[CA] [CA11] ST60 repeater issue

[syfreedom]

Thanks for asking, it's the wind instrument. I was told at the local RM service that it understands, nmea0183. But I've learned recently that seatalk is much higher voltage (0-12v) than the pi serial output. Maybe I need to try another approach, putting the nmea to chartplotter, which again talks the information further to the repeater. The wind repeater needs the gps data also to enable true wind, so I guess this should be the way to go anyway.
