Hi Chris SE
On Oct 23 two signals from EM disappeared CH56 was moved to 39 not 37 and the other one CH?? moved to 37. Are you sure 56 is still there because I believe it is released to 5G? This is the EM map I ended up with:

37 COM8 HD -
39 Local -

44 PSB2 D3&4

51 COM4 SDN
52 COM5 ARQ A
My next door neighbour has a chimney aerial pointing to EM and I have measured the signal at ground level to be about 56dBuV, most likely higher on the chimney. I agree EM should be my desirable transmitter but the house is located just below the line of site horizon. We are about 200m above sea level whereas Bilsdale is 600m so there is a very strong signal from there. Its all down to the topology.
As for the loft aerial its a personal choice plus its maintenance free and storm proof. The 84 and 69 measurements are inside the house at the TV points and are values are after amplification. The varying quality on arises from the EM aerial. What I did notice is that the Optima L20F has been replaced by a L20FK which suggests that the final map will see all channels above 48 released to 5G.
The Vision amp says its input should not exceed 70dBuV so I'm well inside of this but clipping may be taking place so I can't rule this out. The mapping is all over the place at the moment a proper mess and I don't think the Freeview team are properly clued up I know because I rang them on the day. Looks like I'm in for some more fun to come next week. This is the current Bilsdale map being used. I added EM 39 to get LCN CH7, Leeds TV.

I mentioned using two aerials: a Group W and a Group B. The aerial signals were combined using a Mersat BZT G687 658D 2 way splitter multiplexer. Because this is a passive device and the power pass leg is not used inputs and outputs can be transposed meaning that the single input demultiplexes to two outputs. The aerials were connected to the two outputs and the input was connected to the Vision amp input. Its output feeds signal to the house distribution amp and which receives 5v to power it.
The reason why TV auto tuning didn't work is down to the numeric order of MUX channels. TV auto tuning begins with CH21. BBCA is on EM CH47 but 'interference' from Bilsdale BBCA CH26 means that the TV database on a first come first serve basis registers BBC One Newcastle. CH47 is then ignored as a duplicate channel. A similar thing happens with EM BBCB on CH41, Bilsdale BBCB is on CH23 so CH 41 is ignored as a duplicate channel. Not much is said on this medium about what actual channels should be used for manual tuning it would be helpful when cross channel interference is a problem.

John:
First, I meant to say in my previous post that the channel listings here on this site are incorrect, the owner here has not managed to correctly keep up with the changes, there's over 1100+ transmitters in the UK. The Freeview site is normally the accurate place to refer.
2nd, there's probably a bit of confusion which maybe I should have clarified in my previous post about EM. The was a multiplex on UHF56 which moved to UHF39 according to DigitalUK's documentation, BUT this is a Local multiplex identified as L-LDS (LOC1) not COM8. At the same time COM8 which was on UHF34 moved up to UHF56. Try a manual tune on it with your EM aerial. COM8 carries programmes such as BBC4 HD, QVC HD etc.
For a full list of which channels are on which Multiplex see Channel listings | Freeview
I'm afraid as I'm not there I can't confirm, I can only go by DigitalUK/Freeview documentation - there's two places that is stated - 700MHz_Clearance_Q4_2019_Yorkshire_v2.pdf and the current Detailed Coverage Checker lists as I detailed how you can see them in my previous post. Unfortunately the link to that pdf document on the amalgamated website is broken and it's not possible to download copies of that atm. Freeview have been made aware, but how long it will take them to fix it is anyone's guess as some other issues I pointed out to them months ago (in writing) are still the same!! So try that manual scan of EM UHF56.
Autotuning is a well known problem where more than one transmitter and/or region can be received. Manual tuning is the only real option these days. Again the Coverage Checker will tell you which UHF channels to use.
Your point about topography is well known and taken, another reason why when looking at the Coverage Checker putting in your house number/name (don't post it here) can make a difference to the prediction. I can only do a general check on the postcode which terrain plotting on here gives (a mean?) 248m (at 10m chimney height), Emley Moor is 575m, Bilsdale is 674m and with those numbers there's supposedly clear line of sight. I wouldn't have expected that if you are slightly below the sight-line it would have had significant impact on the quality. On which multiplexes are you see the quality variations?
Interference, too weak, or too strong a signal especially when lots of amplification is involved, or a poor connection is a more usual cause. I would do a test from one aerial direct to one set to see if the quality variations continue.
It's also worth saying that the Coverage Checker is only a prediction and there have been cases where it's just not right for some obscure reason. However with the COMs 7&8 multiplexes as SFNs there is inevitably some reduction in coverage because of the way SFNs work, so I would not ignore the fact that COMs 7&8 from Bilsdale are predicted to be unreliable at your location one all the retunes occur.
Finally - I think ;) 5G, - Group K aerials will be the norm in due course, but where the temporary multiplexes COMs 7&8 continue to transmit, a Group T /Wideband is needed (Group K is no good for them, especially as they are often lower power). At present, no final date has been announced but it's currently expected that they will all close by sometime in 2022, at present they are allocated in a gap between the Downstream and Upstream 5G allocations. If you are interested, look at all the documentation associated with the 700MHz clearance program.

