We're in Otford, post code TN14 5RW. The Otford transmitter gives a good signal but on a limited Freeview channel selection. I'd like to try Crystal Palace and/or Tunbridge Wells transmitters - can you give me the compass direction I need to use for these sources? Thank you.

Apologies - I should have said that we have a loft aerial. Also I hit the submit button twice! Doh...

Problem with Film 4 on 791, I do not get a program since doing the retune from 15.
I have even tried a manual retune but still no luck.

John: Film4 (15) recently moved to the PSB2 mux as used by ITV1, 791 being from its original COM6 mux although selecting it may result in a blank screen, you should carry out a "first time installation" in order to solve the problem, this also known as "factory reset" / "default setting" or some other similar term.

We have experience picture break up and freezing ever since we went to digital. This occurs mainly in the evening and early mornings and was also mainly on the BBC TV channels. This led me to contact the BBC and ask what was wrong. They came back with a load of gumff that really did not help!!. Our aerial and booster was fitted only about 6/7 years ago but I contacted a local aerial supplier who said they would come and look at it. We live on the top of Box Hill in Surrey and suffer atmospheric problems and winds so I thought this would be a good idea. The chap came and said that although we had a GOOD signal and as we were thinking of getting a smart TV instead of our freeview TV it might be an idea to update, which we did last week. The signal is as bad as before and I am getting to the point where I could throw the TV through the window as it always seems to break up at a vital point of a programme!!!. I called the TV aerial people and although they are coming back tommorrow to have another look the young lady did point out that signal strengh could be diminished by extra use in the mornings and evenings!!. If this is the case surely something can be done at Crystal Palace to improve this as I have found out a lot of my neighbours are having the same problem!!!. Can you please tell me WHY someone thought going digital would make ordinary TV viewers lives better as it does not!!. I do not want to have SKY or any such like as I think the costs are extortinate and I think the TV licence is enough to pay!! All I want is to be able to watch the TV with NO freezing or picture break up!!. Please please look at the signal strength and improve it as living the rest of my years on BOX Hill with no proper TV is very frustrating.

Mrs Julia Quinn: Unfortunately you havn't included a postcode, which would really help. However, a postcode put in the Digital UK website shows your about 26km from Crystal Palace, which is a powerful transmitter, and your on a hill. Its hardly surprising that the aerial chap said you have a good signal!
Almost certainly thats the problem - your signal is too good. You've got a relatively recent aerial, and somebody thought you needed a booster as well. If the signal is too powerful, then the TV's tuners just gets overloaded, and thus your picture breaks up. Its possible that during the time when you got a better signal, that the signal you were getting had just fallen enough for your TV to cope.
Try bypassing your booster, and see if it helps - hopefully thats all your should need (and save yourself the cost of getting someone to come out and have a look). Obviously, if the booster is on the aerial itself, then a professional will have to deal with it.

I'm not sure what the lady from the 'TV aerial people' was talking about, and I'm not sure she did either!

The lady at your aerial people doesn't know anything about how the system works! It makes no difference how many people are using the services from any transmitter, the signal strength is not affected by the numbers using it! The signal is radiated all round the aerial of all main transmitters like Crystal Palace and almost everyone in the London area who are not in a valley or shielded by a large building will get a signal. It is often the case that people on the top of a hill, like Box Hill, Reigate Hill or Tandridge Hill will get quite good signal strength - and that could be too strong rather than too weak. (My work area included Warlingham before I moved north.)
Are you sure you have a booster? Many homes these days use a distribution box that sends several signals to different places around the home. Some have a boosting effect and some do not. The box would look something like the one shown at
8 x Aerial Distribution Amplifier : Aerial Amplifiers & Distribution : Maplin Electronics
if it is a distribution unit, but more like the one at
1-Way Aerial Amplifier : Aerial Amplifiers & Distribution : Maplin Electronics
if it is only a booster indoors (outdoor ones are protected from the weather by more complex casings). These images are for illustration and each maker has different designs.
