[Milsurplus] Question about EMP

[jcoward5452 at aol.com]

If it comes to NEMP I think the issue will be moot for those of us in 
an urban setting,however the days of Mutually Assured Destruction are 
over in my humble opinion.If there were a nuclear exchange, I beleve 
the US would come through with minimal loss and the adversary would 
cease to exist.We still maintain a formidable arsenal and no-one else 
comes close.
  A 55 gal. drum with a good lid can hold a lot of smaller radio 
sets,probably a complete GRC-9 with gas generator.Better yet sink a 
concrete septic tank and seal up the input ant output holes and voila a 
storage bunker.You could even water seal the concrete box before 
putting in the ground.

Some MIL radios and other electronics are protected and some aren't. It 
mostly depends on where they're intended to be used. If a radio's not 
designed 
to survive EMP, there's not a lot you can do to provide proper 
protection 
short of enclosing it in a grounded metal box that forms a good Faraday 
cage. 
But the antenna will still be a vulnerability path. 
 
What kind of EMP do you want to protect against? There are two kinds: 
LEMP - Lightning Electromagnetic Pulse 
NEMP - Nuclear Electromagnetic Pulse 
 
LEMP isn't really a problem if the radio's at least a kilometer from 
the lightning event. 
NEMP can be a problem even if the nuclear event is 1/2 way around the 
world. 
 
I spent a lot of my Lockheed EE career designing EMP protection into 
airplanes and 
associated electronics. I'll be happy to help you if you can provide 
more detailed info 
on what gear you want to protect and from what kind of EMP. I'm afraid 
the NEMP 
won't be piublicly available, though.

Are the modern military radios destroyed by EMP or are they protected? 
I am 
not refering to the ionization of the air, but the melting of the 
germanium 
in solid state components. 
 
If they are destroyed how can they be hardened or protected to prevent 
this? 
Is there any kits for this? Are they available?
