No problem. Rage 61 and 62 are (probably) 2 x F15 aircraft out of Lakenheath. Because they are manoeuvring and/or flying in and out of cover of my antenna, there are being picked up for a few minutes then are lost, before being picked up again. Hence the multiple records in the Report. RadarBox sees these as new flights due to the time lapse between detection times.
I can't really see a way around this, other than having some sort of time filter. JSTARS has a manual time setting to try to prevent this. It's just a slider control so you can set it for example - if an aircraft appears multiple times in a 10 minute period, then only count it once. It's crude, but it reduces the problem to a degree.
I don't think that this is necessarily a Beta V3.05 problem, it's the fault of the aircraft flying in and out of cover! I'm not sure that a software change is really needed?
