PNW DMR MMDVM Talkgroup Matrix
for Managers, TG Appearances & Timers

Bridget, Suzy, Peter, Rex and Wes are alive, next to deploy will likely be Emma

The PNW MM's are an adjunct to and for the use of our c-Bridge repeater network.  The MM were not designed to be used for hotSpot to hotSpot users only.  While is is technically viable, we are not encouraging such use at this time.

Be sure not to put your hotSpot on any repeater output or input/output frequency as it likely will result in looping and render the server useless and busy out a timeslot on the c-Bridge.

Rex is experimental for use of 2 slot devices such as MMDVM based repeaters.  Most hotspots are single slot devices so the c-Bridge programming is different for the hold-off timers.  All other MM servers have all talkgroups the same timeslot, 1 or 2, depending on the HotSpot.

TAC 2 and TAC 8 have been added.  TAC 8 has no connections to any c-Bridge repeaters so it is the primary MM-to MM QSO talkgroup. Talkgroup 9 is no longer supported between MMDVM servers.

How to use the matrix:  Find the repeater column and then scan down to see which talkgroups are listed.  Or to find where a talkgroup may appear, locate the talkgroup of interest and scan across for repeaters that carry that talkgroup.  The entry at the intersection tells you if it is carried full-time (F) or if it is on PTT (P).  If a "P" then the numbers indicate how long the talkgroup is active after any local kerchunk or key-up is initiated.  The number after the forward slash (/) indicates how long it will hold off most other talkgroups on that timeslot after the last local kerchunk.  These timers and MCT's help to insure that an active local talker will not lose that talkgroup.

A Kerchunk will connect a TG immediately if their is no active talker.  HOWEVER: if there is an active talker, at the time of your PTT or Kerchunk, the talkgroup traffic will not be connected or heard by you until the current talker unkeys and the next talker keys-up.

∞∞ indicates that a talkgroup may not be available to all managers, in your area or may come with restrictions on their use.  These conditions are not necessarily set by PNW but may be part of an agreement with other organizations which control their talkgroups appearance, distribution and/or use.

Master Control Talkgroups or MCT's and HO's (hold-offs) may be implemented to provide more control over the timeslot than the timer based "hold off's".  New managers are now being programmed for active local repeater users MCT control and relying on Hold-off timers far less but some HO's may be coded as a convenience to users, possibly: I-5 1,ID 1, Oregon 1 , PNW 1/2, PNWR 2 and/or WA 1&2.  So options are Yes/No/Partial for both MCT's and Hold-off timers being coded into each manager.

Typical PTT talkgroups on the MMDVM servers have an "on-timer" for 15 minutes and most have "hold-off timers" for 2 minutes.  Not all hold-off timers for the PTT TG's may be in place.  Some TG's have a bare minimum as indicated by "P15/0" as they are quick to program and somewhat useable for PTT purposes by repeaters that have not expressly requested those particular talkgroups.  In other words, the talkgroup is programmed into the manager and usable via PTT but the more involved programming to implement the hundreds of hold-off timers, has not been implemented.  So it is probable that other talkgroups may capture the slot and stomp on these "zero" talkgroups, especially the full time talkgroups.  Somewhat of an approach that "it is better than nothing".

Columns:  F/y = Fulltime / Hold-off Timer (y min or mct)
Columns:  Px/y = PTT On Timer (x min) / Hold-off Timer (y min)
Columns:  Pr/y = PTT On Timer (x min) r = Receive Only / Hold-off Timer (y min)
Columns:  Px/0.f = HO's only for the fulltime TG's for minimal control (.f = fulltime)
~~ = Confirmed working while Bell VHF manager is being built out

Blank = No appearance of TG on manager
tbd = no decision on this talkgroup on this manager
Question Mark = unknown status, incomplete programming, pending adoption or otherwise potential changes tbd
+ = Some hold-off timers are in place but incomplete
programming
MCT controls = 55 or 59 min On / 15 or 29 min Off and may or may not have supplemental HO's for fulltime talkgroups for better experience

This matrix is now the baseline or controlling document to determine all interactions on each manager listed in this matrix.  If you have any issues with talkgroups, stomping on other talkgroups, etc, please look to this chart, determine what should be the listed action and then armed with that information, report issues.
