Thanks Mark. Fourth retune has now brought back remaining channels. 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 Crystal Palace main transmitter: TV (analogue) Liable to interruption". So perhaps that is a more likely culprit after all?

Airial is on the roof.It is a sheltered housing scheme for older people & lots of the tenants have no or little TV reception over the past week. I am the manager & trying to get some answers for my tenants.
We know that our airial is ok its been checked before so why is there a problem can you please tell us?
thank you

Freeview signal very poor as of wed 14th/thur 15th march. I live in east grinstead and look at the Crystal Palace for my signal. Previous spasmodic problems, looking to the changeover to solve everything. Now unwatchable on digital but analogue is ok.

John Langridge: Weather conditions since Wednesday have resulted in out of area signals traveling further than normal due to the inversion effect. Many viewers experienced interference to TV reception as a result. Mux2 is currently predicted to give variable reception at your location, on 18th April 2012 the frequency will change to that currently used by analogue BBC1 and the power increased to 200kW. You are then expected to have excellent reception these channels.

I am in Bermondsey, clear Line Of Sight with the Crystal Palace tower. I have a "Technika" STB which has been happily upgrading itself and now, since Friday Night/Suturday Morning (16/17 March 2012) when it did its last "Guide update", it tells me no new channels have been added. That is all I get... no guide, or list of channels.
I tried auto channel updates and it does run through the channels, some take longer than others, but the end result again is, "No channels have been added, check your antena"
When I do a manual channel update, it only gives me the option to enter channel numbers between 22 and 69. When I do this it tells me the signal strength and quality of some channels are good, but when I try to add the channel it tells me that the channel is not found.
I was hoping to find many similar comments on this board - maybe a failed firmware/os/crypto update? - but it seems this problem is vey much localised to me! :-) Yet, if anyone can give me advice/guidance, I would appreciate it. Or maybe it is just the annual replacement of the technika.
Thanks for your time.

Pete, I too had a Technika and ended up getting my money back as I was unhappy with the picture quality. I now have 2 Logik (Curry's/Dixon's own brand) LED TVs in the bedrooms and they have given excellent results

Pete: Anyone experiencing odd problems such as you have described is always advised to carry out a complete default reset on the box to return it to its original state, then this action being followed by a fresh auto-tune.
The reason for this being necessary is because that in common with all digital equipment glitches can always occur when updates etc are taking place that results in the data being corrupted, and with complete elimination of whats already stored being the only way of getting around the problem.
