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.

Chris.SE: Thanks for the response. I certainly did notice and was able to receive COM7 channels for some considerable time (years) up to late summer last year. Previous attempts to retune usually lose the channels on the MPX, and weather conditions can affect reception/tuning. As we speak, the MPX is unavailable again. I've never quite appreciated why Ch 106 & 107 haven't been reallocated to the higher power MPXs, but I 'm only a humble member of the public and recall reading somewhere that the channels on COM7 are lower priority or have lower viewing figures which isn't surprising as they are transmitted on lower power! Cheers.

The reason those HD channels aren't on other multiplexes is simply there is no space for them and there is only the BBCB mux that is HD and also the other factor is cost. Because of the reduced coverage and temporary nature of COM7 it is considerably cheaper for Broadcasters on that multiplex. Many of us are hoping that one of the other muxs will get converted to HD/T2 broadcasts in the not too distant future, but there's no indication that will happen.
The other thing I should have remembered to mention is HDMI interference. Check that you don't have any HDMI leads close to any aerial or flyleads, especially if the aerial and flyleads aren't high quality double screened types. HDMI is known to sometimes cause interference, especially to C55 (COM7). It's an easy thing to forget when a problem looks as though it's a reception issue. That said, if you provide a full postcode we can look at the predicted reception in your locale.
