MikeB: I do think it is single source interference, which occurs regularly at the same time each day, but which is caused by something outside of my house. I will try different cables, to see if that improves matters.
But this is interference which began at the start of February (it did not occur beforehand). I have no idea how one would go about establishing the source of interference external to your own house.

Chris.SE and others.
I haven't posted for a while as I have a) been on holiday and b) more or less given up on the previously reported issue. I have asked several neighbours about their experience but they are all on cable or satellite.
I was hoping the problem might have stopped at the start of March. It hasn't. Yesterday, I decided to count the number of 'no signal' messages displayed on the TV between 16:00 and 18:00 in 10 minute periods:
16:00-16:10 = 0; 16:10-16:20 = 0; 16:20-16:30 = 0; 16:30-1640 = 28; 16:40-16:50 = 25;
1650-17:00 = 37; 17:00-17:10 = 28; 17:10-1720 = 28; 17:20-17:30 = 33; 17:30-17-40 = 0;
17:40-17:50=1; 17:50-18:00 = 0
Completely exasperated. And with no idea who to complain to. I've got to the point where I have accepted I will no longer be able to watch 'final score' on Saturday afternoons, or watch the six nations rugby and other sporting events at the weekend, or snooker during the week. I've just tried to watch the women's boat race - impossible!

Help! I am in the RG31 post code area and receive signal from Hannington transmitter. Since the beginning of February I have been having problems with low signal quality. I have been monitoring this on my TV diagnostics facility now for 10 days. I noticed that the problem started at around 16:30 each day, including Saturday and Sunday. Before 16:30 signal quality is reliably at 100%. After 16:30, signal quality plummets to below 10% and regularly below 7%. This situation lasts for 70-75 minutes, when the signal quality becomes 100% again. Note that the signal strength does not drop, at least until the low signal quality causes 'no signal'
It appears that something is switched on at 16:30 and interferes with the Hannington signal. 75 minutes later it is switched off and the interference disappears.
What can I do to identify exactly what is going? I do not believe it is 'induction' interference from other appliances, as I am quite familiar with that.
