I am new to DMR and I don't quite understand how the Brandmeister and DMR-Marc networks link into local repeaters, not talking about hotspots. I have some of the W8CMN/Mi5 repeaters and local talkgroups programmed into my radio and that's all fine, but based on the Mi5 call history page I assume I can link into other non-Mi5 talkgroups? Is the W8CMN network MARC or BM or can it link to both? If it's a MARC network doesn't that mean the owner chooses which outside TGs can be used? On the W8CMN webpage it lists the local talkgroup IDs (ie. 51,52,etc.) but most of those have a BM talkgroup listed also (ie. 21261,21262) so I assume that's how people from the outside can link in? That would make me think it's part of the BM network, but if that were the case, I assume all of the call history and live audio would be available on the BM site, and it's not.
