I think I discovered something. Playing with audio levels on the computer, I think I have this background tone and pulsing coming from the com port down to acceptable levels.
I cranked the audio way up in Windows (was at a "2") and it seems to nearly completely mask this interference/feedback without distortion. I don't do much SSB, so it'll probably work out. If anyone else has ever experienced this when running their audio through a computer, I've love to hear from you ! Yes, I have the USB cable through a ferrite also.
