Hi Russ.

There are numerous sources of interference that can be generated from a
computer.  A good place to start is to turn the monitor off and see if the
noise goes away.  Some monitors generate a lot of noise.  Sometimes
changing the video signal cable can make a big difference.  I experienced
that with a NEC monitor that I used to have.  You can try using ferrite
cores on the cables coming out of the computer, although I've had rather
dubious results.

I also had a computer that had a rather noisy SCSI controller, and a leaky
SCSI cable.  Changing the SCSI cable went a long way towards reducing the
noise output.

I have found that sometimes the switching supply in the computer can
generate a lot of crud also.  If this is happening, there isn't much you
can do about it short of replacing the supply with a better one.  The
bottom line is, this probably won't be easy to knock out.


Quiet computers are hard to find.  I usually hang on to them with a death
grip when I find one.  I cannot get this one that I am typing on anywhere
near a radio or television because it has one of those noisy switching
supplies.
