Look at the blue box at the bottom of your posting titled 'digitaluk trade' (http://www.digitaluk.co.uk/coveragechecker/main/trade/SO40+8DZ/NA/0/) and then look at the expected reception from Rowridge.
That shows that currently your location gets variable coverage of the SDN, ARQA, COM7 and COM8 multiplexes, even though you are only 28km from the transmitter. It also shows that from April next year reception of COM7 and COM8 is expected to improve. Further, it shows that COM7 and COM8 use channels 55 and 56 - which is way outside the reception ability of any Group A aerial. So you need a good wideband aerial fitted. So go ahead and talk more firmy with the Freeview service on 0808 100 0288.

Please please help me get channel 108 for Aljazeera.
Since the update this channel is lost but its states I'm still supposed to receive it?!!
I can't keep resetting my box and retuning everyday it's ridiculous.
Help x karen

Miss karen alison young: Continuously resetting/retuning isn't going to suddenly make a channel appear if it didn't the first couple of times. You most likely have a Group A aerial which isn't designed to receive the higher frequencies which the COM7 mux carrying Al Jazeera HD has moved to. If you don't have satellite or cable you may be eligible to have a replacement wideband aerial fitted free of charge, which can be arranged by contacting the Freeview Advice Line (see link below).

Well this is interesting. Looks like the power level has been increased on ch55 (COM7) from Rowridge. As I posted earlier, COM7 disappeared here in SO24 when it moved to ch55. This was no aerial problem as I had a new group T aerial and ch56 (com8) comes in at 90% signal strength, while ch55 was showing zero.
Checking ch55 again yesterday evening and lo and behold it's there with a signal strength of 86/90% and signal quality of ~70%. Indeed, better than the old ch31 and very similar to the COM8 figure. I have changed nothing here, so the improvement must be upstream.
If someone was listening and upped the power level or changed the directional mask, then a big thank you.

It is quite possible that you had too much signal, 90% or more is too high - the ideal being between 60% and 85%. The effect of too much signal is to overload the tuner so it then claims there is no signal. The atmosphere absorbs some signal and that varies with the humidity of the air, amongst other factors. So it would seem that the signal level has actually reduced as there have been no increases nor decreases in the transmitter output power.

I saw this too, suddenly this morning BBC News HD and the various other channels that I have lost due to having a group A aerial for Rowridge.
But now the wedding is over, they've all gone again. Was this just for the wedding?
I've got the aerial people (via Freeview complaints) coming on 9/6. I was going to stand them down but no such luck.

MikeP:
I understand your point, but I doubt whether this is the case here. I suspect that the definition of "Signal Strength" varies between different TVs - 100% of what? BER is probably a better comparative measure.
On PSB1, 2 and 3, my TV reports a signal strength of ~98% but 0 BER. So I interpret that as a good quality signal and no more. I don't have a masthead amp and we are in a fringe area and so I doubt whether 98% signal strength means anything more than that. If I was seeing the same signal strength but a BER >0 then over-modulation may be taking place - but I have never seen that.
COM7 and COM8 are showing a BER of typically ~500 but with the high pressure this has gone up to ~1500 and last night both went over the 2K mark (and fell off the digital cliff). So all is not wonderful. Ch31 and Ch37 were more stable than this and I suspect that the higher frequency is to blame - and possibly Hannington.
The main point of my original post is that suddenly COM7 was there when it was not last week. Now it is showing "signal strength" and BER similar to COM8. So what changed?

You miss the point. Too much signal being fed into the tuner caues it to fail, hence you get reports of zero signal or weak signal. Supplying 98% will definitely detrimentally affect how your TV tuner works. So you need to reduce it to below a reported 85%.
The only thing that changed is the weather patterns in the area. There has been no change to the transmitter.

Although the Transmitter maps were very useful, they are now appear to be much out of date and I would enquire if these are to be brought up to date to reflect current position. For example,
On the Rowridge data, UHF Channel 37 includes CBS America (TV94) which I used to be able to receive prior to the latest shakeup, but it is no longer there and I have no idea as to where it has gone. I cannot get any response from CBS America themselves. Even an auto tune fails to find it.

Norman Langridge: PBS America (not CBS) is broadcast on the COM8 multiplex which has moved to UHF channel 56 at Rowridge. If you cannot restore this and any other missing channels by manual tuning then you are most likely using a Group A aerial which is not designed to receive the higher part of the UHF band. If you don't have satellite or cable you may be eligible to have a replacement wideband aerial fitted free of charge, which can be arranged by contacting the Freeview Advice Line (see link below).
