage into Grays Harbor. “Cosi” has good tactical coverage within Grays Harbor County even as a stand-

    alone repeater, reaching the major cities of this coastal county quite well.

    The repeater comprises a GE MASTR-II 100-watt mobile chassis duplex conversion running about 40 watts, a Wacom BpBr duplexer and a GE Rangr 10-watt link radio. The controller is mounted in a metal project box with basic manual controls and there is an Astron power supply. The entire station is screwed to a chipboard panel on a wall inside the building. One site constraint due to limited space is that the entire repeater has to be mounted to the wall with less than a foot of overhang. The main antenna is a Hustler G6-270 6-dB gain dual-band vertical mounted part way up the tower, and shared by the repeater and link using a diplexer, fed with LDF5-50 7/8” hardline.

    The system link can optionally be shifted to (one of) Minot, Neilton, Aberdeen or Olympia sites, providing intra-County VHF/UHF interoperability for emergency relief communications. In an emergency situation, these repeaters would be disconnected from BeachNet.

    Doyle Wenzel (N7UJK) of Aberdeen is the site custodian, and the only one with physical access. He has complete control operator authority concerning this site. He is an authorized BeachNet control operator, permitted to use the KO remote base. Doyle is the local contact in Grays Harbor for the BeachNet system.

    Minot

46-53-29N 123-25-01W 1730 FT

    The Minot site is located a few miles south of Elma, and west of Centralia at a height of 1730 feet.

Frequency: 444.050

    Transmit Offset: +5 MHz

    CTCSS: 118.8

    The repeater covers eastern Grays Harbor County from Hoquiam to McCleary on Highway 8. Coverage extends along Hwy 12 to Chehalis. Pacific County also has coverage from Raymond north and east.

    The repeater consists of a GE MASTR-II 110-watt continuous-duty base station chassis, with a Phelps-Dodge 6-cavity duplexer. A GE Mastr-II mobile radio running 10 watts to a pair of phased 10.5 dB yagis pointed at KO Peak makes the network link connection. The repeater antenna is a dual band vertical (shared with the MINOT packet node), about 60 feet above ground level on the tower. The packet radio is also a Mastr-II mobile. All three transmitters are fitted with dual-section isolators and bandpass cavities.

    Packet Radio: The MINOT Packet node operates on 145.630, covering central and eastern Grays Harbor County, as part of the coastal District Three EOC Packet Network.

    Doyle Wenzel (N7UJK) of Aberdeen is the site custodian, and the only one with physical access. He has complete control operator authority concerning this site. He is an authorized BeachNet control operator, permitted to use the KO remote base. Doyle is the local contact in Grays Harbor for the BeachNet system.

    North Cove

46-43-52.6N 124-02-42.9W 400FT

The North Cove site is on the ocean bluff, above “Wash-away Beach”, just west of

    Tokeland, WA, at a ground elevation of 400 feet. The shared, dual-band Hustler antenna is 130 feet up the 140-foot tower. Other than the antenna, the two repeaters operate independently, with the only audio connection between them via the KO Peak site. The separate links with KO Peak use 10 watts to individual 10.5 dB gain yagis for the 30-mile line-of-sight path.

Frequency: 145.310 444.400

    Transmit Offset: -600 kHz +5 MHz

    CTCSS: 118.8 118.8

    The VHF rack-mount GE MASTR-II repeater chassis was salvaged from the Ilwaco 146.860 repeater when that machine was replaced. The power amplifier has been upgraded and a new controller fitted. The Sinclair Hybrid-Ring duplexer was salvaged (and rebuilt) from the Nicolai 146.760 repeater when it was replaced due to extensive rodent cable damage. This is an example of equipment that was considered junk due to defects or damage, which has been repaired and returned to service.

    The North Cove VHF repeater provides excellent mobile coverage from Bear River at the south end of Willapa Bay, along Highway 101 on the bay shore, to South Bend. It also covers the Tokeland, Grayland and Westport areas along the coast between Willapa Bay and Grays Harbor. It “looks” right down the ocean side of the Long Beach

    Peninsula, providing coverage on the beach north of the Cranberry approach.

    Remote Receiver: To augment coverage deficiencies due to the 400-foot elevation of the site, a remote receiver is located on Naselle at 2000-feet. Use the 145.310 frequency and standard 600 kHz offset, but change your PL tone to 114.8 Hz to

    access the Naselle receiver.

    The UHF repeater is a GE MASTR-II mobile chassis conversion with an internal controller and a 10-watt Motorola link radio. The coverage is less extensive than the VHF machine, which is interesting considering the shared antenna. The UHF machine normally operates as a local stand-alone, although it can be linked into the network when desired.

    South Bend

46-41-44.1N 123-46-24.1W 1300FT

    This site is just across the Willapa River, on Holy Cross Mountain, northwest of South Bend, WA and southwest of Raymond, WA.

Frequency: 147.340 442.675 224.820

    Transmit Offset: +600 kHz +5 MHz -1.6 MHz

    CTCSS: 82.5Hz 118.8Hz 82.5Hz

    The Holy Cross 2-meter and UHF repeaters are normally linked together and to the rest of the BeachNet system. However, the two machines can be separated, allowing one or both to operate stand-alone. The network link can be switched to either, or neither, as needed.

The 224.820 repeater operates separately. Although normally linked to BeachNet, it can

    be separated and used for other tasks.

    The coverage of both repeaters is excellent in the South Bend-Raymond-Menlo Valley area, and includes the north end of the Peninsula, Highway 101 as far south as Bay Center, and north to the Pacific/Grays Harbor County line.

    The UHF repeater normally transmits PL (118.8 Hz). The 224.820 repeater transmits PL (82.5 Hz).

    The Link radio is a GE Mastr II mobile chassis running 5 watts to a 10 dB yagi antenna for the 20-mile line-of-sight path to KO Peak. The link can optionally be switched through the Naselle site if desired.

    There are plans to add a future repeater at this site, operating on 224.820 MHz (82.5 Hz PL). The projected commissioning date is June, 2011.

    Packet Radio: The HOLYX Packet Node (145.630) is co-located, using a dedicated antenna at the low position on the tower and two bandpass cavities.

    The coastal District Three EOC Packet Net is on 145.63, providing VHF packet coverage to most areas within the BeachNet footprint. In addition to a network of

    strategically placed Packet nodes to relay your signal, there are Winlink RMS stations to allow you to send and receive Internet email over your packet station, and dual-port bridge stations to allow you to connect to other packet networks on other frequencies. Ask on the air for information, or visit the BeachNet website at:
