Kim Jong say - EMP fry all you Yankee Ipads! HAHAHA

Perhaps us old heads who love tube gear ain't as dumb as we look...






"Put simply, EMP destroys electronics. There are actually four phases of an EMP pulse or four separate pulses. Each affects different types of electronics. Of these, the fourth one is the most dangerous, as it interacts with the earth’s electromagnetic flux, causing a huge energy spike in the electrical lines.

What Will Be Destroyed & What Will Survive?
The question of what will be destroyed in an EMP is one that receives considerable attention. The most common thinking is that everything electronic will be destroyed. That includes, the electrical grid, cars, airplanes (both use computers extensively), all forms of communications, and anything else you can think of, that uses electricity. However, old tube-type radios will survive.

There are two basic ways in which electronics will be destroyed by an EMP. The first is by direct electromechanical radiation. This will enter electronic devices, frying the delicate circuitry. As electronics have become more computerized and more miniaturized, they have actually become more susceptible to this sort of EMP damage.

However, some electronic devices, like cell phones, are small enough that they may not absorb enough EMP radiation to destroy them. On the other hand, desktop computers and entertainment centers have a network of copper cables attached to them. Those cables will act as antennas, attracting and absorbing the EMP and channeling it into the delicate electronics, where it will destroy them.

The second major way that EMP will destroy electronics is through a very rapid and massive electrical surge in our power lines. This will be big enough and fast enough that normal surge protectors will be useless. It will hit everything that’s connected to power lines, destroying delicate electronic devices."

1. "Perhaps us old heads who love tube gear ain't as dumb as we look... "

One might say the same about we who like the outdoors and do well in it without electronics, as well.

2. "Naked and Afraid"


Was the real thing.

28 days with virtually nothing, not 3 or at the most 5 days like Bear.

Bushcraft is just as important.

That I agree with.

4. If you go with nothing, you're either on reality teevee or you're fence post dumb.

Theres a whole lot of room between "with virtually nothing" and "no electronics", too.

3. When I went through Air Force ground radio school the R-390 rx

Was one of my blocks. It was all mechanical and tubes.




When I got to my duty station the first HF and UHF radios I worked on were mechanical too.

10. Oh lord...

nearly 60 years later and I still remember when a tube on our old TV would die and my dad would be behind that dinosaur trying to replace it.

Cursing the whole time

Who knew that the old dinosaurs could someday make a comeback in a post-EMP world
