Im new to FTA, have recieved Pansat 2700a, manual somewhat brief. Ive been doing searches on LNBs and Quality. What is the Level meter next to the Quality meter ? What does Level mean or represent ? Ive seen level at 70% while quality at 60% , or , level at 99% while quality at 0%. Have located AMC4 with 1.2m dish at So. E. Alaska. Thanks
