2020 March dnd we are all locked down for the fight against Coronavirus please keep safe everyone !!

DMR is now the main digital mode and has taken new shape with hundreds of Talkgroups, all very confusing particularly when mobile,
there must be a better way to know what you are talking through on your favourite digital repeater ? and to limit the number of TG’s linked to what is one voice channel.

Bit of an idea with the recent announcement BM were finishing reflectors at the end of the year, sadly these had become unreliable and often disconnected from
the associated talkgroup and without solution. So I had a word with our good friend Jonathan Naylor G4KLX with an idea for his DMRGateway and new functionality for it.

As is often the case with Jonathan, within a few days he had come up with a first untested release and with a few more testing sessions on GB7IN small issues were resolved
and SUDO Talkgroup-reflectors arrived

These were just like our old friends the reflectors even the same commands for linking manual dial PC to connect to TG of choice, Status PC 5000 to see what the repeater is
linked with and PC 4000 to disconnect all with announcements to stop us needing to look at displays, however now you were infact with the help of the gateway using dynamic
Talkgroups but much enhanced. And a bonus we only need to remember 1 set of numbers as the SDO Talkgroup-reflectors use the same TG numbering remember we are really using the dynamic Tg functions
and providing the rest from the DMRGateway.

Give it a try just like reflectors manual dial the TG number, makes sure this is Private Call for example PC 2350 if linking you will hear the familiar annoucement that you are linked to 2350
you can now switch to TG 9 to talk over the TG 2350 traffic will return on TG 2350 but will required.


Please see latest XLX005 page for update the transcoding is now working after a short test phase thanks to those involved
with this special project


GB7IN back on air


We have been suffering some issues and GB7IN has been off air also GB3IN has limited modes DMR is working


Happy New Year to All I have updated some of the webpage content to reflect the current system at GB3IN and GB7IN.

Sorry the webpages are often behind the features provided due to lack of time


Not to much to report about the repeaters.

I have recently been busy consolidating our datacentre services providing infrustructure for the UK D-Star DCS005 as well YSF reflectors and Brandmeister DMR UK Master servers

The services are now hosted in a datacentre near London.

The system consists of our own dedicated server which runs a virtual host environment and individual virtual machines run the different services we provide. Things have grown over time and often the server is supporting upto 500 connections to repeaters gateways or hotspots.


We are currently testing some new software at GB7IN which allows us to be multi-homed onto different DMR networks (currently 2) You have all the standard features you know on Brandmeister our primary network which all work in exactly the same manner.

We also now have access experimentally to the DMR+ Pheonix network via TG8 on Slot 2 Reflectors on DMR+ can be selected by prefixing the reflector by an 8 ….so if you wanted 4400 you would simply dial 84400 this is a trial with thanks to those on Pheonix UK (note this is not network bridgeing and both networks remain seperate the repeater has the ability to join both networks.

In order for this experiment to work for users of both networks, we are also carrying TG 235 slot 1 and TG 844 slot 2 East Midlands, however this is not the recommended method of access for our own users and is aimed at users only familiar with TG operation.

We would always encourage access through the DMR+ Pheonix reflectors that are on TG 8 slot 2



Finally the D-Star returns to GB3IN

So we now have D-Star and Yaesu C4FM Dual mode on GB3IN

Today I have configured the long awaited (I am told) D-Star this includes of course full networking to all systems ircddb routing and CCS7 and all the features we have grown to expect on GB3IN, remembering the G4KLX  D-Star repeater started here something we are very proud to be a small part of.


Still some work to do to improve the RF performance of the Yaesu DR-1X this needs to wait till warmer weather !!

73, Jon G4TSN


Currently I am working on getting the D-Star returned to GB3IN, we bought a so called plug and play solution from NW digital, so it should just work famous last words !!

I hope to complete this in the next few weeks.

Also the Yaesu repeater RF performance is poor to say the least currently, we have always had commercial spec. equipment, although old this has always worked very well in an environment with multiple transmitters close by not so for this Yaesu so far. Watch this space.


The refurbishment is going well

GB7IN  is now installed and is working well, actually it has surpassed all expectations, proving the  G4KLX  MMDVM HB repeater to be much better for Amateur radio  than any commercial DMR offerings,at a fraction of the price, without compromise of performance.

Thanks of course to our good friend Jonathan G4KLX once again for his dedication to this work for the good of Amateur radio, and we are really very proud it all started here at GB3IN

Careful choice of radios is a key factor with MMDVM and we have gone with the TAIT 8100 series which, really are suited to this purpose.

GB3IN is coming on well and shortly hope to complete the upgrade returning D-Star to compliment the Yaesu C4FM




After several years service we have recently started an extensive upgrade to the hardware and services provided by the repeater.

After much thought we have decided to go completely digital.

This has started with Yaesu System Fusion C4FM but with a link to the YSF reflectors, rather than Wires X Network.

I firmly believe this is offering the best structured network connectivity currently for Yaesu C4FM.

May we take this opportunity in thanking Lee Marsh of ‘LAMCO’ Lam Communications Ltd Please Note NEW ADDRESS  5. Doncaster Road, Barnsley, South Yorkshire, S70 1TH. For the Donation to the Team of a Yaesu DR-1XE Dual Band Digital Repeater, Good Luck at your new address. 02/12/2016

Shortly this will be joined by D-Star on 2m with all the usual linking facilities that comes with D-Star Dplus DCS XRF and IRCDDB

So the aim is for Yaesu C4FM and D-star on GB3IN as dual mode

We have applied for a UHF repeater GB7IN which will be  on the same site as the VHF repeater once licensed this should compliment GB7RR repeater and other DMR repeaters on the Brandmeister UK network.
