Not needing to rely on infrastructure beyond what you deploy is a pretty sweet way to take a degree of sovereignty over your comms. And yea, while not common, you can sejd Bitcoin over radio -- though I imagine Cashu would be a lot easier and more practical. LF has Nostr set off on radio as well with his Hamstr project.

This is super cool thank you for sharing! I've been wanting to learn more about ham radio and it's interesting that my interest in solar storms might come in handy to that pursuit! 🥰
