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?

jb38: With reference to the last paragraph of your reply to Alan, the point about different tuners seems to have been proved. Having had no luck with my existing tuners trying (without success) to receive Ch63, I today installed a new Goodmans GDB18FVZS2 set-top box. Scanned for channels, and lo-and-behold, it found 112, including those on ArqB that had previously proved illusive! Compare that with the mere 64 channels the other tuners found.
OK, it means buying more equipment, but Goodmans STB's are cheap (priced as low as £25), and worth the expense if you get all the 'lost' channels back. Of course, there's no guarantee other people would get similar results, but it may be the best option for a lot of folks out there with similar problems.

Tim CO14: Sorry for my delayed acknowledgement to your posting, however what you have mentioned highlights the difficulty in giving advice to anyone with Freeview problems, insomuch that the tuner fitted in the device (TV or box) they are using can be a contributory factor to the cause of their problems, that is coupled to many other factors.
The ironical aspect being that tuners that are inclined to be somewhat lacking in sensitivity generally perform better than sensitive types in situations where the signal strength is a bit over the top in strength, whereas the latter types mentioned score over the former when in weak signal areas.
What really causes problems with Freeview receivers is when they are used in situations where the powers that be have decided that its OK for a stations main multiplexes (e.g: Sudbury) to be operating with an ERP of 100Kw whilst another multiplex is only on 1.1Kw, as it takes an exceptionally good tuner to cope with that type of situation as its one that usually only communication receivers can deal with properly, this because of them having adjustable RF gain controls as well as in some cases variable RF input tuning, rather than in the case of Freeview equipment where both are not unexpectedly fixed, this obviously because of the equipment being very low priced compared to the semi-professional devices referred to.

Mr. J. Carrington: Leicestershire is obviously a very large area where many locations are somewhat screened by either valleys or forests, so you really have to indicate your location so that the reception possibilities as well as other factors can be assessed with the aid of the post code reception predictor, plus of course possible knowledge of the area.

jb38: Thanks for the reply. As we know, the public face of Digital TV would have us all believe that the switchover would be easy, and everyone would get a wonderful service. But spending a year or more on this forum has shown me what a difficult job TV and aerial installers are having, dealing with a multitude of different situations.

Was there an outage yesterday?
I lost Film4 and Dave (ArqA and ArqB) yesterday around 6pm, both from Sudbury and Tacolneston. This was experienced on 2 different TVs and with separate aerials.

having been brought up in Liverpool in the 60s with no football match having less than 44 players, at the start, due to horrible ghosting I was more than pleased when the same old aerial in my mother's house produced perfect Freeview pictures post Granada switchover.
So it was with great anticipation that I looked forward to the switchover in Chemsford (CM2) and wasn't disappointed until..
I didn't figure out why I lost channels when Tacleston switched, I only know now through this august website.
I do feel as though I've been short changed despite also having Sky etc downstairs I do rely on Freeview around the rest of the house and for PIP on my main TV.
I feel sorry for those who totally depend on Freeview, none of my equipment is older than May 2011, seems like poor planing and communications from the switchover team to me.

Brian O'Keefe: You will have to wait until 27th June before the missing channels become available to you again.
Because of the way things are run these days, 8% of the population won't be able to pick up any of the commercial channels using a terrestrial television aerial. They will be limited to the Public Service Broadcaster (PSB) multiplexes which carry BBC TV and radio, ITV1, ITV2, C4, E4, More4, C5, HD channels and a few others.
Some others will be restricted to the PSBs unless they have a different or extra aerial fitted.

This may be the definitive answer.
A OAP friend of mine in Sudbury who has problems with C63, annoyed by the lack of interest with the Freeview Help Line wrote to all and sundry about the unreliable reception, ie BBc, OFCOM, Freeview etc
Well you may think what a waste of time.
However this morning an engineer travelled all the way down from Peterborough to visit his premises and test out his installation.
Sure enough when he arrived C63 was pixelating
After spending some time with test eqpt he told the owner, "there was nothing wrong with his installation which included the aerial on the roof"
He would return to Peterborough to inform his masters that the fault does not lie at the customers premises.
The only other place left is the Mast then ?

Are the frequencies shown on this page definitely correct for Sudbury as of today 7/1/12? I ask as I am trying to make sure I get a Windows Media Centre set up correctly and the frequencies here seem to contradict what the Ofcom switchover document says:
BBC A Ofcom: 44 here: 44
D3&4 Ofcom: 41 here: 41
BBC B Ofcom: 47 here: 47
SDN(A)Ofcom: 49 here: 49 (will move June 2012)
Arq A Ofcom: 60- here: 54
Aeq B Ofcom: 56 here: 50+
As you can see you disagree on Arq A and Arq B.
I can see so many signals where I am (aprrox 10 miles North of Sudbury) that signal strength at any moment is very variable so I want to tune to the definitive signals off Sudbury which is on average the most reliable signal.
Thanks
