Steve: The reception predictions seen for your post code does not for the time being indicate very promising, insomuch that your present reception of Sudbury's PSB muxes plus SDN (ITV3 etc) is about the only choice you have, even at that the SDN mux is indicated as being variable, meaning that glitches in reception can be expected.
I don't feel that you would really achieve anything by changing your aerial as the missing muxes (ArqA & ArqB) are not indicated as being possible to receive anyway, and so called high gain aerials have a lot of hype attached to what they can actually achieve, as the only time that they "might" give a positive improvement is in circumstances where exceptional distances of a near line-of-site nature are involved, your situation at 19 miles not being!
However, from June 27th you should be able to receive all six muxes from Sudbury when the presently low powered commercial muxes also start transmitting on high power, as the PSB muxes are presently doing.
By the way, you are not predicted to have good reception from Crystal Palace at any time and that's right into 2014.

jb38. Thanks for your help, much appreciated.
I just noticed that the "enhanced Freeview reception prediction" for my post code CM9 4SF shows Blue Bell Hill as the 1st choice (Dover is 2nd choice). It's a line-of-sight transmitter but 29 miles away, isn't that a bit too far on it's current low power? No point in waiting for BBH to go to full power as Sudbury changes at similar time.

steve bevan: Well although predictors (any!) do have their faults because they cannot really cater properly for reception problems that may be in existence caused by for instance the local terrain, the Digital UK's trade view predictor (link below) which I use as a guide shows Bluebell Hill in effect as being no-go for your area, as everything seen is a mixture of poor or variable, or in some cases nothing at all.
Dover on the other hand is of course shown as presently being possible, but as far as reliability is concerned this only really applies to the PSB muxes, as although from 27th June two of the three commercial muxes may well come on board but with the permanent status of variable, and not even good at that! and nothing at all shown for the ArqB multiplex.
There would be nothing stopping you from experimenting as in nearly every iffy reception area little pockets of good reception exist, but rather than changing the aerial which as aforementioned wouldn't in my opinion really achieve anything, using an amplifier of about 15dB or so inline with it, the dB figure mentioned being ideal for experiments.

Does anyone know if the +/- 167 offsets will still be used on Crystal Palace after Digital Switchover?

Postcode GU15 1ER, aerial pointed at Crystal Palace, with high gain roof aerial and booster amp, feeding 2 Sony TVs. Previously received 104 channels on Freeview. Now receive 42 channels on Muxes 1, B and C only with signal good and additionally Mux 2 on the other TV with high signal. To me this looks like a signal level issue from Xtal Palace. I've obviously done all the checks suggested. Any other thoughts?

lisa: Its really a case of them moving channels rather than completely disappearing, as from April 18th the only channels that they will apply to is Mux Ch30- (HD service) and ArqB (Yesterday / Film4 etc) Mux Ch28-.

hi I am on the edge of your range at RG5 4LY and have 63% signel and 90% quality on my freeveiw+ box. had a new aerial fitted this week but still have subtitles missing on recording and occaisonally have slight picture breakdown . could this be due to work on change over and could this error go away after your change over in april?
thankyou G Checkley

g.checkley: The power will be increased at switchover which should solve your problems.

Will the Crystal Palace transmitter still use the 167 offset frequencies after DSO?

Thanks jb38, just seen your answer, I may have accidentally cross posted.
So, is there somewhere online that lists the exact frequencies that CP will be transmitting on (including the offsets if appropriate) post DSO?
