Perhaps we need to clarify and identify the 
relationship between the "Neutral" wire which
comes from the center of the 3-phase "Y" or
the center of the single-phase transformer which 
feeds most if not all houses and other small users, 
and the "Ground" wire that connects to that Neutral
wire either at the pole or at the service entrance.
The neutral wire is to carry the current that results
from uneven currents in the 2 hot wires, while the
"Ground" wire is to prevent someone from being
hurt if the neutral wire open up somewhere and 
makes what's left of it in the house hot.  Nothing 
has any interest in noise, radio or otherwise.
Look at this: A housetrailer neutral and ground
wires were bonded inside the trailer.  Only the
neutral wire came to the meter, and then to the
pole.  When that neutral wire opened, (bad splice),
everything on one side of the 220/110 feed was
placed in series with everyting on the other side
of the feed.  The refer on one side, when it came
on, blew heck out of the clock motor which was
on the other side.  Then, the refer had no power.
