Hello,
I am attending Dayton this year and it is good that I will not miss out
on learning more about SDR. I plan on bringing a good portion of my
listening shack, including my USRP, to monitor Radio Communications in
the area. 
My hotel is around 12 miles from Dayton International so
maybe I can pickup some 1090 MHz transmissions. The fun will be waking
up early to attend the sessions.
