I been doing some more playing with DMR using my TYT MD-380 UHF handheld. Since I first started playing with this, there is now a second network operating locally,
http://dmr-marc.net/ the original DMR network here in VK
and the other network
https://brandmeister.network/ or referred to as DMR-BM,
which is very interesting as it comprises of homebrew repeater equipment, such as the MMDVM repeater which is based on Arduino a kit and interface board, which does more than simply DMR, they also doing C4FM and planning on P25 support. Also DV4mini doing Dstar, C4FM and DMR
Just in the Sydney basin, we now have VK2RCG 439.500 (Sydney city), VK2RWW 438.100 Dural, VK2RLE 438.425 Heathcote, VK2RHP 439.750 (Horsley Park), VK2RAG Central Coast and one planned up Newcastle.
And of course the DMR repeaters in pretty much all states now, including Canberra VK1RBM.
What this means is since they share Talk Groups, you can be travelling around Sydney and switch repeaters and maintain the same Talk Group QSO. You don't have to chat via a public Talk Group, you can setup a private QSO with another person.
In summary, a whole different concept compared to the old fashioned FM analogue repeater, it takes a bit of thinking to get used to the idea, but once you understand the concepts, then you soon realise the benefits of it. As it grows, you will see a lot of multi-mode digital repeaters and gateways appearing.
