[Elecraft] Radio Shack ESD mat doesn't meet spec

[Don Cunningham]

David,
I was the one that brought this mat up (unfortunately), and all I can say is 
that it was fine for putting my K3 together very successfully and I'll use 
it again.  I'll stop there, but will add that any time I like, after walking 
across my floor here, I can draw a spark from metal objects.  While building 
my kit, I followed Don's suggestions to the letter, always putting on the 
wrist strap before beginning and touching the mat before any parts or tools 
and grounded the "system" through the mains ground in my shack (tied to 
shack ground too, of course).
As always, one should weigh evidence and do what they see as the solution.
73, and I'll go back into my cave,
Don, WB5HAK
