What bothers me about the M802 is its openness. The case is open.
The cooling fan is INSIDE pulling the boat's salt-soaked, humid air
into the case where ALL the boards, those cheap little white
connectors they use on the antenna tuner and control cable connection
are all over the boards INSIDE the case. Nothing is sealed, nada.

I was working on a 96 ft yacht, some weeks ago. I was also wondering about
this. Many units from expensive equipment were open: power supply units from
the Sailor VHF's and even the black boxes from all (3) satellite systems.

OTOH, I recently received one of my multiplexers back after a year of
cruising: no oxidation whatsoever. And these are also open to salt air.
