if your receiver misses channel when you scan, this means that your dish is not pointed the best it can be. Furthermore, the fact that you need 1.2 to find better signal and not using USALS is more evidence that you need to get out and adjust your dish.
?nd remember that these satellites dont have hundreds of channels. They only have a few. Look to lyngsat to see if your missing something.

SPDIF cable output in the back.
