Sorry, I misunderstood; I thought this was an updated reply to your FoI request.

The link for "DAB transmitters, multiplexes and radio stations" doesn't seem to work at the moment.

Does anyone know if the signal attenuation to the East (to prevent interference on Guidford analogue) will cease after DSO? If so, what increase in signal level could be expected?

Nick: Most digital TVs also have an analogue tuner. You should check your TV's handbook for how to select it.
Alternatively you could use a 'video sender' which connects a wireless transmitter to the scart of your Sky box, and a receiver to your TV. This also carries the remote signal back to the Sky box so that you can change channel etc. remotely.

I have retuned this morning to find that the BBC A mux now has frequent break-up. The signal quality is significantly lower than before the move. I'm not sure if it is working on reduced power temporarily, or if we have to put up with this until stage 2 of the switchover or even until the power-up in April.

I am definitely on the correct mux (45) and I have tried a 9dB attenuator which took the signal level from 67 to 58 and the quality from 89 to 69. 45 isn't used by any nearby transmitters. I have no duplicate channels.
Unless my aerial has a frequency notch at ch.45 (unlikely as BBC2 analogue was OK before the switchover), I can't see any other explanation than that the transmitted power is reduced, at least in my direction (SE from Hannington).

Brian Jonson: There will be a significant increase in signal strength in April after the London switchover.
There should be smaller increases in signal strength at each stage of the Hannington switchover, but I'm not seeing it so far (see above).

Catherine, do you know whether you are receiving from Crystal Palace or from Guildford? If the elements of your aerial are horizontal, it's CP; if they're vertical, it's Guidford.
My guess is that your aerial is pointing at Guildford but you are picking up a weak signal from CP, which your receiver is finding first.
A factory reset and a manual scan should fix this.
