DMR Coverage for South Wales

GB7CW & GB7SA connecting the Valleys to the World 

About the dmr south wales group

Linking South Wales to the World….

In 2015 Tom (2W0TRR), Gareth (2W0GME), Andrew (GW0UZK), and Karl (MW0HUY) wanted to add an additional repeater to South wales to cover the areas previously not covered at the time. OFCOM wouldn’t allow an additional FM repeater at the time so it was decided to add a DMR repeater which at the time was a new digital mode to Amateur Radio. This is when GB7CW and DMR South Wales repeater group was created. During 2019 we took on an additional repeater in the Swansea/Llanelli Area named GB7SA.
