Hi Mike,
Further to my question a couple of days ago (when I thought I was using Emley Moor), I have worked out that I'm receiving my signal from the Sheffield transmitter. My aerial is vertical but I'm only receiving PSB 1 and 2.
Signal strength is still very strong. You've been very helpful so far, thanks

Simon: Did you have digital before switchover started? Did you get Channel 5 analogue clearly?
If the answer to either of those was 'no', you may still have a Group A aerial, which was all that was needed for the four main analogue channels. It's sufficient for the PSB multiplexes, but for the commercial multiplexes, you need a wideband aerial. You would have needed a wideband for pre-switchover digital signals, and for Channel 5. See 'All about aerials' for information on the groups.
A Group A aerial should have a red plastic cap on the end of the aerial boom; a wideband would be black. It may not be very easy to see this, though. If the aerial is more than 15 years old it's likely to be Group A.
People *very* close to the transmitter might still get enough signal in the B-group channels to be usable even with a Group A aerial.

Hi there,
I wonder if anyone can help. I recently moved house in the S10 Crookes area. I've literally moved 3 streets away from my old house. In my old house I got all HD channels fine. I then moved house and got HD channels for about 5 days until the end of July when one night it just said "no signal" on all of the HD channels. I suspected it to be caused by the messing around with the transmitter so I retuned and then lost all trace of the HD channels. I thought we'd probably get them back after all the work on the transmitter was completed and the switchover was complete but we still can't get any HD channels today.
I have a new (4 month old) LG 37 inch Full HD LED tv. The aerial is in the loft and it's a rented house so I can't really go up there and fiddle about.
I've tried searching to see if anyone else has had the same problem but no one appears to have said anything on any of the forums (that I can find).
I can pretty much see the transmitter from my house so I don't understand why I can't get the HD channels and after an expensive move I can't really afford to pay for any engineers to come out so any advice would be most appreciated.
Many thanks.

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.
