@tothbros tp 48 10818v not move it

@tothbros tp 48 10818v not move it

all 1N tp's are strong here still, despite the rain, so basically tp 41-56
but no sign whatsoever of 2f, nothing, solid 0%

Even with only the first 50 or so reports on the map some interesting trends are coming out.

Theres a distinct arc of green dots appearing - (these are the up to 1m dishes) Im doing most the UK as just one dot - no point filling the map up with useless detail. I would include any reports from the far north of Scotland if we get any

Probably most unexpected to me is the positive reports from the Canary Islands and the negative ones from around Barcalona.

BTW - the negative reports from Malta come from the forum facebook page, you wont find them on the main forum.

Looking at the footprint for 2F, I think 28e is a goner for eastern europe. The pan european beam covers nowhere near here.

Having read the various reports from my region it is clear there is no consistency here i.e. the "problem" TPs vary by installation. This suggests that all will in fact be receivable with appropriate tweaking. Could I therefore ask the more technical people here to post a few suggestions for us amateurs as to what we can tweak without completely b*ggering up our dishes? Many thanks.

Leave any realignment to the professionals! ;)

You could try stringing the dish with monofilament fishing line to see if the reflector is still straight, and tweaking the lnb wont do any harm if you can reach it without leaning on the dish face.

I can easily reach the LNB. The Black Ultra has a very long "neck", so I guess the two adjustments available to me are "distance from reflector" and "scew". Might have a play tomorrow whilst the OT is at work. Permanent marker pen to mark the existing position of everything me thinks! I will definitely NOT be touching the azimuth or elevation of the dish as that would be passing the point of no return!

 

[Analoguesat]

Yes mark everything before you start - and good luck.

And only move it a tiny amount each time.

The BBC 1 HD channels on 11.023H are tests for Scotland and Wales and cannot be tuned in on a Sky box.

I understand the longer term objective, is to transmit the BBC local news in HD - at least in some regions.

Indeed, when I was adjusting my LNB on my 1.8m in Helsinki for Astra 2D (back in the day), I could hardly see the LNB move when I was trying to fine tune it. Perhaps rotating it less than a millimetre at a time from the original mark.

Yes, so far only Northern Ireland is live, Scotland and Wales are testing, and England won't be getting regional HD channels for a long time since there are so many and it's too expensive to broadcast them all in HD via satellite.

Are the Scotland, NI and Wales BBC One HD versions going to occupy the 101 position in the Sky EPG?

Without wishing to drag this thread further off-topic, I'm not sure to be honest.

Yes. I believe that the NI version already does.

I agree, Canary Island reports are a bit of a surprise - but currently a good one . However, I want to see more time pass and more signals taken up by 2F before I'm content with what we do and do not receive. Clearly it is also dependent on the equipment being used.

And especially how well apparently equivalent equipment is set up.

Absolutely.

Updating FW on meters, thought I'd try a test. Posting measurement parameters of aforementioned transponders slap-bang in the middle of intended footprint (Uk), 0.43m dish for reference or comparison.

I'm sure it's already buried somewhere deep within one of the prequel Threads, but can somebody please remind us of the next phase in the Sat Shuffle?
