Subject: Grounding

I've heard a few things  about grounding and I was hoping to get some real
insight on this. Ok, the  secondary deserves a really good ground connection
but what about the power  supply and the tank circuit? Not to mention any
other line or transformer  circuits that might be included? Should all
grounds be independent? Should  they all be attached to the same ground rod?
How about multiple grounding  connections like water pipes and ground rods?
Should the ground connection  at the panel be used as well or separately from
the rest of the circuit? My  experience has been that the more the better,
tied together or  not.

Hi Tony, 
 
A common rule of thumb is to keep all the RF-carrying stuff grounded  in one 
place and all the 50/60 Hz-only stuff grounded separately. My method is  to 
ground everything from the control box back to the wall to the  (well-filtered) 
AC mains ground and everything forward of the control box to the  separate RF 
ground. If you Google the terms "ground loop" and "mains grounding  currents" 
you should get 250,000+ hits. While most talk about hum in low voltage  audio 
circuits, the same principle applies to the 10-20 KV in the Tesla primary  and 
the 200+ KV secondary, where you'll get much more than a "tingle" from a  
microphone, or a hum in your speakers. =:^O.
