In response to AD.....I too have had signal issues since Saturday on the Mux 2 (ITV etc) from the Crystal Palace transmitter. I have a varying signal strength. Hopefully as previously mentioned here, it is the inversion effect, althouth I feel this is a pretty poor excuse! Can't wait for 18th April when we finally switch in the London region and the digital signal is boosted.
All of the transmitter engineering listed on this site mentions BBC and not ITV so it must be the atmospherics.

Hello - this is an update to my query raised Sunday 8 January 2012 8:09PM.
I finally found the time to check all cables & connections and found a loose connection from the signal booster. Once this was sorted then the digital pictures were visible once more.
My thanks to those that replied!

Tim.Yes it is atmospherics/inversion effect that is causing yer difficulties,and yes once Crystal Palace goes fully digital on Wednesday 18 April 2012 yer problems will hopefully disappear,more so after Wednesday 27 June 2012 (Wed 13 June 2012 Heathfield mast) when Bluebell Hill,Dover masts go fully digital as well as Sudbury's restrictions on the COM mux's are lifted (going fully powered).

I apologise for the slightly extra postings on the above due to a sudden connection failure on the internet a few moments earlier.Apologies all round.

To the many viewers receiving horizontally polarised transmissions from the Crystal Palace mast who suffer from inversion/atmospherics,i may have finally uncovered what causes the lower powered pre-digital signals on multiplex 2 (Mux 2) on frequency 22 especially to pixellate,break up and disappear into "No signal mode".It is possibly due to the higher powered post-digitally switched 150kw BBCA multiplex signal from the Belmont transmitter also on frequency 22 to swamp the lower powered Mux 2 signals (fr 22) on Crystal Palace mast.That is my possible conclusion.

Tim.I'm pleased that your reception has improved since Tuesday (17 Jan 2012),as low pressure swept in later that same day,which forced out the recent high pressure over your location causing all the problem with atmospherics/inversion.
