You can buy a converter from Raymarine. It's a couple
hunderd bucks. I've seen references to others but I don;t
have any specific references to them.

Hi,

I have a Raymarine ST 40 Bidata Log and depth and gather that I need
to convert the Seatalk output to feed the speed into a Furuno 1623
radar in NMEA format. Have seen a couple of threads, but has anyone
made/assemble/got a circuit to do the conversion???
