I've been running it at home in one spot, so maybe something is there.... I'll check GND coupling, and since I'll be shipping it out from work, I'll give it a test there just to see if the noise is still the same.
Amazon's prices fluctuate quite a bit, and right now repurchasing it would cost me quit a bit more. So it work properly I'd be very happy.
And if you do get the chance to check one you have, I would like to know the result.
Thanks again,
Dave
