DVBS2 and a symbol rate of 30000, yep you got to be locked on solid or experience stuttering at times it seems.Even though I have the 10 footer "tuned up" better and am getting S90 and Q72 I still have an "odd" problem with the NBC channels. This is on 105 "C" band. The quality does not dip or drop, it holds steady. But I get freezing. It can be a few seconds or just a very quick pause. With such a signal and quality, I wonder what is the problem?
