Prog Finder alwas have 55%


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.... Foxy
