Pacific Northwest DMR
Washington EmComm and Public Service Talkgroups

 

DRAFT: This Talkgroup plan has been adopted by nearly all WA repeaters

 

The Washington PNW DMR network of repeaters actively support EmComm and other public service groups that wish to use our Washington repeaters.  Any scheduled organized group with a public service activity is welcome.  Your event will have priority on our talkgroups over other normal network user activity.

Please contact us to reserve dates and times as well as to discuss specific needs.  This will enable PNW DMR to provide the most efficient resources and notify our members of upcoming events to reduce inadvertent use during your event.

PNW DMR (with the addition of Rattlesnake Ridge (North Bend) VHF repeater will provide 95% coverage of the I-90 travel corridor to supplement our current 95% coverage of the I-5 travel corridor in Washington and well into British Columbia and south to Eugene WA.  While Oregon and British Columbia are not officially in our Washington EmComm plan, they still are available to use with many interconnected talkgroups as they are officially a part of the PNW DMR network.

We can likely provide you with single or multiple repeaters, local, county wide, intra-county or statewide services.  By default our PS 2 talkgroup is set-up to operate independently but public service event personnel are easily able to add more repeaters as needed, in the field and on the fly.  With prior arrangements for scheduled events, we are able to implement unique setting that will set-up our repeaters to suit your needs.

PS 2 is the primary public service talkgroup as it can be scaled up as needed to provide coverage into more and wider areas. 

PS 1 is a secondary talkgroup available if needed but it lights up almost all Washington state repeaters so PS 1 is more likely to be used in a statewide emergency.

PNW DMR has it's own direct connecting MMDVM server to support hotSpot deployment and use at stationary locations or in the field via convenient tethering to cellular phones or other Internet sources in tandem with repeaters or use in areas not supported by RF repeater coverage.  Generally not the most robust, dependable approach due to Internet connectivity but bring essential operational advantages to areas that do not have RF repeater coverage.  We also have 7 other MMDVM services to support other aspects of our network operation that could provide essential back channel operation if the repeater network is busy or congested.

SMS or Text Messaging can also be available.  At this time, it's use is problematic due to many non Motorola radios not implementing SMS support according to their standard.  PNW DMR is working on determining how to best support most radios rather than only MotoTRBO hardware.  This is an ongoing effort.

PNW DMR is closely associated with HamWAN and their statewide microwave IP backbone and we have been able to bring HamWAN to sites where PNW DMR has repeaters.  Many of our repeaters are now using the HamWAN backbone and all our Networking services on the West side of the state is on the HamWAN microwave backbone as are 6 of our repeaters.  We have 3 repeaters on the East side with HamWAN network support and we are supporting and funding the effort to bring HamWAN backbone over the Cascades to Yakima in a major effort to bring all of HamWAN onto a single RF backbone.

PNW DMR also is capable of supporting a Brandmeister talkgroup (TG ID 31771) on a full time basis if needed.  Brandmeister brings several benefits to the table with little downside.

PS 1 and PS 2 talkgroups are designed to function in an emergency.  Nothing must be enabled or programmed ahead of any event.  So these services are available at any time.  Of course any talkgroup can be used for an emergency.  We suggest Washington 1 or PNW 1 (programmed full time on most Washington repeaters) as the initial talkgroups of choice as all our users have these talkgroups and generally are listening via scan or Rx Groups.

 

POTENTIAL PNW EMCOMM Talkgroups

Talkgroup Timeslot 1 Timeslot 2 Timers Brief Description
PS 1 3190   Full Time Full time WA statewide with 2 hour timers to hold-off other networked traffic
PS 2   103190 PTT 1 hour PTT timer, 1 hour to hold-off timer local repeater normal networked traffic
Local 1 3181   Full Time Next highest priority talkgroups.  Local 2 can be linked to other repeaters for broader or wider area coverage as needed if planned for in advance.  Typically, the locals operate independently of other repeaters and can co-exist with or supplement an active public service event.
Local 2   3166 Full Time
PNWR 2   31771 Full Time Standard full time talkgroup on PNW with Brandmeister access
TAC 1-3   8951-8953 PTT Potential use for back-channel point-to-point communications such as EOC to EOC, Hospital to Hospital, etc
Washington 1 3153   Full Time Auxiliary EmComm Talkgroup (most DMR users are listening here)

 Not all WA repeaters carry PS1 and PS 2 talkgroups; see our PNW Talkgroup Matrix
