Hello Nick,

On an analogue picture another unwanted analogue signal on the same channel causes the herringbone' and buzzing effect you have been used to over the years.
On an analogue picture another unwanted digital signal on the same channel causes the picture to become snowy and in extreme cases disappear completely.

On a digital picture an analogue signal on the same channel causes pixilation , sound drop out and lock up. in extreme cases the picture disappears.

On a digital picture another unwanted digital signal on the same channel will cause the same as above but it will happen a lot quicker than analogue interference.

This is how I understand it anyway!

The best thing I can say with Sudbury is wait and see. The signal will be raised in July but you are in a vulnerable position. All the coastal Dutch channels were already using different channels to Sudbury to try and reduce interference (except CH5) but the sea path is so good for carrying unwanted signals that likely you could get hit from transmitters as far away as France and Germany.

In addition they are moving the Sudbury channels around again after July 2011 so what might not be great then could be ok later. Also bear in mind for most of the year and especially during the winter there will likely be no problems at all (cold comfort I know if you are trying to watch the world cup final in June) !

I would think if anyone is getting herringbone' problems on Aldeburgh now it is likely to be the huge mast at Crystal Palace that is causing the problem. There is no analogue left in the low countries and Northern France.

There is no way of telling just how good Sudbury digital will be after switchover where you are, you only have to move the aerial one metre and the signal would be different.

What I would say is that although the coastal area is obviously low lying there is probably not a huge hill between you and Sudbury so I would hope the main channels BBC1/BBC2/ITV1 etc would be able to penetrate after power up. Greater brains than mine will be able to answer this though.

I will leave your CRT v Flatscreen question to someone else. It is something I have heard several people comment on but again someone with greater technical knowledge than me will be able to comment..

Thank you for such a long and detailed answer. It is snow and near loss of picture. Seems like the dutch digital IS doing the damage to our analogue. I thought the path of digital meant it didn't bounce down.I suppose we will have to wait and see if their dig hits our dig.
please don't forget to comment about flat tvs, if that is in your remit.
Thanks again.

I live in IP4 in Ipswich. I have a standard rooftop aerial. I can receive all of the analogue channels and most of the digital but seem to be missing those digital channels on Mux2. Do I need to switch to a wideband aerial?

Nick: Flat panel sets are much, much better than CRTs, and this is often the problem, they show up faults in the picture that are blurred by a CRT.

If you have an LCD or plasma display and find the picture is not as you expect, turn off the "sharpening" feature - and other visual enhancements.

HD pictures are clearly much better than SD on analogue or digital, if you can't see so, then you are probably not looking at an HD broadcast.

Everything on BBC HD is 1080-line HD, but not everything on BBC One HD, Channel 4 HD or ITV1 HD is sourced in HD.

Thank you once again, Brian.
As you can see, I am giving a lot of thought to going digital. A friend who works in the tv repair business tells me two freeview boxes in his house packed up within an hour of each other and he has experience of numerous others not lasting long. Is there any underlying reason for their unreliability, can it be power surges, can they be protected, are some more prone to pack up than others? I do not want to spend several hundred pounds on a freeview tv only for its tuner to pack up.

Thank you for that, Brian. Are freeview boxes less reliable then, and why? Would it be any benefit to plug tvs and boxes into 4 gang surge protected extensions?

Nick: You can get Freeview boxes for as little as £20, sometimes less. They will usually work for two or three years, but they often fail after this time because they are on 100% of the time and the quality of the components is lower.

You can surge protect your equipment - all my computer equipment is on a surge protector that was pulled off a PSBX about 20 years ago - if you want.

UK mains electricity rarely has brownouts, if you had poor wiring and equipment with dirty switches (such as cheap thermostic equipment) a surge protector might be a good idea, if you don't then it would be a waste of money.

Dear Brian,
Thank you once again. £20 is the most I have seen locally for a box, Labgear. Don't suppose you can recommend one?
Can we not switch them off when not watching? Pull the plug? Or would that cause other problems? Presumably the tuners in sets get a rest because we switch off the tv, so they last longer.
Best wishes,
Nick.
