I live in Stilton and for the last 2 days have experienced signal loss or signal delays( picture freezes for a second) constantly on ITV, channel 4 & 5. Have tried retuning etc but still the same. Have checked with someone else in my village who I know is on freeview and they're experiencing the same problems. It's starting to make these channels unwatchable with all the jumping etc.

Claire: I live in the Stevenage area and receive Anglia TV. Since Saturday evening September 1st at about 7pm the signal started breaking up and the picture was blocking. This lasted until about 10pm. This problem only affected ITV1. I did a reboot on the TV and Freeview box but this made no difference. Again last night at about 7.50pm the sanme thing again. I know it is not my box of TV as my second TV was the same. I live in a block of flats which has a communual aerial. What can I do as my reception on this channel is unwatchable.

I have had similar problems on Sunday evening,with Sandy Heath on ITV1 Ch4 and 5.

Signal strength very good 84%(as normal) quality 100%(as normal) Humax Fox T2, Loewe TV and Panasonic TV.

Could well be a transmission issue on this multiplex as there is no indication that the signal is poor.

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.

Claire, Mrs Arendse, Russ, Larry
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.
