The symbol shows the location of the Oxford (Oxfordshire, England) transmitter which serves 410,000 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.

Yes, as I said, I turned off everything that could possibly be interfering and it made no difference. I've looked at the wideband aerial page but it seems unlikely to me that the "primary" channels would be the ones not showing up in that case, though I may be wrong.

Okay, going through that in order - 1. The signal hasn't changed; I haven't been able to get it to work at all since we hooked up the TV a month ago. 2. All other channels are fine, perfect picture and reception. 3. Analogue signal is fine. 4. No variation as far as I can tell, channels just don't work whenever I go to them, it's not a sometimes-working sometimes-not scenario. 5. Cables are all brand new. 6. I cannot check the aerial as it is on top of our block of flats; if the problem turns out to be absolutely definitely the aerial I can ask our landlords to do something about it, but I'm reluctant to do so unless I'm really sure that's the problem 7. I would expect that weather related problems would also affect other channels?

Helen: Apart from trying out what Briantist has suggested on the link he provided, however if you find than none of what's mentioned seems to apply, then you have to consider that there is always the possibility that the signal you are receiving on that particular Mux channel is on the verges of being too strong, as you are only 4 miles away from a 10Kw transmitter using a roof mounted aerial.
It has to be appreciated that no two sets respond exactly the same to an over strong signal, and the symptoms you mention "are" in line with what can happen with this type of problem, as that's the thing about digital reception, too strong a signal can give exactly the same symptoms as one that is too weak.
The only way of verifying the cause of the problem is by either trying out another device,(TV or Box) or placing a simple attenuator in line with the aerial socket, these obtainable from most TV shops, but if you have anything like an old VCR or similar try placing that in line with the TV's input by using its (the VCR's) aerial in / RF out sockets, as that will in most cases reduce the signal strength enough for a test, if it doesn't switch its power supply off "whilst still watching the picture", as you might then see it suddenly get better before vanishing, this indicating the signal is too strong.

Helen: Meant also to say, that another good test would be if you could try your box / TV using a set top aerial, should you be able to borrow one that is! (testing only on the Mux 1 problem)Helen

Helen suggest you obtain a variable attenuator & play around to see if it makes any difference. Maplin do one for £7.99 (Catalogue code A03HT) and it is in stock at their Botley Road store. If you are receiving too strong a signal then this is definitely gonna get worse after DSO.This one varies from 0-20db attenuation so you should be able to play around withg it

MUX 1 from Oxford is on UHF channel (frequency) 34. That frequency is often used by video machines and satellite receivers to send an analogue TV siganal to the TV. If there is one of these devices between the aerial and the Freeview box, it would block reception of MUX 1.

I think UHF Channel 36 is most often used by SKY & Video boxes. Will this channel be used in the future for TV or mobile phone use? Thus messing up any home use of this channel to pipe Sky to other rooms at home.

Bill: C36 is a DDR channel. It was previously used for RADAR and should not have been used on any TV equipment.
