Grounding A Radio ?

This would help implement the "single point ground philosophy"
that everyone says is the way to go.
If I do, can I then rely solely on the coax shield being the receivers
ground ? This would be from the radio chassis to the ground bar, of course.
Then there's the question of the AC power plug's center pin grounding the
chassis.
There goes my single point system, I guess.
Should I perhaps inhibit this pin with one of those cheater-plugs ?
I'm also wondering about any safety implications if I do disconnect the
chassis to water pipe
ground wire I previously installed, AND also use a cheater-plug so the
chassis isn't directly
connected to the AC ground at the plug. Not sure if just relying on the
coax
shield back to the ground bar is safe ? Thoughts ?
Also, my house 220 V input does not seem to have any ground rod
outside, like I believe the new code requires. It does seem to have an
interior wire
running to my house's water line. I seem to remember from years back when
the service box was opened that this wire was from the neutral bus, but not
100% sure.
I would not really want to change or disrupt this present house grounding
scheme by bringing this wire 125 feet or so to the new ground rod I will be
installing.
Any thoughts or suggestions on what would be the best grounding
configuration for
the radio (from a noise, safety, and possibility of any induced lightning
surges) ?
Thanks,
Bob
