A place for people who like to be prepared for realistic disasters both human created and naturally occurring!
We expect there to be thematic overlaps with outdoor, survival, general preparedness, self-sufficient living and resilience... also gear talk is welcomed wholeheartedly.

It's definitely a cool option for complete off-grid comms. There is the option to use MQTT as well for messaging, but that requires internet to work. I'm planning for no internet, so that's what I 'train' with. You can make it so you are on the 'open' channel for anyone to jump into, directly contact individual nodes, and/or make 'channels' that only other people with the same encryption key can access for group chats. No subscriptions or anything else, plus there are a ton of different hardware types available, antennas, and other options. And overall, fairly inexpensive to get started.
The only real 'difficult' part is if you live near a mountain range. Without other nodes from other people around the peaks or setting up repeater nodes yourself, getting past mountain ranges isn't going to happen.
