 There is a Meshtatic to Nostr bridge that I want to look at which I think would be useful for the application of communicating information out of a crowd etc. I do wonder though if it would be fairly easy to jam the signal with interference in a small area as it is a very specific frequency.

I agree it is cool just as a neighbourhood or even city wide network if you can get enough users to build a mesh..

 I only know the very basics of EW, but LoRa is certainly harder to jam than any other civilian RF technology. Spread spectrum AND forward error correction!

 What do they use in military? I read that Russia has been doing a lot of experimenting in signals because of drones so really have no clue what is feasible today

 Its been more than a decade since I got out, and I was only really trained in how to recognise hostile EW and take countermeasures. Mostly just switch frequencies. I know the good stuff is all spread-spectrum chirps picked up by satellite, but unless you're in DSD they don't tell you much more than how to use it.

Basically the military uses LoRa-but-better, and with a bird in the loop for unlimited range. How much better is anyone's guess.

I've heard Russia way outstrips us in EW technology, but IDK any details.
