The symbol shows the location of the Oxford (Oxfordshire, England) transmitter which serves 410,000 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 trying to get more detailed information on Planned Engineering seems to be a waste of effort as "Freeview" generally don't seem to have a clue (the best they seem to say is it may affect your reception!).
Whether the DigitalUK staff know what Arqiva are doing in detail (without asking) is anyone's guess, I get the impression they don't, as the last time I pursued a fault with them it was like banging a head against a wall and ended up with Arqiva denying there was any fault - despite the fact that the fault mysteriously got rectified at the crack of dawn on the first day of "Planned Engineering" (ha ha).
As far as the actual problem is concerned, it depends on exactly what they are doing at the transmitter. Whilst a weak signal itself shouldn't cause what you are seeing, whatever they need to do may require the transmitter power to be reduced at some point, I'm not a transmitter engineer!
Past experienced suggests that contacting the broadcaster about a persisting problem gets quicker action than anything else, as they know exactly who to get on to, to get it sorted.
There never has bee any clear information about any faults for any of the commercial transmissions whether it be Radio or TV, only the BBC have publicly accessible reporting mechanisms for anything affecting their own broadcasts.

When I went to bed last night the channel was still borked, this morning it's back to normal. I guess I'll put it down to the engineering works. I am astonished that such a major Freeview channel can get so broken and yet it goes almost unremarked. Oh well.
Anyway, thank you for your informative responses.

We have lost ITV, Channel 4, 5,6,10,13 - All C44 broadcasts for approaching a week now.
MK18 2HR post code.
Any thoughts?

Well that is very strange. I can find no current or recent faults listed either by Freeview or the BBC for the Oxford transmitter and it's not currently listed for Planned Engineering.
I suggest that you check all you coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. Flyleads can be a common problem, try swapping them. See what signal strengths (if any) and quality you are getting for the multiplexes shown in your TV's tuning section, this might indicate potential issues with your aerial or downlead. Also check that your downlead looks undamaged and that your aerial seems intact and pointing in the correct direction.
Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.
If that all seems ok, I suggest you carry out a retune as follows - unplug the aerial and carry out a full automatic retune which should clear all previous tuning as no channels will be found. Switch off the set for 10 minutes.
Then plug the aerial back in and switch on and repeat the retune, hopefully all channels will be correctly restored.
Also note that the correct UHF channels for Oxford are C41, C44, C47, C29, C37, C31, C55, C56, C46 in the order PSBs1-3, COMs4-8, Local. Unfortunately the site owner has not had the time to update one of the tables at the top of the page as a result of the 700MHz clearance.

Oxford is now listed for Planned Engineering with "Possible weak signal", so there's obviously been some sort of issue.

After the demise of com8 i was hoping for a better signal but channel 55 com7 signal from Oxford is rubbish - the power remains so much less than the main channels.

If you provide a full postcode we can look at your predicted reception from both Sutton Coldfield and Oxford.

I don't understand it. There have been two FREEVIEW channel updates recently and I see I can now again get BBCHDNews on Freeview CH107 (MPX Com7 transmitted on low power from Beckley). I lost all the COM7 channels from mid to late 2020 and had assumed the reorganisation meant that that was the end of that.
So why can I receive COM7 again. Using a wideband highgain aerial with high signal strength (10) and low dropout on most of the other channels. So no changes here.
Be good to have an explanation please?

You may have been able to receive COM7 a while ago but not noticed.
As you probably know, COM7 is a temporary multiplex, which will close by the end of June 2022 (as per the current licence) if not before. The frequency it uses is allocated for Mobile "SDL" usage. IF when the 700MHz frequencies are sold (due soon), any MNO that buys those particular frequencies will need to develop cell equipment, and suitable handsets need to be available as well. This will take time, but as soon as an operator is ready to use the frequencies, 3 months notice may be given for COM7 to close.
The only other reason COM7 may close earlier is for commercial reasons as Arqiva decided for COM8 last June.
COM7 operates as Single Frequency Network (SFN) on UHF C55 along with the other 25 main transmitters that still transmit it. This means there will be some locations where the signal you get is affected by other transmitters, so if any of those signals are off-air or low due to transmitter maintenance or faults, this can change your reception.
If you happen to retune (or the set auto-retunes) when there is no or very weak signal, it usually just clears the correct tuning, and you may not get the signals until a further retune. If those signals are normally weak, auto-retune wil sometimes miss them, so a manual retune on UHF C55 should be tried.
Hope that information helps.
