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!

It has been suggested that the recent warm days have given rise to atmospheric conditions that can disrupt TV reception. As there are many similar reports from around the southern part of the UK, that would seem to be quite likely. Do NOT retune your TV set under such situation.
