MB6SG is a simplex digital voice gateway with D-Star and DMR capabilities.
It is owned and run by G0KUX.
The gateway system consists of a Raspberry Pi 2 Model B / MMDVM board running the Pi-Star system.
It is located in Southgate, North London on 144.825 MHz using a Motorola GM340 running 5 Watts ERP using a 5/8 over 5/8 collinear vertical antenna around 9 Metres AGL.

Please Note:
MB6SG defaults to the D-Star Reflector, REF001C at start-up and after 15 minutes of inactivity.

DMR
The gateway has DMR capability on the DMR+ / Phoenix system.
 
To use a Talk Group, select it on your radio and press the PTT briefly.
This will activate the Talk Group on MB6SG.
Settings for your DMR radio are as follows:

Frequency Tx and Rx: 144.825 MHz
Colour Code 5

A document I found very helpful in explaining DMR.
Dummies Guide to DMR

To use the Digital Voice network you need to register for your DV ID.
For DMR registration:

For D-Star registration:
https://www.pistar.uk/new_dstar.php

I would strongly advise that if you are new to digital voice that you go for D-Star.
D-Star radios are far easier to set up and use than DMR radios.

CODE PLUGS
I have made a basic code plug for use with MB6SG for the Baofeng RD-5R (Tier 2 / Dual Timeslot version) / Baofeng DM-9HX and Alunce HD1 radios.
I can make a code plug for your radio if you inform me the make and model of your DMR radio and where to obtain the programming software for your radio (for licensed radio amateurs only).
To request a code plug email me on the link below.
