(Current as of 4/2/19)
With material help from Randy (W3RWN) and labor from Casey (AE7SL), the Puget Sound Repeater Group has installed its test DMR repeater at Capitol Park. This repeater is linked to and carries the core PNW-DMR (Pacific NorthWest DMR Group) talkgroups.
For more information on the PNW-DMR network, please visit their 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 new so its not in the existing codeplugs which you can download from the PNW-DMR website.
RX 440.775 / TX 445.775 (+5.0) Color code 2

The equipment for this repeater is a Yaesu DR-1X operating at 20 watts into a modest gain antenna. The digital modem is a Micro-Node Teensy-MMDVM connected to a Raspberry Pi 3 running MMDVM-Host and DMR-Gateway to interconnect to the PWN-DMR 2-slot gateway, known as Rex. This is not the final configuration but one the group could launch quickly, and help us gain more information to inform our final equipment choices.
We have been really pleased with the initial coverage reports. Please let us know how you find the coverage. We are currently running 5 watts, but that was a configuration mistake and it will shortly be set to 20 watts which will probably be the final setting for the test repeater. Send questions and observations to email@example.com.
*Also please note that PNW-DMR is in the process of moving their web presence to a new hosting site and that some of the URLs referenced above may change in the future.
