Has anyone in a fringe area checked whether skew adjustment of the lnb is different on 1N from the astra 2 birds? Is the skew set into the satellite during build or is it adjusted in orbit? Astra 2 has a "non standard" skew for its orbital position compared to most other positions - Eurobird at 28.5 is more or less standard.
So for instance any Sat over 28°e on the ground at 28°e will have 0 skew. As that is their horizon generally speaking. So for instance if your are setting up a motorized dish in the UK because you are for the most part at 0° because you are on the Merredin your reference sat will be at 0.8°w and will have 0 skew. Because that sat is closest to your longitude. The further the sat is east or west of you the more the skew you will have. If the sat is more east of you it will have a clockwise skew as you look at the dish from the from the front. The skew will be anticlockwise if the sat is west of you. All skew is turning the lnb so it matches the horizon of the sat you are looking at so the horizontal and vertical signals match up and you get the strongest signal. So any sat co located will have the same skew. |

So, the Sky channels have gone again and the transponder appears to have been turned off (I don't even get a strength reading) - has any other transponder lit up today?

From my location Astra 2 nominally 28.2E -13.7 deg EB1 28.5E - 19.8 deg Dishpointer gives -1.5deg for Due South. Scrolling through Dishpointer finds loads that vary the wrong way. There must be an attitude adjustment involved. |

I always thought the skew was related to the latitude of your home, so that an LNB in Glasgow would require a different skew to one in Plymouth. That makes sense to me because we're all at different points on the side of the Earth in relation to the satellite's position on the Equator.
Do I have that wrong? An easy way to to remember is latitude goes in steps from north to south like a latter hence latitude. |

Well 21200 (C4HD) is now sporting subtitles (which it wasn't previously) so it looks like we are moving towards the final 'Countdown'

A good test for fringe users this afternoon - we have had very dense cloud cover and the 2d signal has suffered pretty badly, on ITV2+1 it actually broke up at one stage but on 1N Ch4HD has been virtually rock steady at 65-70%signal and 100% quality on my Foxsat HD.

Strange test on the go at the moment with a very low S/R. There is a very strong signal at 11165 H 1000 5/6 (DVB-S) but nothing coming up when you scan it. Checked using Transedit but it doesn't want to lock it for some reason. Strange that they would run a test with these parameters ?

But they don't

There must be an attitude adjustment involved. Well I canīt explain that. "Well I did say for the most part." I know that a motorized dish will automatically skew clockwise as it moves east and the more east it moves the more it skews. If you think about what I wrote it makes sense. |

![]() On my Sky+HD box the signal was a little lower than normal but the quality went right down to almost zero, (never seen it do that before) with lots of picture break up. * However, on my sat-card (fed from the same LNB) there was no break up on the normal frequency and of course the the new 1N one was coming in just as strong. * I even tried a power off reset on the sky box but it didn't do anything. |

I also get a high strength and quality rating for the low-SR transponder on my FOXSAT-HDR but no channels found.

Might be that someone is using it for a feed. That would explain the low SR.
