I would be surprised if the 803 was not already coated. Conformal coating
is a non-conducting waterproof coating for printed circuit boards that is
formulated to not effect electrical properties. Usually a silicone or
urethane. It is applied after the board is assembled to protect the solder
joints and components from harsh environments. Several compainies make an
after market conformal coating spray that is easy to apply. Tech Spray,
Chemtronics, MGChemical and CAIG are a few trade names. The down side is
that it makes board level repairs a real PITA as you have to strip the
coating before doing any testing or repair. There are some strippers but
they have to be used with care as they can disolve the whole board if you
are not carefull.

Glenn,
What is "Caig conformal coating?". I think I may need some for my new
MARINE
ICOM 802. I'd like to get the Icom designer out on a rough night in Bass
Strait. We had better waterproof connectors on automotive electronics
10years ago.
