HD channels missing on 1west

OK, clear.

Is the skew of the LNB correct (i.e. zero for a motorised dish, knowing that this will not be perfect on the 3 Astra's)?

Ah right ok.... I'm not at home at the minute but from what I can remember the lnb is slightly twisted to the left or right. Il try that then placing it dead central to the dish and whilst it's already positioned at 0.8w

And from what ur saying there , obviously it is normal that the signal will reduce at the likes of 28.e, 13e etc by doing that. The signal is currently in the 90's at those sats anyway so I'm guessing that won't cause me major issues.

Il post my findings later when I get home... Thanks again for ur help

With zero-skew I mean zero relative to the dish. That means the actual skew (relative to the horizontal) is in accordance with the satellite the dish is pointing at.
What I mean by the wrong skew for the 3 Astra's is that those sats have a different skew. The intention of that is that the skew of the LNB of a fixed dish is around zero (relative to horizontal) if you're in the intended area of the satellite. But for a rotating dish this is not optimal. Having said that: in reality I never had issues with that for the Atstra's, although a perfect skew undoubtedly would have increased the SNR.

I hope I made myself clear; if not I hope Huevos will step in, as he'll be able to explain it far better then I do.

If USALS doesn't work the dish is aligned wrong and not tracking the arc.

Yes I understand what u mean... Thank u both, realignment def needed I think, and I need to get my head around using USALS when it's configured properly
