my guess is something simple as a device that will either transformer or
opto  isolate  there are a few companies that make them   alot of devices 
used to connect rigs to computers have these built  in normally  at least
the good ones  so you don't have troubles

but i would quesiton  anyone who told you that info  below, unless they
actually came to your shack and tested it   otherwise  it could be a million
things  so that is why i suggested the test   did you have any luck trying
it??  what was the results??   if we can narrow do the common type of
problem maybe we can fix it
