While there isn’t a whole bunch of DMR activity in the New England area, one of the Talkgroups that is fairly active is 98006, which is the AMSAT Talkgroup. That DMR Talkgroup has been bridged over to the DSTAR world.
Simply link your DSTAR radio into one of the XLXSAT, XRFSAT, DCSSAT, or REFSAT reflectors. This means using a common link command like “REFSATCL” to join in.
Please note that using a Hotspot that is setup for BOTH DMR and DSTAR will cause some issues, since it will grab onto the first active digital service. For example say you have linked into REFSATC and your hotspot is currently in the DSTAR mode. As soon as someone uses the DMR AMSAT Talkgroup, then your hotspot will switch over to DMR mode.
If all you plan on using is the AMSAT Talkgroup, then turn off the DMR Mode in your hotspot.
