buckers24.Yes.The 71% strength denotes you do have the strength of the signal concerned,but the 0% quality does certainly denote you do not have the quality of the signal as such hence no channels.To receive any signal as such yer signal quality must be 100%,99% or less does lead to pixellation,picture break ups and upon 0% signal quality total loss of reception,the classic "No signal" mode.However a signal strength of 73% or 75%+ denotes too much signal,this too in excess can lead to pixellation,picture break ups and even loss of reception as well.

Dave, Tacolneston does not do it's final switch until 23rd Nov - I'm not sure if Sudbury's pathetically lower power commercial Mux's go up then though? On the same day, Sandy heath finally ends the use of C67 & moves PICK & all down to C51 I think. not sure if that will then be at full power then. Aquiva's policy seems to be just so long as the BBC, ITV, C4 & 5 signals get out, the rest get Pot-luck!

Correction, Aquiva A currently on C67, moves to C52 (not 51) on Wed 23rd Nov.

buckers24 - if you have a 9200T, try a firmware update as older firmwares don't like a mixture of transmission modes (which is what we have on Sudbury)

I too had trouble receiving ArqB after the 16-11-2011 change from UHF 50 to UHF 63. I was getting 50% signal but only 10% quality.
Annoyingly, I had Freecycled my amplifier after I found I could receive all 5 SD muxes perfectly following the 20-7-2011 changes - so I either had to buy a new one or wait for the 27-6-2012 power up of all 3 COM muxes to 100kW.
A £4.50 ebay purchase of a new Philex amplifier improved my UHF 63 reception so I'm now getting 90% signal and 70% Quality - no pixelation or sound pops at all.

Before work at Sudbury on 16th November I had signals fro the group of programmes including yesterday/viva/film4/4music/itv4 etc
Today they are gone - I have followed your instructions for single frequency interference but with no effect.
Will I get them back ? Why have they gone?
Will FREEview mean even further expense as already need to spend a great deal to record freeview programmes on modern Tv's
Info will be appreciated

Heinz : I posted elsewhere (on the Sudbury Re-tune thread) about also getting the channels back when I re-instated my old signal amp. This despite perceived wisdom on here (and other Digital TV sites/forums) being that they don't help with digital channels! A TV engineer on that thread confirmed that, in his experience, signal amps DO help marginal digital channels.

Dale: I think that any statement that amplifiers "don't help" are made in respect of the way that they are often (mis)used.
That is not to say that there aren't proper uses where they are of benefit.

Channel 54 as well as 63 up the pictures, so to speak. Must be the fog currently afflicting the Ipswich area. This whole digital enterprise is a complete fiasco. bearing in mind the cost of new cabling, receiving equipment and wideband aerial equipment.
Pressure needs to be brought on the people responsible for all this retuning with regard to the inadequate transmission and frequency levels of certain channels.

I wouldn't go out and buy a masthead amplifier no signal means no signal. I have one to compensate for the attenuation of the aerial lead before I get to my distribution amp. I've got zilch on channel 63 at the masthead so there is nothing to boost.
