I recently saw a comment chain about nuclear bombs, and that led me to thinking about this. Say there is a nuclear explosion in the downtown of my US city. I survive relatively fine, but obviously the main part of the city has been destroyed, while major zones extending from the center were also badly damaged. What would be a good response to (a) survive and (b) help out the recovery effort?
Tip regarding radio: 2182kHz SSB near the coast. That frequency is monitored by authorities globally. It’s the MF equivalent of maritime VHF ch16.
Technically, the same goes for 2187.5kHz, but that’s for digital transmission only, and unless you have the required hardware to encode/decode it, you won’t be able to make sense of it.
Source: I have a GOC
CB radio has really short range and there’s little likelihood that authorities would be monitoring it.
2182 kHz is long range marine radio and only good if you’re on a boat. I don’t know that anyone you talk to would care about a person on land while they’re handling their own maritime emergencies.
If someone really wants emergency radio I’d suggest ham radio or GMRS.
