Hi all,
One additional comment regarding grounding for RF interference,
extraneous noise & elecrical safety considerations is that the preferred
method for grounding should be:
Single point grounding, ie all rig & amplifier ground connections
should be taken from a single point, (shack grounding buss).
Relying on "daisy chain" grounding for example: through coax
cable(s) & their connectors; Rig > Amp > tuner > tground point can be
the source of intermittent RFI & distortion
problems that can be difficult to nail. This approach to grounding
should NOT be used for the foregoing stated reasons.

Excellent advice. And there are other good reasons.
Here's a talk I did this fall at Pacificon on the topic of grounding
and bonding.
