Im not sure if you’ve seen some of the newer boards out there but from the limited research i have done, this meshtastic thing seems like the future of grid down communication if enough people set up the infrastructure. It also helps that the frequency it transmits on is virtually impossible to narrow in on if you were concerned about lets say… radio direction finding.I have 3 meshtastics, here is a funny, I have been in it long enough to still have boards flashed with the old FW that does not allow the new app to work. lol I have used it for a few miles in Ms at the camp..
its slow, but it did send.
I will have a gateway node up eventually at the house to support internet link routing.
