Kathryn: Without knowing the full post code its a bit difficult to assess where you are receiving your signal from, as indications are that you can get first class reception from either Emley Moor or your local Sheffield transmitter, the latter showing "0" distance on an S10 code, but whether or not that is where you are receiving your signal from isn't for certain.
To check on this, if you carry out a signal check on BBC1 Emley would be Mux Ch52 with its HD Mux being on Ch39, whereas Sheffield BBC1 is Mux Ch27 and its HD Mux being Ch21.
If you hadn't have previously had HD reception I would have been suspicious about the capabilities of your TV, but if its manual states in the tuner spec section DVB-T2 capable, then that can be excluded.
The other great possibility is that the signal is too strong, so "if" you have a set top aerial around carry out a re-tune with that temporarily installed, of course trying it out beforehand to make sure you can actually get BBC1 / ITV etc using it, if HD is received via the set top then you will have to purchase a simple attenuator to place in line with your aerial socket.

Kathryn: if you got HD channels before the 24th of August, you got them from Emley Moor, not the Sheffield transmitter. If the new house has an aerial pointing at Sheffield - with elements going up-and-down rather than side-to-side - then you were lucky to get the HD channels at all, as the aerial is designed to reject signals from the other polarization and from a different direction.
The Sheffield relay transmitter exists because Emley Moor doesn't cover the city fully. Check what your neighbours are using, or wait for the Emley Moor switchover to complete on the 21st of September.

Kathryn: Just a further bit of info regarding your reception. It seems to be that the further along Crookes you travel the better the reception gets, as a test code of S10 1UA (15 Crookes) gave Emley reception as only being possible on three Mux channels, whereas moving upwards along Crookes through codes of 1UD (181 Crookes) showed 4 Mux channels as good with two zero, then from 214 - 257 Crookes (codes 1TG / 1TE and 1TF) revealed perfect reception being indicated from all six multiplex channels.
So as you will see what you receive very much depends on where you are located within relatively short distances, although no matter where it might be reception is always indicated as being good from the Sheffield transmitter, so try a test using manual tuning on the Sheffield HD Mux channel mentioned, that being Ch21.
That said though, "if" your aerial has been set up for Emley then it will be pointing a little too much to the North at about 337 degrees, whereas using all of Crookes as a reference it should be from 208 / 247 degrees for Sheffield, so with the possibility of the direction angle being out coupled to the polarity (V /H)) being wrong then this would have a negative effect on your signal strength received from Sheffield, but one never knows at such as close range, as these errors have much less of an effect as such.
By the way Emley Moor HD on Mux Ch39 is on low power until September 21st, so even although it does show as being good (reasonably anyway) for reception on a number of test codes, I wouldn't really have too much faith in it.

Hi
Thank you all for such good information. I was just wondering myself today whether or not we were actually on Emley Moor transmitter as I can today still receive analogue channels. However, I did receive notices via the tv teletext thing saying I had to retune and these notices came up on both the 10th and 24th so I had assumed we were on the Sheffield transmitter.
I am not particularly technological so will need to dig out my tv manual to do a manual retune of the HD channels.
I will also try using an indoor aerial and see if that helps too and will report back asap!
I live in S10 1SS. Previously we were in S10 1RE. We received HD channels fine at S10 1RE and fine at S10 1SS for several days after we moved in, then we lost them around the 25th July.
I was wondering if it could be a problem with my HD freeview box (built into the TV), but then would I not receive any of the channels if that had a fault with it? Just to lose the HD channels seems a bit too selective for it to be a hardware fault but any advice in this regard would be most appreciated (the TV should still be under guarantee).
Many thanks for your help.

