Reception on all BBC channels very poor from Llandonna on 22 August 2016.
Tried retuning Freeview several times but only getting Quality 1 on BBC 1, 2, 4, Red Button and Radio. In fact of all BBC associated channels none are registering above 1.
Why?
All other channels are showing Quality 10, even the Channel 4 stuff which usually suffers more than anything.

Brian Springthorpe: If all the other muxes are fine (and don't look at just quality, you need to be looking at signal strength, which should be around 75%), that points to a problem with your aerial system. Just because a wire might be frayed or damaged, doesn't always mean that the strongest signal will be the one that gets through - wires do weird things. For a start, change the aerial lead - cheap, easy and if it was duff, an easy fix. If the problem remains, then you need to look further up the signal path.
But if your getting a very high signal strength (which is why a postcode is so useful), then the BBC channels might be the ones to go crazy - they are likely to be the strongest. So check out the page called 'too much of a good thing'.

Brian Springthorpe: Reception in many parts of the UK is presently being affected by a series of high pressure zones sweeping across the country, the effects of said pressure being most likely reason for the reception problems referred to, unfortunately nothing can be done to help rectify the problem except to wait until the situation improves.
