Which companies have run the Channel 3 services in the Hannington transmitter area
I assume you were using the Hannington Transmitter before the retune event. How reliable were the signals previously?
You are obviously in a very awkward location, what are your neighbours picking up?
It may pay to do a retune with the aerial unplugged to clear all previously stored information and then repeat that with the aerial reconnected.

Since Hannington's frequencies changed most recently, I've not been able to get COM7 or COM8 channels. I am in RG2 9FB, my wide-band aerial is pointing at Hannington but I can also receive Crystal Palace as well, which is in the opposite direction to Hannington for me, so the aerial picks up both.
I see that both Hannington and Crystal Palace now both broadcast these MUXes at CH55 and CH56 respectively. I see lots of other people in the Reading area on this thread with the same issues. Could this be caused by the fact I am receiving the Multiplex from both transmitters on the same channels at the same time?
When I do a signal check on the TV for these, it shows a strongish signal (about 70%) but virtually no quality.
I assume that means that unless the frequencies change again, due to CP's interference, we can no longer get those channels?

DVB-T2 SINGLE FREQUENCY NETWORKS AND SPECTRUM
"Self-interference places the main constraint on the size of an SFN.
In broad terms an SFN will contain coverage holes if any two transmitters within it are separated by distances exceeding the guard interval (more exactly: the distance which the signal travels during the guard interval period).
Up to a limit, it is possible to overcome this interference and regain the coverage by increasing the signal's guard interval, or by improving its robustness.
However, doing either of these will reduce the network's throughput, and it becomes necessary to trade off coverage against throughput in order to find the most satisfactory combination of the two."
The guard interval in current use for com7 and com8 is 1/16, corresponding to a maximum distance between transmitters of 67.2 km.
According to the Digital UK data for your location, linked to below your post, the distance between Hannington and Crystal Palace appears to be 82.4 km.

Hi all, I am still unable to get the Com 7 mux. All other channels I get at 100 Strength and 100 Quality, but the Com 7 mux comes in at 70 Strength and 10-15 quality, so keeps dropping out and is unwatchable. I did notice a few days ago it seemed to be working well and I had BBC News HD at 70 Quality, but its back down at 10-15 again. It seems to me a problem with the Hannington Transmission as I had no problem getting all the channels before the latest 'Change' on April 18th. I now have to watch the standard definition BBC and RT News but as Aljazeera is only HD I can no longer watch it. With me positioned at RG7 3EP I am only 10 miles from Hannington, and am over 200ft above it, so I should not really have any issue whatsoever.

One of the problems you reveal is that your signal is too strong. It must not be 100% but between 60% and 85%, no less and definitely no higher. It is good if the quality is close to 100%, but not if the signal strength is.
You might have to consider having a high gain wideband aerial, which will naturally have a narrower acceptance angle, and having it carefully aimed so it gets the signals from the wnted transmitter well but not those from the unwanted transmitter. It is a 'trial and error' process best done by measuring the two sets of signals as the aerial is swung towards or away from the transmitters, until the unwanted one is weak but the wanted one is stronger - it may not be full strength but anything within the range given abive will be fine.

Basically what js has tried to explain is that with SFNs, there are areas where the transmitters' signals will interfere with one another, which might (and note I said might) mean you cannot get satisfactory reception of them. But according to the Digital UK site for your postcode, you shouldn't have a real problem until sometime between Apr-Jun2019, thereafter it goes downhill !!!
That said, there's a couple of things for you to try/look at.
First, from the Digital UK data for your postcode, there are some mobile phone transmitters very close to you, and these may be giving you some interference affecting channels 55/56. I would contact the AT800 advice line on 0808 13 13 800 and see if you can get a filter which may help.
Second, TV aerials are directional BUT they do pick up reduced signals from the rear and also certain angles on the side (side-lobes). Sometimes a bit of careful alignment can reduce the pickup of unwanted signals, but it may also be that you may need a better quality directional aerial. Do you know anything about the aerial you have (make/model) other than it being wideband?

Looking at both your posts, I tend to agree with MikeP that there's a good possibility you may have too much signal, although I don't agree with him on the preciseness of the 85-100% signal strength. What may be 100% on one receiver may be somewhat less on another, BUT it should be used as a guide, so if you have 100% signal and somewhat less than 100% quality - as you have - then that's one of the first things you should look at.
At 10 miles from the transmitter, you really should not need any amplifier, so I would look at trying to by pass it to see what happens to your signals.
However, I also note from the Digital UK map of your postcode, there are some mobile phone masts quite close and in the same line of sight as the transmitter. These could be providing some interference to channels 55/56 especially with your amplifier! So you should also contact the AT800 advice line on 0808 13 13 800 and see if you can get a filter which may help.
