GPS input to DSC VHF radio

[Bilgediver]

I It is normal to send AIS date at a baud rate of 34800. However the XM radio is only listening for GPS data which is usually sent at a slower speed. You will have to set up both sender and receiver at the same baud rate ie 4800. This rate might be a bit slow for other equipment listening for AIS data.

No need to program it.

Would it be possible to feed a Ublox with 5volts and get an NMEA 0183 signal for direct input to a DSC radio? (My Garmin GPS 120 seems to have stopped feeding position to the Simrad RD68. No obvious loose wires and several failed attempts to make them interface.)

I don't know your radio nor am I technical. However I would think that if you go down the U blox avenue you are likely to get stuck unless you fully appreciate post 40. U blox was cheap and I think my friend enjoyed the challenge. Getting a second hand Garmin GPS would probably be a lot easier. Unless the problem lies with your radio.

I fitted a Polstar PGM-248 to feed NMEA 0183 to my Simrad RD68. Simple fix and GPS + Bukh converter + connectors were less than £15.

4.8Kb won't handle very many AIS messages at all, so data will be lost.
