33 packets with no antenna

[Paul_Sengupta]

I've currently got one of my Pi B+ PAWs acting as a ground station. In order to not be flooded with transponder traffic and just concentrate on the P3i stuff, I've unplugged the antenna from the dongle, with the PAW just sitting in my living room, though not that far from the window.

Today I received 33 tranponder packets...
