    Slightly unrelated but a good place to plug my recent hobby. Meshtastic. set up a node and coordinate with friends to connect the whole area.

    Not only it is a secure clandestine chat network. it will work when the networks are down, allowing you to coordinate with everyone. Give them a battery/solar and they will work no matter what, electric grid down, you can still coordinate.

    I am currently working with local action groups to get the whole city connected

      Meshtastic uses AES-256, which is a symmetric encryption algorithm. I’d much prefer it if it could use some kind of asymmetric algorithm with perfect forward secrecy like what other encrypted messaging apps use.

      Its current implementation can lead to “store now decrypt later” attacks, and with the government probably having access to quantum computers, is not something I would feel comfortable with long term.

        Maybe I am overoptimistic, but I would love if hobbyist and action groups manage to get the whole nation connected. then you would not need a data plan or a carrier to be able to communicate.

            helltec v3 kits are about 20$ very few hobbies are this cheap to get in.

            Although I have gotten out of control I am keeping things cheap so far.

            Using some boom extensions that were about 30$ each and a couple of long range antennas for another 50$each and a few boards I am trying to test a connection between me and a friend.

            If it works well I will make a proposition in my DSA to connect the whole city as I am getting near the point where I can’t really afford to expand the grid by myself and continue with other action groups and mutual aid obligations I have.

            About connecting the whole nation, I am not sure if Meshtastic has a technical size limit, but without a doubt, if the grid gets popular enough that said limit is an issue, it will be updated or fixed.
