The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Sudbury (Suffolk, England) mast?

Sudbury transmitter is giving VERY poor signal to CM2 for Film 4 etc. This has caused intermittent loss of service for this since 5 Apr 2012 which can be restored by automatic or manual retune. It seems totally unreasonable to have to wait for 27 June for signal upgrade to restore service.

My Yesterday, Film 4 and ITV-4 signal was lost last November in CM8 (Witham). Friends living a mile away can still get Yesterday!

John
you have lost these channels due to signal levels being low, do you have a wideband aerial and/or any amplifier on you aerial? if you still have an old aerial oyur options are either new wideband aerial or wait until june 27th retune when the multiplex changes to channel 56 from its current 63

John Chambers: And if I could just add, that purely with reference to the last part of your posting re; Friends living a mile away, in areas where reception from a lower powered mux channel is generally received on the weak side its not exactly uncommon for a person on one side of a road to struggle with reception whereas the signal is reasonably OK on the other side, as even a distance of only a few feet can sometimes show large differences in signal strength.

John Chambers: NOT that I am suggesting changing anything, as the low powered commercial channels and especially the one you are having problems with (ArqB 2.2Kw) all switch over to 100Kw operation on the date mentioned, something which will eliminate the majority of problems such as the type experienced by yourself.

James, you haven't given your postcode so it's difficult to tell, but for most people this situation is caused by not enough signal on the multiplex which carries Film4 etc (COM6). Because of the need to not interfere with adjacent TV areas, this multiplex was temporarily moved, in November, to a higher channel number than is ideal and set to a very low power. As a result of this, many people on the Sudbury transmitter cannot receive Film4. This should be cured on 20th July, once Dover have had their digital switchover and COM6 moves to an easier to receive channel and is boosted to the same power level as the BBC and main ITV multiplexes.
If it is a case of distance from the transmitter, my recommendation would be to upgrade the lead from the wall socket to the TV itself to a quality item - it's easy to make them up and you can get the wire and the connectors in DIY stores. After that, you should try to upgrade the main cabling (in both cases here, use double screened satellite quality cable). Next, it would be interesting to see if a small amplifier would help you out, but I would recommend borrowing one first because you won't need it in 3 months time after the July retune.
There is, however, another type of issue and that is actually caused by being too close to the transmitter. If that is the case, the high power received from the BBC and ITV multiplexes swamps the receiving circuit in the box and ruins reception on the lowest power channels. In this case, the solution is less power and not more. Check out Freeview signals: too much of a good thing is bad for you | ukfree.tv - independent free digital TV advice in case that is the problem. Even if it is not a case of too much power, there are still some good tips on that link that you should check out about tuning. (IP142JJ)

Norm De Plume/James Elliston: Sound advice! Sorry to be picky Norm, but just one tiny error - the date for the last Sudbury re-tune is scheduled for 27 June 2012, when ArqA and B should return for those who have missed it!

James Elliston: Woops sorry guys, I live in Halstead postcode CO9 1XE so not that far so might be a question of too much power guess will have to wait till the 27th June and see what happens thank you for your responses (51.9360,0.6357)
