Robert: It is so as to save the cost of producing more streams that differ for each region. See:
ITV1+1, ITV1HD, BBC One HD regional services on Freeview | ukfree.tv - 10 years of independent, free digital TV advice
For the same reason the BBC only has one variant of BBC One HD and regional news programmes don't yet appear on it.

Anne: At the first stage of switchover (this happens everywhere), BBC Two analogue is switched off and the new full-power BBC digital multiplex (signal) comes on air. This multiplex carries BBC standard definition TV and radio stations (BBC One, BBC Two, BBC Three, BBC Four, BBC News etc).
For relay transmitters such as Aislaby which have never carried Freeview before, this means that they continue to broadcast BBC One, ITV1 and Channel 4 in analogue and BBC standard definition in digital for the intervening period. This means that ITV1 and Channel 4 can only be viewed via analogue and BBC Two can only be viewed via digital (Freeview). BBC One is available on both.
For those who are receiving from a main transmitter (such as Bilsdale) that carried Freeview before switchover, but who were too far away for the weak pre-switchover signals to reach, they are in the same position (as above) for the two weeks.
The reason for this staggered approach is so as to give those who haven't bought a digital receiver, or who have and which is not compatible with the post-switchover signals, the opportunity to buy one. It also means that they will loose access to only BBC Two.
As your aerial is directed to Aislaby, then the manual tuning won't do any good because what I suggested above assumed that you were receiving from Bilsdale.
Perhaps you will have to get the piano this evening!
One last warning: The Aislaby transmitter will be Freeview Lite which means that it will carry only Public Service channels. These are BBC standard definition and high definition, BBC radio, ITV1, ITV1+1, ITV1HD, ITV2, Channel 4, Channel 4+1, Channel 4HD, E4, More4 and Channel 5.
The Commercial channels that include ITV3, Film4, Dave and others only wish to broadcast from the main transmitters because they are more lucrative for them. This is because they give them the greatest number of viewers for lowest cost.

Anne: On 26th September Aislaby is not expected to be back on until mid-afternoon.
Keep a note of this link to the Digital UK site:
Digital UK - Relay transmitter switching times
It lists when each transmitter is expected to be up and running and is updated during the day so as to show when each one has been done.

Anne: Happy to help.
If the new TVs have analogue built-in, then you may be able to tune them in for ITV1 and Channel 4, giving suitable instructions to your guests on how to switch between analogue and digital.
Or you could leave them the old and the television each...
I guess that this has cost you to replace them all which isn't what you need.
All the best and let us know if you have any more questions.

Lesley: I presume that this is a VCR that receives analogue signals only as you mention the loss of BBC Two whose analogue signal was switched off. In which case you should be aware that the analogue signals of BBC One, ITV1, Channel 4 and Channel 5 (if applicable) will be turned off on 26th September.

Jack Detsios: See this page:
The Great British Paraorchestra
- The Great British Paraorchestra - Channel 4
It is next broadcast tonight at 6pm on 4seven if you can receive it.
Unfortunately it is not available on 4od.

Peter Coyle: Check that the Hitachi is tuned correctly, to Pontop Pike for BBC on UHF channel 58. Do this by viewing the signal strength screen.
It is possible that it has decided to go with the signal from another transmitter. Overlap is much more a possibility now that the BBC digital signals are on full power.
If it turns out that it has gone with another transmitter, then a workaround may be to unplug the aerial for the first part of the scan. It depends on whereabouts within the UHF channels that it has tuned to (they run 21 to 69).
From 26th September, Pontop Pike's lowest will be C49, so have the aerial in for that. Get the aerial in for 55% should do it. This will work if the signal that you're trying to avoid is much below C47.

Brian Wegg: The photographs of your road shown by Google Streetview are dated August 2009 and show what could be construction works in the field on the opposite side of the road. The satellite images are presumably more recent as they show three buildings in that field.
As these could be in line with the transmitter I wonder if some change there could be the cause. Have you noticed any changes in the area, particularly in the line between you and the transmitter?
