I'm glad I'm not the only one having a problem with LPBS. I tuned and tweaked and confirmed my alignment. I blamed the weather and the trees. It's now coming in but pixilating and disappearing . I've bit the bullet and ordered a 1.2m dish. SWMBO is mad at me for spending more money, and asking for her cable back. I'll keep you posted if I have a problem with the supplier.
