The mix 31 I placed on the AC line at the input of the converter was
common mode. But as noted in my initial post, it had no effect
whatsoever. Nor did an isobar power strip with its filtering components.
It's all about which cables make the best antennas, and at what
frequencies, and with what directivity to our intentional antennas, in
any given installation.
Another generality is that commercial filters don't do much to kill
noise BECAUSE most noise is common mode, usually on the "Green Wire" due
to poor construction of the noise source, and the Green Wire bypasses
the filter. There are, of course,exceptions.
