TD, there was thread on this a while back...
I believe the radio in question is the Standard Horizon GX2100-series
which, unfortunately, is not available in Oz. It has an AIS target display showing MMSI, Call Sign, Ship Name, BRG, DST, SOG and COG and allows the user to quickly contact an AIS-targeted ship using DSC which is kinda cool - especially in an emergency.
The GX2100 provides NMEA output to a chartplotter, which it needs to get GPS data from (NMEA again) since it doesn't have a built-in GPS - so it's really intended to be used with a chartplotter and an associated instrument suite... although it seems there is now a GX2200 with inbuilt GPS!
Do keep in mind that these radios (this one anyway) are AIS receivers
- not transponders. That would require something a whole lot more sophisticated again, with an associated drain on the batteries.
