VHF and GPS COMMUNICATION
Just when we thought all the dealer installments (read ‘screw-ups’)
had been fixed….
We found yet another one…
Our VHF radio has never communicated with our GPS,
meaning that before activating the DSC
we would have to enter our coordinates manually
and every 4 hours thereafter,
should there be an emergency.
Now whenever something doesn’t work we automatically think:
“OK what did they screw up this time?
Sure enough this is sadly becoming all too predictable
…a super hornet’s nest of wires and not just poor connections,
but wrong connections.
Below deck access…
From the CPS Boat and Engine Maintenance course
we learned the troubleshooting methodology:
first check the obvious,
then check the easy,
make no erratic adjustments.
We hoped it was the wiring and the ‘obvious’ assumption was that this was another screw-up.
I remember insisting that whatever VHF radio the dealer installed,
that it would be able to communicate with our Raymarine GPS.
…so Francois hauled out both manuals,
then redrew the schematics.
