hi.just completed my first full afternoon of tracking with rb.there is something inherently exiting about watching things unfold in realtime.my location in s.oxon means i am getting quite a cosmopolitan cross section of flights from different airports. i will probably look to extend my range,and therefore my track time with an external antenna,as there are a lot of obstuctions near my house,not least the Chilterns.thx guys for all your posts much appreciated,and happy tracking in 2009!
