Hi
I have a vu+ duo, with a 80-85cm dish (unsure exact size), London area.
I am experiencing some weak transponders on 28.2, channels such as BBC news with a SNR oscillating between 23-28. Strangely enough, if I give the dish a little nudge using Fine positioner movement (East by a couple of short nudges), situation gets a bit better. On the other hand, quite a few 28.2E channels have a decentish SNR of 40-45.
Asta 19e is fine for example, with SNR above 70%. 13e is also very fine.
2 questions:
1) Is it normal for 28.2E to have a much weaker SNR than ASTEa 19e? What should be a good SNR on a well aligned dish for 28.2E weakish transponders on a vu+ duo? 80cm dish/ bogue standard LNB/South East area.
2) I have a strong feeling my dish has probably been installed sligthly misaligned (hence the two nudges helping a bit), but how can I make my dish remember the right position for this specific satellite, as I use USALS?
