Irregular range lines in flight viewer map


I noticed in some people’s screenshots instead of circles for range it has a more irregular shape, I presume that is to show where there are the most flights, and gives an idea of coverage. How do I enable this? I have a Flightfeeder. (Orange one)


There are several programs that can do it: Virtual Radar Server, modesmixer, adsbscope and so on. Just Google their names.


Oh I figured this was a stock feature. I’ll have to look into those programs.
