Yep, first thing out the gate. You need a DMR radio and not a D-Star radio.
Once you have a radio, you will need to get on the DMR-MARC site and apply for an ID.
Once you have an ID you will need to program your radio with that ID and the TG is question along with the repeater and time slot information for your region (local repeater) that is on the DMR-MARC system.
