[R-390] R3XX GFCI Issues

The real REALITY in our shacks is that we MAY HAVE NO CHOICE but to run 
a separate circuit for OUR R-3XXs!

We ALL know that the filters installed leak JUST enough to trip a GFCI 
protected circuit.  So wholesale changing the filtering is NOT the 
proper method of "FIXING".  IF the filter is up to spec, leave it in 
place to do ITS JOB.  Take a HEALTHY look at shack circuits.  Put one in 
place that is NOT GFCI protected OR use an isolation transformer 
methodology!

AND for Lord's sake, INSTALL A VERY GOOD and HEALTHY ground system with 
EVERYTHING grounded!

I have four, (4), copperweld rods outside the shack, all connected with 
1/4" bare hard copper clamped AND soldered to the rods.  This has been 
brought into the shack in ONE CONTINUOUS RUN that is attached to a 2" x 
12" x 1/4" copper bar.  All equipment in the shack it tied to the bar 
with a MINIMUM of #10 AWG.

DO IT RIGHT!  If you don't. YOU may be the next SK!
