[HomeBrew] comuter speakers

[R. Blackman]

Thanks to all who responded re: RFI in my speakers.
I will  HOMEBREW these suggestions ( you see, this was on topic after all)
and report back. It is not the soundcard / line to the speakers. They call
CQ DX
even when not attached to the computer. I will attack the power supply next.
Item of interest:  I bought some new speakers from the dollar store for
4.95$
hooked them up and the problem is 95 % gone! But now I get a huge hum /
ground loop
perhaps when splitting off a line to the radio for BPSK / SSTV / RTTY
drive.
The beat goes on.....
