La réception d'image télévision DATV
The same receiving line will be used to receive digital television images transmitted on the second QO-100 transponder, the 8MHz wideband transponder.
To do this, you must switch the reception polarization of your LNB to horizontal. For this purpose, you will supply the LNB with between 15 and 20 Volts, in accordance with the LNB’s characteristic sheet.
In place of the SDR reception equipment and the SDR Console software, I recommend the implementation of the DATV receiver board designed by the French OMs F6DZP, F1TE : The Minitiouner Pro and its Minitiouner software.
I do not develop this subject in this article at this time. But for now, I invite you to find all the useful information about DATV on these websites.
