G LL Williams:
From The Wrekin pages today
"This is very likely caused by the high atmospheric pressure affecting various parts of the country, causing lift conditions which allow signals from distant transmitters which cannot normally be received to interfere with the signals from the transmitter you normally use. Do not attempt to retune as this will delete all of your channels which are already correctly tuned. As this is an entirely natural phenomenon, all you can do is wait for the atmospheric conditions to return to normal."

Look at the Digital UK Coverage Checker results for your location at Coverage Checker - Detailed View That shows you should get good reception from the BlaenPlwyf transmitter.
If you are not then check all your aerial system, checking to any damage to the cables and for any poor connections. If there are coaxial plugs/sockets then unplug thos and refit them, that removes any corrosion/oxidation on the contacts which is a common cause if signal problems.

Philip Davies: Only Sony (the owner of the channel) can do that. No one on this independent technical help website has any influence other the decisions taken by the owner of any channel.
