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.
Are there any planned engineering works or unexpected transmitter faults on the The Wrekin (Telford and Wrekin, England) mast?

Robert Price: In addition to that said by Chris.SE, there are an awful lot of tall trees at the end of Crescent Road where it meets Vineyard Road. Growing taller year on year they can slowly creep into the space in front of the aerial and degrade the signal, this often affecting one or more multiplex channels, but not all. For deciduous trees, the situation can worsen when the leaves come and improve when they fall.
I wonder whether it is the trees that are the cause of your issue. That said, I don't see why trees would affect reception less at weekends!

Chris.SE: thank you for your response - following our earlier contact I emailed restoretv.uk earlier this evening which they have acknowledged - will post the outcome when 5hey get back in touch. Thanks again.

Chris.SE: Whilst waiting for response from restoretv.uk - I just thought it worth mentioning that two new and very tall mobile phone masts have appeared locally in the last few weeks situated at the Brooklands and Haygate Road - both around 800-1000m from my house.

Certainly worth a mention, and if not already causing you a problem, then they are potentially going to do so.
If as you say, your problem is less at weekends, if it's these phone cells causing your issues, it may be they are less used at weekends perhaps because the majority of users might be businesses or weekday shoppers in the area. I believe that both those masts are likely to be replacement/upgraded masts for those originally sited there on which there are EE services who are one of the companies that bought some of the 700MHz old TV frequencies when OFCOM put them up for sale!
The fact that these cells are pretty well on your line-of-sight to the transmitter means you'll likely be picking up signals from them.
Considering the age of your aerial then if it's not a Group A aerial (the original group used by The Wrekin for Analogue before DSO) then it could be a Wideband, but whichever, strong enough signals in the 700MHz band (which is within Groups C/D) will still be picked up.
One of the reasons I asked you to check the Signal Strength and Quality figures for all the multiplexes is that any extra interfering signals could be causing "desensitisation" of your receiver (or causing overload of it and/or any amp/splitter you may have) and whilst it may not be having an observable effect on all multiplexes it could be reflected in the figures. A certain amount of Errors in wanted signals can be corrected by the receiver and sometimes one particular signal could be affected to a point beyond that ability.
That can be for a variety of reasons, eg. not all aerials will pick up signals equally across all frequencies, those signals could be weaker at certain frequencies or suffering multipath issues due to effects of the ground, buildings, trees etc. between you and the transmitter. It is not as simple as one might think. The behaviour of RF signals and their reception (at any frequency) can sometimes be somewhat of a "black art"!
I think your best bet will be to persuade restoretv.uk to send an engineer out to you (on the grounds that before these new cells you had absolutely no problems, your installation is not straight forward (you haven't explained about how it's all interconnected with splitters & etc) you may not have ready access to your aerial feed or even the ability to get into your loft etc.

Ignore the fact that I appear to be in your location in my last post, I used your postcode in my settings to have a quick look at the sighting of mobile phone masts and the terrain etc in your locale and should have removed the settings before posting !!

Chris.SE: I have now had a telephone response from resolvetv.uk - verbal diagnosis along with confirmed major local upgrades have indicated that these upgrades are very probably responsible for the issues I have been having with C23 channels - consequently they are posting a filter which should arrive within the next 5 days. Hopefully this should cure the problem - fingers crossed. Many thanks for all your assistance and advice.

The filter should be fitted between the aerial and any other amp/splitter etc that feeds any of your equipment.

Chris.SE: The filter arrived from resolvetv.uk this morning - now installed and the signal strength on all C23 channels that were affected has dramatically increased - all pixillation has disappeared. Thank you so very much for your input.

Well, I'm so glad that the problem is solved. What I've found interesting about this situation is how it affected the lower frequency channels more without appearing to have affected the others.
That was one reason why I wanted to see the figures for the other multiplexes (without a filter) as it may have shown they were affected but not to the extent that the receiver couldn't continue to decode the pictures successfully..
Seeing those figures early on may have made the cause more obvious and a solution achieved somewhat quicker.

All channels completely gone now. Just a message saying no strength
