Use a dedicated ground power outlet for your computer.

Unless you have a 1-radio "station" and no lightning protection of any
kind,
this is a very bad choice.

The dedicated power outlet for the COMPUTER is wired by the electrician so
that
both ground leads (white and green) are wired directly to the breaker panel.
The power and ground is NOT
looped to other outlets. It is a dedicated power (and ground) outlet for
computer use only.
It is typically an orange colored power outlet.

This was not intended for radio use. It is simply suggested to keep radio
equipment powered
on a separate power circuit from the computer with the computer ground going
directly to the breaker panel ground.
That IS the single point ground for the house power wiring - at the breaker
panel.
