Yeah, a old tube FM-receiver is a good thing to have. I bought one but its not working, yet.

Mine too, problem is in powering them after an EMP.
That's why I bought two R-392's and I'm looking for a T-195 transmitter to go with it. I love my R-390A's, but they won't be much use without a good 120v power supply.
There are diesel-generators that you can start with a wrench, they have no electronics. I saw one second-hand a week ago. They are considered EMP-safe.

What are you going to do when you run out of diesel?
Solar panels charging a few batteries? All of the ham gear I have will also run on 12volts direct and my Zenith T.O.'s can run on internal batteries.
Solar panels are sensitive to EMP maybe? In a nightmare-scenario the sky will be so dark that the sun is blocked perhaps, God forbid.

The panels probably aren't, but the controllers absolutely are.

All solid state radios will have to be shielded, as well as the controllers for the panels.
Which is why we were discussing tube radios, but there again you have to have a way to power them. Inverters work, but are also solid state.
Hence my comment.
Yeas, I understand. All this equipment can be stored in a metall casing so chanses are they survive EMP. But I dont know, maybe solar panels is the way to go. I have some solar panels.

Maybe, but always keep a mind of the second EMP after the first one.
If I was a person who was gonna nuke EMP someone, I'd do another one not long after just to make sure.
Tube radios are not immune to EMP. The vacuum tubes themselves might be but vacuum tube radio equipment can and has been damaged by high altitude nuclear EMP, especially if it's powered up during the EMP. In the Russian tests in 1962 over Kazakhstan, nearly all the radios used vacuum tubes. In 1962, other than small consumer transistor radios, the only solid state components in common use were selenium rectifiers in radio power supplies and the Soviets did not have the technology to make them. Tube radios were knocked out over a 600 km radius, and a (tube) radar installation was knocked out 1000 km away.

No one said they're immune, just far more resilient.
The electric grid is the worst and all things will probably be fryed if connected. Also waterpipes will get charged, long conductors pick up a lot of electromagnetic energy.
? I am not sure what you mean?
