There can be two paths to ground. One from the back of your equipment to

ground in the outlet back to breaker box to house ground then back to
station ground. That creates a large loop depending on how much AC
wiring involved.
Mark,
I strongly suggest that you study N0AX's ARRL book and/or my tutorial.
What you are recommending is WRONG and UNSAFE. It is also illegal.
Ward's book is excellent, probably costs $30-$50. My tutorial is free,
covers the same material and recommends the same practices. We
collaborated on his book. http://k9yc.com/GroundingAndAudio.pdf
I use several of those three prong to two prong AC adapters to break
the path in the AC ground leaving just one path to ground through
station ground.
Again, that is unsafe and illegal.
All chassis grounds are connected to AC ground so
electrical safety isn't compromised. Really cleaned up a lot of noise
with my station.
If it solved a problem for you, your station has other bad
grounding/bonding practices.
