Hi Raydel,
I stand to be corrected but a these dongles are specified for DVB-T so I dont think they would work for signals using DVB-S modulation.
The signals from the ISS will be at 1.3Msps or 2.0Msps - I believe that only the Technotrend T1600 and T3200 cards have, so far, been identified as being suitable for these very low symbol rates http://www.technotrend.eu/2920/TT-budget__S2-1600.html
It is anticipated that more detailed info for potential ground stations will be made available quite soon.
thanks

Hello,
About the future HamTV experiment, is it possible to use a cheap RTL DVB-T dongles used or RTLSDR to receive such signals with proper LNA and downconverter. If the downconversion fits the signal on a proper channel does it device is capable of decode the transmitted format???
Thanks,
