Go back and CAREFULLY read what I wrote about bonding everything together by

Done.  It's braid from each component (PC, PS, DK, radio) to the
copper bus bar on the back of the shelf and braid to the rod outside.

Not quite. Taking each piece of gear to that bus bar adds length, which adds both resistance and inductance. The ideal is point-to-point.
