I seem to randomly see planes on the ground at the local international Airport. They come up 20 -30 or so at a time , then lose signal right away. What would boost the signal then take it away?
turning transponders off and on?
unless it’s some kind of ballet, they wouldn’t all come on at once.
My guess is the signals are being reflected by something.
If it only lasts a couple of seconds, it’s likely to be reflections from an airborne aircraft.
That’s kind of what I was thinking but I wasn’t sure if that was possible.
right, or on a pretty busy airport… but i assume there is none these days
In Amateur Radio circles, there is a subset of talent that communicate beyond LOS by bouncing signals off airborne aircraft
