Transmitter engineering: Could you advise if there is an ongoing issue with the Caradon Hill transmitter in Cornwall. Over the last week or so, some channels are quite pixelated, but the most noticeable problem is sound distortion. Channel 35 (ITV+1) is one channel in particular. Sound is muffled and distorted all the time, no drop-outs, just distorted. I am aware there is or has been some engineering works recently and just checking if my problem is likely due to this, or if I need to investigate other causes. Any help or advice would be appreciated. Many thanks...

The post before yours (now at the bottom of p50) states that there is still Planned Engineering work continuing.
A lot of main transmitters (and some others) have been having extended maintenance during the last 12 months or so. It's over 10 years since DSO and it's highly probable that extended maintenance is likely, it's not only transmitters and antennae but the structure as well, eg. to ensure that is remains safe and not likely to come down in severe weather. You may have noticed that there've been some severe storms of late!
We know that on some transmitters the work has involved such things as the greasing of stay cables and so on to inhibit corrosion etc. So it's highly probable this is the sort of work that's taking place.. It'll take considerable time and reduced power or interruptions will be needed when working close to the antennae, hence it states there could be "Pixelation or flickering on some or all channels"
If you give a full postcode we can check your predicted reception which may indicate how vulnerable you might be to these problems.
