Have a Viewsat Ultra behind the BSC621-2 and I have to set the LNB High to 10600 to pick up KU sats.I was having a heck of a time getting AMC-9 tuned in.Its my south sat and I thought I had a major problem someplace until I switched over to 10600 on the high side. I always thought that you set a universal LNB at 10750 for KU. Anyone else that uses the 621-2 have to set the LNB High to 10600?