There is a nice graphic at the top of this page Will I need a filter when the 5G mobile broadband services start in 2020? | free and easy which shows 5G and DTV allocation.
There is one bit of information later on that page which I think could be misinterpreted, and that is where it implies the BBCB mux will be on UHF47 or 48. Quote "Be using the BBCB multiplex for Freeview HD (as they will use C47/C48)". That is not the case for most of the transmitters, the mux is on other UHF channels.

Hi Chris
The graphic seems to confirm that EM CH56 is gone. I went around to measure my neighbours signal strength at the back of their TVs which is about 45 dBuV but only because they have tapped off parallel connections from the main down feed into three or more rooms. Need I say more?
I went to trouble of mapping the LCN landscape one aerial at a time. The process was disconnect the TV aerial and auto tune to clear the TV database. Then to reconnect the aerial and manually retune one MUX CH at a time for CH21-69. The results were:

Quite a lot of duplication with the Group B aerial's poor forward/back rejection losing only about 10dBuV. The mapping for the Group W log periodic was a lot cleaner with only one duplicate because of high forward/back rejection:

I seem to be picking up a CH22 signal that duplicates CH29 and I don't know why or where its coming from, presumably from Bilsdale?

Hi John,
You've confused me. I think you've misread the graphic! We are in the "Interim 700MHz Plan (Freeview HD in Centre)" period at present, and that shows UHF 55 & 56 between the Uplink and Downlink blocks. This is expected to continue until 2022 or until such time as OFCOM auction the SDL block and announce anything different.
Also, you might not pick up UHF55&56 with your group B aerial (perhaps not enough gain especially as COM8 is only on 51kW).
I assume the results are with it still pointing at EM. I'm wondering if pointing your group W at EM and trying for COM8 will work as it might have less gain at UHF56. COM7 isn't moving to 55 until Q1 next year, as you know it's currently on 32.
I cannot be certain where this D3&4 mux on UHF22 is coming from. Bilsdale is not planned to use UHF22, nor are any of the other transmitters that you might normally get, but that signal strength does suggest it's Bilsdale. They could be doing some testing even though there's supposedly no Planned Engineering there this week, in preparation for the retune on the 13th. D3&4 is due to move to UHF24, but I'd guess they can't use that to test as it would cause interference with Idle using UHF24 for PSB1 moving to UHF23 on the 13th.
Don't forget to experiment with your Group B (& later perhaps the WB) to EM direct to TV and via one, then both amps to get a better understanding of any quality fluctuations. That Quality result for EM BBCB is odd!

Just re-reading the above, I'm finding it odd if you're not able to get COM8 on UHF56 if you used to get the Local Mux when it was on UHF56 before the last retune.

Hi Chris
I agree the missing TV signal on EM CH56 is likely down a lack of gain on the Group B aerial however, on the 23rd the Group W aerial was pointing at EM when CH56 disappeared. I swapped them around later on. On the EM LCN mapping I noticed COM8HD LCN 56,67,74,78,86,92 are missing. As I'm using COM8 on BILS CH39 its not a problem. So I guess EM COM8 is still there but I'm not in a position to see TV pictures from it. I'll get back to you on this but for the moment I'm more than happy with my two aerial solution.

Hi John,
Apart from LCN56 the other missing LCNs you listed are COM7 ;)
I don't know how your box works, but depending on the order you went through the UHF channels, you might find the "duplicates" up in the 800s.
Don't forget that there's a good chance you'll lose COM8 from Bilsdale on the 13th when it moves to UHF56 according to the predicted reception, and COM7 moving to 55 is predicted to get flakey.

Since 23 Oct we have been unable to retune to BBC4 HD on either Panasonic TV or recorder9both recent and worked fine until recent change.
As we use BBC4 HD a lot having to use SD version seems like a big step back
Any advice or are we stuck with it ?
Many thanks
