Prof M.:
As StevensOnln1 has mentioned COM7 has not yet been switched off, it remains on 25 of the main transmitters.
The Nov.2020 date further up the page is sonewhat misleading but if you followed the " more" link it takes you to a thread with more detail, however you do need to go back a couple of pages to get the correct overview.
See this post https://ukfree.tv/extras/…2572 to start.
The only thing that can be added to that is that EE bought those centre frequencies and could give 3 months notice to use them but that is on the assumption they have the SDL transmitter equipment available to install and operate (and of course suitable user handsets have to be available to use SDL on 700MHz).

Tim Noakes:
As you haven't given a full postcode or haven't said which transmitter you receive, we can't provide any constructive advice other than to say look at your own aerial and see if it appears intact and is still pointing the correct way (compare to neighbours). Also check your downlead looks undamaged and isn't flapping in the wind.
Most transmitters are operating normally, (Bilsdale being the exception), a few are undergoing Planned Engineering which doesn't usually affect reception for lengthy periods.

Chissey boy:
As StevensOnln1 has said, have you looked at which way your aerial is pointing?
This is quite interesting because depending on where you are within your postcode reception is very different. At some points you can also pick up 2 relay transmitters as well as Mendip and Oxford but reception can be quite variable.
There is one relay very close (1km) - called Chiseldon - which is a relay of Mendip and it's in virtually the same direction as Oxford from some points in the postcode although vertical polarisation.
So rather than go through all the possible combinations, if you post back with the direction you aerial is pointing - fractionally E of NE (for Oxford) bearing 51 degrees or roughly WSW bearing 243 degrees (for Mendip) and both of those with the rods (or squashed Xs) horizontal. Also indicate if you are towards the North end, South end, or roughly in the middle of your postcode.
The other information which will help is exactly which UHF channels you are tuned to for every multiplex. Look in your TV's tuning section where you should find this.

Chissey boy:
Oh, one other very important bit of information I forgot to ask, roughly how old is your aerial?
Also can you get BBC4 HD on 106 and BBC News HD on 107?

Paula Farrell:
The DL6 postal code area is quite large and with the nature of the terrain in North Yorks we need a full postcode to look at predicted reception. We'll also need to know which way (rough compass bearing) your aerial is pointing as at one random area I checked you could receive may 5 different transmitters with bearings roughly NNW, NE, Fractionally S of E, ESE, or SSW. Also which region you normally get - Yorkshire or Tyne Tees.
Having said all that, I can't find any faults currently listed for any of those transmitters but 2 of the transmitters are on Planned Engineering so brief interruptions are possible. If you happened to retune whilst you had no signal for the BBC channels it will probably have just cleared the correct tuning. Are you missing the HD channels 101-105 as well or just the SD ones - 1,2, 9 etc.?

Roland:
Hi. Waltham is on Planned Engineering this week (again!) which may well have a bearing on this, but if you provide a full postcode we can look at that predicted reception and may be able to offer further advice.

HF:
There is currently some moderate temperature inversion/tropospheric ducting conditions affecting large parts of the UK and these weather conditions can disrupt reception for brief or longer periods. The conditions are predicted to last for a few days.
This is what appears to have affected your reception -
BBC report - Morfa Nefyn - Freeview: Weather conditions may be affecting your reception from 17 Dec 18:50 until 17 Dec 19:09. .
Conditions can change by the second, minute, hour and not all multiplexes may be affected or not even at the same time if more than one. You may have lost your signal and it may have returned several times.
I hope you didn't retune whilst you had no signal as this will likely have just cleared your correct tuning and you could even get tuned to weak interfering signals which eventually disappear.

High pressure impacting TV and Radio services across parts of the UK
Some viewers across parts of the UK might experience short-term interference to BBC television and radio service. This is being caused by a zone of high pressure, which causes problems to the links between transmitters and it also increases interfering signals in specific areas, which results in poor reception.
The conditions can move and change which makes it difficult to know where it will hit next. You can check if the problem is impacting your local transmitter using the transmitter checker tool. If there are no faults displayed it is possible the problem is impacting your radio or television system directly.
The majority of the BBC's transmissions are not affected by this period of interference, as the BBC's networks are engineered to be generally very robust. Television viewers may experience slight occasional pixelation or break-up or loss of service. Radio listeners may experience break-up of their services. Cable and satellite services are not affected.
At these times, there is nothing you can do but wait until the weather changes. You should not re-tune your television or radio when this happens.
If you have retuned your TV and continue to have problems with missing channels, or reception problems, as a result of the high pressure, you'll have to retune again once the weather has cleared.
More information explaining why these weather conditions cause problems can be found here -

Lib. :
Hi. Posts don't always appear immediately which can be a bit frustrating if you don't realise that.
Your loss of signal is the weather conditions I'm afraid.
There is currently some moderate to strong temperature inversion/tropospheric ducting conditions affecting large parts of the UK and these weather conditions can disrupt reception for brief or longer periods. The conditions are predicted to last for a few days.
Conditions can change by the second, minute, hour and not all multiplexes may be affected or not even at the same time if more than one. You may have lost your signal and it may have returned several times.

The link in the 2nd one isn't as good an explanation as the.jpg link I've posted.
I hope you can watch Strictly on iPlayer.

Nigel Seaman:
Which stations are you having problems with?
The BBC aren't reporting any faults on their main multiplexes from Wrotham, Bluebell Hill or Benfleet or on any commercial multiplexes carrying BBC Local stations from Benfleet or Maitland House.
It's almost impossible to find fault reports for the main commercial D1 and SDL National muliplexes, for you probably coming from Bluebell Hill, Wrotham and Benfleet and maybe Danbury.
Bluebell Hill is the only transmitter that's had Planned Engineering listed for Digital TV so whether that's had any effect on DAB hasn't been listed.
