In the UK, we have access to a two major networks:
Brandmeister and Phoenix-UK (which is linked with DMR-MARC, DMR Plus and the Northern DMR Cluster), which offer local, regional, national and international connectivity.
Then there is the SALOP Cluster and South West Cluster – each contain several repeaters that are linked.
It’s important to know that there is no link between all these networks/clusters despite them using similar talk groups and/or reflector numbers and names.
As at late June 2018, Phoenix UK and Brandmeister UK created a link between the networks. Phoenix TG2353 is linked to BM TG2353 (Ref 4403) which is UA on both networks.
At the end of January 2019, GB7SK (Phoenix) added TG23590 which is linked to Brandmeister TG23590 (East Midlands).
Regardless of the network/cluster, TG9 is local – it does not go through the network/cluster and is much the same as using an analogue repeater.
Here’s a map to the various networks – DMR UK Repeater Map
The maps will not always be up to date as they are snap shots taken of a live map which is updated on a regular basis. Should you wish to check the repeaters on the various networks, please refer to http://www.dmr-uk.net/index.php/uk-dmr-map/
