Yesterday many of the comments I spotted where things were working said they improved stability by adjusting the skew and 'tweaking' the dish slightly. Seems the alignment of the dish and its setting (skew for example) have to be spot on where as on the current system you can afford to have them out a little and it still works.

Martin963 Posted November 24, 2012 Share Posted November 24, 2012 Skew is desperately important - the more the satellite is away from due south (as viewed from the location of the dish) the more it matters.A bit of history here - when 2D suddenly became so "important" (ie when the BBC moved from 2A to 2D in 2003) skew really became a problem. SES would never admit to this (why they have to be so d*mned secretive the whole time is beyond me) but the signals from 2D were further skewed than the calculations from pure geometry would predict. This meant that to optimise reception of 2D one had to twist the LNB (clockwise as viewed from the front of the dish) further than seemed "proper". As far as I can see 1N reverted somewhat to normality, and one would assume that 2F would be similar. By normality I mean the correct amount of clockwise skew. But for those who optimised things for 2D it may now be necessary to re-tweak the skew if reception is a bit marginal.Does that tie in with what you've observed Jako...?

g8vkv Posted November 24, 2012 Share Posted November 24, 2012 I've been in touch with a chap about 60km east of us who says his 11023H holds up all day with a 1m dish, so that gives me hope that things aren't necessarily terminal.It's true that our dish setup is less than perfect. It wasn't especially aligned for maximum signal (just until it was "OK") and also the LNB is held in place with sticky tape (the clip is broken)So it looks like getting the ladders out again.

Daft Doctor Posted November 24, 2012 Share Posted November 24, 2012 Hi again and thanks to all you technical guys for the information. Just to summarise for me, as far as we know are there any channels which are as of now being exclusively transmitted from Astra 2F? Insight much appreciated.

Martin963 Posted November 24, 2012 Share Posted November 24, 2012 As far as I know it's still just 11023 MHz. I think there may have been tests on a few other frequencies but not ones that would be visible on a normal box. And that is just hearsay to be honest.I think if the major swap had taken place last night (as predicted by some) we'd hear a lot more squawking from the Iberian peninsular this morning.....

Jako Posted November 24, 2012 Share Posted November 24, 2012 As far as we know nothing has changed overnight. Indeed because the forums are still operational [:)]All Astra satellites have a different skew than all the other satellites, don't know why. The skew has not changed, but a weaker signal may simply need finetuning of both dish and lnb for many installations. Link to comment Share on other sites More sharing options...
g8vkv Posted November 25, 2012 Share Posted November 25, 2012 Anyone know what's going on?All signals much stronger since about 03:00 - typically SQ 100/100 or 100/90.It's almost as if both 1N and 2F are running together - but I didn't think you could do that because of phasing, clock synchronisation and all that?Very odd and I'm sure it won't last.

Danny Posted November 25, 2012 Share Posted November 25, 2012 No change from yesterday for me here. Still broadly the same readings.Don't forget that cloud and other atmospheric influences will give fluctuations in signal levels over the course of any day.Danny Link to comment Share on other sites More sharing options...
g8vkv Posted November 25, 2012 Share Posted November 25, 2012 Danny ..You're very likely correct - maybe I got over excited for a while.However, I've never noticed 1N signals this strong before and the 11023H signal is now sitting at an SQ of 100/60 (previously a stubborn 75/60 until it disappeared)A bit interesting.

Jako Posted November 25, 2012 Share Posted November 25, 2012 You are not alone. A guy in north-east Italy went from 0 yesterday to 80% this morning. Maybe the switched back to 1N[:)]edit: checked German reception and they only see gradual improvement. So the signal is not back on 1N, it might just be due to the slight swinging of the satellite that has a major impact in the south-east.The swing-period seems to be around 3-4 hours.

g8vkv Posted November 25, 2012 Share Posted November 25, 2012 Jako -It's all quite interesting.I was up at 03:00 this morning (I have "man-flu" and needed a cup of tea) and noticed that the (presumably) 1N signals were all (unusually) very strong - lighting up the SQ bars on my Hummy. This is still the case, 8 hours later, all still showing 100/100.The 11023H signal has also improved in strength, but not quality (100/60)I just wish they'd get on with it!

