david mitchell: UK show COM7 & COM8 as being available from until at least 2020. Retuning was a bad idea as you've now deleted the tuning data for these multiplexes which were previously tuned correctly. If you've had a recent issue with weak then you may well have a fault somewhere in your system, with COM7 & COM8 being the worst affected due to them being broadcast at much lower power. If you provide a full postcode we can see the predicted signal strength at your location, which may help someone offer further advice.
