I and my neighbours have been having no signal or pixelating since at least 6.30 this morning 22.12.21
It's all stations, it sometimes comes on for a few minutes then goes off again.
My Ariel is on my roof and has been working fine until today!!!!
Help would be much appreciated!!!! Thank you

there don't seem to be any troposphere problems Tropospheric Ducting Forecast for VHF & UHF Radio & TV
explaining poor reception
Have reverted to using ITV hub and other internet based 'apps'
(ukfree.tv comment section itself seem to generate errors from multiple browesers - hence my earlier duplicate postings)

On the contrary paul, there has been moderate Temperature Inversion/Tropospheric Ducting affecting large parts of the UK for several days, it sometimes accompanies high pressure.
Do NOT retune, it will more likely remove your correct tuning.
These conditions are predicted to ease late on Wednesday by the end of the night
Despite the incorrect spelling, this link does work - simple technical explanation

Essentially it results in interfering signals from other transmitters in the UK or Europe reaching you and so your wanted signals are disrupted. It won't necessarily affect all multiplexes or necessarily at the same time if more than one. It can last for seconds, minutes, sometimes hours or longer.
The BBC have had a warning on their Works and Warnings page for a few days, and Freeview had added one on Wednesday (better late than never!) but at the time it was then mainly affecting the S & SE.

OK is there a better web-site than the one I linked , which will show ducting forecast ?

Hi paul. Do remember they are all general propagation predictions and it doesn't mean that one WILL be affected, sometimes just bands II & III may be affected and not IV & V, sometimes the other way around, sometime all or none!
dxinfocentre is one of the ones I refer to, also Europe | Tropospheric Propagation Forecast
It's worth keeping an eye on Problems with Freeview reception? | Help receiving TV and radio as the BBC sometimes put a Works and Warnings note up (there's been one but it will usually disappear when conditions change).
I do look at Updates and alerts | Freeview for other things but they're often unreliable for this sort of thing (always after the event, so to speak, as with some other things they put there!).

Experiencing intermittent pixelation on channels this evening. Not as as bad as the problem we had on the 23rd December.

It's Temperature Inversion/Tropospheric Ducting again I'm afraid. See my previous posts before yours if you want more detail. It's unlikely to clear completely until some time tomorrow and then it could still be a bit intermittent for a few days.

It's likely to a combination of factors. Unfortunately weather conditions again - see the post before yours, applicable again and it's reference to an earlier post if you'd like more detail of this type of problem.
Sandy Heath has also been listed for Planned Engineering this week, so some of that may disrupt reception.

Do you ,know when the planned engineering work on or near the transmitter Sandy Heath,Milton Keynes is complete? Channels keep coming and going for us, and have done for weeks! Thank you.
