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

Subject: [amsat-bb] Question about HamTV

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,

Raydel
