Thanks for the replies jb38 and Charles. I have tried to tune ch 33 manually and there is no signal on my Humax HD PVR. The reason I say needing a wideband aerial is a pain is because it is on the end of a long pole on a very high chimney! I have reached it in the past, but I really don't fancy it now, and it isn't worth paying an aerial installer just to get BBC Four HD.

Hi jb38, yes, I did do the test correctly on ch33, and it showed nothing at all. I also tried ch58, and after manually selecting DVB-T2 it showed 54% strength and 100% quality. I rechecked ch33, made sure I had selected DVB-T2, and it definitely shows nothing. I think I need a wideband aerial.
Thanks, Jon

Hi jb38,
Thanks for your persistence and suggestions; I have solved the problem, and the answer is very silly. I didn't blank my Humax, I borrowed an HD signal analyser so I could check the whole of my system from the aerial down. I connected the analyser in the loft, and it said 46dBuV on ch33 direct from the aerial, and gave a decent picture of BBC News HD. I wasn't expecting that!
The aerial goes to a 20dB loft amp, then a long downlead, a passive splitter under the ground floor then to an aerial socket in the living room. There was a huge signal loss in the living room, which was due to the socket. At first I thought the socket was faulty, and then I realised what I'd done. My excuse is that the socket is in an awkward position behind a cabinet, but it is a dual outlet socket (TV/FM) and I had put the plug into the FM hole! It passed enough signal for the higher channels to work, but not channel 33. Now I have 80% signal strength on ch49 and 70% on ch33.
I was convinced there was nothing wrong with my system, so it is only because of your prodding that I actually checked it properly.
Thanks for your help,
Jon

Nothing on the com7 multiplex (BBC Four HD etc) from Mendip is receivable by me in Bristol. Because it is on channel 33 a wideband aerial is probably required, which is a bit of a pain.
