From reading pdfs here and there, I know there are FAA ground stations that listen on 1090 Mhz and send the data the FAA data centers.
So the local airport can get a heads up while planes are still out of range of the 1090 antennas at the airport..
What I'm doing here, is listening to the local planes around the greater Boston area, and sending the data back to PlaneFinder
so they can display the data on their website.

I have a nice 1090 antenna installed. (On loan from PlaneFinder).
My dongle is doing a pretty good job, but I hope to have more professional equipment soon..
Wow, it's way after my bedtime..

PS:
Just got the shipping info, the 'professional equipment' is on it's way.
Hope to have it running in a few days.
I see you are from north of Dallas, I'll bet you have a ton of air traffic around there!
