I've read that OpenCPN is expecting DSC messages to be imbedded in the AIS stream. I have a DSC class D radio. It has a DSC nmea output. I would like OpenCPN to pick up these and DSC messages and plot them.
So, my question is; Can I use the DSC nmea output from my VHFradio to plot DSC buddies on OpenCPN on my laptop if I don't have AIS?
Not sure what you mean by "pick up these and DSC". If you have a DSC radio but not AIS and you have an MMSI programmed into the radio then yes, you can plot your buddies as long as they are sending you position reports.
I have seen this work with the latest version of OpenCPN when connected through an NMEA multiplexer outputting at 38,400 speed. I don't know if OpenCPN will recognize DSC sentences at 4,800. I suspect not.
Thanks. The VHF spec. does not say what the baud rate of the nmea out is. The input rate is 4800 so, I guessing output is also 4800. I think I'm going to plum it up and see what happens. I appreciate your help and I'll let you know what happens.
