Expanded Information

The PNW DMR Network is a system of open use DMR repeaters located in the Pacific Northwest. The PNW c-Bridges currently supports 40 plus MotoTRBO repeaters with 29 plus in Washington, 10 in Oregon and 1 in Idaho. We also have deployed several c-Bridges, an echo server and 8 MMDVM servers for additional repeater and hotSpot support linked via HamWAN, a private RF based IP backbone network for Hams. Where possible, our repeaters are connected to HamWAN with some repeaters having dual IP sources with failover protection to insure the most robust connections during times of greatest need.

This network enables the use of a single local area repeater for a QSO or EVERY repeater on the network, depending on the talkgroup selected. Each repeater can support 2 simultaneous conversations or upwards of 50 conversations network-wide. Users are empowered to talk locally on a single repeater or to thousands worldwide. Think smallest footprint needed to support your QSO. Understanding how the talkgroups are designed to work is important before hopping onto the network.

New users of PNW DMR repeaters should read our Welcome Page. Our primary web pages are available via links on the green banner at the top of all pages throughout this website. Otherwise, click on the Links to to see more of our web pages.Hams new to PNW DMR or DMR generally, you should read the Quick Start and/or Best Practices pages. Check out the Repeater Location Map. The affiliated Oregon SAR repeaters operate differently, so please consult the Oregon Users Guide and/or read more . You may also catch us on our Not-A-Net Gathering Wednesday evenings on the Washington 2 talkgroup at 1900 local. The Gathering was created in part, to assist our newest members with basic DMR information. So please join us there each week.

Policy update: All regular users of the PNW DMR Network (excluding visitors or through travelers), are requested to become members of the PNW DMR network by registering at our PNW groups.io subgroup. Members may use our resources freely according to our published best practices and user guides. We encourage our repeater users to become members but we do now require the users of our networking services, such as hotspots and IPSC to become members. Read our policy update to understand the difference and why we now would like everyone to join our IO group. Our repeaters are open use while our networked services requires membership. There is no cost to join and all services are free. Users who do not join our IO group will be asked to join. Ultimately PNW DMR may require that you join or your networked services may reduced to repeater use only. Please join our IO group!


AFFILIATED DMR Networks

The Oregon SAR Group has affiliated with PNW DMR. Their repeaters are operated primarily for Search and Rescue operations. Routine QSO use is limited to 10 minutes generally for PNW DMR members, visitors and travelers (if no active SAR events). Please read the Oregon SAR Group Users Guide, join their IO Group and read their Facebook Group before using their repeaters. Contact Loren, KB7APU for additional information. This is a negotiated agreement between PNW and the Oregon SAR Group for PNW members and the traveling and visiting ham to use the Oregon SAR repeaters.

BC-TRBO network in British Columbia Canada and the HKS c-Bridge network and repeater (Sultan WA/Haystack Mtn) have also affiliated with PNW DMR. There are no restrictions in their use.

PNW DMR has select Brandmeister talkgroups but we are not a Brandmeister network. We also have some other specialized assets including Polly, our echo server parrot, multiple direct connecting MMDVM servers supporting hotspot, MMDVM repeaters and high power DMR simplex stations.

Many of our repeaters and networking assets are linked via HamWAN's RF backbone. This private IP network is preferred as their services are most dependable and better supports UDP voice packets while the public IP network manipulates UDP which lowers voice quality and increases BER. We are working with HamWAN to expand their network coverage while expanding our radio links to their private network for more robust IP connections free of UDP machinations which typically are worst at peak use times.


EmComm, ACS, ARES, RACES and Public Service Use

PNW DMR also wishes to affiliate with and/or provide our services to, EMCOMM type groups such as RACES, ARES or ACS and other independent EMCOMM, public service groups or ham clubs that support their communities. PNW DMR has available specialized talkgroups for Washington that are able to support emergency communications as well as public service events while still allowing much of our regular activity to continue without interruption to our regular users.


Network Growth

PNW DMR is growing. We expect that we will have about 90% of the Washington population base covered by summer 2019. We welcome clubs and individual groups to explore DMR and to join us. We will also support local efforts by interested area hams who wish to get a DMR repeater deployed onto the PNW network in their area. We also support MMDVM based repeaters and encourage them to join the network as well but are mindful that MotoTRBO repeaters are the most robust hardware for wide area RF coverage.

If you know of any hams or ham clubs in the Pacific Northwest interested in DMR and they do not know of our DMR network, please pass along our web address (www.pnwdigital.net) or Email address (admin@pnwdigital.net).
