Yes. Although NK is a bad example. Nobody likely has HF radios or computers.

But Russia, China, turkey, Afghanistan, Venezuela, absolutely.

My goal is to get adoption and have servers setup on different frequencies around the globe 24/7. The you just need a client computer. For now, you need windows or Linux or Mac(I think). It's a python app and a radio that has data capability.

As long as you meet those requirements, good to communicate on NOSTR.
