Like Norman in Stevenage, I have also lost most from the this evening (first pixellated, then completely lost). After retuning my STB, I seemed to have channels on MUX B, C and D, but nothing on 1, 2 or A. My Freeview has never been great, but I've never had any problems with BBC1 & 2 before. Having just retuned for a third time, I now seem to have MUX 1 , but still nothing on MUX 2 or A. Can this really be an atmospheric thing, or is it some precursor to next month's changeover? Hopefully the former, rather than another month of such flaky-ness!

Thanks Mark. Fourth retune has now brought back remaining . Might have expected atmospheric issues to be a bit longer lasting (or, at least, not to 'clear up' one MUX at a time)? Have also just spotted entry above "Over the next week main : TV () Liable to interruption". So perhaps that is a more likely culprit after all?
