SDR Radio using GQRX to a C Band LNBF to pick up S-Span on AMC 11 131 west

C Span is the last analog TV channel on satellite in North America and I wanted to see if I could get the audio picked up with my $20 SDR usb dogal Radio.
At first I was confused on where I should have the LNB lo set to. If I entered 5150
I think I need it set to zero and go by the L band frequency’s
I went by this chart!

and went by https://www.lyngsat.com/AMC-11.html

3840 V NTSC

If anyone knows anything about old satellite audio please let me know.

Wanted to play around with C Span as it is the last analog channel and will be going away soon.

See my video on how I had my setup
