Dave: tried that but ch49 doesn't seem to have any life in it. v.low signal strength reading (about 20%) and nothing at all in the signal quality.

Stuart: Where abouts are you? Perhaps there is another transmitter on C49 that is interfering.

Tony Ellis: Have you lost these channels following a retune today? Or have you lost them because you've moved to this address?
If your communal aerial points to Mendip then try a manual tune on C48 for 5*, 5USA etc and C52 for Film4 etc.

Stuart: Another transmitter isn't a possibility in Devizes. Not sure what else to suggest other than to check that there isn't another device inline with the aerial lead that is on C49 or nearby, e.g. Sky box, PlayStation etc.

I receive from the Mendip mast. This evening I have tried to retune BBC A to C49 but no channels are found. I have lost BBC1,2,3 and 4. I have followed all manual tuning instructions, is C49 more difficult to receive than the old C61?

@Dave Lindsay: we lost those channels sometime during the several retunes we've had to do over the past 2 weeks since this business started. I naively assumed we'd get them back today.
Tried the manual tunes you suggested but couldn't find anything - thanks anyway. Would still like to know what has actually gone wrong.

Tony Ellis: Refer to this list of services by multiplex:
DTG :: DTT Services by Multiplex
The Public Service (PSB) channels broadcast from all transmitters that former analogue did, hence it has the same coverage. The Commercial (COM) channels, which are those you're not getting, only broadcast from the largest, by viewer population, transmitters.
Bath has its own relay which is PSB-only. Thus, anyone who uses it won't have the COMs. In some cases it may be possible to use Mendip instead, so as to receive PSBs+COMs.
The only thing I can but wonder is if your aerial faces the Bath relay, which is next to Bath Golf Club. Even thought it's vertical and pointing in the other direction, you were lucky and managed to pick up Mendip's COMs.
If so then maybe you need to pester your landlord, or whoever's responsible for the aerial system, to get them to change it to receive from Mendip.
Bring up the signal strength screen on BBC One. For Bath relay it will be tuned to C25 and C49 for Mendip. And for ITV it will be C28 for Bath and C54 for Mendip.
One final question: What are the retunes that you've had to do? Choose which transmitter you're using there haven't been any retunes until today.

John Crabb: Shouldn't be. If you're using a communal aerial then maybe it needs adjustment so as to let through the new channel.
