How can I found out if I have Signal? If I connect it with a receiver and my TV, it worked 100%, but not with my SkyStar 2 USB

Yes, ProgDVB shows the same values...

Hallo, I want to use my Technisat DVB-S USB2 Skystar 2 on a Truck (mobile) but evertime I start Proc Finder to search for Astra 19.2, the Programm show me always that I have Level 55 and Quality 20%. The numbers don´t change, if I turn the dish. Can anyone help me, what I do wrong? Thx for help.... ...
