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 Caradon Hill (Cornwall, England) mast?

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?

Steve james:
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 ;)

Why does Caradon not broadcast Sony Movies Classic, ch. 50?
Is there any hope of a change in this?

Christopher Bryant: Sony Movies Classic is broadcast on the local TV multiplex, which is only available in areas where there is a local TV station, of which there are none in Devon or Cornwall. This will only change if Sony decide to pay more in order to broadcast the channel on a national multiplex with wider coverage.

Chris.SE: I hold an amateur radio licence, so I know about ducting. In this forum I avoid over-technical comments which might not be helpful to many enquirers.

It's not over-technical IF you explain it, best way by a link to explanations already provided by others (as Ive always done). That picture should be simple enough for everyone to understand.Just referring to high pressure makes people believe something is being hidden from them as they know there are many occasions when there's been high pressure but no problem with TV reception.
I'd suggest you look back at all the twitter comments to FreeviewAdvice around the New Year when "high pressure" was what people were told by Freeview. It lead to all sorts of conspiracy theories. At least the BBC mentioned Tropospheric Ducting at the time on their Reception Advice pages.
I believe in trying to explain the facts in as simple a way as possible, people learn things that way.

Michael: We are experiencing very poor TV signal daily between 1.00 pm and 3.00pm.
The signal is fine in the evening but useless around midday. This has been going on for nearly two weeks now. Any idea what is causing it?
