Hi Tom, Each ground wire has different losses, and picks up different noise, so in fact, while they are the same on a gross level, on a fine level, they are different. The closer together they're tied, the more they'll be the same. If the intent is to minimize differences, get them very close together. If the intent is to isolate noise from the other, the further away the interconnection point is, the better.
We used to install isolated ground systems for HP computers back in the old days, since they were very sensitive to noise coming in the power line. 73, doug Date: Thu, 11 Aug 2005 08:01:00 -0400 From: "tom.w3qs" <[EMAIL PROTECTED]> Thread-index: AcWeDCu0x19GI2pERq+NLxNnUJYg5QAXmtUw Hi Stuart, I have heard this so many times I think it has become 'general knowledge', but I don't get it. Say you have two power strips plugged into the same wall outlet. Surely the ground leads of both are then physically connected inside that wall outlet. Aren't the ground leads of both then physically connected? For that matter, all grounding leads are ultimately connected to the same physical terminal on the house's power panel. Again, I know there is 'conventional wisdom' that talks of 'two' 120 loops in a 240 house, but still the ground leads are all connected - at least they are at my house. What am I missing?

IF the computer is NOT used with radio, have it separated or on different power circuit.