Quillan Posted November 27, 2012 Share Posted November 27, 2012 I looked around the forum that are interested in this about 08:30 this morning and all was quiet. I think we will sse a lot of activity when it happens. [;-)] Link to comment Share on other sites More sharing options...
Jako Posted November 27, 2012 Share Posted November 27, 2012 2b or not 2b has no definite answer yet. Changing satellites goes unnoticed on the ground when both satellites use the same footprint. There are some reports of reception changes, but the weather may cause that. The big difference would be the move of FTA channels to the UK spotbeam. It appears the new beam is even tighter than thought because reception in the fringe area's is not stable. Apparently 'good reception' can easily turn into 'no reception' a few days later.

krusty Posted November 28, 2012 Share Posted November 28, 2012 Goal posts have changed , so not tonight my dear.Astra 2F Update 28/11/2012 : No more updates yet on the "big migration" of UK TV channels from Astra 1N to Astra 2F. The first rumoured date of between 23-26 Nov did not bring anything. The next rumoured date is first week in December. Until then only the one single frequency, carrying two BBC HD channels, is the only UK TV frequency that is live on Astra 2F. Link to comment Share on other sites More sharing options...
crabtree Posted November 30, 2012 Share Posted November 30, 2012 This from "SES-Astra" facebook page "Services are currently being transferred onto Astra 2F, BBC (Transponder 2.061) has been migrated to 2F whereas Channel 5 (Tp 2.057), ITV (Tp's 2.059 and 2.063), and Channel 4 (Tp 2.068) will move to Astra 2F next Tuesday. This will then mark the completion of the transfer"Probably those of us with freesat and/or freesat+ boxes will see the BBC change overnight tonight, during normal housekeeping. I am not sure whether by Tuesday they mean Monday night to Tuesday, or Tuesday night to Wednesday. Link to comment Share on other sites More sharing options...
Martin963 Posted December 1, 2012 Share Posted December 1, 2012 Nothing is certain, so I offer this information with a certain amount of salt.....If a recent statement from SES is to be believed and taken literally then a lot of the BBC services (and most ITV and ch 4, apart from HD) won't be moving for several more months.There has been a persistent rumour around that suggests that 2F only covers frequencies above 10.95 GHz, and that it will be 2E that eventually covers the old "D band"; now most BBC stuff is indeed below 10.95 GHz, so if you interpret the SES statement carefully it suggests that ONLY the frequencies mentioned in it will be moved at the present time. It fails to mention any transponder below 10.95 GHz.This would mean that there was no hurry to move 1N to its proper home at 19.2 deg E and that SES are happy to leave it where it is until 2E arrives in the spring. If all that is correct we are only witnessing a partial migration away from 1N and Quillan (for example) will retain the BBC for a few more months come what may. The real agony might start in the spring.As I say, this is what an informed reading of the SES statement suggests, but I offer it on the basis that it may be completely wrong...http://www.a516digital.com/2012/11/ses-ends-week-of-speculation-uk.html?spref=tw Link to comment Share on other sites More sharing options...
Wilko Posted December 1, 2012 Share Posted December 1, 2012 As of this morning I only have ITV channels all BBC are no signal............what do I do, re-align dish or buy new dish ?

Martin963 Posted December 1, 2012 Share Posted December 1, 2012 Oh really? Well that blows my last post out of the water!!I'd wait a couple of hours and we'll see if there are any other reports. If not maybe your dish has moved...?Laters - probably local to you Wilko, others confirm that no BBC switching took place overnight. Link to comment Share on other sites More sharing options...
Jako Posted December 1, 2012 Share Posted December 1, 2012 "low" frequency test signals are reported from 2f, so the "d-band problem" seems fiction as well. We just have to wait. There are no other reception problems reported (yet). Link to comment Share on other sites More sharing options...
Martin963 Posted December 1, 2012 Share Posted December 1, 2012 Well I did clearly state that it might need to be taken with a pinch of salt. But it's odd that SES appear not to mention the migration of any transponders below 10.95 GHz in what they have said..... Link to comment Share on other sites More sharing options...
