The symbol shows the location of the Hannington (Hampshire, England) transmitter which serves 470,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

trevor: Since 4th April 2012 analogue ITV1 from Crystal Palace is transmitted on C33 instead of BBC2. Digital Mux BBCA is transmitted on C23 instead of analogue ITV1. This means that your analogue TV now has ITV1 on button 2 and nothing on button 3.

You posted at 6:17PM - CITV only broadcasts from 6AM to 6PM.
Have you followed the re-tune instructions here below? :

Wondering if anyone can explain something. I have been looking at the levels for the different groups of channels. We are receiving PBS1 perfectly- my question is why are we not receiving PBS2 at all? According to the information at the top on levels PBS2 should be at 50,000 already - ie the same signal strength as PBS1.
Just to confuse things more we are picking up Coms 5 (not as well as PBS1 but alright) and that is only broadcasting on 10,000.
Why are we picking up channels broadcasting at 10,000 but failing to pick up some of the channels at 50,000. This may all be resolved on the final switch over date but just seems strange. Any explanation?

tim welby: I believe that the above is not entirely correct.
The Digital UK Tradeview predictor says that the positive offset is on PSB3 (i.e. C39+) and not PSB2. Furthermore, COM4 does not have a positive offset either. Briantist, you might like to look at this.
The Ofcom document, apparently updated January 2012, also says that Hannington's channels are not offset except PSB3:
http://stakeholders.ofcom….pdf
Also, COM5 is on its full DSO power of 25kW. COM4 and COM6 remain on low power until 18th April when the Guildford transmitter relinquishes use of these channels.
Tim, before I started, having simply looked at the channels at the top of this page, I was going to suggest that your problem may be that your receiver can't cope with the positive offset employed by PSB2, but I don't believe that this is the case.
I have been reading through your earlier postings that you made since switchover. You seem to have been having alot of issues since switchover.
As Mike Dimmick explained ( Freeview on Hannington TV transmitter | ukfree.tv - independent free digital TV advice ) the difference between pre-switchover signal strength and post-switchover strength in your direction is huge. You may have had an aerial installed that was sensitive enough to pick up the pre-DSO signals, but which is now drawing in too much signal and overloading your tuner.
The reason for the marked difference is due to the fact that pre-DSO signals were considerably weaker in the general direction of Guildford (the "Guildford notch") in which you reside. This was so as to protect those using Guildford transmitter against interference as the two shared channels. So you have gone from having low low low signals to high ones.
Have you tried fitting an attenuator?

Thanks for your thoughts.
Pre first switch over date we didnt get any signal on any digital channel at all- so there has obviously been a huge improvement. However as you rightly point out, while some of our issues since switchover can probably be attributed to issues to do with Hannington, there are probably some problems within our system as well.
We are waiting till the completion of switch over before we worry about changing our system in any way. After this point we will look into an attenuator and other things.
I was looking up the positive offset (my background is pure mathematics not anything technical) is there something I should do to deal with that.
In my post it was really something that I found interesting that channels I got perfectly (the bbc multiplex) and PSB2 claimed to be the same power yet one comes through perfectly and the other not at all. I hadn't considered that the information at the top could be wrong- you may well be right. It was really a matter of interest rather than anything else.

tim welby:
Me too. I am also going to leave things alone until CP DSO is complete. We seem to be on a similar bearing from Hannington, which also seems to be co-linear with Guildford, and our symptoms seem to be similar to yours. I prematurely thought it was all over but last Monday Hannington dropped out completely (all six), and yesterday both Hannington and CP PSBs were pixellating, both with painful audio interference (not good mid-Grand National...)

Great to know that it is not our system (at least not only our system to blame).
We have found that the PBS1 multiplex (basically BBC) is fine at pretty much all the time. Looking at the levels, it is no wonder that some of the others are having problems being as they are at such a lot lower signal strength.
Thanks for posting, am hoping that means it will not cost to get this working right
