[Elecraft] grounding K3/KPA500

[Don Wilhelm]

Grounding to the AC receptacle "round" connector will normally suffice 
for AC mains and safety ground.
As for RF ground, you may get away without it depending on your antenna 
situation.  If you have "RF in the shack" problems, "counterpoise" wires 
may be the best solution.  A quarter wave wire for each band you intend 
to operate will provide a low impedance (RF Ground) for that band.  The 
wires can run around corners with gentle bends, but be aware that they 
should be insulated, especially at the ends because they can have high 
RF voltages even at QRP levels.  Treat those wires the same as an 
antenna element with insulators at the ends and keep the wires away from 
possible contact by humans and pets.  Insulated wire is OK.

An artificial ground will do the same as the "counterpoise" wires, but 
must be tuned for each band.  Your physical situation will dictate which 
alternative you should choose.
