I thought the whole idea with these SDR "Dongles" is that you could
decode practically anything in software. Unless the required bandwidth
is too high, and perhaps not in real time, but they can be decoded. For
example, people do SSB and FM with them, neither of which are anywhere
close to DVB-T modulation.
Couldn't something like that be done with HamTV?

Raydel,
Apart from the frequency and signal level differences, DVB-T is a 6-8MHz
wide signal with COFDM modulation, using 2k to 8k subcarriers, while DVB-S
is a single carrier, 6..36MHz wide signal, usually QPSK or 8PSK. You cannot
use a downconverter and a DVB-T receiver to tune into a DVB-S channel.
However, the digital bitstream carried by both is the same - so if you have
software analyzers and audio/video players for DVB-T they will work for
DVB-S too.

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
