Bennett: This is site independent of broadcasters where volunteers offer advice. It is intended for those who wish to sort out any issues they may have.
We would prefer it if people who only wish to moan and shout would refrain from posting.

Caroline Hewitt: The format for analogue (possibly "country" setting) is incorrect. It will need setting the same as that of the Sky box (assuming that it has such a setting.
I believe that the UK used PAL-I.

ji: If it is a single aerial that feeds the three TVs then how does the feed (from the aerial) split?
If it's a powered amplifier (booster) then perhaps it has failed. The fact that its light is on doesn't necessarily mean that it is functioning correctly.
Yes, you can use a Freeview box on a non-Freeview TV. If the TV has a scart socket then connect it using scart. If it's older and doesn't have a scaty socket then you may need something else to connect it.

Kelvin Wilson: If the loft aerial is a Group C/D one - with a green tip - then it might require replacement:
Aerials, TV Aerial and Digital Aerial
Or perhaps it is in a dead spot for C39 and requires moving.

Jim Millard: Assuming that you are using the Huntshaw Cross transmitter then its BBC standard definition services changed channel overnight. A retune is required to restore them. See:

Peter Hedges: I suggest that the reason for your difficulty, and the reason that Digital UK suggests such poor reception of the COMs from Sutton Coldfield, as against its PSBs, is down to the fact that Hannington's PSBs are co-channel.
The channels allocated to the COMs result in inferior coverage to the PSBs because they are re-used by other transmitters within closer proximity.
If you can move your aerial you may find that you can reduce the level of interference (without one of the other channels being affected). That said, you don't know how seasonal changes might affect reception. Or perhaps your aerial can be mounted somewhere where Sutton Coldfield's reception is good, but where the signal from Hannington is block, such as by fitting it on one side of your building.

Peter Hedges: I think that the reason for that it has been suggested that you can't have a mixture of channels from different transmitters is down to EPG data and particularly the starting of timed recordings where they are linked to the EPG (so that the recorder starts when the programme starts).
The EPG data for all services are carried by all multiplexes from any one transmitter. So, for example, the EPG data for BBC One is carried by all multiplexes.
Different transmitters can be of differing regions and therefore may carry different EPG data.
I write here as a technical-bod and not a professional, so this is where my understanding is a bit woolly. Personally I would be trying it out to see if it works!
Oxford carries different BBC and ITV regions. I don't know whether the EPG data carried by Sutton Coldfield and Oxford are the same. Perhaps it (using two transmitters) is only likely to be an issue when recording regional programming. I would be interested to find out what the answer is and reasons behind it.
In any case you may not be able to combine the feed from Oxford and Sutton Coldfield and receive all channels because COM4 from Oxford is moving to C50 on Wednesday. If a C51 diplexer is used to combine feeds then COM4 will fall below that and hence be picked up by the Sutton Coldfield-facing aerial.
That said, if it is only Sutton Coldfield's COM5 that you are having difficulty with then COM5 from Oxford won't be affected by the change on Wednesday.

Peter Hedges: I now see that you have your loft aerial pointing to Sutton Coldfield, but are managing to receive COM5 from Oxford with it.
Perhaps then, the answer is to look at relocating it in the loft so as to reduce the level of unwanted signal from Hannington.
Hannington is at 154 degrees, so consider where may be better screened from it, but which will get a good signal from Sutton Coldfield.

jb38: I'm not sure which "DUK trade predictor" you've been checking, but the official one suggestions diddly squat:
