Hi Jason. I listen to Radio 4 on FM and sometimes via my tv. If I walk between rooms it can be bit weird as the tv is about a second behind the FM radio. From what I've heard, the speed at which digital decoders works varies from product to product, so assume that expains the difference you experience. The 'pips' when received digitally are very slightly out of sync.

Please would someone give me an address or phone number of whoever I should contact re reception problems from Sudbury on Arq A only? I get all other muxes, and turning the aerial, various other transmitters, but Arq is usually not there at all, or pixelates.

Nick, Sudbury is not intended to cover Aldeburgh - that's why Aldeburgh has its own (Freeview Lite) transmitter on the outskirts of the town.

Thank you, Heinz, but that does not explain a 90%+ signal quality on all muxes apart from the one using ch 60, which can sometimes be zero.

Nick: Try using another tuner/digibox. If you then get Ch60 with a different tuner, that would suggest a fault with your current one.

I have, Tim, all the same. With the same aerial turned, I can get Clacton, Dover and Tacolneston. I am sure the transmitter is not all it should be.

Since Sudbury turned off analogue completely, and turned up the digital transmit powers, I cannot get any of the stations on c58 or c60. All the others c41/c44/c47/c56 are excellent, with usually 100% signal quality and 75% or better signal strength.
I have a new (this year) 25dB MHA with a 48-element aerial and satellite grade cabling (new this year) throughout.
I have tried three different receivers of two different brands (Philips, Echostar) with the same result.
Any ideas anyone?

You don't say where you are Rob but those symptoms are eerily similar to a receiver being swamped with too much signal (although why that should only happen on those 3 upper channels is beyond my simple mind).

Rob Shepter: Should you be the person residing in the CO1 area and originally using a Philips DTR210 then, and as mentioned by Heinz, you "might" be receiving an excessively high signal level by being located about 10 miles or so from Sudbury, especially with the type of aerial set up you are using, which I must say does seem rather excessive at this sort of distance from a 100Kw transmitter.
The other point is, that although the terrain predictor does not indicate any obstructions in the signal path between the transmitter and you, this type of indicator cannot really be classed as being highly accurate by only showing ground levels and nothing else, so in real life is there any obstructions that you might be aware of?
Regarding the 75% strength indication that you have mentioned, what happens to this level if you switch off the mast head amplifier "whilst observing" this indication? although ideally I would have been more interested in what the indication would be if the amplifier had been by-passed, but if of a mast head type then that's obviously not possible.
And with reference to the mast head amplifier, if when its switched off you can still see a signal level being indicated, which with a strong signal you should do albeit that the picture may have vanished, then go into the tuning menu / manual tune and enter Ch58 or Ch60 and check if any level is being shown, no need to scan.

I live on the border of the Sandy/ Sudbury transmitters location CB10 2HB with the ariel pointing to Sudbury. I am now getting pixelation and signal loss apart from Ch58 on a new Panasonic TX-L42ET5B (which shows 100% signal strength but 10% signal quality on the problem channels), no channels apart from Ch58 on a Tvonics LT3 and no problems on the old Philips set top box or the Sony Bravia KDL-32S5500. Problems are intermittent mostly early evening and started happening about 2 weeks ago, everything AOK up to then. Any ideas?
