The symbol shows the location of the Sudbury (Suffolk, England) transmitter which serves 440,000 homes. 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?

Thnak you for the info, may well give it another go, nowt to lose, we use Sky for most of the TV anyway :-) I know its not analogue but strange how you move from Norwich where you could get Southern / Thames fairly easily, then move 50 miles South and nearer, to Colchester and cant get them at all ! LOL

Steve Williams: Yes, you should give it a try! even if only for test purposes, although if you do maybe you could give an update on your findings as I would be interested in the results.
As far as your comment on reception is concerned, as digital reception basically works on a threshold level system this automatically makes it not near so tolerant as analogue to a less than perfect signal, because if the signal drops to under a certain level the reception will cut out thereby giving the impression that the signal has vanished altogether when in most cases it hasn't, the aforementioned manual tuning procedure by-passing the threshold circuitry provided that search or scan is not pressed, because if it is the threshold circuitry jumps in.

I live on top of a 150 ft hill just 2 miles north of Colchester town center only a few miles from Sudbury ...and when my accredited antenna installer was putting a new antenna on my chimney he said his strength meter told him that the signal was not strong enough to give an adequate digital service ....in fact he actually said he did not like the idea of charging me ..... he was right it often breaks up ... when its raining or an aircraft overflies .... THE SIGNAL ISN'T STRONG ENOUGH HERE .... I hate to think what it is like for people nearly 100 ft lower down in town ... my background includes 30 years transmitting TV

19 Mar, evening, lost muxes using channels 56 58 60. At 9 pm, lost the rest. Weather forecast said fog, doubtless yet another reason for digital to pack up. What a naff set up, bring back analogue!

Has anybody experienced a sudden "break" in transmission on BBC radio and television, on Freeview, from the Sudbury transmitter?
This is definately NOT signal break up but, in the case of BBC television, the screen goes black and at the same time the sound abruptly stops, leaving just silence---no crackling or squawking, etc., associated with weak signal or break up Same with BBC radio---sound just suddenly stops--total silence.
These breaks last around 10 maybe 15 seconds at the most and will come back perfectly. It is if, somewhere, the has been a short disconnection or slow switching either at Sudbury or maybe even at the Beeb I forgot all about this and during recording a BBC tv prog this happened so has spoilt the recording i.e. a GAP This has happened on two different boxes.

Peter, we have to accept that digital is not all it is cracked up to be, Sat is the only way to go, the Sudbury transmitter, radio or tv, gets knocked out by all manner of things to do with the weather.

Satellite is also transmitted as a digital stream, but at frequencies in the Ku band that are not affected by high pressure weather systems (but can be affected by snow and heavy rain due to water absorption).
Sudbury, like many other areas are being affected by 'tropospheric ducting' due to the high pressure weather systems. People should *not* retune their equipment as they are likely to lose more than they gain.

Thanks, Mike, but satellite has few problems, terrestrial packs up at the slightest excuse.

Hi there. I live in Chelmsford and get a good connection to all the channel ranges in Com1 through to 5, but absolutely nothing in the Com 6 range.
Do you have any idea why this maybe please?
