This is the Now90's page. If you posted on the Emley Moor transmitter page you would have seen from recent posts that C36 is now used by the Emley Moor transmitter.
Emley's Multiplexes & UHF channels are now as follows, in the order -
PSBs1/BBCA, PSB2/D3&4, PSB3/BBCB HD, COM4/SDN, COM5/ArqA, COM6/ArqB, COM7 HD, COM8 HD, & Local
C47, C44, C41, C33, C36, C48, C55, C56, & C39.
You need to retune your Magic Eye on your Sky Box. AFAIK this is what you need to do -
Press the 'services' button the Sky remote
Select 'system setup'
Press 0, 1 & Select' in quick succession
From the Installer menu select RF Outputs'
Turn the RF output setting to ON' and exit saving settings
Also you can adjust the RF channel on which the Sky signal will be broadcast
If you are combining an aerial input into the RF output this is critical
If the RF frequency is already being using by a TV channel it will cause interference
Avoid this by selecting an alternative channel number from 21-69 (68 is the default)
Select RF Outputs'
Exit out all the way and check to see does the Sky eye now work
The LED on your Sky eye should now be lighting up
I would select the default C68, well away from any broadcast channels used by Emley Moor.

That should read: Press 0 then 1 & Select buttons in quick succession.
The question marks should not be there.

This is an independent help site for people with reception problems and has nothing to do with the Broadcasters or Freeview and the Transmitter operators. FYI it's not a case of "restriction", it's simply that the Commercial Operators don't find it cost effective to broadcast from "Light" transmitters because of the relatively small audiences served by them.
I'd suggest you contact Radio Times and other Programme Magazines directly.

I have already referred him to a full list of Emley Moor's channels in my post on p217 at 7.48pm on the 5th November which I might add was in response to you. Perhaps you missed it - again?

Sky News is on the ArqA multiplex see Channel listings | Freeview
Without a full postcode we can't tell what the predicted reception is likely to be at your mother's postcode and which transmitter(s) she might be receiving (several retuned on the 5th).
In the meantime, she could try unplugging the aerial and doing an automatic retune which should clear all previous tuning as no channels will be found. Then plug the aerial back and repeat the automatic retune and hopefully all channels will be restored.
If there are still problems, post back with further detail.

So how's your reception been going? There was some tropospheric propagation several days ago which may have disrupted your reception at the time, but things should now be back to normal.
So what's the news on the filter?
So where did this Dion box come from?
I'm not sure where you multiplex "identification" is coming from, but some of them are not as the list I've posted. Upstairs (all appear to be Bilsdale) you appear to be missing PSB3 (HD) - C27, yet you have COMs 7&8 (HD) C55 & C56 but you have the IDs mixed up with the Local mux on C30.
Downstairs apart from PSBs 1 & 2 (from Bilsdale), you have COMs 4-6 & Local from Emley! but you have the IDs mixed up, COMs 4-6 are C33, C36, C48 and the Local is C39.
So you appear to have quite a strong signal there from Emley and must be picking it up on one of the aerial responses side-lobes!

The Horror Channel is on the SDN/COM4 multiplex see Channel listings | Freeview which you might find useful.
C42 is indeed COM4 from Sheffield, but C33 is COM4 from Emley Moor so it looks as though you may need to manual tune rather than auto tune.
Your aerial(s) are probably picking up the signal on a reception side-lobe & even the polarisation may have changed somewhere on the propagation path depending on if there's been any reflections etc. This would also explain the lower signal strength and also that the signal may drop-out periodically, hence the pixelation.
I'd suggest that on the sets/devices where you have the issue that you unplug the aerial and do an automatic retune which should clear all previous tuning as no channels will be found, and then plug the aerial back in and do a manual tune. Sheffield muxes are on C21 - HD, C24 - PSB2, C27 - PSB1, C39 - COM6, C42 - COM4, & C45 - COM5. There is a Local mux on C35 which you may or may not be able to receive.

Richard caywood:
Whilst that is true, about no "shielding" most electrical interference actually travels up the cable to the affected equipment, there isn't that much "radiation" from most cables. There will be some, but because most cables have the L & N in them, they are "balanced" because the current going down the neutral is the same as the current coming up the live, so cancelling each other out from a radiation point of view. The recommendation is to try and not have other "signal" cables running parallel to mains cable and ideally more than 6 inches away from them.
Personally I don't think your issues are "electrical" interference as such. It does seem to be a problem that seems twofold, one to do with mobile interference from stuff that is operating in the 800MHz band (ie. above Channel 60). I think the other part of the problem is just simply signal overload - too much signal (whether it be received DTV signal or mobile is difficult to be sure), but the question as to why this happened as a result of the re-wire remains unsolved at present.
A thought did occur to me a while back, but I didn't want to complicate the picture at the time. You said your aerial is mounted on a pole which is wall mounted. When they re-wired, did they by any chance fix an earth bonding wire to the base of the pole?
Gong back to the DTV your are picking up, it's not the UHF channels that I query, it's the name given to them ie. downstairs you say eg. you have coms 4 uhf ch36 & coms 5 uhf ch33 when they are the other way about - ch33 is com4 and ch36 is com5.
Also coms 6/7 uhf ch48 and coms 8 uhf ch 39 when com6 is ch48, com7 is ch55, com8 is ch56 and ch.39 is a Local mux.

Doug:
I assume your aerial is pointing at Emley Moor from which you should get very good reception of all multiplexes which means you should get 145 TV and Radio channels (if your set has an HD tuner, ~113 without HD).
I hope you are aware that there was a "retune event" recently for Emley Moor (the last of the currently planned multiplex moves to different UHF channels).
Emley's Multiplexes & UHF channels are now as follows, in the order -
PSBs1/BBCA, PSB2/D3&4, PSB3/BBCB HD, COM4/SDN, COM5/ArqA, COM6/ArqB, COM7 HD, COM8 HD, & Local
C47, C44, C41, C33, C36, C48, C55, C56, & C39.
I'd suggest you unplug the aerial and do an automatic retune which should clear all current tuning as no channels will be found. Plug the aerial back in and repeat the retune, hopefully all your channels should be restored.
If you are still missing channels, it could be that you have an old grouped aerial rather than a Group T /Wideband. Then you should ring the Freeview Helpline on 0808-100-0288 where they should offer to organise a replacement aerial free of charge if you don't have Satellite or Cable.
