I wonder how you count the aircrafts seen : When I have begun to feed data in september 2013, I was using a dongle and a small antenna on my roof, never seing more than 100 A/C simultaneously.
Now that I have a 1090Puck and a dedicated antenna on a pylone, I see around 150 A/C all day long and my A/C count in FlightAware is lower that in the “dongle period”.
So I wonder how you count the aircrafts seen per day : different ones or lost and recovered ones ? Number of “segments” ?
I mean that some stations with a very limited sight have an impressive A/C count and I find this quite strange.
