The symbol shows the location of the Waltham (Leicestershire, England) transmitter which serves 770,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Waltham (Leicestershire, England) mast?

Ian from notts: The COFDM signals used for the digital TV are much less prone to problems caused by Tropospheric Ducting (aka "The Inversion Effect").
However, the prediction for "excellent" Freeview reception is "99%" - which still allows for 90 hours a year of problems.
Looking at the forecast - Tropospheric Ducting Forecast for VHF & UHF Radio & TV it seems quite likely that the strong signals used in the Netherlands could quite easliy make it to East Anglia, for example.
DVB-T receivers can (by use of the "guard interval") reject a weak, distant signal most of the time, but Tropospheric Ducting can sometimes (the 1%) dump strong distant signals where they are not wanted.

The guard interval has no function in rejecting different transmissions on the same channel as your wanted one. It's only useful wrt multipath reception of the same programme, either from a single transmitter or in an SFN.
The protection from uncorrelated interference comes from the error-correction, interleaving etc.

Since other people were reporting loss of signal it seems likely that the distant transmissions were just being picked up instead where the aerial was suitably pointed.

Anyone got a further update on WMC? My partner is getting close to killing me if I can't find away of getting it fixed.
I have emailed and spoken to operator of the mast and they're reporting no issues; however if you can see pick up signal from another mast okay, how can we be having issues with this one?

The WMC issue is very real, as is the likelihood of a possible two deaths as a result of it (much like Darren I am living in fear of my other half because I can't fix this).
The seems to be lots of discussion about fixes and there not being a problem but it is as simple as this in my eyes:
a) before the retune all channels working perfectly
b) post the retune itv, channel 5 etc don't exist
The very unreasonable stance taken by the broadcaster is that WMC doesn't have a freeview logo is not helpful. Should I be questioning if I should pay for my TV licence in full because many channels are not available, i think not.
The fact that I can get these channels via mediaportal is what told me that this is a wmc issue but Microsoft don't acknowledge that there is a problem either, highlighting that if it worked before then it is the broadcasters fault.
Please can someone out there do something to resolve this before both Darren and I are snuffed out by respective other halves.

I have a response to my email of 10 July. It's similar to John's as reported on 8 July. Mast operator reports no issues, info passed to infrastructure team, will contact me again if they have anything to say. Ho hum.
There has been a change; I've quoted details.
It might be within their specs and I can live with it. Good luck.

jb38,
Thank-you for your comments. There really is so much to learn about broadcasting.
I am not in a position to realign our aerial to Belmont, unfortunately. I had considered asking an extended family member to realign it to Sutton Coldfield, but after I mentioned it in passing they all disappeared.
I take what you say about negative offset frequencies. If that is the case, I believe it has always been the case (recent past anyway). PSB2 on Waltham was unaffected by the 4G retune issue as far as I am aware. It was PSB1 mux that was moved, necessitating the retune on 29 May last.
Here no unusual reception difficulties were noticed until 16 June when ITV failed. Subsequently I noted that Channel5, E4, More 4 and such (but not Channel4 or Channel4+1) showed only black screens.
It appears that ITV1, ITV+1 and Channel5 are back here this evening. How long for? Let's hope...

It's fixed. The mysterious extra video streams in the ITV/CH4/CH5 mux have gone away. Good for the 'infrastructure team'!
