The symbol shows the location of the The Wrekin (Telford and Wrekin, England) transmitter which serves 280,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

I'm afraid Arqiva never say when work will be finished, nor what it entails, a lot of which could be weather dependant.
There is additionally a little bit of tropospheric ducting around which might add to the problems for brief periods causing interference from distant transmitters in the UK or Europe.
Paul Robinson:
With signal strength at 100% & such low quality that sounds like you have a lot of interference.
How long have those conditions been persisting?
What sort of figures do you get normally?
Have you had a postcard from https://restoretv.uk at all?

It's only been happening last week or so, on HD I normally get 100% strength and 98-100% quality. Many thanks for the reply and explanation

IIRC, The Wrekin was recently first listed for Planned Engineering in the 2nd week of July, whether or not the work is complete is never certain as although it seems it's not listed next week we know the lists can be inaccurate from time to time.
What Signal Strengths and Quality do you normally get for the other multiplexes?
100% signals can sometimes overload the receiver front end which can cause pixellation and sound break up under some conditions, but what you should have is 100% Quality all the time under normal conditions.
As you used to use the Brierley Hill transmitter (assumed from your previous posts) have you replaced your aerial? Do you have a pre-amp/splitter?
If both, I hope it was a Group K aerial. If the amp/splitter has a variable gain control then turn it down a touch until signals strength drops but Quality remains at 100%. Wait of course until all your signals are back to the normal that you usually see.
I don't know what sort of reception you are predicted to get as you haven't given a full postcode (so can't advise on that point), then even if you have only re-orientated your aerial and it's not a Group K, put your postcode into the "Not sure" selection on https://restoretv.uk and if it says Yes, then get a free filter from them in case you are getting any mobile mast interference.

Thanks Chris, yes i used to used to use Brierley Hill Hill transmitter move back to the Wrekin, due to building work. Fortunately I've just done a rescan energise and I'm back with all channels. They seem to be running at around 90% strength and 100% quality. On some of the weaker multiplexers I normally get around 60% and 40%, and that is now the same.

TF13AF - Wrekin Transmitter - Every channel on C23 has been virtually unwatchable for weeks due to pixillating and sound distortions - today is absolutely worse than ever - please advise when will this problem be restored to a watchable service?

Robert Price: The post above yours warns of engineering work taking place at The Wrekin this week. Unfortunately they never say how long the work is due to last as it is dependent on weather conditions and other factors (engineers cannot climb up the transmitter mast in heavy rain or high winds etc).

Thank you StevensOnln1: I am fully aware of the post ahead of mine which, if you check back, is the same post that has been made by Transmitter Engineering regularly for many weeks and months - the problem has been getting progressively worse now rendering every channel on C23 virtually unwatchable - my question was when will it return to some sort of normality.

The transmitter wasn't listed during the first two weeks of August, nor during early July. Before that it was the latter part of May early June. It would seem that a significant amount of work has been needed there otherwise it wouldn't have been listed as much in recent months.
However, that said, you are only 4km from the transmitter and should not be suffering any serious problems with reception whereas your post implies you've had continuous problems with the ITV/C4/Ch5 channels carried on the D3&4/PSB2 multiplex on UHF C23. Has it been continuous or has it just been periodically?
If continuous, I think this would point to some sort of local problem as if it were a transmitter issue there would be many posts complaining of the same issue.
If periodically, has there been any pattern to this, eg. specific times of day on a regular basis?
Are you having any problem with channels on the other multiplexes?
Can you look in your TV Tuning section, possibly Signal,Test (depends on your set make/model) and quote the Signal Strength and Quality (or Error) figures) for each UHF channel's multiplex, which are C26, C23, C30, C41, C44, C47.
Where is your aerial located? Has it been moved/disturbed? How old is it (roughly)? Is the downlead in good condition?
Is it a Group K aerial do you know? Have you got a free filter fitted as you may have mobile phone transmitter interference as you should have received a postcard from https://restoretv.uk/ according to their website?
Do you have any other equipment connected to your aerial - amp/splitters, recorders etc.? How are the connections routed? Do check that all coax connections are good, not loose or corroded etc.
Has anything appeared on the line of sight between your aerial and the transmitter, eg. buildings, scaffolding, have trees grown bigger, any solar panels installed etc.?

Chris.SE: Many thanks for the useful information you have provided. I get absolutely no problems at all with anything other than the channels carried on C23 - everything else is absolutely fine. The problem does seem to recede at weekends. My aerial is in my loft space where it has been for the last 24 years and has not been moved - nevertheless I am arranging for it and any associated cabling to be checked over - there is nothing else apart from my YouView box and a second TV connected. Thanks again for your assistance.

I suggest that you contact https://restoretv.uk/ first. Tell them that you are having problems. If you haven't got a filter they may send you one or may send you an engineer free of charge.
