With effect from approx., 1:30 pm on Saturday 30th April 2022, GB3JB became fully operational. A day earlier than planned.
It remains on 2m, but now using the TDMA DMR Tier II system, and as part of the existing South West Cluster of 9, 70cm repeaters.
The guidance quality image opposite shows the combined coverage’s of the 10 repeater systems, which is available via Slot 2, on any of the Cluster repeaters.
The SWC of DMR repeaters began to form in the earliest days of DMRs appearance in the UK. It has slowly but steadily grown into possibly the largest UK regional cluster of linked repeaters; 10 systems.
All the repeaters in the cluster are independently of each other, with their own management structure and are funded by their own Group, Club or by donations.
The SWC is not connected to any other DMR network, such as Brandmeister or Phoenix, etc., and there is no direct internet access via a hot spot, for example.
TDMA DMR is not compatible with D-star or Fusion systems, which are also not compatible with each other, either.
Obviously, at a site with a relatively easy unauthorised public access, safety and security is a priority.
We therefore try to do our bit. A couple of examples are shown opposite.
We have signs warning not to climb the tower. Even though we have installed anti-climbing panels, idiots will always be idiots.
We have also provided warnings as to the use of 24 hour CCTV facilities on the site, which cover both the internal areas of the locked and secure barn and the external areas outside of the barn.
If you are not directly associated with the servicing and maintenance of GB3JB and it’s associated equipment and facilities, or directly associated with the farming of the land itself, you enter this privately owned site, totally at your own risk.
There is no public right of way across the site, and no unauthorised public access at any time.
