Hi Jim. Thanks for your response.
Still no luck. Tried all combinations and permutations of resets, retunes and software updates. Even tried letting it half tune then taking aerial co-ax out and vice versa then total power off, reset and retune. Same. I don't know if this is relevant but I don't get any channels above the 700s (Samsung sir u-2001 digibox can apparently go up to 999).

joe - I think what you will find is that the signal now is phenomenally strong where you are - can you actually see the top of the transmitter - if so your box is probably being swamped by too much signal
nip into ATV at hillsbourgh opposite back entrance to the barracks where morrisons is and get an attenuator - they do a various ones you probably find it will work once the signal is reduced
The aerial installer would have installed a wideband aerial - you obviously received analogue BBC 2 as you state you now miss it - the new BBC channels are where BBC2 analogue used to be !

if not they're about a fiver so you've not wasted much

Hi Keith. Thanks for the advice. Yep, I can see the transmitter from where I'm sat and the signal is very strong. Fortunately/unfortunately, a CRT we had upstairs died last night in quite a melodramatic fashion so I nabbed the digibox from it and plugged it in to our main telly. Everything tuned in. Job's a good 'un. Should've tried the other digibox before...
Thanks again.

Hello, I live near Meersbrook Park Sheffield - but have always needed boosters even after a new aerial. Good pics on all channels following retune but HD signal strength is only 9 - will this improve? and is a signal strength of 9 (on a new 32 full HD Panasonic TV)likely to affect the picture - not sure I can tell any difference from the revived DVB at the moment.

Mike: 9 is very good. You do not need to max out the signal strength - what is important is that the signal quality stays at a very high level. I'd leave it alone, or possibly even take out the booster.

Transmitter engineering:
Signal in Retford was fine untill last night, used to get 79-81% on all channells, now it has dropped to 74%
What has happened ?

Robert Mansell: It looks like you're probably actually using the Emley Moor transmitter, which is yet to switch over.
Early yesterday morning, the Chesterfield transmitter completed switchover, and started using C40, C43 and C46. These clash with multiplex 2, A and B at Emley Moor for the next two weeks - the clashing transmissions from Chesterfield are deliberately on low power to reduce this, but you're quite a way out from Emley Moor so it's affecting you more than most.
Switchover starts on the 7th of September for you, when BBC Two analogue switches off, ITV1 analogue moves to replace it for the two-week switchover period, and high-power BBC digital replaces that. (Low-power Multiplex 1 shuts down. Multiplex A moves to replace it for the two weeks between stage 1 and 2.)
On the 21st, the remaining analogue services shut down, along with the remaining low-power digital services, and the remaining high-power digital services start up. On both days you should retune after 6am, when all changes should be complete.
74% is still a very healthy signal level, you could actually have too much signal after switchover.

Hi Mike,
Further to my question a couple of days ago (when I thought I was using Emley Moor), I have worked out that I'm receiving my signal from the Sheffield transmitter. My aerial is vertical but I'm only receiving PSB 1 and 2.
Signal strength is still very strong. You've been very helpful so far, thanks

Simon: Did you have digital before switchover started? Did you get Channel 5 analogue clearly?
If the answer to either of those was 'no', you may still have a Group A aerial, which was all that was needed for the four main analogue channels. It's sufficient for the PSB multiplexes, but for the commercial multiplexes, you need a wideband aerial. You would have needed a wideband for pre-switchover digital signals, and for Channel 5. See 'All about aerials' for information on the groups.
A Group A aerial should have a red plastic cap on the end of the aerial boom; a wideband would be black. It may not be very easy to see this, though. If the aerial is more than 15 years old it's likely to be Group A.
People *very* close to the transmitter might still get enough signal in the B-group channels to be usable even with a Group A aerial.

Hi there,
I wonder if anyone can help. I recently moved house in the S10 Crookes area. I've literally moved 3 streets away from my old house. In my old house I got all HD channels fine. I then moved house and got HD channels for about 5 days until the end of July when one night it just said "no signal" on all of the HD channels. I suspected it to be caused by the messing around with the transmitter so I retuned and then lost all trace of the HD channels. I thought we'd probably get them back after all the work on the transmitter was completed and the switchover was complete but we still can't get any HD channels today.
I have a new (4 month old) LG 37 inch Full HD LED tv. The aerial is in the loft and it's a rented house so I can't really go up there and fiddle about.
I've tried searching to see if anyone else has had the same problem but no one appears to have said anything on any of the forums (that I can find).
I can pretty much see the transmitter from my house so I don't understand why I can't get the HD channels and after an expensive move I can't really afford to pay for any engineers to come out so any advice would be most appreciated.
Many thanks.
