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?

Hello Guys

My free view in my TV has suddenly lost most of its channels

I am only able to see channels on COM5 all of the others are missing following re-tune and full restart

Is it likely my aerial needs looking at as Sudbury report no issues

Post code cm7 4ld

Thanks

Jod
