[Elecraft] Mac Grounding

[Edward R. Cole]

None of my computer chassis are grounded directly to my radio 
grounds.  I made it especially that way to avoid audio ground 
loops.  All the computers are normal appliances with UL rated 
connections to AC mains which are required by code to have a safety 
ground tied to the main service entrance.  You do not see the 
millions of computer users worrying about having extra grounding on 
the computers.

IF your home has improper AC wiring then FIX that.  There is no need 
for extra grounding if your home is properly wired.  Lightning is 
something that no amount of grounding will prevent.  This has also 
been thoroughly discussed for those that want to know how to protect 
equipment from lightning.

More important is that the radio equipment have better grounding for 
RF as well as safety.  I do that thru a #8 awg wire to an outside 
ground rod.  Beyond saying that, the topic of grounding in the ham 
shack has been thoroughly discussed on this reflector (and should not 
need further discussion).

That's my two cents on this topic and all you will hear from me on it.
