Jeff: Well Mux Ch31 is shown as zero reception at your location until 9th of May 2012 when it changes to Mux Ch51, however Mux Ch67 should come into the equation from 14th of this month when it changes to Mux Ch48, likewise with Mux Ch40 on 23rd of November when it changes to Mux Ch52.

I figured out the problem,all I had to do was switch aerials.
The aerial I was using when it stopped working was a mini one, find it hard to believe that it just stopped received mux 22 channels.
What do you think happened?

James: Its most likely that the signal level just dropped under the receiving threshold of your set, as its likely that it wasn't running at a level that very much above it in the first place, that's why I asked if you could carry out a signal check so that this could be assessed.

Well it seems that you were right. Hopefully the signal level will pick up soon, this large aerial is hideous.

Hi,
I get a good signal from an old set top aerial when I point it to Sandy Heath. I'll keep my main roof aerial pointing to Crystal Palace though.
Thanks for all the info. I know this is all part of them sorting things out foe the eventual analogue switch off. Time will heal, I hope ;-)

PS C21+ was picked up ok by my PVR but I had to tweak the other box to look for the 474.2MHz channels rather than 474 MHz as it ignored them on first scan.

I'm missing all the freeview channels in groups 2 and A above, i.e. the ones showing as low reception from Crystal Palace. I've tried two different aerials. Is there anything I can do about this? I'm in SE13. (51.4646,-0.0203)

Laura : Try a third aerial, it worked for me. I had your same problem.
I want to use my original aerial, so I'm just waiting for groups 2 and a to go back to maximum power.
