Roger Palmer:
There are unusually high levels of "Tropospheric propagation" at present, often associated with High Pressure weather systems.
These levels of propagation are unusual at this time of year - they cause signals from more distant transmitters to travel a lot further than normal. It is currently affecting different parts of the country by varying degrees and signals can change by the second or remain stable for much longer periods.
In the old "analogue" days there was a lot of talk about "continental" interference often in the summer months, but the interference can come from transmitters anywhere in the UK or Europe and even further afield. At the moment some people are getting DAB radio from the Netherlands and FM Radio from France as well as the interference to DTV.
It is predicted to continue for a couple more days, and you are advise NOT to retune as you will likely lose the correct tuning that you had. The "propagation" can be very frequency dependent, and it can only affected one frequency or several, but it can/will be different for others.
People will however have noticed the unusually mild weather which the Met office is referring to as a "Foehn effect" but it's not helpful that it seems none of the major broadcasters are making any reference to the interference being caused to TV and Radio reception! So it's no surprise that people wonder what is going on and think there is a transmitter problem.
For those that have retuned and lost correct tuning, you will have to try again and it could be hit and miss whilst the unusual propagation continues. If you are able to do a manual tune for the correct UHF channels, you may still receive interference or the wrong programmes.

In addition to it affecting TV reception, it is also affecting DAN signals as well, causing either loss of some signals or fading of those. In either case DO NOT RETUNE, as Chris.WE says.

PL20 6QU and neighbours have had intermittent blackouts since 29th December. I see that there is no work being carried out at Caradon but a lot in our village are being affected??

For the last few days at around 6pm I'm getting nothing on all channels (mix) except 21 and 27 where I seem to be able to get all programs. What's going on?

I assume you mean all the programmes on the SDN/COM4 and ArqB/COM6 multiplexes (see Channel listings | Freeview )
How long does this last for?
I can't see any reports from the BBC about problems with their transmissions on Caradon Hill or anything from Freeview either.
Have you changed anything lately, or had any new equipment (including electric equipment) which might operate at this time?
It would be a good idea to check all your coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. Flyleads are a common problem, try swapping/changing them. See what signal strengths and quality you are getting for those multiplexes shown in your TV's tuning section. Also check that your downlead looks undamaged (especially if it is old) and that your aerial seems intact and pointing in the correct direction.
Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.
Also check you don't have any HDMI cables near aerial leads and that they are all seated correctly.

As a corollary to Chris' comprehensive suggestions, it is worth noting that high pressure weather systems can affect propagation, and also cause interference from other transmitters - even from France. This has been observed,for example, on transmissions from Huntshaw Cross and Caradon.

To be a bit more technical, it's not just high pressure by itself, it's what sometimes can go with it - tropospheric ducting - https://www.bbc.co.uk/rec….jpg
I don't recall what the weather was doing mid-February ;)
