Thanks for the reply, JB38.
Then in that case this new digital system is flawed. The TV is totally unwatchable in these weather conditions. Back when it was analoge you could at least watch TV, even with a bad picture.

Matt: The weather conditions would have exactly the same effect, be it analogue or digital. When I was growing up on the South Coast, such conditions used to mean French TV, rather than Southern. In fact, thanks to digital, that no longer happens.
JB38: Are you getting the same problem? I'm on Waltham, so I can't check (although that might explain the Pop TV signal falloff), but it would be useful to see where the problem is actually happening.

I live in Peterborough and have been losing TV signal for periods of 50 to mins at a time. Previous to tonight we had no such problems.

It did, Mike? I'm in my 30's. Growing up i can remember either having a good picture, a weak but watchable picture, and even sometimes 2 channels ghosting into one another. But it was always watchable regardless. Even with a wire coat hanger jammed into the back of the TV as an aerial. lol Everyone here seems to say the same as me.
Neighbours are having the same problem btw. We both just did another re-tune and lost loads of stations. The ones that remain are patchy.
We never had this fannying around with analouge did we. No having to constantly check connections, climbing up in the loft, having to come online to find out what the problem is etc etc etc. Back in the days of analouge if the picture was a tad crap you would simply twiddle the aerial on the back of the TV until you got a watchable picture. Happy days! =)

Matt: Yes, quite so, as analogue reception was far more robust as far as coping with interference is concerned, albeit that double images /ghosting, or images sweeping across the screen in the back ground were commonly experienced during high pressure related problems, digital signals unfortunately not being near so tolerant, picture break up or even vanishing on experiencing relatively low levels of interference.

MikeB : Sorry for the delay in replying. Yes, the situation is still the same when tested a few minutes ago, great signal but accompanied by zero quality. C31 still OK though!
Reception of Mux 26 (Pop) is not really possible in my area, at least not in an even remotely reliable fashion.
Of course PSB3 HD reception also vanished for a few hours on Sunday, returning later on in early evening, but though hopefully this issue will have cleared up by Wednesday.

MikeB : Well, even if I could receive Mux26, there is no danger of that happening, as anything remotely suggestive of a musical(?) assault on the ears, or alternatively orientated along the lines of sport of any description, automatically triggers the "change channel" or "off" button on the TV in my household.

Matt: Had the same at NN29. Panny TV. Funnily enough, without touching anything, back to 10 for strength and quality today. Interestingly though, my aerial goes through a BT Vision box first and had no problems watching that. However with quality back to 10 this afternoon I suspect a weak signal had something to do with it.

Our stations came back early hours this morning. I did a retune of the 2 main tv's and 2 set top boxes. 2 of the TV's and 1 of the set top boxes picked up every single station going. I think all from the same transmitter? BBC1 is on channel 1, BBC1HD is 101. TV's all say Cambridge and Bedordshire as the area. Arieal pointed to Sandy Heath. But oddly, the second set top box only picked up some stations and was missing BBC1 and BBC1 HD altogether. So i did a second retune of that box and it now has all stations the same as rest. Odd!
