Adele Dodgson: I have located the instructions for your Philips box:

I haven't found out what the memory capacity is, so I think you will have to try it and see. I am wondering if duplicate programme channels aren't put in the 800s on your model, but perhaps in the 700s.
What I would do is clear the channel memory by running the scan without the aerial plugged in. You should then find that the Channel List is empty. If it's not then delete any remaining channels (or there might be an option for this).
Having done that, use Manual Search to tune in the five multiplexes from Tacolneston. These are BBC=Ch55, ITV1/C4 etc=Ch59, ITV3 etc=Ch42, Pick TV etc=Ch45, Yesterday etc=Ch50.
Do that and see what happens. If it forgets the last multiplex to be stored, then that I expect that it is going to be ArqB on Ch50.
You might have to compromise and loose one multiplex, or perhaps you could delete some programme channels that you aren't bothered about within some of the multiplexes to make space. As I say, I don't know for certain and personally I would experiment.

tony: You're having a laugh!
It doesn't carry FM and is only a low power TV relay. I should expect that if you're going to receive DAB, then it will be from elsewhere, in much the same way as BBC national FM comes from elsewhere.

Adele Dodgson: Good to hear that you have sorted it.
Is this other TV a really old one? By fuzzy noise I am wondering if you are referring to white noise. For the last couple of decades analogue TVs have muted the sound of such noise, so you must have an old TV.
When you put your hand next to the screen, can you feel static?

Bill Bullock: In order to answer the question, your location is needed or the transmitter from which you get your TV.
From the post code against one of your previous postings you are probably on Crystal Palace. The reason for retuning is for the switchover from analogue to digital.
The analogue signal for BBC Two will be switched off and ITV1 analogue will take its place (on that frequency). The full power digital BBC service will be broadcast on the same frequency as what ITV1 analogue used to use.
Two weeks later, the rest of the analogues will be switched and their vacant frequencies will be used for the post-switchover high power digital services.

Sue: The difference between Crystal Palace and Reigate signals (apart from, perhaps, the direction that they come from) is that the former are horizontally polarised and the latter are vertically polarised.
If your aerial is horizontal, then you are on Crystal Palace and if it is vertical then it is Reigate.
See here for a photograph of aerials in each polarisation:

There is no such thing as a "digital aerial", but in some cases a different aerial may be necessary, but that is due to different signal strengths or different frequencies being used than are/were used for analogue.

Jeff Meagor: The three commercial (COM) multiplexes from Beacon Hill are at half power with respect to the Public Service Broadcaster (PSB) ones, they are 10kW and 20kW respectively. The power of the PSBs is so as to provide the same coverage as the old analogue ones did. My point being that the COMs are restricted as opposed to the PSBs having extra strength. This could be to protect against interference with other transmitters using the same channels such as Plympton.
The other thing about Beacon Hill is that the UHF channels (frequencies) it used to use and those which it uses now. For analogue it was Group C/D (Ch48-68) only and if you haven't had the aerial changed from a C/D, then it could be the problem. Whilst the PSBs are C/D channels, the two COMs SDN and ArqA are a bit lower down in Group B (Ch35-53).
For information on aerial groups, see here:

Are the services that you are trouble with in the COM multiplexes which are on lower power? Are the BBC and ITV1/C4 ones OK?

Roger Evans: BBC Radio Wales and BBC Radio Cymru are available on Freeview in Wales on (logical) channel numbers 719 and 720 respectively.

You might be able to feed to sound from your Freeview box into your amplifier or speakers so that you can listen without the need to have the TV on.

Sue: Which transmitter will provide the best signal depends on the location. A post code is an extremely large area and results can vary greatly. Furthermore, the predictor does not take into account obstructions such as buildings and trees that will affect reception. It should be used as a guide only.
If you are having issues with reception; for example some channels break-up or disappear at times, then it must be borne in mind that in three months time the transmission power of Crystal Palace and Reigate will be increased (at switchover) and as such is likely to irradicate any issues with the signal going into your receiver being too low (or touch and go).
This means that any changes you make will probably only be needed for the next three months.

marez: Unless the TV works with Freesat, then you will need a Freesat set-top box.
If you post the make and model number of your set, we can have a look at the specifications and tell you whether it will work with Freesat. Most don't and are only designed to receive terrestrial signals without need for a separate box.

Becca: If you post your location (preferably post code) we can get an idea of what the likelihood of reception is.
