I think the assumption is a radio inside a faraday cage, imagine say a box made of copper, no RF can penetrate so the radio would survive a distant nuclear explosion.
A close one would blow everything apart so you don't want to be there🙂
@sonhouse saidOh, I know what a faraday cage is, my question is: why a short wave radio, instead of a long wave radio...

ok, when the term long wave is used that is in the US the band below the AM broadcast band. Not much going on there, some broadcasts in Europe but I don't think there are any here, about 100Khz to 500 Khz. Now AM radio, here 550Khz to 1710 Khz does have a lot of broadcasters, So a good antenna can pick up those broadcasts from a thousand Km away and more.
But short wave, which starts at say 1800Khz to 30 Mhz, there are broadcasters and here most of what passes for short wave broadcasts are survivalists and if there was a nuclear war, they might still run and broadcast emergency information and the antenna for those frequencies say around 5 to 10 Mhz, the antenna's can be a lot shorter than a dipole for 1 Mhz.
there are antennas called Loop antennas which are small, maybe a meter loop or smaller that can really give a boost to AM radio wavelength, High Q which means you tune it for best reception at a particular frequency and gives gain over the internal antenna of a regular AM portable radios.
So it would depend on just how many nukes how many stations would have power, some would have emergency generators which could power a station for some time depending on how much fuel is available and there are a lot more AM stations than short wave but short wave stations can reach out a lot further away than AM stations.
Local CB (Citizens band) radios are more numerous than AM but much shorter range so local folks could keep in touch since you would not need much power for those units, say ten watts to run it which can be had with small solar cells.
Then there are hams, running between 1.8 Mhz and UHF frequencies and they usually have some kind of emergency power for just such emergencies including some solar systems and hams have a much wider frequency ranges than CB radios.
CB radios run around 27 Mhz, and if the nukes went off during a solar maximum, that band would have a very long range but at solar minimum, ten or 20 Km is all you can expect out of the typical 5 watt transmitter.
Hams can have a thousand watts and more legally so Hams would be the ones to disseminate emergency information which we are trained to do in emergencies. I myself was involved with emergency communications on 9-11 in Brooklyn but that was strictly local.
In a nuclear attack hams would transmit a LOT further so links would ensue all over the planet.
But a regular radio listener would of course not have access to the sophisticated transceivers hams use so they would be limited to picking up random stations as best they can and the wider frequency range short wave radios would have a much better chance at finding SOME kind of emergency transmissions and they may not even be able to understand ham calls because hams use 'single sideband' modulation which is incompatible with regular AM and shorwave radios so it would take radio's like my Tecsun 880 which can tune in single sideband transmissions from hams. Of course there are AM ham broadcasters too and most hams can broadcast in AM so there should be information available for most any radio with a decent antenna, AM or shortwave.

My God. How complicated.
Well, the chances of a nuclear war are very small (the people who decide wars don't have much urgency to destroy the wealth they enjoy).
And if there is an all-out nuclear war, listening to some crackerjack mumble on about his AK47 won't be high on anyone's list of priorities.
Party on.
@shavixmir saidhttps://www.arrl.org/files/file/Technology/pdf/119962.pdf
You keep a short wave radio in a farrady cage, in case of a nuclear war?
Why not a long wave radio, so you have a higher chance of picking up signals?
I’m not actually sure about how radios work…
@shavixmir saidSo WW3 will not lead to a nuclear war? Is that why Bill Gates has underground bunkers in every home he owns?
Thanks for the explanation!

Biden already tried to start WW3. He failed, but what makes you think he will not try again? Are you fooled by this slow escalation? Are you ignoring the cluster bombs my government is giving Ukraine so they can attack Russia?
Zelensky kept lying by blaming Russia for the missile Ukraine shot into Poland. Biden's intelligence officials lied to the AP and they had to retract the false claim. Biden did not hold them accountable for trying to start WW3 with a false flag attack by Ukraine. Biden obviously approved.
@Metal-Brain saidNobody is starting WW3.

Well, not a WW3 in any sense other than a proxy sense.
And no, a world war will nog lead to a nuclear war.

A nuclear war will destroy most of the planet and currency, as we know it now, will be meaningless.
The people who define policies and earn from the system, do not want all their rewards destroyed. That is why a nuclear war won’t happen.
@shavixmir saidThen why are they building more nukes?

That whole MAD assertion is complete BS. The entire southern hemisphere would be spared from most of the chaos.
I suggest you lesson your reliance on rumor to form your opinions.
@Metal-Brain saidBecause they make the money that makes people rich and is why they won’t be used, because then the wealth that they’ve created will be pointless.

You should read Closing Time, the follow-up to Catch-22.
Where they’re selling the concept of a plane that can withstand nuclear blasts and can take out surviving operation centres and deep built bunkers.
“It doesn’t have any wheels after take-off.”
It doesn’t need wheels, if you have to use it, there won’t be anywhere to land anyways.
“It doesn’t have any wings.”
It doesn’t need wings, if you have to use it, it’s failed as a deterrent and is pointless to fly.
“It doesn’t have any bombs…”
And that’s basically the concept behind all deterrents like nuclear weapons.
If you have to use them, it’s too late. And if you use them, everything you wanted them for in the first place is gone.
They make money. And that is it.

"Because they make the money that makes people rich "
That is a conspiracy theory.
And nukes are not the only EMP. There are non nuke EMP bombs and natural CME caused EMP.
You really are a clueless dolt. Only nukes? Really?
