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?

I was wondering why some of my comments re Sudbury seemed to have disappeared and have just realised UK free tv has two sites for the transmitter. Wonder why.

Dave, if you happen to have a phone a friend who knows about DAB I would be grateful, have posted some qs on the Aldeburgh tv and dig radio pages without success.

Nick: I have just found this Arqiva document on a prospective Suffolk DAB multiplex which does list Aldeburgh:
http://stakeholders.ofcom….pdf
Thinking about the intended coverage area of the Suffolk multiplex (Suffolk!), *relatively* speaking the area left out (uncovered) if Aldeburgh wasn't used would be greater (relatively) than with the national multiplex.
There are more Digital One transmitters coming on air. I know that Scarborough was added a few years back. Due to the terrain, the only reliable transmitter for TV and radio is its own.
I have to say though Nick, from what I can see, you aren't in a valley of which there are a few in the area and of which I assume those living in will have no option but to rely on Aldeburgh. For that reason, I get the feeling that, whilst it is unfair that there are those who cannot get commercial/independent DAB stations, you may be in an area where you can. And if you add to that the fact that you intend to receive at roof level, then your chances must be even greater!

Thanks Dave.
I have experimented with a DAB dipole on a long pole, but only on the shed, aerial about upstairs window height. I can get the radio to log on to some commercial channels, but not strong enough to hear, so hopefully at roof height it might work. I would like to use a directional aerial, but don't know where to point it as the signals are probably either from Manningtree or Mendlesham, but as on same frequency, don't know which. If you have any idea why the commercial channels are on lower power than the BBC, I would be interested to know.
What do you think of a booster 6 inches from dipole for tv?

Nick: Regarding the booster you are referring to what gain do you see it rated as having? and as regards to their use, the only reason they are recommended to be installed as near to the aerial as possible is because it limits the chances of any electrical based interference being amplified if picked up in the cable before it enters to the booster, as obviously the amplifier would boost the interference as well as the signal.
Of course the other reason is, that if the signal is at a higher level before passing down the coax then the ratio of the signal to any possible interference will be greater thereby limiting its effect.
On the other point regarding what you are intending doing with the booster, its not advisable to have it in a plastic casing as that doesn't offer any screening, as even these relatively low cost high gain (13db+ boosters that you can get nowadays made by Vision and others are all contained within a metal casing, and these little devices are excellent.
Also, I don't want to put a damper on your variable voltage idea, but dependant on circuitry used you would most likely find that the variation in gain would be virtually negligible between these voltages as it would have to come down to about 3 volts or so before much of an effect would be noticed.

Thanks JB. It is already in a metal casing, I am just keeping the rain off. I don't know its gain, but it gives the same benefit as a 28db one I have to analogue Dover. The gain does decrease with each drop in voltage, till it does nothing at 3v.
Would you recommend immediately behind the reflector? I only see them half way down the mast.

Nick: Is there any sign of a signal from Oulton on Norwich 11B?

Nick: I can assure you that it doesn't matter that much whether its behind the reflector or about 8 feet or so under the mast, as I can guarantee you that it will not in reality make any difference.
Its just a pity that it doesn't have any names on it though as otherwise I would have checked on its spec, and especially why it seemingly responds so quickly to slight voltage reductions as most dont.

No, KMJ, nothing from Oulton. Do you know why the local and commercial stations are on lower power than the main BBC transmitters from the same site? It seems they want to make things as difficult as they can with coverage. At IP12, they don't provide DAB at all.
JB. It responds instantly to the voltage drop. Perhaps the length of phone cable reduces the voltage a bit.
Perhaps with Dover, where the signal is barely detectable, having the booster immediately behind the reflector captures what little there is, whereas with Sudbury it matters less as there is a good signal to start with. I had to have some means of reducing the Dover signal as it is variable. Most times it is snowy, even with the booster, others it is very strong.

Thanks for the tips Dave, I went old school and looked up, the aerial has snapped of the mast and is only hanginging on by the cable..It not a particularly old aerial, probably 5 years max, I guess the recent winds have done for it.
