[Boatanchors] News story about risk of high altitude EMP

[WA5CAB--- via Boatanchors]

That was an asinine thing to write.  Vacuum tube gear IS more resistant in 
general to EMP than is solid state.  And generally discrete circuits are 
more resistant than IC ones.  That part of the equation has absolutely nothing 
to do with the power grid.  An EMP would likely take out any HT made in the 
past 40 odd years, but not, for whatever good it would do anyone, sets like 
the BC-611 or AN/PRC-10.
