My God Wayne, you're quick. I just posted this.

Thank you very much for the advice. $200 is $200 and I can use it
elsewhere. I shall install chokes as per your suggestion.

I am really looking forward to email at sea. I have had it previously
with an Iridium phone that my department head hired for me so that I
could continue to manage my project whilst crossing the Atlantic. As
they had paid for it, I did not feel comfortable in emailing friends
on non-government business.

cheers

I have a Pactor III on my boat and we did nothing special for
grounding beyond what was already there for the SSB. If your existing
SSB is working OK I would not worry about it.

What *is* important is to use lots of ferrite RF chokes on all of the
inputs and outputs to the Pactor and to the laptop computer. This
will help to prevent stray RF energy from getting into the digital
circuitry and causing problems.
