I'm guessing if a solar flare takes out communication infrastructure then CB radios will still work.
Not that. It creates atmospheric conditions where certain bands can bounce off the ionosphere and transmit beyond the horizon. Hams can get pretty damn far around the whole globe.
Edit: I was checking on the details of how far hams can go, and Google's AI slopped this out:
No, bad LLM! Moonbounce and Ionosphere bounce are distinct things.
Hum, why would CB radios still work? It would fry any kind of equipment with wires. In 19th century when that big flare event happened the telegraph lines caught fire. Anything with a filament inside would fry.
Not filliments, conductors. Such as the ones running through through your home
You can build a basic radio manually with a little bit of know how. If you have spare capacitors, they're likely to survive and be pretty replaceable. You can rig up an antenna out of any wire, it just needs to be the correct length and it'll work to some degree.
If your entire house goes up in flames at once, well, spare parts are probably not on the table
That makes sense, I thought it would make the signals clearer or something.
