Service area map - Oly-Comm1 Repeater

This prediction is based upon typical equipment performance histories and the known terrain. Green and gold shading indicate areas of operation, depending upon specific transmitter power.  This map was generated with an arbitrary distance cut-off beyond about 100 miles. This UHF-FM system was designed from a regional-coverage perspective.

While this prediction is also based upon typical equipment performance histories, and the known terrain, actual performance exceeds the immediate Port Townsend area with coverage into a portion of east Sequim. 



Service Area Map - Oly-Comm3 (East Tiger) Repeater

This prediction is also based upon typical equipment performance histories and the known terrain. Field-verification will occur upon completion of construction and any updates will be posted here. Green and yellow tinting indicates mainly mobile (higher-powered) coverage. As with every radio system, "Your Mileage May Vary" so it is always best to plan for mobile operations first and foremost, and recognizing that hand-held radio coverage will be best-used in conjunction with localized mobile-commands events!

Coverage of the Oly-Comm1 system has been significantly improved with the addition of the DB-411B antenna. However, our desire to to provide solid coverage over more of the central Clallam County region, will be best served with the addition of a fourth repeater.  This projection is based upon a theoretical installation at either Striped Peak (a common site for solid communications in this part of Clallam County) or at Mt Gunderson.   For closer looks, "Right Click" either map and open in a new tab.



Beyond the coverages, listed above, of Oly-Comm repeaters 1, 2 and 3, there are other GMRS repeaters providing service for the Puget Sound and Olympic Peninsula region.  These are also operated by visionary individuals interested in the well-being of residents in the region.  Similar predictive mapping, for those systems,  will be displayed here as the necessary details become available.  Regional disaster-response repeater operators have a strong sense of helping-when-they-can and are happy to partner together in times of need.

The personal and business usage of the GMRS continues to grow and evolve.  Yes, business usage remains completely legal, it is only the licensing of business entities that was discontinued in 1987.  Please refer to permitted usage here and prohibited usage here.

Another "hot topic" of discussion is whether the "linking" of GMRS repeaters is "legal" or not.  A shallow reading of some FCC rules seems to say no.  A more thoughtful investigation seems to indicate rules ambiguity that needs to be addressed.  We will strive to add more information here when it becomes available.  95.1749 outlines some restrictions, BUT this is apparently not the whole story.  Some interesting (read technical and possible rather deep) discussion is here. Stay tuned...
