Norman: If should inform your son to carry out a factory re-set (or default setting) on the box, as the problem could possibly be caused by the memory having more channels stored than its capable of, hence when switched off they vanish.
However there is another possible reason for the problem concerning the transmission mode used by Oxford over that of Hannington, so maybe you could give an update on the exact model of box you are referring to, this enabling a check to be made.

I used to regularly get Crystal Palace (Ch.23?) in OX13. I had a dedicated Group A aerial up for it. It was slightly 'grainy' at times but a good solid picture. I no longer have the London aerial up there now, but my guess would be it might still be possible once Crystal Palace goes to full power in April next year. You'd need to have a good take off in a south easterly direction with no immediate hills in the way...

Spartan: Well if you managed that result on ITV (Ch23) from CP's 1000Kw analogue transmitter at your previous OX13 location (@ 57 mls) then in theory its possible that a reasonable signal could possibly be obtained when Crystal Palace goes up from 20Kw to 200Kw at DSO.
Of course, glitches etc in the signal which are very likely to happen over these distances are never really noticed so much on analogue reception, whereas they certainly will be with digital an its "cliff effect", so this always has to be taken into account.
The other aspect being, that although you achieved that from OX13, Omar may not dependant on his location, this not having been given at any time.

Hi guys,
Thanks for all the info.I live in central oxford OX1, I have 2 outdoor high gain ariels, 48 element. One is facing the oxford transmitter and the other facing hunnington transmitter. I'm using the hunnington transmitter so i can still get ceefax on my analogue tv and using oxford transmitter for the digital tv's.. Digital ceefax/teletext is just not the same as analogue ceefax.
What do you guys think..??

omar - entirely agree about ceefax analogue being better - mainly because you can still see the full picture, whereas afaik that is never possible with the digital one.
But the interweb thingy has largely supplanted ceefax anyway. And isn't it mostly closed down?

Hello,
I was on another page on here discussing problems with the Oxford signal since the switchover, but I can't find that page any more. So the short story is that I live in Buckingham and have a Sharp TU-160H which is a Vestel T810 clone.
Since the switchover I have lost C59- which someone kindly pointed out is probably due to a problem with the type of Vestel I have and the negative offset of C59.
I have now upgraded my software to V5.9 which has helped a bit. Now when I manually tune C59 I get a sporadic reception showing 'poor' to 'medium' but it doesn't last long enough to actually store any stations. It seems the new software for the box has fixed the negative offset but the signal from the transmitter is too weak.
I used to have a signal booster in the circuit but was advised to remove it as the signals were strong enough already and could be blocking other signals if boosted. It's a big hassle to reintroduce the booster in the circuit as part if it is in the attic and I don't have a ladder, but I could do it if the experts on here definitely believe it will solve it.
Just before that is the recommended procedure, it's worth noting that C55 receives a perfectly good signal whilst being at the same output as C59.
I welcome your thoughts,
Many thanks,
Simon

Simon: At only 17 miles away from Oxford its best that you leave the booster out of circuit for the time being.
To be perfectly frank about it, the only way you can verify if the software up date you carried out has been fully successful is to try and borrow another Freeview device purely for purposes of checking the levels being received between Mux Ch's55 & 59, as although these software updates can effect a cure, its unfortunately not necessarily always as effective as a device that was made correctly in the first place, and so if a secondary Freeview device indicates the levels as being reasonably similar then you know where the problem is.
You see its not just a negative offset problem but this applying along with an 8k signal although the box is listed as being 8k compatible, even the updated version of these chassis can give odd problems when on multiplexes that doesn't have an offset signal, these being exaggerated response to even the slightest signal glitches, or showing a blank screen when first switched on, having to notch up one channel then back down again to trigger it into operation, plus the occasional stuttering of recorded programmes.

Simon - Just a reminder that SDN ARQA & ARQB multiplexes are restricted to 12.5KW ERP until April next year at which point they will increase to 50KW ERP following the switchover of the High Wycombe & Hemel Hempstead transmitters. If you live in a less than ideal reception area & there is quite a big dip in Buckingham then you may well experience reception problems until then.
