Wow!! Heavy Rain with ThunderStorm now and even the QPSK tp's on Bell 82W went down but still the C-Band signal , The Word, on 91W is working perfectly. It just cut the audio very rarely during the heaviest part of the storm. I managed to tweak the lnb better and now signal Q is around 40% but still this is the one and only C-Band signal I can get with this 90 cm motorised dish. I guess FEC 1/2 helps a lot. After the rain I will try with another 90 cm Dish (non flimsy like this Fortec Star which also has minor bumps from a previous Storm) to lock to the Univision signal on the same bird.
BTW , during mid night , the signal started to pixeleate and became unwatchable at some point around 3 am, and Q went down from 25 yesterday to barely 4. No idea why since the weather was the same or slightly better. Maybe the sat drifted away at night time and gets closer to the center of box during the day although I do not think this is a daily process , it takes several days for the sat to drift away. Usually Center of Box days are that , days during the month (reported with specific hours) and not hours within a day, every day.
So far I am very happy with this Gospell C/Ku LNBF although to be fair this is my first C band LNBF so I have no reference to compare with others.
