[Elecraft] K2 grounding

[Paul]

It sounds like what is being said is not to ground the chassis of 
various rigs. That is, all modern rigs, power supplies, Home wiring 
already have a common three prong plug and that should put everything 
to a common "ground" just by plugging it in. This excludes such 
historical anomalies like the early Astron power supplies that didn't 
have the chassis grounded and are fixed by running a wire from their 
chassis to the DC negative post.

So the rod I have pounded in the ground outside the shack should be 
brought in the shack to connect to the antenna tuner only.  Do I have 
that right?

Because before I was running wire from the ground lugs of all the 
rigs, and computer chassis to a single copper pipe behind the gear 
and that pipe was then connected to the outside ground rod by another 
wire.

I think I'm mixing old and new technology. Maybe a lot of this 
grounding lore came from yesteryear when three wire power cables and 
gear design was not the norm.

If I wanted to check if I should attach some gear to that outside 
ground, would I put a meter between the outside ground wire and the 
rig chassis to see if I could measure anything. If so, what would I 
be looking for? Or put the meter between the chassis of two pieces of 
gear. If they all use three prong plugs, wouldn't they all be common?

Thank you and 73,
