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.

Just had a 20 min talk with a very nice man from the BBC. He says that he is going to look into the ch 53 problem, but if anyone else has problems, please report it to the reception desk on 03700 100 123. The more people who phone in the better. It will enable the BBC reception team to localise the problem better.

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!

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.

Hi Jon. Yeah I spent half an hour with the engineer this morning doing monitoring duty and the problem was found to be one of the exciters at the Dover transmitter. Channel 53 is now back on and they are investigating what happened. Thanks to all who helped in this problem. By the way. Channel 47 is the Sudbury transmitter and transmits Anglia television programs. Points East etc.

Margate
Judging by the number of comments on here, there is a big problem with mux BBC B in the cliftonville area of Margate. I too lost my HD channels altogether (No Signal at all) and so far nobody has come up with any explanations. All other muxes are fine at about 90% signal and excellent quality. Where would we get someone to look into this problem as it has been going on for about 2 weeks now. It was previously perfect reception.
