We keep getting 'no signal message' around 5.00pm everyday.
Is anybody else getting this.

Linda Greenway: If it's happening at the same time every day, the most likely explanation is that you're suffering from electrical interference being generated by something operating on a timer (probably something with an electric motor such as a central heating pump).

Any reason for poor reception on C24 ITV Channel 4 Channel 5? Picture breaking up. Good reception for BBC 1 and BBC 2. Post code PE13 5LB. Roof top aerial.

J Knights:
Look at the digitaluk trade box below your post (or look at Coverage Checker - Detailed View which is the same) and you will c=see that some multiplexes are rated as variable, so weather, etc could well affect them. Please check all your aerial cables and connections to ensure they are making good contact throughout.
Note that the 6 June retune will require a change to a wideband aerial unless you already have a good one fitted.

Dear UK TV
I have had no TV Transmitter signal since 28th May 2018 (over 48 hours)! Has Transmitter retuning been brought forward? If so, how long before normal service is resumed?
Ps I have already tried retuning my TV set, and internal diagnostics suggest that the TV Transmitter is switched off!
Yours sincerely J Foley.

Jerry Foley : The first frequency changes at Sandy Heath don't take place until 17th July (according to Digital UK) and there is no engineering work reported. Have you checked for any loose or damaged cables or connections behind your TV? Retuning was a bad idea as you've now deleted all of your channels which were correctly tuned.
