A lot of Spain has just lost satellite coverage, however my neighbour with a 180cm dish is working fine and my setup with 135cm dish is working almost OK. I am getting a usable picture on most channels especially at night. Why would nightfall make a difference? And during the day everything seems good with a clear sky except BBC1 and BBC2 which pixelate. Searching this forum I found this: Is what is being said correct? I am getting Strength = 85%, Quality = 50% on the channels I have checked. I think I understand that Quality is a measure of how much error correction the receiver is doing, which corresponds to how clean the signal is. So what is Strength? Is it what the person said above? Also, from other posts it seems that I may have scope for improving the Quality and my end-user picture by adjusting alignment of dish, skew of LNB or a better LNB - without having to upgrade the dish. Does this sound reasonable?
