Nick & Mike: Thank you for your comments.

Like youselves, I am also a bit of a perfectionist (which drives my better half mad). My current Horizon meter seems to be showing that my SD reception is execellent, but in signal strength and quality. The only issue is whether or not my HD reception is optimal. But I don't see how I will be able to prove that without spending a fair amount of dosh getting a HD-T2 meter. The trouble being that once I've established the facts, the meter will be redundant.

The alternative is to get a TV engineer in, and I've been stung doing that before....

Tony: I really do think that rather than taking the in-depth analysis approach as to the possible causes of your complaint and maybe being tempted to spend no end of money as well as frustration in the process, that the reason for your problem would be discovered a lot quicker if you managed to borrow either an HD box or an HD capable (DVB-T2) TV and checked the results from your aerial system using one of these devices, because I have a sneaking suspicion that you are not really willing to consider the possibility that the problem could be caused by the card, and likewise are looking for reasons that excludes it, albeit I do accept that there is a very slight possibility that it might not be!

And with regards to the PC card, I do realise that issues existed between the WMC and the card, but I am referring to other aspects concerning comments seen made in various sources regarding the actual tuners performance including its ability to cope with an offset in the frequency of whatever its trying to tune in, as software wont necessarily help with that type difficulty any more than it does in a range of the older Vestel chassis Freeview PVR devices, with the results of a software upgrade in these devices being totally hit and miss, because the problem is more one of a hardware circuitry nature caused by a PLL oscillator with a semi rigid AFC range.

jb38: This strand really got going because I was wondering why WMC was reporting HD channels as having a signal quality of 60% when all of the SD channels were 100%.

I am committed to providing digital tv to all rooms in my house from a single source. This allows us to be able to watch our recorded tv programs from any room in the house as well as live HD tv without having to replace all of the televisions.

Based upon your suggestions, if there is a problem with the video cards, then I will just have to live with that until a better card comes out.

Hope this thread hasn't been a complete waste of your time and much appreciate your comments and those of other contributers.

Where is the Deptford self help relay located? What channels does it use?

Gareth: According to mb21, it is located at TQ374776.

This resolves to the junction with Creek Road and Deptford Church Street. Other than that, I haven't found any information online as to what channels and polarisation it uses.

Perhaps Ofcom could advise you.

Thanks Dave. I will investigate with a pocket DVB -T set next time I am over there.

Dave Lindsay, Gareth: Don't assume that the grid reference is accurate! All Ofcom's document says for the location is 'south-east London' and that it targets 100 households. Some of the grid references on MB21 are accurate, but only because someone has been out and found the site already (in which case it's probably been photographed).

The final Installer Newsletter for Crystal Palace (….pdf ) stated that Deptford was still active at the time of writing, but that they had not yet decided whether to apply for a digital licence.

It was listed as a transposer in Ofcom's guide, which means it uses different channels from those used by Crystal Palace. The other sort of relay is an Active Deflector, which uses the same channels.
