Afrikaans Comms IS going to be ABSOLUTELY essential, you folks need as many HAM/ CB and PMR users as you can get. NOTE most VERY IMPORTANT you need as many of them as possible but NOT licenced because if they are licenced the government knows where all you comms are located, you need to be monitoring 24/7 and have decent radios spread everywhere plus a messenger system of people who will relay messages around the community.
Your BASE stations must be capable of being moved to prevent seizure and triangulation, If they kill your lines of communication they effectively cripple your community.
