Brandmeister DMR on GB7IT

GB7IT is our DMR repeater which is connected to the Brandmeister network.

We are using a Yaesu DR-1X repeater with an MMDVM KI6ZUM board and TCXO on an Arduino Due plugged into the rear 15w HD connector of the DR-1X.
The MMDVM is run by a tiny Raspberry Pi 3 computer with the KB5RAB image installed.

You can now operate through GB7IT on 439.5125 MHz with a -9 MHz TX shift using DMR.
You listen on 439.5125MHz
You transmit on 430.5125MHz

On DMR use timeslot 2, talkgroup 9 and colour-code 1 to talk to the World via the brandmeister network.
The local chat channel is on TimeSlot 1, TalkGroup 235145, colour-code 1.
