Hi, our house number is 11. The aerial is in the loft. We can receive the Darvel Local MUX channels with excellent reception (8 That's TV Scotland, 50 Great TV, 52 Great Movies Classic & 61 Great Movies +1, but not the Darvel Main transmitter channels! Previously, we could receive the Darvel Main transmitter channels until 1 week ago, but they would often freeze or have a broken up picture, they had been like that for about 3 months or more and have got progressively worse until they have gone. We thought it was down to the weather conditions, but now we have totally lost the Darvel Main transmitter channels and cannot manually retune them. We have tried the Freeview reset procedure. The good news is we used to have a huge woods which may have blocked the signal, but it has just been chopped down, but this has made no difference to reception.

Hi Chris, thank you for your response, sorry I posted 3 times, but it came up as an error each time I posted, but I did not realise that it had gone through. Postcode is KA7 4EE, we are on a north to NNE facing slope about half way up. Several years ago, we had our aerial professionally installed. The installer wanted us to have a roof mounted aerial, but we suffer a lot with blustery weather and it would have lasted about 5 minutes, so he installed a 2 metre long aerial in the loft. He said at the time the trees in the woods might affect the signal, but it has been OK, until a few months ago. 3 weeks ago all the trees were cut down and I would have expected the signal to improve, but it hasn't.
Yes, it is definitely UHF C31, as I manually tuned our TV to 31 and that's why I listed the channels we receive with a strong signal so you could confirm I had actually tuned to UHF C31. On our LG TV when you manually tune it shows the signal strength and signal quality. I have tried to manually tune it to Darvel on the other UHF Channels 22, 25, 28, 32, 34 35 & 55, with no success. Tonight suddenly UHF C25 came back but with low signal quality fluctuating between 17-33%, signal strength is 100% and I have just managed to manually tune UHF C28, again with low signal quality of 17-33%, but high signal strength 100%. UHF C55 shows 0% strength and 0% signal quality, C22, C32, C35, show 100% signal strength momentarily with 0% signal quality but as soon as I press the update button, the signal strength drops to 0% after a couple of seconds. For the TV channels on UHF C25 & C28 they freeze or have a broken up picture, I guess this is due to the low signal quality of 17-33%. Could I ask if the Darvel Mux different to the main Darvel transmitter in terms of vertical or horizontal modulation? Could that be why we are receiving a strong Darvel Mux signal, but a poor Main Darvel transmitter? Thanks

Hi Chris, thank you for the detailed response. We don't have amp/splitter with gain control. I will try the points you have suggested over the weekend and let you know.
