I'm fairly new to DMR, but with my background in trunking, I thought I had a good grasp of talkgroups. Maybe not so much.
Here's a question for the DMR experts here...
Due to my location, I have not been able to reach any of the DMR repeaters around me directly with my handheld MD-380. As a solution, I recently purchased a SharkRF OpenSpot and have since been able to access several of the wide-area talkgroups, such as TAC310, 311, and SEast. Unfortunately, however, I have had no luck at all trying to access a number of other talkgroups.
I suspect that this might be due to the different types of DMR systems (DMR-MARC, Brandmeister, etc) but the differences aren't real clear to me. In particular, there are three local/regional talkgroups that I have been unable to access - all are networked among numerous repeaters:
WNC (talkgroup 27600) - linked through 6 or 7 repeaters, but nothing heard via OpenSpot
NCPRN (talkgroup 2) - linked across several states, but when I monitor this TG, I hear hams from Ohio, Indiana, New York, etc. - nothing from NC or TN.
NAmerica (talkgroup 3) - obviously linked, but nothing heard via OpenSpot
I'd like to be able to use these (and other) talkgroups, so what are the rules on which talkgroups I can access and which I can't when using the OpenSpot? Is there a list somewhere?
Thanks in advance for suggestions.
