I've been experiancing exactly the same problems over the last couple of days BBC 1 is fine, but ITV 1 and channel 4 breaking up. Again signal is 9o% and another tv on a different aerial gives the same prob.

I suspect you are all getting reception problems due to high pressure (Inversion effect), I live on the fringe of Sandy Heath and as soon as there is high pressure I lose channels, I notice as the evening progressed on Saturday evening blocks of channels dropped out, There maybe other factors involved in all your reception problems but this is a possible problem you are all having, Others on here maybe able to advise further.

As Tim from Radlett rightfully stated above inversion effect was the cause as i last night between 9pm-11.45pm was briefly receiving transmissions from BBCA mux on frequency 23 and D3+4 mux on frequency 26 both from Crystal Palace,plus BBCA mux on frequency 27 and D3+4 mux on frequency 24 both from Sandy Heath ironically enough,as well as BBCA mux on frequency 61 and D3+4 mux on frequency 54 both from Waltham,yet losing both the BBCA mux on frequency 22 and D3+4 mux from frequency 25 for a time both from Belmont (now in my 800's list) at my location.

The last 2 nights ive been losing channels. Monday night ALL stations went to 'no signal' and were down for hours. Then Tuesday night they were dropping in and out and pixelating.

Tim: Cd's wont jump or skip, Stains can be removed at 40 degree wash or less, Digital TV will be better than the old UHF/VHF and less liable to atmospherics - all misconceptions designed to facilitate the sale of new products - The transmission footprints are too big we needed Morborne to be set up for peterborough/stamford digital transmissions - Pixilation and signal dropout on the lower arrays will continue as long as the earth refuses to be flat and air pressure/weather systems exist....

It is not so much that the frequencies are dropping out because they are too weak, it's more a case of receiving several transmitters on the same frequency. You only need to look at the signal strength to understand that.
It is unfortunate that the best content, namely the BBC channels, is on the frequency with the highest level of interference. I would not miss some of the rubbish on the other MUX frequencies.

I live in central northampton NN1 1PB, I have no channels in categories A or C at all.
When I rescan I am only given the option for Cambridgeshire & Bedfordshire, is this the closest transmitter?
Beige the changeover I received all of these channels but since rescanning in June I have never received them.
Is this due to engineering works or is there something more I can do?
I have freeview built in to tv and live in fairly new bloc of flats so assume aerials and such will be a high standard.

jb38: thank you for all your help, i got one of those one for all signal splitter/ amplified 10x gain which takes up to 4 tv at a car boot this morning for £1.50 ( selling in PC World for £29.99 ) so i thought id give it a try, and it works !!!! i retuned my freeview box did an automatic search instead of a manual and ive got perfect tv now, even all the station i could only get before when it rained are now there, and at a bargain price !!! i would never have thought of getting one of these if you hadnt suggested it, so anyone else out there having problems look for one of these, its called one for all signal splitter sv9542 . thanks again Suzy

Suzy: Really pleased to hear that you have had an element of success with your "bargain" purchase as signal boosters do serve a purpose if used correctly, and indeed in lots of situations is the only way of keeping a signal above the cut off point, this known as the reception threshold.
That said though, should any erratic element creep into your reception again and possibly because of the tree situation or even atmospheric conditions, something which has been affecting various areas, please!! try to refrain from being tempted to try altering anything and especially as far as retuning is concerned, as all you will do is upset everything you have achieved.
Anyway thanks again for your update, as its nice to know the outcome of a persons problem.
