I watched a great video on setting up a multi-mode Digital repeater.
It was a breakout session at the 2019 TAPR DCC conference. This sort of compliments the DMR Networks presentation given at the Nov 2019 YRARC Meeting. It also describes setting up a DMR XPR8300 repeater as connected to Brandmeister. But wait, this is not all. An MMDVM (hotspot technology on a RPi) board was used as a controller into a Motorola radio. Some of the concepts presented were similar to the IRLP/Echollink node the club has on VE3YRA.
