[Elecraft] Grounding Mat Chatter

[Nick-WA5BDU]

This thread got me off onto a tangent, trying to measure resistances on 
some of these anti-static materials, such as the black foam pad and the 
silvery "plastic" envelope.  I had a capacitor discharge through the 
unknown and used a MOSFET to monitor the capacitor, since a 10 M-ohm DMM 
would have discharged it.

I got 33 G-ohms between two electrodes about an inch apart in one of the 
black pads and 4.2 G-ohms between two electrodes 1/4 inch apart in one 
of those envelopes.
