Hi Allocator,
Have already since few years a dual channel AIS receiver, the SR162
and even (not in use at the moment) the SR161.
If the software isn't too expensive I consider to buy it, without network.
Can use Shipplotter on my main pc for viewng other areas worldwide.
My Shipplotter/DSCDecoder/Maritiem Comms program PC(as also mySR162 + RB)
is in the loft, just use it via UltraVNC on my main PC.
Agree ShipTrax program looks nice!
