Your arrogance is beyond, you are so obsessed with your 70/85/100% figures and completely missing the point of the situation, apart from which, I will repeat 100% of an arbitrary figure - you have NO idea what margins it may represent. And in addition I was already talking about the possibility of overload in my post on the 8th April before you came along with your obsession. You really should stop criticising and try and be constructive, almost every post where someone has stated they have 100% signal and you have responded, you've immediately said that's too much signal without any further analysis of the situation. Just give it up.

Thanks for the update. You have approached this issue in just the right way. Shame about C55, you may be in one of those not spots due to it being an SFN, however Winter Hill is still listed for Planned Engineering, so without touching the gain control at present, it may be worth periodically trying a manual retune on C55 as it's impossible to say if that engineering is affecting C55 at your location. Undoubtedly you'll still have 100% signal on the other muxes as previously mentioned when you had 90% on C56, but as long as the quality is 100% for all that's the main thing.
Your TV must have a better front end than that BT PVR if the latter was unable to decode C56 at anytime whatever % signal you had. Some are undoubtedly better than others.
There's been some reports about the possibility of Tropospheric Ducting over the bank holiday & next few days, so I've been having at look at some other UHF channels to see if any DX reception was possible. One channel yesterday was giving me 14% signal and 0% quality, yet amazingly I had no break-up for the time I was watching !!! I couldn't believe it was performing so well. The day before, the same channel had occasional break-up but still very watchable.
Let us know how you get on if things change.

That's what I would have expected with 0% quality! But I can only guess that the particular design (probably in firmware) has specified that an error rate above level "x" will be 0%, but the error rate "x" is still not quite bad enough for it to decode!
As for the dubious channels, well it takes all sorts :o say no more.

That's for that gem of info. :) That'll make some interesting bedtime reading when I'm a bit bored ;)

How nice for you, the real world in the preceding posts just doesn't agree with your earlier comments, so give it a rest.

Exactly that. I was waiting for an appropriate time to mention a particular example, and now is the time.
I came across someone's (quite cheap) PVR - it required a microSD card to record.
No matter what signal strength it was actually fed with, it ALWAYS showed 100% strength (I did wonder after a while whether it was actually showing quality rather than strength - it wasn't showing "both" figures).
This box had an extremely good picture quality - far better than the Samsung TV it was plugged into, and excellent quality sound. It was a brilliant little HD box, never had any problems with picture or sound breakup both before and after DSO, until its PSU failed - sad demise.

Also be aware that there are two things that could disrupt your reception at this time -
1) Belmont is listed for Planned Engineering this week with "Possible weak signal"
2) There's the possibility of Tropospheric Propagation disrupting reception for a couple of days, see -

I've been notified of your post about LBC from Lark Hill, but can't find the post which is supposed to be here rather than the Lark Hil;l page! LBC is on the Digital One multiplex broadcast from Lark Hill.
Trying to discover faults on Commercial multiplexes is like trying to find needles in haystacks. The BBC did report a transmitter fault from 12:29pm to 1:11pm on 8th Apr 2020 when it was off-air, but i can find any further information about Lark Hill.
If you are still having problems with reception from Lark Hill, you'd probably be best phoning LBC and report the problem to them as they would know exactly who to contact about any transmitter fault affecting their broadcasts.

Mardler :
The transmitter is listed for Planned Engineering this week with "Possible service interruptions" (which might include what seems like low power). If you happened to have retuned (not advised in those circumstances), it may have cleared the correct tuning and you will have to retune at some point when transmissions return to normal.

John:
It's not "our" signal, this is an independent help site, that said your predicted reception is from the Sutton Coldfield transmitter which is currently listed for Planned Engineering with "Possible weak signal" so this may be the cause of your issue. I am surprised that work might be continuing over the bank holiday weekend, but as Arqiva never give details of the work, it may be essential.
However, there has also been some talk of the possibility of atmospherics disrupting reception over the bank holiday - Tropospheric Ducting - see How clear skies and fine weather can affect your TV reception | Help receiving TV and radio and the linked page.
If you lose signal and try retuning you may get signals from a different transmitter and lose them again as the propagation changes, and then you'll have to retune again and maybe unsuccessful in getting your regular signals back until the disruption subsides.
