The symbol shows the location of the Caradon Hill (Cornwall, England) transmitter which serves 180,000 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 Caradon Hill (Cornwall, England) mast?

Without a full postcode to do any more detailed checks, if it is Caradon Hill you receive, it's not listed for Planned Engineering which might have been a possible cause.
If the problem is occuring at exactly the same time each day then this could be some form of interference.
Have you made any changes to your installation recently? Are you (or possibly your neighbours) using any specific electric equipment at these times?
It's probably worth checking that all your coax connections and flyleads etc don't have any breaks or corrosion and that your aerial still looks intact and is pointing in the correct direction.

Hello,
I am used to having a few days of poor reception periodically over a year. I live at the bottom of a valley and reception can, on occasion, be difficult. I use the Mevagissey repeater for terrestrial TV. However, this year and specifically in the last 6 months, reception has been consistently very poor. Interestingly the BBC channels are first to break up and ITV channels the last to fail if indeed they fail at all.
I have had a full review of my aerial installation by a professional installer and they could find no problem with the equipment and had no better or more up to date aerial to offer that would improve things. Coming from a technical background I can only conclude that since nothing has changed at my end and that the equipment I have is operating correctly either there is a new obstruction in the path of my signal or a change at the transmitter. Weather conditions do have some affect. High pressure tends to cause me problems, but once they clear I used to get back to normal reception. Now, reception is almost always poor. BBC is impossible to tune. I have installed a satellite dish as an interim solution, but would very much like to resolve my aerial reception issue. My problem is further enhanced by a poor broadband speed and so on demand television is not a practical solution. Looking forward to any assistance,
Kind regards,

Can't find any reported faults either by Freeview or the BBC, and the Mevagissey transmitter isn't currently listed for Planned Engineering.
There has been a lot of "Tropospheric Ducting" accompanying High Pressure over recent months, most recently it did affect quite a few areas of Devon and Cornwall as well as other parts of the UK from time to time. However it is currently totally clear according to current predictions.
Without a full postcode, we can't look at what your predicted reception might be, or what even the typical Line-of-Sight to the transmitter might be. That in any case would not take account of any new buildings or trees etc on the L-O-S.
Do you have any trees near you that have grown larger and maybe on the LOS?
Whilst you've had your aerial checked, have you changed you installation in any way?
Also check any wall-plates, 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 the multiplexes (groups of channels) shown in your TV's tuning section.
The UHF channels for Mevagisey are C46, C43, C40 in the order BBCA/PSB1, D3&4/PSB2, BBCB HD/PSB3.
Are the BBC ones poorer than D3&4?
Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.

Hello,
Can you let me know if we will be able to watch Channel 51 (great Christmas movies) from the Caradon Mast in the future.

W raynham: Try asking the broadcaster. Sony (who used to own the Great channels before selling them a while back) reduced the coverage of several of their channels a couple of years ago, resulting in some of their channels not being available to large parts of the country. The new owners may decide to change this when spare capacity becomes available, however nothing has been announced.

Just to add to what has been said, as you may know LCN51 is carried on Local multiplexes and there isn't one at Caradon Hill, they are only broadcast from a limited number of main transmitters serving large urban populations, the signal is lower power and in most cases beamed towards those specific urban areas.
See Channel listings for Industry Professionals | Freeview for which channels are carried on which multiplexes.
Also the channel listings towards the top of this page haven't been updated since the 700MHz Clearance programme, both COMs 7&8 closed at Caradon Hill on 19th June 2019.

Hi
I have lost channel 26 and 81 is there a fault on your transmitter this has been happening over the last couple of days

Michael townsend:
It's not "our" transmitter, this is an independent free helpsite. Arqiva own and maintain most UK transmitter sites.
I assume you mean those channels in your EPG (as 81 isn't a UHF channel) - both of those are carried on the ArqB/COM6 multiplex. You will no doubt have lost others on ArqB at the same time. Do NOT retune.
You may have them back by now.
See Channel listings for Industry Professionals | Freeview
for which LCNs (channels in your EPG) are carried on which multiplex.
I can't find any faults listed or Planned Engineering for Caradon Hill. It's quite possible that you lost them due to an isolated fault elsewhere, or more likely - if you've also lost other ArqB channels it could be weather related.
There is currently some predicted "Temperature Inversion/Tropospheric ducting" for parts of the SouthWest. This causes signals from distant transmitters in the UK and Europe to travel further and cause interference to some UHF channels. It doesn't affect them all at any one time, it can last for seconds, minutes, hours or sometimes even longer. As already advised, do NOT retune, you will likely lose your correct tuning, maybe end up incorrectly tuned to other transmitters' signals which will eventually disappear.
IF you've already retuned, check in your TV tuning section that you are correctly tuned to the UHF channels for Caradon Hill.
In the order PSBs1/BBCA, PSB2/D3&4, PSB3/BBCB HD, COM4/SDN, COM5/ArqA, COM6/ArqB, -
the UHF channels for Caradon Hill are C28, C25, C22, C21, C24, C27.

Bad signal on all channels - i.e channel 1 and channel 101 digital. Three televisions on property - all experiencing problems - is this because of the high winds??

Mr&Mrs Williams:
If it is due to "high winds" it's highly unlikely to be a transmitter issue, but more likely a problem with your own aerial. But as we don't know which transmitter you get your signal from, we don't know if there's a transmitter fault.
We'd need a full postcode and ideally the direction your aerial is pointing to check on that.
I would check that your aerial seems intact and pointing in the correct direction and that your downlead looks undamaged (especially if it is old) and is secure and not flapping in the wind.
Have you checked the connections behind your TV?
I'd 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.
Problematic connections, water ingress, Aerial misalignment etc., can seem to affect reception of just an individual or several multiplexes.
