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.

David Roseveare: The Caradon Hill transmitter has been listed for engineering work for the last few weeks. Unfortunately no information is given regarding what work is taking place or when it is due to be completed.

Is there any information anywhere on the kind of engineering works notified as being undertaken on so many transmitters?
The only clue I have is of antenna units being replaced locally by European-sourced units.
If this were happening on a wider scale, a reliability issue might explain it.
Checkiing local planning applications might be worth a try...

michael :
As you know from previous posts, Arqiva don't provide the details. Whilst replacing antenna units is one possibility, where did you glean this information, and are you talking about Caradon Hill itself?
Even if it's definitely the case, why do you think it might be a reliability issue? Surely the age of most of the units could have a greater bearing on this?
Perhaps European- sourced units are the only currently available source?
Somehow I doubt it's a widespread thing as I would expect it to cause more disruption than appears to be the case going by posts on this site (and come to that elsewhere).
One thing we do know is the odd bit of information that appears such as -
Engineering work affecting BBC radio services from the Rowridge transmitter from 1 May until 10 June 24 | Help receiving TV and radio
and I recall a similar one for Wenvoe a while back, but it didn't only affect FM at Wenvoe.
It strikes me that this type of work is a much more likely need at many transmitter sites considering the age of many masts, never mind mentioning the more severe weather we get these days!
I wouldn't have expected any of the above mentioned maintenance work to have require planning permission in any event, there's no material change to the structure or the site.
