Ah, that would do it! Thanks Donald.

Henning, are you just using your GP1090 to receive AIS plots? Do you have a secondary antenna plugged into the the other SMA plug on the receiver?

Because you can purchase any decent Airband antenna to not only listen to ATC through the SBS3, but the same antenna will give you much better input signals for ACARS decoding and ship plots, all in one. Much better than a 1090mhz tuned antenna.

The SBS-3 comes with a throw out aerial for the AIS and ATC signals and I am using that one to receive the AIS plots. I know that I could buy a better one but to be honest I don't really need it. I can receive the plots of the ships that I can see outside my window and that's enough for me. I'm more interested in the planes :-)
And the throw out aerial isn't that bad anyway. Yesterday I received plots from a ship about 25NM away until it disappeared behind the horizon.

As the AriNav System polar plot is restricted to 300nm, my son wrote a Google based App where you can select the range you want. When I entend the
range out to 700nm, my polar plot looks like this. There is a definite straight line across the northeast, where the Brisbane-Auckland flights are being
tracked.



Also interesting was the number of transmissions received since I setup the AirNav Systems RadarBox in March this year. My RadarBox has received
1,144,729,694 (1.1 Billion) transmissions, that's an average of 64 per second over this period. I have seen peaks of around 450 transmissions per second.
