The next task for the RTL2832 was  to decode aircraft transmitting A-DSB using Ubuntu. Doug G4DZU had previously pointed me at a link http://www.hamradioscience.com/the-rtl-2832u-sdr-and-ads-b/ with an idiots guide to doing it , so it was time to try

Installing gnuradio took one line (and patience):-

Catatan Antenna

with a piece of wire in the rtl283 antenna socket resulted in decodes from one aircraft almost overhead. Time for a better 1090MHz antenna. The J pole previously used was easy to build from 2 pieces of semi rigid cable so time to make another.It was tuned with a tracking generator/directional coupler/ spectrum analyser and achieved 32dB retun loss after tweaking. Putting this on the end of 35' of cable in the loft resulted in many more decodes and a torrent of data in the terminal:-
