I recently modified my Superdish 121 to point to 119/118 using CB2008 (replaced 119/121 LNB with it)
Now, I get variable ranged signals on those two satellites, mostly good. But some TPs have either no signal or very low quality signal. For example, CNN TP sometimes get 30-35 range quality and sometimes 0. I noticed that Signal shows 99 when quality is 0? Tried to move around the dish & LNB combination and can't get it better. All the TPs having more than 50% quality always stays like that and I get those channels good.
FYI - Have good qualities on 110 LNB which I haven't touched. I have Pansat 3500SD
