I have stumbled on this repeater in Dutchess County.
I was able to get into it and have a conversation with several people on our HVDN talkgroup. You can pretty much access any Brandmeister TG at the moment, but the word is that once Winter is over, the SYSOP may set it up like the rest of his (NY4Z) repeaters in the NYMETRO DMR Network.
Here are the details: (Note: Brandmeister TG's are on TS-1)
