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?

Many thanks for your replies Guys.

I can't tell you anything about the exact quality I'm receiving, I wouldn't know how to find out - this is an integrated tv, I can't see any mention on the menus of signal strength etc., but the rest of the channels work fine.
The aerial is 20 years old.
The page on single frequency interference would seem to apply, however, I'm baffled really because I have not changed anything - there is no equipment connected - no Sky, or other boxes, and the aerial has not changed. The only change has been the retune - after the final phase, the channels referred to as group D have disappeared. I've tried retuning three times to no avail. And I don't feel I should have to buy a new aerial when the one I have was working before the retune.

When SUDBURY completes it's changeover in mid 2012, will SDN and the two Arq mpxs increase their power to anything like the 100kW of the other mpxs?

Peter: Yes, exactly 100 kW.

The coverage still will not be equivalent as the commercial muxes have chosen to use a less robust, but higher-capacity mode. They have started making this changeover already. In addition, the PSBs got the best channel allocations, the commercial muxes will be subject to greater interference from other transmitters.

Finally, Rouncefall's transmissions help to reinforce Sudbury's coverage in many areas, but it only transmits the PSB services. The COMs get no help from Rouncefall.

I subscribe to BT vision and Sky spotrs 1 ans 2 on channel 41 and 42 the pixlatinf picture I am in an aere betrween Talconston and Sudbury but point to Suddbury. I was amazed when my Aerial supplier came to find that Sudbury was not up to full strength yet
Why did it cost me £40.00 to find this out.
We all do not know technical issues and I am very disappointed in the Non info from the digital switchover team. I ubderstand that the Sudbury transmitter will not be upto strength until June.

Val S: Just purely out of interest I wondered if there was any reason why the aerial installer didn't use Tacolneston rather than attempting to get Sudbury @ 27mls? and which as you were informed is operating with very low power on the multiplex that the programmes referred to would use, but Tacolneston @ 18mls is already on high power and is indicated on the reception predictor to having the edge on Sudbury even after it switches completely to high power operation.

Of course its appreciated that there may well be some local reception difficulties applying to your area which will not show up on post code predictors, but I was just curious.

We're at IP6 0LQ, and haved lost all channels on ArqB this weekend. We receive our signal from Sudbury transmitter, and have been trotting along fine for ages now. We've had all aerial, cable, connectors checked recently, and are currently having no issues with any other channels. Anyone else out there having the same issues? Have tried a manual retune on 63 and 50, 51 & 52 and "no channels found". Thanks

Elaine: Its pity that you carried out a re-tune as you will have lost ArqB on Mux Ch63 from the TV's / boxes memory as otherwise I would have requested that you to carry out a signal strength check whilst on ITV4 etc, because its likely that the signal had just dropped under the reception threshold level and which would have returned when the it lifted again, as the signal level will still show even although there is no picture.

The reception predictor (trade view) isn't really of any assistance on your particular area code either, as it in effect indicates that you are in a black spot for reception from Sudbury and with no reception from commercial muxes being possible until June, so even although you maybe can receive them there has to be an element of pot luck about it as they are very low powered, so about the only thing you can do is to keep trying a manual tune on Ch63 every few hours until it returns to a level that the receiving equipment can lock on to.

By the way, the commercial multiplexes such as one of that's causing problems, wont be switching over to high power until June 27th when a re-tune event takes place.
