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.

Are there any planned engineering works or unexpected transmitter faults on the Oxford (Oxfordshire, England) mast?

... in addition C62 is going to be reallocated for use by 4G mobile services.

Briantist: Yes, but that's not yet in the Digital UK postcode checker. If the conclusion is that the interference from those relays doesn't significantly affect that many Oxford viewers, chances are that Oxford and those relays will be moved to the same channels.

Ofcom's latest 'Table of Digital Stations' (version 5) now has High Wycombe and Assendon BBC B, and Chisbury BBC A, using C50 rather than C62 from their DSO dates. So perhaps that isn't the source of interference, or not the whole story.

The next nearest transmitter using the same channels is Midhurst, and of course this is a relatively high-power main transmitter using horizontal polarization. The variable reception prediction may just reflect lift conditions. At present C55 is an analogue channel at Midhurst, C59 and C62 are low-power digital multiplexes.

Mike Dimmick: I can't help noticing that funding for "Digital UK" will dry up once the last switchover event has taken place, so I can't help wondering if "Digital UK" will have anything to do with post-2012 changes to the broadcasting arrangements, beyond what is arranged for pre-DSO stations.

I will have to go though http://licensing.ofcom.or….pdf and look for all the relevant changes.

I suppose there is a possibility that the post-2012 changes shown here are caused by changes from international stations, as they are for the Brighton area.

Thanks for the reply on "variable reception" from Oxford next year. I live near Northleach in Gloucestershire at 752 feet above sea level.

All along their "post code checker" has been somewhat dodgy and taking into account your comments I suspect my reception will not change much, if at all.

I note that the digital change over in the USA took place on one night, that is, all stations coast to coast in one night, pity our lot couldn't manage that!

Keep up the good work.

Algernon Black: In the US there were sufficient frequencies for the full power replacement digital services to be in operation for many years.

This is because the US terrestrial system is city based and does not cover what we would term "rural areas".

So, the US was a "switch off analogue" event, not a "switchover event" as here, where the low power digital and high power analogue services are replaced with high power digital.

With almost 100% coverage in the UK, this means a rolling switchOVER plan.

It is highly unfair to compare different implementations.

Why are some of the multiplexes transmitting on low power?is it to save electricity?

Andrew.The SDN,ArqA & ArqB mux's from the main Oxford transmitter are transmitting on lower power not to save electricity,it is more a case of avoiding clashes with nearby regional transmitters/relays that are either now all digital,or still broadcasting analogue and low powered pre-digital switched signals using the same frequencies as that of the Oxford mast,more so the current understrength SDN ch62,ArqA ch59 & ArqB ch 55 mux's which had they're been on full power by now will affect nearby transmitters/relays broadcasting on ch 55,ch59,ch62 whether already digitally switched or still broadcasting analogue/lower powered pre-digital switched signals.Im sure the true pros on here,Briantist,Mike Dimmick,JB 38,etc,will give more professional assistance as such.

Can anyone help, please? We have a Goodmans Freeview box and also an old Wharfedale Freeview box. Everything was working fine before the Digital Switchover, but now our pictures (on most channels) frequently freeze and then jump. Also, we often get a brief, strange sound (a bit like a switch), followed by a brief reduction in volume before it gradually improves. Confusingly, it doesn't seem to happen much when the telly is first switched on, but gets worse.

Better on the Goodmans box, but it still happens.

Any advice gratefully received - thank you!

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
