Jim,

Just keep in mind when  you do the work, the quality of the house ground to 
earth is far less important than having everything entering the house being 
bonded to act like one common point.

One of the biggest mistakes in amateur radio grounding over the decades has 
been having the shack antenna and control cable entrance ground 
non-existent, and the common shack desk equipment ground to an independent 
ground.

The shack ground must be bonded to the mains ground so everything entering 
the house is as close to one potential as you can get it.

Correcting things may not cure your RFI, but it always makes things much 
safer and more reliable.
