Watching the WB Transponder you'll need the capability of DVB-S2 and very low symbol rates. If it's old, it can't do DVB-S2 (and probably only down to 2000KS/s).
I decided to use a Minitiouner Pro V2 with the F6ZZP software.
Have a brief look here: https://wiki.batc.org.uk/MiniTiouner_hardware_Version_2
To watch TV you'll need drivers (where to get ?!) and a DVB application like the technisat program, progdvb or similar.
Perhaps somebody know the exact Model of your card. Then it's easier to find the right software+driver package.
May be this one:
I found a german installation manual, see page 10. The photo looks similar to yours.
A hint if you install drivers: please do clone your windows harddisk. I had some bad experience in my past during a crash of the software. i could reinstall windows many times. Since then I use an imager for my hard drive.
Best regards, Mike
I’m using one of these under win7 for monitoring the signal from various satellites with SatFinder software. https://www.fastsatfinder.com/
As said Mike the card isn’t for DVB-S2 standard but I can see many DVB channel as well to listen to satellite radio…
