SeattleDMR.org - Supporting Seattle DMR users
The SeattleDMR is an amateur radio DMR network was created to provide a DMR service to the Seattle metro area community and also provides us with a platform for experimentation with this new medium. It is comprised of 3 repeaters in the Seattle metro area. They are supported by a bridge running HBLink3 and the HB_Bridge/IPSC_Bridge interface software. Please refer to the SeattleDMR.org Bridge Design for more details.
This presentation from May 2020 provides
an overview of the network, its motivation, and features that make it unique and
useful to our community.
| Repeater | Frequency | TX Offset | Color Code | Details |
|---|---|---|---|---|
| Seattle Central | 440.775 | +5.000 | CC2 | Capitol Hill, Seattle - WW7PSR - Sponsored by Puget Sound Repeater Group. See the PSRG DMR page for information on the first repeater in this network. |
| Seattle North | 441.025 | +5.000 | CC2 | Lake Forest Park Reservoir, north of Seattle - W7ACS - Sponsored by Seattle Auxiliary Communications Service |
| Seattle South | 440.975 | +5.000 | CC2 | Westcrest Park - W7AW - Sponsored by West Seattle Amateur Radio Club. Repeater ID: 310534. Latitude: 47.520925 Longitude: -122.34341 Locator: CN87TM85SA (map, sat, terrain) [NOTE: Not linked to other WSARC repeaters] |
This table is generally self explanatory, but the Link talkgroups deserve some explanation. These are intended to be dynamicly assigned to talkgroups gatewayed in from other DMR network 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 (880?).

These codeplugs include all the SeattleACS Analogue FM channels and a robust set of simplex and data channels.
Note: The repeater channels include CTCSS on receive where it is known to be enabled and we have personally tested that it works. This eliminates the occasional interference we frequently encounter on VHF and UHF here in Seattle's urban landscape.
Codeplug and relate files for the Anytone-878 supporting PNW-DMR and Seattle Core repeaters can be found here.
Codeplug and relate files for the Connect Systems CS-800D supporting PNW-DMR and Seattle Core repeaters can be found here.
Using pre-built DMR codeplugs:
I have created these brief instructions for those using the pre-built codeplugs above:

Creating Customized Codeplugs:
I have needed to create codeplugs that combine PNW-Digital DMR systems with
repeaters and frequency information from other organizations. I hate manual toil so I have created this procedure
using available tools, particularly the Anytone Config Builder, from
Andrew Dickinson, K7ABD and N0GSG's Contact Manager program for Windows.
Instructions for creating identical codeplugs for the Anytone and CS-800D with no manual entry can be found
here. This is the process I used to create the codeplugs
on this website and for Seattle ACS. Besides the community files from PNW-Digital, these files will be needed:
| Filename | Comment |
|---|---|
| Analog-ACS-addon.csv | Additional Analog FM channels for Seattle including the ACS VHF and UHF channels for voice and data (Winlink) in 4 separate zones |
| Analog-Merged.csv | The result of merging the ACS addon with the PNW-Digital analog list. This is an example of a merged file that is ready for upload to Config Builder |
| Digital-Repeaters-Seattle-addon.csv | Additional DMR repeaters for Seattle. This file needs to be merged into the PNW-Digital file. You add the rowe and then get the column content matched up |
| Digital-Repeaters-Merged.csv | This file is an example of the merged result and is ready for upload to Config Builder. |
| Talkgroups-Seattle-addon.csv | Additional talkgroups used locally in Seattle and supported by SeattleDMR.org and associated repeaters |
| Talkgroups-Merged.csv | This file is an example of the merged result and is ready for upload to Config Builder |
| merge-repeaters.py | This Python script with take 2 ConfigBuilder Digital Repeater spreadsheets and merge them. |
| merge-talkgroups.py | This Python script with take 2 ConfigBuilder talkgroup spreadsheets and merge them. |