Kathryn: Just carried out a check using the post code you provided, indications being that of superior reception being possible to anything previous seen with any of the other codes, this being a good thing in one respect but problem causing in another if tuning using auto-tune, the reason for this being that Belmont now comes into the equation.
The problem is that auto-tuning always starts scanning from the bottom of the entire channel range, slowly travelling upwards locking onto each Mux channel found and storing the programmes from it, then once done travelling on to the next doing likewise on so on. Because you appear to be able to receive Sheffield, Emley Moor, Belmont and possibly two others, this means that when carrying out an auto-tune your TV is liable to store the odd Mux channel from anyone of these other stations if its Mux channel is strong enough for the box to lock onto, storing the stations from it rather than just keeping on the station that you require, being Sheffield.
Lots of people get this problem, although some sets have the option on their tuning menu of being able to select scanning a particular area, but this can be iffy in practice and not always as good as it might appear, so its always best to carry out manual tuning in these circumstances, starting with say BBC1 and using the add channels facility for each additional Mux Channel of the station required.
In your case Sheffield uses Mux Ch's 27 - 24 - 21 - 42 - 45 - 63.
As far as HD is concerned, you might well have possibly been receiving HD from Emley, but for some reason or another it dropped out for a short spell and you just haven't managed to recover it as yet during auto-tuning, possibly because of its lower power not proving enough signal for your TV to lock onto, especially "if" your aerial is pointing at Sheffield.
Anyway, if you see "Set up" on your menu that's where you will (or should) see the options for tuning, that said though, I am aware that some boxes do not allow manual tuning, but best try and find your user manual.
Maybe you could indicate the model number of TV you have.

Kathryn: Just a little addition, as HD was your main issue I would concentrate on trying manual tuning purely on the HD Mux channels, storing anything received.
This can be done without scrubbing anything already stored using the "add channels" facility in your tuning menu.
Sheffield HD - Mux Ch21 / Emley Moor HD - Mux Ch39 / Belmont HD - Mux Ch28.

Hello,
After a weekend playing about using your kind instructions I have found that my aerial is indeed set up to receive Emley moor - bbc channel was tuned in at ch 52. I honestly cannot fathom why someone would set it up to receive Emley Moor when I have a line of sight of the Sheffield transmitter but hey ho. Funnily enough when I checked my other tvs in the house which work via indoor aerials they too were receiving Emley Moor so we must just be lucky enough to receive good signal from all that way. That being said we get better signal strength now I've retuned them and repositioned the indoor aerials.
As for my HD tv that runs of the house aerial, I first tried to manually install the HD channels but it just kept saying no signal for both the Emley moor HD channels and the Sheffield transmitter HD channels. Following your advice I realised that it was likely my aerial is facing Emley moor and not Sheffield and that due to some sort of atmospheric/weather related miracle I got the HD channels before but now the aerial needs to be facing the Sheffield transmitter or I need to wait for the switchover at Emley Moor.
I tried a factory reset with the hope of erasing things from the tv's memory so it could then try to pick up the Sheffield transmitter but that didn't help.
After losing the bbc channels today (presumably due to the Emley moor transmitter having work done/weather or a combination of that and the fact I've been fiddling) I took an indoor aerial from the tv in my kitchen and faced that in the direction of the Sheffield transmitter, did an auto retune and hey presto, I've got the HD channels back and a lot more new channels too!
I suspect that when the changeover at Emley moor is complete we'll be able to receive the HD channels through the aerial on the house. Failing that I might have to go up into the loft and try to turn the aerial to face Sheffield. However, until then I am happy to have the channels back through the indoor aerial.
Many thanks to you both, JB38 and Mike, for all your advice, without which I wouldn't have been able to get to the bottom of the problem.
Kind regards
Kathryn

I live in Sheffield and we have had no problems with DSO on 10th and 24th August. I was not expecting any other changes, except for a retune on 24th September (not sure what that is for though).
However, our local news mentioned a DSO for Yorkshire last night which I hadn't heard about and didn't think would affect us. This morning I found no change to the BBCA mux on our main telly (roof aerial, humax PVR), but our bedroom telly (portable with 'loop' aerial, cheapy Philips STB) has lost the BBC channels on the beginning of the channel list, and I have since found them in the '800's part of the list, which did not work yesterday.
What does this mean? Should I start using the '800's on the main telly (I had deleted them from the channel list as they had seemed to be defunct)? Will this all change again when we're supposed to retune on 24th Sept?

nitty: You didn't provide a postcode, but you are probaly using the Emley Moor transmitter on the set that changed. See Switchover starts in 4 million homes in Yorkshire, West Midlands 7th September | ukfree.tv - independent free digital TV advice .

Thanks Briantist. My postcode is S11 7PD. I know the roof aerial is pointed at the Crosspool (relay??) transmitter. I have no idea where the portable aerial is aimed at as I don't know anything about how the little ring aerials receive signals - if I turn it a different way will it pick up from a different transmitter?
