I have a Raytheon RC630 plotters. Can anyone tell me what sort of antenna I should use? I currently have an autohelm dGPS antenna on my wheelhouse roof but this doesn't seem to work even though the plug is the same?
No other gps source either!You don't know whether the dGPS antenna works. I think on the RC630 that if you plug a GPS antenna into the GPS socket on the display, you need to select "Navaid" priority rather than NMEA.
Do you have another GPS source? If so, connect it to the RC630 using the NMEA input and see what happens.
