W7BU, as a club, owns, operates and maintains four repeaters (with plans for a fifth) which cover the Clatsop County Area. All repeaters are open repeaters for use by the general Ham community. Standard offset values and directions are used on SEARC repeaters, all SEARC Repeaters use the same CTCSS tone of 118.8 Hz, with the exception of the 440.925 repeater on Megler Mt., which uses 100.0 Hz.

Click on a repeater below for more information on that repeater, and to display a link to go to a page devoted to that repeater only.

The '45' [W7BU/SEARC]

Our main repeater, the “’45”, operates on a frequency of 145.450- MHz and is located on Megler Mountain (appx. 1,300 feet), just across the river from Astoria, Oregon.

In the coverage plot for the 145.450 (Megler) Repeater below, contributed by Frank Wolfe [NM7R], the parameters are selected conservatively to represent the "worst case" for normal operations. Having the plots a bit pessimistic is better for planning than a wildly optimistic picture that gives false hope for coverage that really doesn't exist, encouraging those weak in-the-mud signals we all hate to deal with.

The the outer area on the plots represents a "plain vanilla" (3 dBi) mobile vertical at 1.5 meters above the ground, with 40-watts. This is a good representation of a "typical" mobile. A base station would probably do much better, but it is hard to characterize a "typical" base station.

The inner (darker) area represents a "typical" HT, with a -2 dBi antenna, also 1.5 meter above ground and 4-watts.

Note: There is another 145.450 MHz repeater just on the other side of the Coast Range (North Plains,in the Hillsboro area) - it has no PL tone. The two repeaters, despite being so close, do not seem to interfere with each other at all. Just be aware that when you cross over to "the other side", you may get a repeater you didn't expect! (You can tell the difference immediately - W7BU's repeater has a simple "bloop" courtesy tone after the station ID, and the other repeater has a "bo-o-o-i-ing" tone, like a cartoon spring's sound)

The '76' [W7BU/SEARC]

Our second repeater, the “’76”, operates on a frequency of 146.760- MHz, and is located on Nicolai Mountain (appx. 3,000 feet), approximately 20 miles east of Astoria. This repeater has wide coverage, and can be heard, if not always hit, from as far away as Olympia & Gig Harbor, Washington and Eugene & Mt. Hood, Oregon.

The '74' [W7BU/SEARC]

Our third repeater, the “’74”, operates on a frequency of 146.740- MHz, and is located on Asbury Ridge above Arch Cape, Oregon (appx. 2,400 feet).

The '925 [W7BU/SEARC]

Our fourth and most recent acquisition, the "'925" repeater, operates on a frequency of 440.925+ MHz with a CTCSS Tone of 100.0 (different than the remainder of our repeaters), and is located in Washington State, across from Astoria (on Megler Mountain) at approximately 1300 feet. Formerly owned and operated by Brad Gulleff [N7BAG] and purchased from him in October of 2009, this repeater covers south to Canon Beach, Oregon and north to Long Beach, Washington It also works well along US 30 to Longview. This repeater has a frequency agile remote base on 2M/440/220. It also has IRLP and Echolink capability.

The '49 [WA7VE/STARS]

Owned by the City of Seaside and operated by the Seaside Tsunami Amateur Radio Society and bearing their club callsign "WA7VE", this repeater operates from the Seaside City Water Plant on top of Peterson Point, just south of Seaside. This is a new repeater as of late February, 2009. It operates on a frequency of 145.490- Mhz, with a PL tone of 118.8, and is an open repeater. No autopatch or linking at this time.

Local Packet System

While technically not a repeater, this seemed like the best place to add our local packet node(s) information

Packet_Local_Map

OCRG System

While not our repeaters, the Oregon Coast Repeater Group system of repeaters is close enough to us, and actually overlaps some of our coverage, so some information on them is given here, supplied As-IS from the OCRG. This is new information as of 19 January 2009. The OCRG main website is located at http://www.ocrg.org. A link to a visual aid of how the repeaters are linked is below.

Rockaway Beach 442.750 (on)
Mt. Hebo 440.900 (on)
Cape Meares 147.160 (normally off)
Otter Crest Newport 444.750 (on)
Lincoln City 443.750 (coming up this winter, on all the time, IRLP node)


New UHF Linking - Mt Hebo (W7GC) to Herman Peak (Florence - W7FLO)
 
The 440.900 uhf repeater on Mt Hebo may be linked at times to Herman Peak near Florence for testing.  The signal path is being optimized and a new antenna was recently installed at Herman Peak.  This system will be able to reach additional linked repeaters on the southern Oregon coast and Willamette Valley, including Coos Bay, Eugene, and Roseburg. Contact N7HQR, daron@wilson.org , for more information.

Three of the four W7BU repeaters (146.760, 145.450, and 146.740 are normally linked together, although they can be separated out individually if need be during an emergency (for instance, to facilitate north-south traffic on one and east-west traffic on another).

The fourth repeater, 440.925, which encompasses a standalone 2M/440/220 frequency agile base station, formerly owned by N7BAG and located on Megler Mountain along with W7BU's 145.450 repeater, has been purchased and transferred to W7BU ownership, which adds the the ability to link directly into the Portland metro area as well as all the way up to Olympia, currently only doable by linking into the BeachNet System (below).

The entire system is currently also linked into a further repeater system owned and operated by Jay Shepherd (W7FBM) - the main repeaters of which are on Wickiup Mountain (appx 2,600 feet) using the frequencies of 146.660- MHz and 444.7750+ MHz, and occasionally linked in is the 146.860 MHz repeater (owned and operated
by Pacific County ARC) - again, all these repeaters use the same 118.8 Hz PL tone. In addition, we can be linked with the BeachNet Repeater System in SW Washington, covering the Long Beach Peninsula and all the way up to Olympia, Washington - this is usually done during the Monday night Clatsop County ARES et (1900 hours) and the Thursday night Pacific County ARES Net (1930 hours).

Other local repeaters can be found on these .pdf format maps:
Clatsop, Pacific, & Grays Harbor Counties Repeaters
Lincoln & Tillamook Counties Repeaters
Oregon 2M Repeaters
Oregon 70cm (440 Mhz) Repeaters

Here are .kmz overlay files for Google Earth® or Google Earth Pro® for Oregon Repeaters and Washington Repeaters

Repeaters for other frequencies and/or areas of the United States & Canada can be found at http://www.eham..net
