As an adjunct to this thread. I noticed a strange thing today. The machine
with this noisy supply makes less noise, at least on the soundcard if you
take out the two ramsticks attached to its usb ports. This is particularly
noticable on the one plugged into the front port, presumably the wiring for
this is a lot longer.

So it sounds like the decoupling and conditioning of the supplies is even
more crap than at first thought by me!

Hi, you are indeed right, its one of those times when the fact that it
does what it says on the tin, is not enough. If I put a portable radio on
medium wave on a clear channel, when I switch the machine on, the same or
similar whining gurgling is heard. Other machines here have little
radiation at all.


Oh well, I have another one here somewhere!

Yeah I've heard that the Iranians jam BBC radio simply by powering up a
1000 low end Chinese PSU's.
