Many thanks for your reply jb38,it was the limited analouge channels from Icomb that made me experiment with a raised aerial etc to try to get Oxford Signal, and 95% of the time I get a very good clear stable picture on all channels, its just the odd 5% when I get picture breakup, so I think I will worry about 2013 as and when. Thanks again

TVs with inbuilt Freeview all retuned after change over. Now they have no signal or crackle on BBC channels. Checked signal on Panasonic TV and 100% then drops to Red and then lost and returns?".
Is this thread about Oxford? DSO hasn't happend there yet. I think you are talking about DSO of Sandy Heath.

j bond: Thanks for the update etc.
Trade (or any) predictors can never really accurately cater for what it is actually receivable in real life, that is when dealing with reception in an area that's considered to be problematic, however what you have done as far as experimenting with the aerial is concerned (raising it etc) can frequently bring results, as indeed obviously applies in your case.
Of course the only thing that has always to be kept in mind is, that the signal received "might" only be possible because of a reflected signal, so continuity of reception is never really guaranteed throughout an entire season.

Currently I'm receiving all Beckley digital signals fine here in east Witney; quality is:
Ch 29 MuxD - Very Good
Ch 34 Mux1 - Very Good
Ch 48 MuxC - Medium
Ch 51 MuxA - Poor/Medium
Ch 52 MuxB - Medium
Ch 68 Mux2 - Medium
My antenna is a Group C/D yagi.

mba12: Looking at the top of the page there are only analogue problem reports, meaning the digital signals are all OK. If you're having problems please see Freeview reception has changed? | ukfree.tv - independent free digital TV advice .

Hello all,from the info given here It seems that the transmitter signals on most of the MUX is going to be around 12kw.So,from this I must assume that we would possibly experience more reception problems in poor weather times wet/cold,as the old power level of the analogue transmissions were 500KW.
I thoght that I had read somewhere that the power levels would be much higher than 12kw after switch over?
Have the goal posts been moved?
The info here also states that" Ofcom have mentioned Projected C49 and 29 could be used at Oxford for local transmissions)But does not say that it WILL do this!
Strange.

Phil dickens: If you look above at "Comparison of analogue and digital signal levels" it clearly shows that the PSB multiplexes will be 100kW and the COMs at 50kW.
But, as a interim measure the COMs will have to wait a little while as, "SDN, ArqA and ArqB restricted to 12.5kW after switchover until further notice"

I'm in OX4 and for some reason I just can't get anything on Mux 1 - i.e. all the core BBC channels. All the others are fine and great quality, it's just this mux that isn't coming through. I've tried rescanning channels several times on both my freeview box (BT Vision) and just by scanning for channels on the TV itself. I've turned off and unplugged all game consoles, the BT Vision box itself, the DVD player - reduced it down to the aerial cable plugged into the TV itself - and the channels are still unwatchable (jumpy picture and sound, blocky). I don't understand why it's the mux with the strongest signal that's not getting through...
