FEMA getting into broadcasting (apparently)

There is EMP but worse, there is HEMP (high Altitude Electromagnetic Pulse).

In 1980 at VTI we were treated to the story of the Starfish explosion, and while the pulse was bad, high ionization
and communication disruption continued for hours, and for a few frantic minutes the US military had no idea whether the ionization
would dissipate AT ALL.

Thank you again, D E Wiggins for some of the most informative educational moments of my life.
 
Did anyone else notice that the article on HEMP was posted on 4/20? Anybody else wonder what the real subject of that search was?

I wonder how well my little Honda eu2000i generators would survive an EMP....

Many pieces of solid state electronics would survive if not connected to anything that could act as an antenna (like AC power).
Of course, that's just theory. A real life situation could be far different. I hope we won't need to test the theory.
 
My simple mind thinks in terms of microvolts per meter and how my car antenna is somewhat close to a meter in length and 13,000 (insert emf here) per meter is somewhat realistic wherein it is also additive such that any wire becomes an inductor and becomes an add-on to the pulse.... ;D
 
God forbid we ever experience anything like that magnitude of EMP...but if it's true that old-school tube type stuff is pretty much immune, it explains why we've kept our old RCA BTA-5G transmitter (vintage 1955) as a working backup...
