The Puget Sound Repeater Group has installed a DMR repeater at Capitol Park. This repeater is linked to and carries the core PNW-DMR (Pacific NorthWest DMR Group) talkgroups. Since then, two more repeaters have been added to the Seattle area and are operated as a cooperative network. See the SeattleDMR.org website for more details.
Resources
For more information on the PNW-DMR network, please visit their excellent website pnwdigital.net* for details on talkgroups, user technical guidelines, and operating best practices. If you are going to operate DMR in this region, please join the PNW-DMR notification group so you can receive operational notifications and be informed of network changes. If you have not operated DMR before, please take some time to read some of the information for first time users before keying up.
Also, Bob Stephens AF9W presented “An Introduction to DMR” at the 2019 Annual Meeting. Copies of his slides can be found by clicking the above link.
Finally, the PSRG Wiki includes a link to Tim WT1IM’s DMR Cheet Sheet.
Now the details so you can program your radios: Our repeater is not in the existing codeplugs which you can download from the PNW-DMR website.
More details on the PSRG DMR repeater will be found at SeattleDMR.org.

SeattleDMR.org Supported Talkgroups
This table is generally self explanatory, but the Link talkgroups deserve some explanation. These are intended to be dynamically assigned to talkgroups gatewayed in from other DMR networks on an as needed basis. We list them here and encourage their programming to allow us to quickly provide access to new or needed talkgroups from other networks without requiring radio reprogramming. The bridge will do talkgroup remapping of the original talkgroup to one of these dynamic talkgroup ids.

The PSRG repeater is a Motorola MTR-3000 operating at 65 watts (2/3rds of its rated power) into a modest gain antenna. The repeater currently connects to software (HBLink) running on a Raspberry Pi3 that provides the interconnect to the PNW-DMR system via its C-Bridge infrastructure. This repeater is operated as a experimental platform for digital voice repeater technology. We will continue to observe and evolve this repeater system as we learn more.
We have been really pleased with the initial coverage reports. Please let us know how you find the coverage. Send questions and observations to tech@psrg.org.
