Sorry Brian, a bit more.
The Bush freesat box--does it get HD?
Is it prone to a short life like the freeview boxes recently discussed?
Around Christmas there were some good make tvs with freesat tuner, and a 5 year guarantee. Now there appear to be none with either of these in my desired 32/37 inch preference. Panasonic was the one I looked at earlier as it seems flat tellies by and large have attrocious sound. Any good freesat tvs you know of, really don't want a mountain of boxes!

Nick: The reason that your reception from Aldeburgh will change is that the shifting sands of UK and international frequency allocations during the last phase of digital switchover will result in some potential interference occurring to your Freeview Lite reception from Aldeburgh.

As for Freesat, if you already have a dish you just need a quad-LNB fitted to provide more outputs. They are £30 - Buy Quad Output Sky/Sky+ LNB at Argos.co.uk - Your Online Shop for Free to air satellite.
.

This is because each LNB in the package requires both a power supply and signal to select the appropriate signal polarity.

This does mean there has to be a cable from each receiver (and "+" boxes have two) to the LNB.

Nick: The £30 box is SD, the HD ones start at £80 - Buy Bush Freesat HD Digital Box - Black at Argos.co.uk - Your Online Shop for Freesat digital set top boxes.
.

You can get Freesat HD TVs, but they are perhaps no cheaper than an HD Ready set with a box.

Dear Brian,
I hope I give you time to answer other people's questions !
I think you have covered all, and it seems digital is not going to be easy without a mountain of wires and boxes. I wonder if the elderly here will get all this for their £40.
I am asking these questions on behalf of IP12 and IP15. I still do not appreciate the reason we have to get off to a good start with Aldeburgh and then get interference. Where will this interference come from?
Can I assume that at least in Aldeburgh itself, IP15, the signal will be good all the time, before and after we have to put up with interference at IP12? The digital people really should not be allowed to mess us about like this and expect us to buy piles of boxes and have numerous holes in the wall and coaxes.

Oh, just one other, these freesat boxes, do they last longer than the freeview ones you said last only 2-3 years?

Nick: The Help Scheme will provide additional help to people in areas with no predicted Freeview reception, above the £40 norm.

There are no such things as "IP12" and "IP15" regarding reception. Your exact location determines the services available. Just moving a few hundred meters can change what you get.

I'm sorry, but as you are part of the 1.5% who are outside the official terrestrial coverage area you will need to provide for satellite coverage.

Many thanks again Brian.
If you could just confirm that in general terms reception of the Aldeburgh transmitter should be ok in Aldeburgh itself,even when the interference you referrred to some time after switchover is inflicted on us, I would be grateful. Some indication of why reception will later receive this interference would also assist, ie, where is it coming from?
Are the sat boxes you suggested more reliable than the freeview boxes you said last only 2-3 years?
Kind regards,
Nick.

Nick: For the coverage of the Aldeburgh transmitter, see Aldeburgh digital switchover date | ukfree.tv - independent free digital TV advice .

I would have thought that the incoming signals could come from Belgium, the Netherlands and France.

Generally speaking, I think you will find that the Freesat boxes are usually built quite well and should last several years.

Dear Brian,
You have been extremely good in answering so many questions and I had better let you alone to answer other people's queries. I still do not understand why the Aldeburgh xmitter is to start off well and then later be the subject of interference. Doubtless there will be a lot of complaints when people start off well and then for some reason which we do not understand have to be downgraded to receive interference, by which time it will be too late to demand our analogue back until they fix the problem with the digital. Whether the interference is to be caused by neighbouring transmitters or some reduction in the transmitter power, we will just have to wait and see.
Incidentally, you said herringbone on analogue is caused by other analogue transmitters. Sudbury is currently provideing some herringbone on analogue BBC 1. With Dutch xmitters now digital wonder where it is coming from. Best wishes.

Nick: There will be NO reductions to the transmitter power at Aldeburgh (or anywhere else) as I said above that it will be incoming international signals that cause interference.

I would guess your "herringbone" is being caused by Bluebell Hill, which is directly "behind" your location and uses similar frequencies.

"Dutch" signals are unlikely to cause you problems at your location as they are at 90 degrees to your line of sight.
