Rob,Chesham.Crystal Palace is an all group A transmitter,using any form of a group W wideband aerial (coloured black at the tips) on an all group A mast in a poor reception/marginal reception area such as from your abode to Crystal Palace mast itself is the perfect recipe for bad/poor/no reception as such.
Because group W wideband aerials no matter what myth that it is a high gain aerial is really not a high gain aerial as such,they (group W widebands,tipped black) perform badly on group A frequencies,more so on all group A transmitters/relays,etc,in a poor/marginal signal area.
You are using the wrong type of aerial a group W wideband on all group A Crystal Palace transmitter in a poor/marginal area,so the correct aerial you should be using is a red tipped group A X-Beam XB16A aerial aimed at Crystal Palace,utilising copper-copper satellite grade black coloured co-ax cable,and importantly using brass co-ax aerial plug for longevity,not alloy or worse plastic plugs as they're useless.

D Ferguson,Bracknell.Is it nice sunny hot with clear blue skies and little or no cloud just recently in your locality ?
The most likely cause appears to be atmospherics or the inversion effect,and as such i would look up Inversion Effect underlined somewhere within my text !

Terry Carter.Colchester,CO5 8BL.
Having checked with the BBC Reception Test via your postcode given,there are no problems with any of the possible transmissions in your locality.
I would look up inversion effect as a likely cause !

Terry Carter.Colchester.What i forgot to add are you receiving from Crystal Palace or either from Sudbury or Dover main transmitters ?
What local news bulletins do you normally receive on BBC1/ITV1 channels ?
