GB7NB runs Icom Hardware along with a PC running Centos OS with a ADSL connection to allow the internet connections. Software is G4KLX allowing connections to DPLUS, XREF and DCS reflectors.

You can connect on to D-STAR in two ways,  programme you radio memory’s with the different URCALL, MYCALL , RPT1 and RPT2 as I will describe below or use DTMF codes to access the different reflectors.  GB7NB can also be used as a stand alone D-STAR Repeater.

We have some downloads available specific to GB7NB / East Anglia for the Icom IC-E2820,  IC-92D. ID-51,Id-51 Anniversary  Id-31, Ic-7100, ID-5100  and the ID-880 , Which include all local Repeaters and simplex channels. Right click the relevant image and select “Save Link As”. You will need the relevant software to programme them and add you callsign etc.
ID-51 Anniversary,Id-51 and ID-31 software free from Icom here.

If you prefer we can programme your radio for you as long as you become a member of the repeater group.

Getting started
Register for Gateway access here.
The Radio needs your callsign and some other parameters installed first for D-STAR operation.
MCALL = is Your Callsign no spaces or slashes.
YOUR = Can be CQCQCQ or a Callsign you want to talk to

For my radio it would be set as per below :-

If you want to connect to a reflector for instance REF005A UK based DPLUS reflector you would change the CQCQCQ to REF005AL and press the PTT this will link the repeater to the chosen reflector. In the past we have set the memory channels to allow for all the UK speaking reflectors to be selected with a turn of the VFO but has you can see from this list which is just the D-PLUS reflectors the number of reflectors is quiet long.
So using DTMF allows you to have a single channel with YOUR field set to CQCQCQ and a simple DTMF key sequence to access the reflectors.

The s/w at GB7NB uses the format as follows for DTMF :-
DPLUS Reflectors *00101 or *1C  = Reflector 001 Module A
XREF #00101 = X Reflector 001 Module A
DCS Reflectors D00101 or D5B = DCS Reflector 001 Module A

The first part is the reflector number and last two characters are the module letter A=01 B=02 C=02 through to Z=26 as list of short codes can be found here.

Callsign routing / CCS
You can also register to have a 4 digit ccs code assigned to your callsign.
Register here and a list of 4 digits codes available here.
This is not much use if you are all using GB7NB as you will route to the same repeater, however if you are using a Hotspot , RPI Mega etc then you can route to each other using the 4 digit code and not tie up a refelector for local chat.
Not essential but good practice ensure you are unlinked from any reflector.
Key you microphone and send the the 4 digit code if you wanted to route to Mark G0LGJ you would enter 6942 the system will respond with Connected to G0LGJ and you can then talk as normal. To disconnect a CCS link press “A”

ID-51 / ID31  to send DTMF codes that you have programmed in.
Press MENU
Press DTMF/T-Call
Press Enter (D Pad middle button)
Press Enter (D Pad middle button)
Select DTMF you want to send
Press Enter (D Pad middle button)
Whilst Pressing PTT press squelch button as well and you DTMF will be sent.
