Decibel Products 4 channel hybrid combiner

A Decibel Products 4 channel hybrid combiner is now used to combine all 4 of our UHF repeaters transmitters so only a single antenna is required!

This is a very expensive piece of equipment which we had to import from the USA.

It was well worth the expense as it works so well.

MMDVM GB7WB

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.
