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?

Mike,

Thanks for your help. It was mux B from Crystal Palace on ch 28 that was causing all the problems with the Oxford EPG. Did a retune pulling out the aerial after ch 27, and putting it back in again very quickly at ch 29! All the Oxford channels are also now back in their proper place, with Crystal Palace in the 800s and Sandy Heath in the 900s.

HD channels. I suspect that my freeview receiver (Philips DTR 220/05) isn't technically capable of resolving the BBCB HD mux. I have tried a manual tune for Ch.57 but it found nothing. All other mux's are showing 100% now.

Can someone kindly confirm my findings...

Spartan:

Your suspicions are correct, the box cannot see HD transmissions.

Hope this helps,
Adam.

Spartan: Yes, you are quite correct, as that box is not fitted with a DVB-T2 tuner which is necessary for HD reception, the DVB-T tuner as is fitted in your box just ignoring HD signals.

For several days the reception in our part of Headington for ITV3 has been lost- I retuned a digital tv today and am down to 80 channels from over 100 after the switchover in September. Is there anything else I should be considering ?( I have my Father on at me from time to time).

I note from the web page of Digital UK (www.digitaluk.co.uk) that from 2012 the transmissions from Oxford will deteriorate.

I have taken up this matter with Digital UK and they replied:-

""Our postcode checker does suggest that you may receive a good overall reception on around 18 channels and a variable reception on around 48 channels in 2012.""

Surely this is totally unacceptable.

Algernon Black: Because the switchover programme is still in progress, a later change at another transmitter can affect some viewers. If they'd switched everything over in one go, this wouldn't have happened - and you'd never have noticed.

Most likely you're in the south or south-east of the coverage area, near High Wycombe, Assendon or Chisbury. Those three transmitters' PSB multiplexes will clash with Oxford's COM multiplexes. The commercial multiplexes are not required to meet any specific level of coverage and certainly not to match the PSB multiplexes, which are required to substantially match analogue coverage.

'Variable' reception in Digital UK's postcode checker does not necessarily mean variable results. It means that using their aerial model, the percentage of locations that should, on average, have reliable performance 99% of the time, is below 70%. It means siting an aerial to get reliable results will be more difficult than if the 'good' standard was met. The aerial model is quite pessimistic, compared to real aerials, regarding rejection of signals from other directions and from the other polarization (those relays will transmit vertically-polarized signals and Oxford uses horizontal polarization).

High Wycombe and Chisbury already use C55/C59/C62 for their analogue transmissions, but a digital service does do more damage to another digital service than an analogue one does. Assendon uses C55 now and will start using C59 and C62 at switchover.

If you do find you are affected, you may be able to fix the problem by rotating the aerial slightly towards or away from the interfering transmitter - real aerials have peaks and troughs in their 'polar response' - how much signal is picked up from different directions - and you may be able to drop the interfering signals into a trough in the response.
