I live in Kesgrave (postcode IP5 2FS) and receive all Freeview channels from Sudbury with only occasional glitches.
I entered my postcode into "My Settings" and was very surprised to see that my "local" transmitter defaulted to Aldeburgh.
Nearly every aerial around here does point to Sudbury (just the odd one or two to Tacolneston) and absolutely none to Aldeburgh.
My mother in law lives in Ipswich (IP1)on high ground with a very good signal from Sudbury and yet her details also seem to default to Aldeburgh.
Is this anomaly simply because Aldeburgh (which only transmits an analogue signal at the moment) is the closest transmitter to us?
I'm not being picky but this does seem a bit odd to me!

Ipswich
IP1 6RL, Chimney aerial installed around 4 years ago in readiness for C/O.
Have 4 year old Panasonic flat screen TV with Analogue plus DVB facilities. Occasional lockups on ITV, ch 4 and 5 on DVB. BBC seems fine. Have always used Teletext on analogue because it seems quicker, but now running on DVB in preperation for start of C/O next Wed, have noticed that quite often it is not possible to get T/Text. Is this a function of signal strength, will it improve after the C/O? The alternative of course is to use a digital box and leave TV selected to analogue on the basis that there is a fault on TV digital T/T decoder. I'm guessing that it would be cheaper to adopt the digi box method rather than pay a repair agent with all the problems of actually transporting a 32" flat screen TV to his workshop.

David, they don't seem to get everything right, even at my location, north of Felixtowe, east coast, they quote Aldeburgh whereas Sudbury is equal strength. Perhaps they forget that on analogue Sudbury dishes out 250kw but Aldeburgh only 10.

David: This site's predictions are unreliable, because it doesn't have knowledge of all the transmitters' radiation patterns, and doesn't have detailed terrain information. Use Digital UK's postcode checker, which is based on the BBC's 50 years of knowledge of how UHF signals travel across terrain, and computes interference from every other transmitter in the country.
It looks like you have clear line of sight to both Sudbury and Aldeburgh, so I'm guessing that the poor projected result for Aldeburgh is either down to the radiation pattern, or due to interference from Crystal Palace, which uses the same frequencies. From November until April, Aldeburgh BBC A will clash with ITV1 from Crystal Palace, while the other two multiplexes clash with low-power multiplexes at CP (though 'low power' at CP means 20 kW). After CP's switchover in April, they will clash with two high-power multiplexes.
You should get a solid PSB service from Sudbury after switchover, but the three commercial multiplexes (A/SDN, C/ArqA, D/ArqB above) will stay on their current channels with little change in power until after Bluebell Hill switches over next June. The prediction, from 20 July, for SDN is variable while no prediction is offered for ArqA and ArqB. After the channel change on 27 June 2012, the prediction for SDN and ArqA is good, but ArqB remains variable. A reception change is shown in 2013 which will drop the COM muxes to variable - this may reflect switchovers on the continent, which I believe DUK always show in 2013, whenever they really happen.

Peter Stonebridge: There is no standard way to access digital text and not all channels carry it. For BBC channels, press the red button on the remote. For ITV1, C4 and C5, press TEXT.
Your TV may show some indication that text or interactive applications are available on the channel. My Humax box shows an 'MHEG' indicator.
Subtitles are always accessed using the dedicated subtitles button on the remote.
Poor signal quality could lead to the MHEG data for the text service not all being decodable, though I would expect you to get some picture and sound break-up as well. If quality is right at the top of the so-called 'cliff edge' you can get poor picture quality without actual break-up, and there might be problems with MHEG at this quality level as well, but it's a very narrow range at which this happens.
DUK predict that your reception of the BBC mux is currently variable. It should improve to 'good' next week.
Do be aware that it is possible to have too much signal as well as too little, and users of Sudbury will be particularly likely to end up having too much signal as the post-switchover digital power is only reduced slightly from analogue, while much larger than pre-switchover digital levels.
