If it were me, it would be a Bluetooth or WiFi wireless interface
along with all the other instruments. It's time marine electronics
joined the 21st Century and dumped serial ports.....dammit.

so why not crack open the 802 brain and install an opto-isolator
inside? one could get a twinax connector with a BNC body that
oughta fit into the same hole that's there and then the NMEA-0183
link could float like it is supposed to do.

No, no, Scotty! I said, "Beam me a wrench.", not a WENCH!

Trust me - if you think NMEA 0183 running unbalanced is truly flakey,
be *very* careful what you wish for in the wireless arena.
both bluetooth and wifi are *not* the stuff of life-critical apps.
if i'm counting on the radio's DSC to tell someone where to
come save my life, i want a WIRE connecting it to the GPS unit.
I agree completely that the interface on the 802 *should* be
done right, but one can also put the opto isolator in a tiny
metal box with a panel-mount BNC Male so that it just goes on
the back and then the 0183 runs isolated as per design. There
are nice balun enclosures made which would be splendid for
the job.
again, I agree completely that it shouldn't be broken,
but it is, so the question becomes
"What's the easiest way to make it better since establishing
blame is both trivial and pointless?"
