I honestly don't know what the rules are for this ham in the Netherlands, but if I was to implement his design here in the US, I'd put the nodes on a commercial band frequency to avoid the encryption mess under Part 97 rules. For #EMCOMM I've been toying with the idea of using one of our town's dedicated public safety frequencies for a UHF band LoRA #reticulum #RNode network. #hamradio is too restrictive with the required individual licensing and rules regarding encryption, etc. For example, in a #disaster we can hand out radios from our town's radio cache to non-technical volunteers who otherwise meet volunteer requirements (background check, etc.), and not worry about a ham license.
