I had an old TV set with a Freeview box, but replaced it with a new TV which had a built-in Freeview tuner. The box had behaved perfectly attached to my old set. My son recently returned from a work stint in Singapore and brought his large, flat-screen TV with him. It (naturally) didn't have a freeview tuner, so I gave him my old box. It now tunes in perfectly to Freeview, but every time the box is switched off it has to be rescanned. Is this problem (a) the box, (b) the TV set, or (c) some strange quirk of the Oxford transmitter from which he receives signals which was not apparent with the Hannington transmitter from which I receive signals?

Briantist: A few sites slipped through the net, notably for BBC: Kirk o'Shotts, Ashkirk, Peterborough and Les Platons (plus a number of low power relays). For ITV there were transmitters at St. Hilary, Membury and Mendlesham. All the above sites are now in use for DAB and with the exception of Kirk o'Shotts, FM radio.

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?

The loss of in-picture sports scores is annoying - and for fans of Question Time, that of comments as footnotes.

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
