Hate to bring an old thread back to life, but I did not want to post a new topic on such a long shot.
I am currently sharing my ADS-B data with a few sites such as planefinder.net . Recently I noticed someone else in the Austin,TX area has set up a station to the east side of Austin, or so I assume. They seem to be able to track most flights arriving and departing KAUS and even them just sitting on the ground at the airport. I think this is awesome, since my receiver/antenna do not reach the airport, just to about 1500 above. If you are out there speak up! Would like to hear more from you. Thanks.
