Richard Owen - you are likely to be suffering from too much signal. If you check out the post 2 above yours that situation is covered at the bottom.

It should get a lot better on 27th June when all the signals will be broadcast at the same level.

IN the last 2 weeks we have pretty much lost the ITV4/Yesterday/film 4 group with total breakup of the picture. Up to this time we have had no problem at all. Based in Coggeshall we receive from the Sudbury transmitter. Any enlightenment on why this has happened all of a sudden. As I understood it the last work was back in November and things were fine after that. I have done several retunes to no avail.

@Jill - its surprisingly straightforward, there haven't been enough leaves on the trees since November to affect the signal. However, in the last couple of weeks, the sap has risen and the leaves have sprouted. Up until now, your signal has been borderline, but the effect of the water in the trees and the leaves has been to push the signal down just that little further and your signal is now at too low a level to receive the weakest signals, i.e. ITV4 etc.

The good news is that the signal will be massively boosted on 27th June as a result of the last stage of the digital switchover for Sudbury, and you should then have the same quality of signal as you do for BBC1.

jill: It could be trees, but it could also be a dodgy flylead (from wall socket to TV - try a different lead), or possibly water in the coax cable from the aerial (Arq B MUX would be affected first since that's the highest frequency - until 27th June when Arq A MUX will be the highest frequency).

Jill - thanks for the reply, you'd be amazed how many people pop in, ask a question and are never heard from again, so your reply is appreciated :)

With only a month to go to the power increase, there's not a lot of point looking at more complicated checks, but JimF's suggestion about the cable is well worth considering - replacing a low quality cable from the wall to the TV with a good quality one can make all the difference in your situation.

If you haven't got a good spare cable, I would advise against buying the typical DIY store rubbish. Instead, have a chat with a friendly aerial installer and ask them to make you up a lead with some decent quality double screened cable. Alternatively, satcure stock them - Coaxial WF100 digitalSatellite cable Sky and Freeview extension leads double screened

Tx guys, the aerial system and cables were all set up last year by Bennets a very reputable aerial specialist in Colchester so Im guessing we just have to hang fire for the power upgrade in June. It is just literally the last few weeks where its all gone on those specific channels. I have recordings from March from the channels where everything was fine! #drums fingers and sighs deeply#
