Kevin: I'm not particularly familiar with DAB myself, but I suspect that different multiplexes that serve any one location will often be from different transmitters. Whether that is the case where you are, you will have to check out.
Ofcom publishes the technical information on DAB (and FM/AM) transmission sites here:
Ofcom | Tech Parameters
There is the BBC national multiplex, the commercial national multiplex, a "Central Lancashire" one and one for the North West.
The document shows that these all have transmitters sited at Pendle Forest. There may be other co-sited transmitters for these services in Lancashire, I haven't checked.

Kevin: Here is the list of transmitters in North England on the commercial national multiplex's site:

The BBC has published a list for its national multiplex here:
BBC - Help receiving TV and radio - Transmitters
You should be able to sort the spreadsheet and come up with a list of possible sites near you.

Kevin: As you're in the Pennines I would certainly urge caution. If you're on the top of hill and can see for miles, then that's another matter!

Tony: Do you have a signal booster/amplifier fitted? And if so, try removing it?
What is the signal strength like?
Did you get digital TV ok before switchover? How was your analogue reception?
Looking at Google Streetview, it does look like the church could be in the way for some of the houses.

Bernard Peard: Perhaps you can clarify which TVs are connected to which aerials. What are the "silly channels" you make reference to? Do any TVs successfully tune into any channels (multiplexes) and if so, which? What is the signal strength on these multiplexes?

Keith: Have you established that the respective channels are tuned to UHF channel 55? Are you sure that it isn't the signal from another transmitter?
I guess that with 100 flats inside, the building you're in is pretty tall and therefore that the aerial is high up, which means it could be picking up signals from other transmitters.
I assume that your reference to "MuxD" is in fact Com6 which is Arqiva B. MuxD was used for one of the pre-switchover multiplexes.

Tim CO14: Definately don't use your booster!
I think that you need an attenuator. It's sounds like your receivers could be being blinded by the strong signal. Amplifying makes that worse.
Is the signal strength lower from the loft aerial? If so, then try connecting the other TV(s) to (that were served by the chimney aerial).

Adrian: Try carrying out this procedure:
My Freeview box has no EPG, is blank on FIVE, ITV3, ITV4, ITV2+1, has no sound or the channel line up is wrong | ukfree.tv - independent free digital TV advice
If that doesn't do the trick, try manually tuning. I found the instructions here:

Page 16 sets out the procedure. For BBC, search for 55.

David Male: Answer is no, your relay isn't likely to carry additional services:

Colin: What model TV and set-top box (if you have one) do you have?
What is your post code as it might help suggest a solution because then we can get an idea of what the signal is like in your area.
