MAINSGROUND----------SHACK-----------RFGROUND BAD

I may still be confused here, not really fuly comprehending the above illustration.

The mainsground comes to the shack anyway in the AC outlets powering the shack,
being the third or ground terminal (although not really connecting to my Kenwood
530 which in this unique case only has a two prong AC plug and internal power
suppy.

I think this ground thing has to do with the "routing" as you indicate, just as the
mystery of ground loops in an old tube hi-fi amp where the correct star grounding
is the way to get rid of hum. As long as my shack RF ground is a short direct route
to the first ground rod of the series, I should be ok then tying the mains ground
to a "later" point in the RF ground rod system. (?)
