The symbol shows the location of the Emley Moor (Kirklees, England) transmitter which serves 1,550,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

When ITV1 analogue went off-air, but before PSB1 started up, I could see a very fuzzy BBC1 analogue signal on that frequency. This is strange because according to this site, none of the other in-range transmitters are broadcasting BBC1 on C47.
I also thought it would cause interference issues with the MUX coming on that channel, but it hasn't. Now I can't pick up the fuzzy BBC1 any more, but PSB1 has maximum signal strength and quality.

Thomas: I agree that it's not likely to be another transmitter, C47 wasn't often used for BBC One, the map at UK TV Frequency map - channel C47 (682.0MHz) before switchover map | ukfree.tv - independent free digital TV advice shows only Holywell, near Liverpool, and The Bournes, south of Aldershot. Both are very low-power relays on vertical polarization.
The transmitters are not perfect and do produce some intermodulation products outside the allocated channel. The out-of-channel emissions are filtered off within the channel combining unit, but these filters are only as good as they need to be to stop too much interference being broadcast or power being fed back into another transmitter. If you're close enough, you certainly could have been watching a little intermodulation.
The digital transmitter manufacturer claims that out-of-channel output should be less than 40 dB below peak level (or 0.01% of peak power). Arqiva's filter specification is an additional 18 dB (1.6%) in the adjacent channel, 43 dB two channels away.
Sources: http://www.actuonda.com/p….pdf p20, http://www.arqiva.com/cor….pdf p23.
You can see what 44 dB less signal gets you at Comparison of signal quality with reducing signal level - the bottom picture is 44 dB lower than the top. There's still a degree of colour in there, and given your location I suspect your analogue levels are over 60 dBuV already.
Digital only requires about 20 dB of signal-to-noise ratio to receive reliably, so I don't think this interference generated within the transmitter itself is likely to be a significant problem - certainly if you never noticed it on analogue.

Ref my previous comments (5th from top of this page)and the two comments following from Hacker and David, Channels C22 C25 and C28 are indeed from Belmont, however you dont have to pick them up.
It is essential that you first remove all existing multiplexes on your Set Top Box or Dtv. There are several ways of doing this but the easiest is to return your Set Top Box or Dtv to `Default or Shipping Condition` in the menu, via Installation or Set Up (It depends on the make and model of equipment you are using)
When you have completed this the Set Top Box or Dtv may start on Automatic Tune Up, you must stop this very quickly otherwise (from channel 21) programmes will start to load up and you will be back where you started from.
You will then need to select Manual Search from the Installation Menu or Tuning Menu and then enter and save each of the multiplexes that you require in Yorkshire (list as my earlier comment).
Please note that entering multiplex channel numbers will not override any channels already tuned in.
A bit of a pain I know but if you only want signals from Emley Moor, but are picking up channels from other transmitters the above info should help (It will also get rid of Peter Levy !!!!).

After retuning I've got all the BBC digital channels but back on analogue I can no longer get Teletext, hence no 888 subtitles. Is this intentional?

David Mansell: Yes, the teletext system no longer in use, use the digital subtitles service.

Anyone know what's happened to digi C46 (Challenge?)
I retuned for BEEB this am and noticed 46 was showing no signal, but its not in the Mux A list (C43) any more

And it's great fun trying to explain what a mux is over the phone to someone who's only bothered about not missing this morning's Homes Under The Hammer. :)

Just wondering, could we not have a frequency list for...

For some reason I cannot get any of the BBC Red Button services to work on my Freeview tv, even though there's a Freeview tv downstairs whose Red Button services are working fine. There's nothing wrong with the remote; the batteries are fine, and the buttons are ok. I just cannot get the Red Button services to appear. The 'Press Red' icon on BBC News no longer appears; the BBC radio channels are also without any interactive services (they play but just appear black with no screen info). I've also noticed that other interactive services on other channels including ITV and Channel4 no longer work, either.
I'm in Nottingham, and I've rescanned 3 times, finding 161 services (including loads of weird duplicates). None of which, apparently, are interactive. Am I going crazy, or is this deliberate and part of the switch-over? How do I get those services back?
