What is the FreeDMR Network?
It is made up of Independent Servers running the FreeDMR Server Software.
They have OpenBridged “OPB” to each other to make up the FreeDMR Network.
Neither Master nor Slave :-
All FreeDMR systems are equal, just like all of the individuals who run them. Each server is free to run as this wish.
FreeDMR is developed by hams for hams. Much of the work has come from the UK and European ham fraternity. They have worked on many of the old bugs that commercial systems would never fix to meet amateur radio requirements.
