I have everything set up the same on the SV8000 as I do in my nFusion HD and my Junxbox, all the correct symbol rate and FEC (21500 and 3/4a), but on both 91 and 82, I can't get the "upper half" of the transponders - anything above TP #12 or sometimes #16. Shows good signal, but no quality. Nothing I can change fixes it. It seems like it's failing to switch into the upper half of the frequency band. nFusion and Junxbox still work fine on the same dish/cable. Has anyone else seen this and any idea how to fix it?
