i'd love to see some grassroots-powered clandestine para-web running at least partially on radio. obviously such a project would either immediately or at some point face the usual issues like: spam, cp etc. that's why i believe such a network would have to be slow. it would have to be so slow (and just fast enough) for text-based communication and simple protocols. and i mean text as in < 1kB ... not sufficient for transmitting sth like base64(videoclip). that would be so cool.
I always wanted to do something like this with "earth mode" radio. That is, signals sent through the ground. You can put a couple conductors in the ground spaced far apart and send signals into them and it can be picked up miles away apparently. Would be really slow, so probably text only, but also probably no one would notice. I also vaguely wonder if this would still be regulated by the FCC since it's not through the air...
Reticulum qualifies as that. It’s designed to run over LoRA. (The radio protocol, not the LLM thing.)
Check out the DigiPi and all it can do.
Internet via Ham Radio aka Packet Radio is a thing: https://themodernham.com/ip-over-ham-radio-via-new-packet-ra...
Pair it with the Gemini protocol and you're there: https://en.wikipedia.org/wiki/Gemini_(protocol)
