Is it still illegal in Europe to buy radios with 128 bit encryption?
You do need authorization to buy a transmitter though, at least where I live.
Weird it's regulated, given you can use mobile phones like that (sure, you need coverage).
Yes, it is also illegal to post PHI over pagers, due to HIPAA addendum in 2016.
But 1986 ECPA law forbids decoding pager messages unless they were intended for you.
