> Seem to have lost some HD channels after recent retune. 113, 107 etc.

Those services are in the COM7 multiplex, which was completely off-air from Tacolneston from around lunchtime Friday until about 10 a.m. this morning. If you retuned in that period, it explains their loss. Try retuning again now the transmission has been restored.

Still no joy for me with COM7 and COM8 through my BT Youview box.

However no probems at all with them with the aerial plugged directly into the TV.

The readings from the TV for BBC1 HD is 95% quality 100% signal.

The readings from the TV for BBC News HD is 62% quality 100% signal.

The readings for BBC1 HD from Youview is 100% quality 96% signal.

Cannot supply figures for BBC News HD through Youview as it won't tune in.

I have another aerial for the kitchen that used to point at Tacolneston but now points to Sudbury. This was in the low power days and Sudbury was very patchy. In comparison Tacolneston was good. The quality and signal levels in those days were much lower than todays and the picture did get interrupted by the fridge motor. The point I'm making is, I could always pick something up despite much lower signal.

The one thing that I notice when I call up BBC News HD is it always has a slight delay before the picture comes on. Thereafter it is fine. I think these Youview boxes don't give their tuner enough time to lock on to the channel. This is something that could be easily resolved with a manual tuning option.

DJB: If you have 100% signal strength you may be overloading the tuner with too much signal. Try fitting an attenuator to reduce the signal strength.

DJB .I have the same situation with a youview box compared to the tv. I believe that the box is just less sensitive than the tv . Its not surprising really knowing that COM7 and COM8 were around 1/3 power of the other multiplexes . They are now a bit less than 1/5 power. We need a bit more amplification or an aerial having greater sensitivity at the COM7 8 frequencies . Note there is a limit to how powerful an amplifier to use because there is such a thing as too much amplification..

Hrdy and DJB:

In both your cases it could be that you have too much signal, as suggested by StevensOnln1. It is often the case that different equipment responds differently when fed too much signal. So I concur with the suggestion to reduce the signal strengths - it need to be between 60% and 85% for best results.

I agree that if DJB is seeing 100% on com7 or 8 amplification might be too high . In my case on the youview box the level fluctuates between 44% and zero on com8 . Its zero on com7. Its hard to read strength on the tv but the picture is usually fine with no pixelating.

Hardy: I've just been in the loft and placed a 10db attenuator on the distribution side of the amplifier.

On the TV BBC News HD was still available. BBC1 HD and ITV HD had no picture and reported low signal. After a retune they came back and BBC News HD was still there. The TV is being fed from the out line of the Youview box.

I retuned the Youview box and there was no change. BBC News HD still missing. The same 130 channels reported prior to introducing the attenuator.

The final test will be to put the youview box and a TV in the loft and feed it direct from the aerial before the amplifier is involved. I have to do this prior to the soaps starting otherwise I'm dead.

HARDY: This is so frustrating.
In the loft, TV tunes in to everything.

First attempt at the youview box I got Com 8 not Com 7. On the second attempt I got both.
The youview box signal indicator gave a quality reading of about 40 and 20 respectively. The box tuned into 170+ channels. I get 130 downstairs.

Back downstairs and Com 8 and 7 are blank. In addition BBC1 HD etc all reported signal problems. Did a retune and now they are back. Looks like the box locked on to a weaker but viewable mux for BBC1 HD upstairs but that mux is unreachable downstairs.

No problems at all with the channels viewed through the TV.

Youview need to produce a box with a more sensitive tuner.

DJB looking at your post code it looks like you have a difficult situation . ie you are quite close to Sudbury so you should be able to get all its channels reliably with no amplifier . To get com7 and 8 you need to tune to Tacolneston but that will require an amplifier . There is also the possibility of some small signal from crystal palace ,Dover and a local relay!! In such a situation I think a careful choice of aerial (or even aerials !) and type of amplifier would need to be made . It could be that a wideband amplifier like you have cant cope with such a mixture of strong and weak signals . I think the ideal set up would be a non- amplified aerial pointed at Sudbury combined with an amplified aerial pointed at Tacolneston. But the amplifier should be a tuned type only covering UHF 50 to 58. (a relatively expensive set up) The Youview box maybe having trouble with the mixed signals not just a lack of sensitivity . My set up is almost identical to yours but in this location its just weak signal and continental interference that is the problem so I have gone for Freesat .

Hardy: I'm going to have to admit defeat on this one. I only went down the amplifier route as I had missed an episode of Homeland a few months ago and I wanted to watch the replay in HD on C4/7. I had hoped the retune last week would have brought those channels in for me. Ho hum.
