Just 'rediscovering' Squawbox now that the Port 30003 data is live. You are right tarbat, much more usable with RadarBox now :-)
I wonder if it would be possible to modify to have a filter by Hex code group? I'm more interested in what the mil aircraft are squawking, rather than trapping the mil aircraft by squawk code group. I'll drop Andy a line and see what he says.
