I have a 70cm Raven Gemini dish with 3 LNBs on (my setup can be seen HERE). In the mornings when it's sunny the signal level on some channels drops low enough that we completely lose the signal on those channels.
As the sun moves round later in the day the problem disappears so the key factor appears to be the location of the sun. At the time when we lose the signals the sun is in the south-east directly above where the dish is pointing. If clouds come across and cover the sun then the signal comes back again. When the clouds move away again exposing the sun the signal gets lost again. If there is no clouds in the sky at all then we won't be able to get a signal until at least mid-day when the sun has moved far enough round to the south, away from the azimuth of the dish.
This doesn't happen on all channels, just some of them. On those channels the signal strength is usually ~70% when we're receiving a good signal but when the sun is above the dish this drops below 50% thus causing the signal to be lost completely.
Is this a "known" problem when the sun is above the dish (is do, why does it happen?) and is there anything I could do to try and prevent this happening so we can watch those channels reliably on sunny mornings?
Thanks.

so I'm not sure about the channels coming in on the other single output LBN pointed at 19.2E as we don't regularly watch anything on that one to be honest. The quad output LNB at 28.2E is also used to feed our Sky+ box and we NEVER have any loss of picture on with any channel on that no matter what the time of day is or if the sun is in/out. The strange thing is that it is only 2 of the Russian channels on 13.0E that completely lose their signals while the others remain fine (although still with a lower percentage quality, just not enough for the signal to be lost).
