Brian I appreciate that may be the case but we are still experiencing random drop out of 'coms', mainly itv3,5,31,30. A complete clean tune seems to bring them back, it is not restricted to one aerial but happens on all 4.
A pain to retune 11 televisions.

Robert: The COMs from Oxford are on low power until 18th April.
Once it has been established that they are tuned correctly, then don't retune as nothing positive can come from it.

I have just acquired a Polaroid TLU-01941CU LCD TV for the above postcode. It was working fine in Sussex (pre digital changeover) on all channels.
I have unplugged the aerial connection from another TV (working perfectly on all channels) and connected it to the Polaroid TV. No matter how many times I perform full autoscans, factory resets, etc., it stubbornly refuses to tune any ITV channel, Channel 4, Channel 5, etc. (in fact any channels on Muxes 2 and A I believe).
I have repeated the process using a second aerial (that operates all channels on another TV perfectly) with the same disappointing results.
As the two separate aerials work perfectly well with the two other TVs (and two PVRs), I suspect that the Polaroid TV tuner is at fault but would appreciate your comments before I consign it to the skip.

Paul: Try manually tuning to channel 60 for ITV1, ITV2, C4, C5 etc (if there is a manual tuning option).
At 10 miles from a high power transmitter, it could be that the signal level is on the high side and it is that which is causing it not to pick up these channels.

You show that the ITV1 Oxford HD freeview broadcasts the Meridian programming from Southampton. This is not the case. It broadcasts ITV Central from, Birmingham. Adverts often come from Midlands traders with no connection to the Oxford area and the local news at around 10.30 pm is the Midlands area news. Mind you, the Meridian news on ITV standard chanel is mostly south coast news and of little more interest to Oxford area viewers than the HD Midland news.

Are there any plans to boost signal from ArqA? My reception of E4+1 and Sky News is dreadful. Everything else comes in fine.

My aerial points toward the Oxford transmitter from OX10, and I was happily retuning as requested when we switched over last September. However, a couple of weeks ago I was prompted to retune again by a pop-up on the screen. I can't remember exact dates but this seemed to coincide with the Hannington switchover.
I now get two versions of lots of channels, eg: BBC1 South & BBC1 Oxford. But they are fairly intermittent. Should I remove the masthead amp on the loft mounted aerial?

Stan Herbert: I wouldn't just yet anyway, but what you should do is scrub everything already stored by taking the aerial out and carrying out a re-tune without it, then after this has been done keep the aerial plug in your hand and select to carry out another re-tune observing the progress bar as soon as it starts, then as soon as you see Ch47 being passed "immediately" reinsert the aerial plug again and that will store only Oxfords channels.
If though your TV's tuner doesn't have this type of facility, then after scrubbing everything stored you will need to manually tune in each of Oxfords muxes one at a time, the channels involved being: 53 - 60 - 57(HD) - 62 - 59 - 55.
If after having completed the scan you find that BBC and ITV has developed glitches in various ways then remove the amplifier, as it will likely be a signal overloading that is causing the problem.

jb38: Thank you for your help - I've just unsuccessfully tried this, but that is due to the limitations of Windows Media Center which receives our TV signal. It doesn't give frequencies and doesn't allow manual tuning. Weirdly it doesn't even seem to work through the frequencies in a logical order as it finds two BBC1's within the first 1% of searching, when the two transmitters seem to broadcast these channels on very different frequencies. Maybe I'll try without the amp and see what we get then!
