Are we re-inventing the wheel here? I understand in the USA there is a
broadcast radio warning service for emergencies run by the NOAA. I believe
the radio receivers sleep in stand-by until and alert, and there is a way to
limit the warnings to quite limited local areas.

Perhaps one of the US linkers has some experience?
