Tuesday retune for Sheffield and Nottingham
Brian Butterworth published on UK Free TV Today, 27th September 2011, there are final changes at two transmitters:
At Nottingham the SDN multiplex moves to 8k mode, and moves from C67 down to C51; also the ArqA multiplex moves from C63 down to C52 and goes to full power.
At Sheffield, it is the ArqB multiplex that moves from C63 down to C39 today.
Help with Freeview, aerials?

Dave Jenks, ,my parent have on of those expensive but 'easy to use Humax' boxes.
I was always picking up weak Sutton coalfield signals on it. The solution for me was to lower the aerial and retune to get rid of those weak signals which block the stronger one as they are found first.
You may be able to achieve the same result by fitting an attenuator (something to weaken the signal). It may also be possible to individually tune in a channel but I found the Humax box a bit of a 'pig' to understand.
Their house was a bungalow so it was easy to get at the aerial. Basically you need to find a way of weakening the signal so it missed the bad signals completely. Maybe a bit of badly shielded cabling might do the trick?
You would only need it for the tuning. Or just running it through a long extension cable to, or buy an attenuator on ebay perhaps?

Hi, I have a full HD tv, last week stopped getting all channels on C39, ArqB multiplex, previously no problems. Not counting intermittant poor reception.
Live in S10 area.
No analogue interference, same shared ariel.
Could anyone give me some pointers?

Hi mycloud, it might possibly be that following changes you are picking up a weak signal from waltham instead of the one from nottingham. I know the Humax set top boxes tend to do this. Afterall if they get the same mux from two different transnittors they have to decide which one to store, some may store both so perhaps you have the channels stored on higher numbers ie 800+?
So weakening the signal when tuning (or permanately might cure it. YOu can get a variable attenuator on ebay for a few quid.
YOu could even try making the cable longer or putting in a bad section (some insulation missing). Basically anything to reduce the signal.
Or maybe you simply need to retune mycloud?

Thank you for the advice Brendan.
I think my main transmitter should be the Sheffield one, being closest to it.
Retuning has not helped.
Freeview tuner is built in. Retuning has not helped so far. Will look into attenuators.

mycloud - you are not supposed to get anything on 39 but should get on 49.
Try a "factory retune" or "complete reinstall" of channels - names vary.
And trey retuning with no aerial at all - though your huge signal (95dBuV/m)
UK digital TV reception predictor
means you might still get something.
What ae are you using? Bent wire should be enough! (LL145HD)

Steve P: That information is out of date. It came from an Ofcom document (licensing section) that has been superseded and wasn't consistent with a different Ofcom document ('stakeholders' section). All sources now agree that ArqB has moved from C63 to C39, now that Emley Moor's early HD service is no longer in the way.
mycloud: Given you are practically on top of the Sheffield (Crosspool) transmitter, you probably do have too much signal. See Freeview signals: too much of a good thing is bad for you | ukfree.tv - independent free digital TV advice .
Do be sure that you have done a full factory reset, exactly as you should have done at switchover; many boxes simply can't handle a multiplex moving to a different frequency using the 'add channels' function.

Thank you everyone for their input...much appreciated!
I am also baffled as to why I suddenly have this problem, prior to last week have had near perfect reception.
Will try factory retune again, although have followed this websites instructions of retuning without cable, to clear channel list..

brendan: mycloud, I put your postcode into the wolfbane sitet and it seems you should get a strong signal from the Sheffield transmitter and only need a set-top aerial.
But presumably you had a strong signal before the anyway?
I am in Nottingham and I also have (slight) problems on the moved mux. I also had perfect reception until about a week ago.
Also mycloud I would check the channel number of the channel with interference and make sure it says C39, it maybe the mux got overlayed by the same mux from a more distance transmitter. This happen on my parents TV, I fixed it by laying the aerial on the ground and retuning so it could not find the weak signal.
The may also be a way of manual retuning C39 where you specify the channel to search for, try that.
A bit of co-axial cable connected to a metal coat-hanger might be good enough for you.
I have been getting a bit of interference on mine again today on C52 but it's a negligible problem really.

Hi
Any ideas why my Sky Sports 1 and 2 on my BT vision have suddenly disappeared? Have tried a rescan but still not picking up. Film 4 is also not there. Very frustrating that I paying for something I cannot now watch. I live in Nottingham by the way and have also suffered from bbc 1 becoming Midlands as opposed to East Midlands.
Thanks
Martyn
