Thanks for sharing that very interesting link, Tom!
It's awesome that we can listen to a 10 GHz downlink like that, and see so many simultaneous conversations on the waterfall, and listen just by clicking on the one we want. I heard several French and German QSOs in progress. There was also what may sounded to me like an Italian QSO too. At this moment there are 7 SSB QSOs, and several digital QSOs in progress.
The VHF (144-146 MHz) SDR at Goonhilly is available too, by clicking on the base station photo at the upper right corner of the QO-100 SDR web page. We can hear the mode-B downlinks there too, when they are in range of the omni antenna.
