Seems to be a widespread issue on MUX2 (ITV1, C4 et al), Ridge Hill transmitter, mostly daytime/early evening and then settles down. Loss of quality, not strength - 2 decoders here fail to pull anything, the third works but with intermittent pixellation.
It's not an issue on anyone's particular installation since it spreads across Worcestershire (where I am) into Gloucestershire (where the poster above is) and affects other people I know. No work is reported that I can see, but there's clearly something afoot... I presume DSO-related but simply not being mentioned?

Briantist - I have been reliant on Ridge Hill for 21 years now and used to be one of the feedbacks to the control centre at Emily Moor for ITV and Evesham for BBC. The performance record over the years for analogue has been appalling with one fault, (black line flashing) on ITV lasting for 18 months. After a lot of complaints, they eventually traced it to one of the 2 microwave links between Bristol and Ridge Hill; the other hop being from Abingdon to Bristol. Part of the problem was the central monitoring equipment did not show the subtle/intermittent faults.
Channel 4 also had problems with sound hum and this was eventually traced to on one of the receivers, as it relayed Sutton Coldfield. This lasted for about 3 months. The BBC reserve receivers were pointing to Mendip so at a time of high pressure, the local midlands news could flip over to BBC West from Bristol.
The other thing about analogue Ridge Hill was that changeover to the reserve transmitter gave about a 30 second break. My neighbour who worked for EMI was part of the design and build team for the original UHF aerials at Ridge Hill but that is another story.
Early digital transmissions from Ridge Hill did not go well. They started at 5kW for the BBC but later reduced to 2kW much to the anger of viewers who could not receive the transmissions at the reduced power or had to upgrade their aerial.
As from the 6th/20th April with the new transmitters, let's hope all the problems are in the past; we shall see.
Regards

@Briantist - thanks for the pointer, but I'm not sure that my washing machine or mobile 'phone is responsible for affecting an area of perhaps tens or hundreds of square miles, let alone for a couple of hours at a time... there's clearly an unpublished transmitter issue or a more widespread EMF interference issue if the reports I'm seeing are all true.
I was merely pointing it out for the benefit of other people in case other folks are scratching their heads at a sudden fault on these channels. It may be relevant.

Bagpuss: OK. If you don't wish to solve YOUR reception issues, that's fine with me.

I tend to agree with Bagpuss Brian as I also referred to your helpful guide but to no avail.
Unfortunately, the problem has been more subtle and I certainly would have liked to solve my reception issues. Hears to the 20th April.

DaveCheltenham: I simply mean that trying to say that "more people than me have a problem" is no way to diagnose what the problem is.
