col stjj: With regards to your HD reception problem, in your August 11th @ 11.25am posting you reported the signal strength being indicated on the Huawei box as 60% and with a 100% quality, could you confirm that this was with reference to that obtained from Ch53?
If though it was, then the aspect that puzzles me is the reason for the screen being blank "unless" being caused by a fault within the box, because in practically all cases where a reception problem is being caused by a transmission fault, or indeed as a result of co-channel interference and something which cannot be completely discounted in your area, then the signal "quality" is always affected as witnessed by erratic quality indications being seen, i.e: constantly diving downwards, something which if the query I made in the first paragraph is confirmed is something which in your case has not been happening.
As far as the problem being widespread is concerned, apart from Dave G and yourself I cant say I have noticed anyone else complaining of an HD problem, albeit of course the that the HD transmitter was recently broadcasting programmes intended for another region, that being more of programme feed to the transmitter problem rather than an actual RF signal issue.
Another point that I would like if you could clarify is concerning your other Samsung TV, insomuch were you previously able to receive HD on it before the problem struck the YouView box? it would also be of assistance if the model number of this device was known.

Hi jb38, Thanks for your reply.I can confirm that the TV connected to the Huawei box was showing 60% signal strength and 100% signal quality on most channels. however C53 is not being received at all even after numerous resets & re-tunes. I`m thinking that as this affects my other TV then maybe the you view box is not the source of the problem
Ref the second TV, this was previously receiving HD channels with no issues, this TV has freeview HD built in and is not connected to the you view box, the same problem affected this TV as well ,this could also receive all other channels except C53, its like there is no signal for C53.

hi col stjj. My TV is an HD tecnika set. It had no problems until the last couple of weeks. Signal on ch 53 was 80% plus as were all the other muxes. Now ch 53 is totally NO signal (0%) and none of the other muxes have changed (85 to 90%) It is very strange. Several of my neighbours that I have asked have the same problem.

UPDATE. I can receive HD from Sudbury on ch 47 with no problems except for the occasional dropout so it is not the set, got to be reception,

Just had a 20 min talk with a very nice man from the BBC. He is going to look into the ch 53 problem, but if anyone else has problems, please report them to the BBC reception desk on 03700 100 123. The more people who phone in the better as they can localise the problem more efficiently.

Dave G: Purely out of curiosity, when you report no signal being received from your Dover facing aerial does this refer to that obtained by carrying out an auto-tune? because if so then that message does not necessarily indicate that absolutely no signal at all is being received but possibly one that is under the level required by your receiver to decode, hence no picture.
Although this is neither here nor there to a viewer who is unable to obtain a picture, but a proper test of whether a signal is there or not is achieved by going into the tuning menu / manual tune and entering Ch53 but NOT being followed by pressing search or scan, as this procedure will on most equipment cause the tuner to act like a form of signal strength meter devoid of reception cut off thresholds thereby giving an indication of very low signal levels.
Some TV's or boxes have rather restrictive menu systems that may not allow this procedure to be carried out, but should yours not be one of those types then I would be interested in the result.
The other aspect that somewhat puzzles me is that both Dover and Margate's HD service operates on Ch53, and when considering the fact that in your case the Margate 200 watts transmitter is located at only 1 mile or so away from you then I find it somewhat strange that you are unable to receive it from either source, although the result of the aforementioned manual tune signal test procedure might give some clues.
By the way, if you can receive Ch47 from Sudbury @ 50miles / 324 degrees then that's with your aerial being approximately 55 degrees out from reverse pick up "if" its facing Dover.

Thanks jb 38. I take on board all your comments. I am a retired telecomms technician. so I probably tend to think that everybody understands me and I gloss over some important points. Please bear with me.
My tv on manual tune with channel 53 selected (730 MHz) therefore using it as a signal strength meter shows 0% signal. This is before I even try to scan for programs. The scan process will not decode stations below about 55% signal strength. At this level the signal quality (A measure of the decoding probability I presume) drops from poor to none.
All my muxes apart from channel 53 are showing between 80 and 95% signal strength and very good signal quality. Channel 53 on the other hand displays 0% signal and none signal quality.
As far as the aerial alignment, I have not measured the angles, but just assumed it is on the back lobe.
The Margate transmitter is on a single frequency network with Dover and as such should augment the Dover signal. Historically, the Margate transmitter was just to fill in a "hole" in the valley at Dane Valley and was not receivable where I live. It has now changed both frequencies and polarization to suit the SFN. So virtually everyone here is on the Dover transmitter. Before the BBC B mux disappeared, I was getting ch 53 at about 80% signal strength. Something has happened about 2 weeks ago that has affected just 730 MHz reception. Very strange!

Dave G / col stjj: Thanks for the update on the situation with regards to my Ch53 query, zero signal being indicated on the pre search (or scan) manual tune entry verifying that it isn't just the case of a signal under the reception threshold problem, this introducing an air of mystery into the situation as it could even indicate that the problem is being caused by a TX panel misalignment (tilt) having occurred on the Dover mast and something which would only affect the signal being radiated in a particular direction, and of course if this was the case then its not surprising both of you are affected as there is only 3 degrees of a difference between your locations.
The reason I am inclined to think along these lines is due to the fact that I haven't as yet noticed anyone else complaining of this problem, although I do admit not to having had the time to troll though all of the postings made, however should anyone else make complaint then provided that they do not withhold their post code I will be eager to check their angle in relation to the transmitter.

hi jb38, I had a call from the BBC this morning. They are now sending out engineers to check both the Dover and Margate transmitters and masts. They will check the alignment of the tx panels and do full checks. Hopefully we should have ch 53 back soon. Hooray! I have to say that the BBC are being extremely helpful.

UPDATE:
Ch 53 in Margate is now back on. It was one of the "exciters" at the Dover transmitter. Now the engineers are investigating what happened.
Many thanks to all who helped to get this solved.
