[R-390] Ham Shack Grounding Help!!!!

[Jim Temple]

A couple of years ago I installed a computer in my shack.  When the computer
was on it wiped out the radio frequencies.  I tried all the recommended
fixes and spent a lot of time wrapping cords in ferrite, etc.  This helped a
LITTLE, but I simply got around the problem by running the computer as
little as possible.

THEN ONE DAY, a lightning surge damaged the computer.  The shop replaced the
computer power supply and the problem completely went away.

It appeared that the computer power supply was the problem all along.  I
would try to replace the power supply with a new one.  They are not very
expensive and might solve the problem with little effort.
