Lost BBC4 HD and BBC News HD (and all channels between Freeview 106 and 202).
Problem started shortly after midnight. Have retuned twice - as worked was appafrtently scheduled.
No joy at all. 106-201 still missing.

Freeview 106-201 all gone.
Crystal Palace had engineering work last night apparently.
No BBC News HD No BBC4 No Al Jazeera despite 2 retunes
And no information from Freeview - is this supposed to be a transparent process?

I'm SW9 8SE but live next to a railway viaduct at roof-height. My signl was perfect with a large Band A yagi mounted in the loft - but with the migration of Muxes 7 & 8 to Ch 55/56 I have problems. Wideband aerials seem to cannot get me a good enough signal at the low frequency and high frequency end of the band to avoid picture breakup and loss of sound spasmodically when trains pass.

What I also wanted to comment on was your station cahrt above. Very helpful - but Channel 40 is now Sony Crime, and according to my TV is going out on Channel 22 482 MHz (presumably Freeview Channel 40 was re-allocated afer yor chart was compiled).

MikeP: Thank you for your recommendations, which are obviously correct, though do not take into account living in a 4 storey terraced house in a conservation area in inner London.

I before I go for Freesat I think I will try an 18 element yagi to try to up the signal enough to overcome the issue. Funnily enough 2 weeks back the Freeview engineers fitted a 28 element Log periodic which got rid of the reflections on my upstairs TV, but I completely lost reception on Channels 106-113 on the downstairs TV.

Reverting to my original 10 element yagi brought all channels back, but obviously also brought back the picture and sound glitches with the trains on the viaduct.

Can't say why, but over the last couple of days signal in my location seems a bit lower than normal - getting interfeence from passing trains particulalrly on Sky News 233, which I have not had for a long time.

I would never have know this if it wasn't poster here.
Radio Times has True Entertainment as channel 48 but True Movies is not listed.
My set did not need a retune to get these channels.

Huw Radley: I think your Crystal Palace signal may be borderline. So if something like adverse weather conditions or some unexplained power reduction at Arqiva occurs your DTV drops out until the signal level is restored to a level the TV can use.
I have had similar problems. I live only 3 miles from Crystal Palace, but my aerial is in the loft. Heavy rain on the roof, verdant leafing on trees over the road or even gradual creeping out of alignment of the aerial itself can take out weaker channels - especially the COM7 and COM8 HF ones for BBC News HD etc, not to mention those interesting channels like PBS America and Smithsonian.
If your aerial if old (like from 2008 or something) this would certainly account for lake of BBC News HD etc as those channels now need Band T aerial, not Band A as someone said upthread.

Huw Radley : Agree with MikeP - your aerial is not suitable for Freeview Channels 91-99, 101-113.
It probably works OK with other channels, including BBC One - Channel 5 HD.

What interests me in your comment was this "there are 6 Panasonic TVs here".
Does this mean you have some sort of splitter running one aerial into up to six TVs?
If so, given you are on the fringe of the Crystal Palace reception area, have you consided upgrading your splitter (if you do indeed have one)?
