Neil: Although I fully appreciate that your reception has prior to recent times been OK but that's the misleading thing about digital reception, insomuch that provided a signal is not suffering from rapid fluctuations in quality the picture will appear exactly the same from being received at a high strength right down to just before the lower cut off threshold, and so its possible that your signal could have been dropping in level over a period of time but is only now being noticed because its encroaching on your receivers lower cut off point.
If your aerial had been in the loft then I would have been inclined to suggest that you try moving the aerial a few feet to the left or right of it present position, as in non line-of-sight situations where a signal is being received via an element of diffraction this type of action can sometimes bring results by re-capturing the signal, because in areas such as yours if a person moved along a rooftop from one end to the other carrying a test aerial coupled into a signal meter, its not uncommon to observe the signal rise and fall in a ripple fashion from one end of roof to the other, not of course that it really helps an aerial installer to know this when a really good spot does not correspond to a chimney breast, although this being where gutter mounting is usually OK.
Another thing about reception under these circumstances being that picture glitching etc is always worse if a high gain aerial is used, because a high gain aerial is only that because the elements towards the front of the aerial called directors focuses the signal onto the aerials active element positioned immediately in front of the reflector, but when a signal is being received via diffraction the angle its being received at is not constant and can vary slightly to either side of the centre line that the aerial has been aligned on thereby defocusing the aerial, and so what's a director element one minute turns into an obstruction the next by partially blocking the signal path to the active element.
It would be interesting though to know the result if you cared to make a local enquiry regarding reception from some other household whose aerial is facing the same direction as your own.

Thanks for the explanation about 29th May.
I actually had not done what I only now see the site suggested and all our problems have been solved by retuning with the aerial disconnected, then retuning after reconnecting. We now have all the channels!

Agreed something must have changed, but I really don't know what it could be.
I tried asking one neighbour, but he was unaware you could get 'normal' (i.e. aerial) TV since digital switchover.
I only just realised that jb38's first post had some links to the right, pages I hadn't seen before on ukfreetv. Is this where you got your "obstructed" info from? The house icon seems the cover the terrain view in the closest 2 miles, so I wasn't quite sure if Hannington looked better or not. Realistically I would be pointing at a house somewhere further up the hill. Yes it is a high gain aerial.
I will see if I can ask some other neighbours at some point, or think about getting someone to see if any of the other directions are better.
Many thanks.

Neil: These are the links to the updated info showing the terrain between the three stations in question and your location when using the info you have now provided rather than an approximate test code.
Please note that the indications seen are purely with reference to the ground level and do not take into account trees or anything man made, these always making matters worse.

Neil: Just noticed that the link indicating the terrain between Crystal Palace and your updated location is defective and so this is a replacement.

I noticed this week that ITV1 carries Meridian News ( South ), while ITV1+1 carries Central West News. This gives us a choice of nearby regions, which is useful.
If I recall correctly, not long ago ITV1+1 carried Meridian News ( South East ). News and weather for Kent and Sussex were not very useful.

Oh dear! what has happened to Freeview again?
We have just got over the biggest retune in history and now channel 15 is telling me to do it again. Are they all totally incompetent?

In reply to the question about the impending loss of Film 4 on channel 15, you can see from the list at the start of the page that it has moved to PSB2.
Manually retune C60 and C55 to get back Film 4 on 15 and a bonus of Film 4+1 too on 45.

I can understand why people get annoyed over re-tuning... but surely by now freeview,tv's or boxes should be able to re tune themselves.. but thats not allways a good idea.. I have a goodmans box that BBC gave me for free due to my deafness. It has a habit retuning London TV which is very poor due to New reading train station building having alot of metal work round it!. so am stuck with Oxford... signal is ok but like anytime it has its ups and downs.
