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?

Nick: Most boxes and sets have ultra-low-power stand-by modes, but you usually leave them on to allow overnight EPG and firmware upgrades.

Brian, you are being very good answering all these questions. I hope your answers are useful to others.
I assume you cannot recommend a box, but I have seen nothing other than cheap lately.
Sorry to be dense, but say you switch off the box overnight or even a couple of weeks when on holiday, would it not 'catch up' with the info it requires? After all, when they are in the box at the shop, they are not 'learning' anything.
Kind regards,
Nick

Can't speak for Brian's box, but my Humax PVR-9200T has to be put in standby for it to get firmware updates. We've already seen numerous reports of people running very old firmware on this box because it was never put in standby, and experiencing problems that were fixed a long time ago.

The EPG data is transmitted at a pretty slow rate by the broadcasters - it takes a few minutes to trickle in. They broadcast about 8 days' worth at any time - if they happen to be broadcasting day 2 when you switch the box on, it takes a little while for it to get back round to today. It's like reading a long article on Ceefax.

Newer TVs and boxes, particularly PVRs, save the EPG data to persistent memory so that it's instantly available when you switch back on. (After the most recent update to my Humax, it now saves the EPG data to the hard disk when you put it in standby.)

Post code IP13 9EL, Pointing at Tachleston, and keep losing ITV1 etc (mux 2) (on channel 60) have to re-tune to get them back. Why is this suddenly happening, as i have been using freeview for about 3 or 4 years now, with no previous issues?

chris stevens: You are not predicted to get a multiplex 2 signal from Tacolneston until 23rd November 2011.

To be honest, at your location, you are probably better using Freesat.

You are probably being effected by the recent changes to the digital in France and the Netherlands.

Dear Brian,
I am still trying to work out what best to do when Sudbury goes digital in July in a coastal area which might suffer interference from Holland. I have a 'free' Sky box.
If I go for a freeview tv and suffer interference, I can watch on Sky, but for recording, in order to avoid interference, is there any reason I should not be able to record on a freesat box and watch the recordings on a freeview tv which has no freesat tuner? I do not want to have yet another box, ie freesat.
Can the freesat recorder use my Sky dish as well as Sky using it, or is connection difficult? Many thanks, Nick.

Nick: As you are not predicted to get Freeview reception of reasonable quality, I would suggest you get a Freesat+HD box.

You can use a Freesat+HD box with any sort of TV you like.

Yes, you can attach Freesat equipment to your existing LNB package.

Many thanks yet again Brian. I did not realise we were not even predicted to get decent freeview here. Clearly the Sudbury digital service will not cover fully the area currently served by its analogue service. Those in charge should not be permitted to switch off analogue till they find a way to replace it properly.
I have made enquiries about a freesat recorder, seems like I would need a multiple lnb and 2 more holes in the wall and cables.
I am getting fed up with digital even before it starts!

Nick: According to the "system", your analogue transmitter is the one at Aldeburgh, not Sudbury.

At some point Aldeburgh will give you a good service, but this will move to "marginal" in the future.

The analogue, and therefore digital services cover 98.5% of the population.

You are in the 1.5% that won't get a decent terrestrial service, and for you Freesat has been provided.

Freesat boxes start at £30 - Buy Bush BFSAT02SD Freesat SD Digital Box - Black at Argos.co.uk - Your Online Shop for Freesat digital set top boxes.
- and you can get a dish fitted from £89 - Buy Single Freesat Installation at Argos.co.uk - Your Online Shop for Freesat accessories.
.

Freesat HD will provide ALL the channels you will ever get terrestrially, and you can have them today if you want.

Dear Brian,
You are remarkably helpful, thank you.
Please would you explain what you mean by Aldeburgh will move to 'marginal' after a good start. Here at IP12, Aldebugh analogue indeed provides a signal equal to Sudbury but I am reluctant to use it as the digital channels will be few, cannot even be sure ITV3 will be included. Nevertheless, when push comes to shove, will its digital be ok here?
Freesat, have the Sky dish already, seems to require more cables and lnb changes. Why we cannot hook up all these gadgets to one coax from the dish is beyond me.
