Will: At Sandy Heath, ArqB's final channel allocation is C48 - sorry if that wasn't clear. ArqA's final allocation is C52, which can't be used until after Tacolneston Channel 5 shuts down on 23 November. C40 was the pre-switchover channel for Mux C, which could continue to be used until Sutton Coldfield DSO. The issue isn't really that Sandy Heath would interfere too much with Sutton Coldfield, but that SC would interfere with Sandy Heath.
Sandy Heath has been a nightmare, there will be a total of six retunes - the two DSO stages and four post-DSO retunes. It's an issue of geography and of coverage overlaps.
Sources of channel information: Television Transmitter Frequencies for analogue and low-power DTT, Ofcom | Digital Switchover Transmitter Details for final DSO channels, Ofcom | Supplementary licence documents in relation to DSO for interim updates from Ofcom. However, Ofcom seem to be following what the broadcasters decide (particularly Arqiva) rather than leading, and more up-to-date information is often available in Digital UK's Almanac
Transmitter Network - Digital UK Almanac and postcode checker Postcode Checker - Trade View . All these sources have inaccuracies and you have to use a bit of common sense to figure out what the true picture really is.

TO Briantist
Thank you for your advice regarding my above help needed...much appreciated your time and help!. I followed your link and did the instructions. I tried 3 times and still itv, ch4, ch5 etc came blank. So i tried a wide aerial and re-tunned following your instructions and it worked, all my channels are back on (So anyone who is having problem like me ..google wide aerial image get that..try that, it worked for me and the above instructions).
However, I have a new problem. When i turn my t.v off and freeview nothing is on display (it says ch1 etc all blank) so i have to re-tune again and they all come back on. Before with the old analogue t.v i could turn my tv and freeview box off to save electricity and when i put back on all my channels are there. Please help i do not want to keep re-tunning. Would this problem go away by the next date for swtich over in my area think it is 22nd september 2011. What shall i do? Thanks

debs: If using a set-top aerial worked when the roof-top aerial didn't, you have too much signal. Remove any boosters that you might have, and possibly add an attenuator. You *will* get best results from a roof-top aerial as long as the levels aren't overloading any equipment!
All transmissions from Emley Moor have always been within the original analogue aerial group, except for Mux D, although many Group B aerials will still work reasonably well up at C55, and you're close enough for it not to matter. A wideband isn't necessary after switchover completes on the 21st, as everything then will be within Group B.
Some older boxes did store the channel line-up in volatile memory - which requires power to maintain the contents - but most store it in Flash memory, which doesn't require any power. It's possible some might have used battery-backed memory and the battery is no longer any good. Without a full model number it's impossible to know. It may be easiest to just replace the box.

Thank you to Mark Fletcher. I had forgotten that some of the earlier production HD Ready TVs weren't clever enough to sort out the channel list and took virtually first come - first served irrespective of the signal quality. Thus I ended up with the BBC regional programmes being incorrectly channelised. My old Goodmans allows me to manually tune to delete channels and so I was able to remove all the data for signals received below channel 40 leaving me with the correct Yorkshire channels from Emley Moor. I do not however envy the Belmont-served people who have to change their aerials to cover the band. Thanks.

Re:Tony Riley.No problem at all.I am glad to be of assistance to yourself and anybody else come to that matter.I'm no professional myself,just an amateur,but i do have some knowledge on TV,aerial and reception issues.It will be interesting once switchover for Emley Moor is completed on Wednesday 21 September 2011 on how everything evolves thereafter.Finally as for Belmont yes equally interesting here as now to receive all 6 Mux's a Group W or "wideband" aerial is required yet according to A.T.V. (Aerials and Television) of Sheffield,looking through their website,widebands or Group W aerials,are quite useless when it comes to channels on the lower end of the frequency spectrum,especially the familiar Group A aerialed frequency Channels 21-37,in which 4 of 6 of Belmont's Mux's on channels 22,25,28,30 are within the Group A aerial range.The other 2 on channels 53 & 60 (currently both on 4kw until Wednesday 23 November 2011 when Tacolneston totally switches over,due to frequencies 53 & 60 there clashing with Belmont) fall within either Group C/D range,channels 48-68 or Group E range,channels 35-68.

Been to Norfolk Belmont high muxes are coming in very powerful, just at home in Yorkshire.
So if I were in Belmont area I would not rush out to buy a new aerial, I would wait and see how present aerial works when all at Belmont are full power.

Further to a posting four days ago thank you Briantist and jb38, my large external aerial feeding a loft booster/distribution system from Emley Moor feeds a large Sony ok but small Sharps and Hitachi have no channels. I have borrowed a desktop aerial and these sets now tune ok, I can confirm that the signal power to S26 6SR is too high to require a booster.

Hi,
We have BTVision. Since the switchover we have no channels at all, tried to re-programme (search) but says 'no signal' and 0 channels found. Can anyone help, we live in S75.

Mark Fletcher: 'Useless' is a bit strong. The CAI Standard 1 specification is 10 dBd minimum in Group A, 11 dBd in Group B, and 12 dBd in Group C/D. These are the figures used in the Digital UK postcode checker, which allows for 3 dB of cable loss in Group A, 4 dB in Group B and 5 dB in Group C/D for a net 7 dBd across the whole width.
Even the massive XB22WB doesn't manage this below C30, offering only 7.5 dBd at C21.
However, Standard 1 is intended for use only at the extreme edge of the coverage area. Standard 2, for use in medium signal areas, requires 7/8.5/10 dBd in the three groups for a wideband, a Group A or K aerial must offer 0.5 dB more in group A. The Log40 achieves this standard up to C64; although it doesn't quite manage it above that, that's probably a good thing considering C61-C68 are released for 4G phones!
The CAI also define Standard 3, which contract widebands can achieve as it only needs to deliver 5/7/8 dBd. Again, a Group A or K Standard 3 has to deliver more gain in Group A than a wideband, 6 dBd. Standard 4 is wideband-only and covers small logs delivering 7 dBd in all groups.
I would really expect anyone who actually needs a Standard 1 aerial to get Belmont would get better results from a different transmitter anyway!
