On screen messages have now started appearing on BBC1 and BBC2 telling us DSO will happen in October.
Not long to go now.

Caldbeck is not causing all Divis problems unless I and others I know are living in a constant weather lift!
Do everyone a favour and just turn off CH 23 Mux A until it works.
I can bet if there was a BBC licence paying channel on this Mux these problems would not exist!
Now becoming a bad joke!

Carl: If you wait for another 6 months I would imagine reception on channel 23 will be fine.
If you can't wait until then, I'd invest in Freesat. As far as I'm aware, all the channels that are on channel 23 are on Freesat i.e. ITV 3, 5USA, 5*, QVC etc.

Peter: I am an installer it is my customers I speak for when I have to explain why they are not getting channels. 23 and 33 are in my opinion a disgrace at the minute. The quality is poor on my insruments but the signal can be booming in so a 16db increase in October does not give me any confidence at all. I have freesat HD on my main room but it does not show the Quest channel etc.
The good news for Freesat users is that they are adding 24 HD live feeds for the Olympics!
Which you will not get off a transmitter that cant even cope with Freeview Mpeg2. Perhaps this is one for Ofcom?
