The 1.8m dish connects to a ProfTuners 7301, that loops out into an Airspy SDR running SDR Sharp tuned to the IF frequency and virtual audio cable allows the recovered audio to be used in Jaero. As luck had it the list of requirements that John posted perfectly matched everything attached to the PC under my bench so it was a five minute job to get it running. The interest here of course is positioning data for air enthusiasts, I guess you'd liken it to a global ADS-B set up. This system has been put in place since MH370 highlighted the poor coverage of flights on trans oceanic flights, much of the early work was focussed on L-Band as it's relatively simple to attach a GPS or patch antenna to a suitable receiver but now Jonti has updated the software to decode the 10500 bd burst signals being relayed by Inmarsat from planes. I was only made aware of it by a John Locker who helps develop Planeplotter software. Jonti is probably the only source of hard information at the moment with some observations from the handful of us decoding these signals.
