Hi Dave (K1WHS),
I have a bit of an description on how I removed most of my RFI from the
shack located at:
https://www.nk7z.net/category/info/rfi-mitigation/constructing-a-shack-for-minimal-rfi-from-the-ground-up/
Scroll to "Rebuilding the Shack from scratch".
The link above is a link to a set of articles on removing RFI from your
environment, so you may find other articles of interest.
Don't forget to check out K9YC's very informative and useful articles at:
http://k9yc.com/publish.htm
Look under "Ham Radio Topics", there is more information than you can
absorb in a day at his site, and all of it is good.
73s and thanks,
Dave

I have been rebuilding my little hamshack these last few days. I am only
operating on one band (160M) so there is not much gear involved, but I
am trying to do it all correctly to minimize noise pickup from common
mode signals arriving in the shack from many RG-6 beverage feed lines.
Most of my work is outdoors preventing common mode noise from
propagating along the RG-6 coax. To help things along inside the shack,
I have installed a large copper buss bar with numerous attachment points
for wide braid connections to all the AC powered equipment on the
operating bench plus anything else that has RF or audio involved. I
have bonded everything to this buss bar and have routed a couple of #8
ground wires in conduit from the buss down to two ground rods situated
below the shack. I have a separate ground rod about 25 ft away for
grounding the beverage feed lines. I noted that several shack items
had no provision for grounding. One of them was the P3 panadaptor.
There is no ground on it. The inside is pretty empty so there is plenty
of room to install a ground lug. My question is will a lug modification
bother some new accessory/option that Wayne 'n Eric have planned for the
empty space? Maybe an Elecraft Sno-Cone dispenser or Elecraft coffee
maker? The logical spot for a lug is on the back panel. Am I safe there?
Is it good practice to bond the P3 chassis to ground? It gets 12 VDC
power from an external source, and it seems logical to have a separate
ground point and not count on coax cable shields for any ground
connection. I had a DX Engineering NCC-1 with no ground as well as the
computer, recording device, an Astron power supply etc. They are now
all bonded to the copper buss bar.
