Jim,
This is a most interesting thread...
A quick question: Is it best to connect equipment together from chassis
to chassis, or from each individual chassis to a single point ground? I
was taught it's best to connect each to a single point ground point,
e.g. to a copper buss bar behind a shelf. And, should it be a short fat
copper wire, or short wide copper strap? The latter is certainly better
for an RF ground.

Sounds to me like the best plan is to run heavy gauge wires between
the power supply and radio, which is what most setups do. This

When you do the math, you learn that it's not as easy as that. Yes,
short fat copper for that path is a good thing, but what's more
important is short fat copper from chassis to chassis of all the
interconnected radio equipment, and any accessories having an
unbalanced connection to that equipment.
