Hi Jim--
I think that language you quote was more a product of Icom legal than Icom
technical and is designed to cover old houses as well as more modern ones.
If you have a three pronged house mains system which is itself properly
grounded, about all an additional equipment ground will do is perhaps get
stray rf into your system or provide a path for lightning surge damage to
your equipment.
And since a large % of 706's are used mobile, I'm trying to visualize how my
car is going to maintain "a long earth-sunk copper rod" going 60MPH?? ;-)
Not making fun of you but I do think the Icom manual oversimplifies the
issue a bit.
