I live in KT7 & use (so far as I know) the Crystal Palacetransmitter. TV is Panasonic with inbuilt Freeview box. Roofaerial about 18 months old. TV has a signal strength & condition indicator. On all channels the strength is always fine, but intermittently on some channels (normally including ITV 1 & Channel 4) the condition indicator goes into the red or fluctuates between red & low orange.
When that happens there is intermittent break up of picture & sound. I also have a Humax PVR & the break up on the recordings is far worse than on the TV picture.
I have checked all the things you mention for intermittent reception problems & none apply (making sure all motors etc. are switched off does not alter the condition). This evening (7 Feb.) the problem was severe from 7.30 or before up to about 9.30, when suddenly - without anything being done at my end - the condition indicator improved to high orange/green.
I find this infuriating. I can't see that it can be anything to do with other equipment in the house. Have you any ideas as to what might help please?
