Logomage: As you are only located at just over half a mile away from the 400 watts Bromsgrove relay transmitter, then unless there are any major obstacles in the way between you and it the signal you could be receiving might be at about an equivalent level to a person at about 4 or so miles away from a 25Kw transmitter, and so just purely for a test try using a set top aerial of the non powered type and give your equipment an auto-tune whilst using this, although this preferably done after having carried out a factory reset, or ignoring a factory reset if "first time tune" is an option.

Did you change your aerial to a wideband one ? some channels moved out of the old aerial banding.

Logomage: I would like to amend that said by myself, as I was looking at the Bromsgrove transmitters radiation pattern and see that its biased to favour the opposite direction from your own, and although you might well be located relatively close to the transmitter I also noticed a number of areas with small patches of trees between it and you, the combination of both these factors liable to result in somewhat less signal strength than would normally be expected, this making what mike fisher has said a good deal more important.
You should try a comparison signal check between Mux Ch23 (ITV) and Mux Ch47 (Film 4 etc) this done by going into your TV or boxes "manual" tuning menu and entering mux Ch23 but NOT pressing scan or search, because the signal level should be indicated, note it and then change the channel number to Ch47 and note it then compare these two, as these two represent the entire band that your aerial will be picking up.

Thanks guys for the info ...... we didn't change our aerial on digital switchover and it's a loft aerial which doesn't help ..... I'll do what you suggested jb38 and report back ... I'm beginning to think we need a good aerial man tho ... any suggestions?

Logomage: This might not be necessary provided that your aerial is still vertically mounted and is facing 231 degrees, you could of course trim the aerial up to a reasonable level of precision if you leave the signal check screen on your TV for reference purposes, although TV's or boxes that offer a quality indication as well as strength are always more accurate, as quality is more important than strength.
When you observe the signal level stay with it for at least 1 minute or so just to make sure that the indications seen don't dive downwards now and again, because if they dont and you are genuinely suffering from a weak signal then a booster would cure this by lifting it up so that it can be well clear of the cut off threshold.
Anyway give an update on results, as what you observe determines the course of action.

I live in Droitwich and for the last few days my YouView box has been unable to receive the Freeview HD channels from the Bromsgrove transmitter. Does anybody know what might be causing this? I have already tested this on a completely separate aerial and just get a patchy occasional signal using that. It seems as if the transmitter is running on reduced power.
Any help/sugeestions greatly appreciated. Tnx

Walter Ego: With regards to the problem you are referring to, no TX faults have been reported on the BBC's R/T investigation site nor according to DUK are there any planned engineering works taking place anywhere in the Central region, and so unless some fault has developed that has not as yet been reported (which I doubt if it has) I am inclined to feel that your problem is possibly caused by your receiver operating with a level of signal that's not really high enough above the cut off threshold for the equipment being used, the reason for no reception being that the signal (although still there) has now dipped under the level necessary to resolve a picture but though that the temporary aerial that you tested the box on is slightly better positioned than the one normally used, as the threshold levels referred to are quite tight between resolving a picture and not doing.
If your "You View" box has a manual tune facility then you should enter Bromsgrove's HD service on Ch30 but do NOT press search or scan, because most equipment will indicate the level that the signal is being received at as soon as the mux channel number has been entered, make a note of whatever it is then change the channel number to BBC Ch26 likewise noting its level, then using the same procedure again enter Ch23 (ITV) then compare its level with the other two as that will give an idea of what's causing your difficulty, because if the signals are generally all received on the low side then a booster would help the situation provided that the drop out is not being caused by the quality diving, as virtually nothing helps in that type of situation except by experimenting with alternative aerial positions starting a few feet to the left or right of its present position.
By the way I noticed that Sutton Coldfield as well as Ridge Hill are both indicating as being capable of proving a better signal than that from the Bromsgrove transmitter, have you previously tested out reception from either station? as the signal from Bromsgrove appears to suffer from a blockage in its path at about 1 mile or so from the Droitwich Post office I used as a test code by being unaware of your own.

Walter Ego: By the way please ignore the latter paragraph in my reply as I have now obtained the correct post code, this indicating a clearer path for the signal from Bromsgrove free of the obstruction referred to, at least anyway as far as anything of a hill nature is concerned as these terrain indicators do not take account of trees nor any man made objects no matter how large they may be.

jb38 many, many thanks for your very detailed reply which is greatly appreciated.
My HD reception seems to have returned to normal now so I'll keep your advice on file for future reference.
I noticed that my YouView box was running quite hot last night so it may be an intermittent fault developing with that. The HD channel signal readings yesterday were c. 48% for strength and c. 54% for quality but now, although the strength is still only about 50% the quality reading has reverted to 100% which is fine enough for my gear to work properly!
My normal aerial is located in the loft with an 8 way powered booster distributing signals to various rooms. This arrangement was often a bit "iffy" before switchover but I've had no signal problems at all since then (until this week). My reserve aerial (without booster) is on the chimney and is aligned to the Sutton signal.
Cheers for now,
Wal

Walter Ego: Thanks for the update / explanation regarding your aerial arrangements which by the way I found rather interesting, insomuch that I noticed the signal from Sutton.C @ 27mls / 30 degrees is nearly in the same line as Bromsgrove @ 7.5mls / 27 degrees, and although you have mentioned that the quality had increased in level and which is now resulting in satisfactory reception, however I don't really feel that the signal strength reported is really running with a sufficiently high enough level of safety margin above that of the cut off threshold previously referred to, and so this should be kept in mind should any problems arise.
That said, I do accept that this is possibly because that the "You View" box you are using is fitted with a slightly insensitive tuner, older BT vision boxes suffering from this problem.
However, should the HD signal from Bromsgrove take another dive at some point in time (as I suspect that it will) then as well as immediately carrying out a signal test on Bromsgrove's HD channel, as the signal level should still be indicated even although no picture is seen, I would also be interested to know the result if you carried out the "manual" tune test procedure that I previously described (without pressing scan) but on Suttons HD Ch40 "without changing aerials", albeit of course that the polarity of the aerial used for Bromsgrove is incorrect for Sutton.C, the latter radiating on horizontal polarity.
As far as your "You View" box is concerned, if at all possible without causing chaos to your set up I would like to know the model number of box that you are referring to, this being for purposes of checking the technical manual for same to see if any defects have been notified as yet, my curiosity being triggered by what you have mentioned about it being inclined to run on the hot side, something not particularly conducive to the life of electrolytic capacitors, the info requested being basically for my notebook and not for any other purpose.
Anyway you could maybe keep that said in mind for the future.
