> Plus, say a nuclear weapon went off anyways and all the FM transmitters died. Is anyone seriously thinking a lone AM transmitter 2000 miles away is going to help?
AM radio is simple enough to build with makeshift materials (https://en.wikipedia.org/wiki/Foxhole_radio). You don't need batteries or even a power source at all! (the radio waves themselves can bring power)
If civilization had a catastrophic event, I would guess that AM radios would be one of the few surviving technologies
I would love to see kids given the materials and taught how to build makeshift emergency radios in science class every couple of years. Then they could take them home, stick them in a closet or drawer somewhere, and in case of emergency, they would be everywhere.
Now that is thoughtful, and I think, can open the conversation to youth what if, and of what to do in case of... I know as a kid we had Civil Defense, and that funny little CD symbol on the AM dial...
