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?

As far as Channel 62 is concerned no idea what is on it but I am still having trouble with channel 30 mainly which is one the the '5' channels. Rather than the no signal message I get the no aerial symbol appear, which os course can't be right and all the other channels are there.

Generally now most channels appear stable.

I'm in the primary receiving area for the Oxford transmitter so I'm not sure what is going on, but having done a factory reset on my box and re-scan I've found all of the channels that should be on channel 62 but on channel 41.

We're not close enough to any other transmitter to pick up a viewable signal so not sure I'm not sure why it's working on a different channel, especially as others are still wokring on 62, but we've got QVC back, oh joy :)

Stephen: Channel 41 is SDN from Hannington.

It is on exactly the same bearing as Oxford (183 degrees), Oxford being 28km and Hannington 82km!

As you're tuning in Oxford, when you run the automatic tuning scan, have the aerial unplugged up until 60% as all of Oxford's channels are above this. This should also prevent the receiver picking up pretty much all other channels in your area.

Dave L could this be the same issue for me, it does seem rather odd though that we can predict that we lose channel 62 as regular as clockwork about 9.15. I retune and it comes back, last night though it took two re-tunes.

You say all the Oxford channels are 60% in yet I get at least 21 about 30% in.

We are SN3 4ST

Robert - The percentages are not standardised across sets, and once you are well below 100 can vary greatly from place to place.

Something at 9:15 daily suggests interference on a timeswitch. Streetlights perhaps.

Robert: I don't think so.

The reason that I suggest unplugging the aerial lead for part of the scan is because the automatic tuning process may produce to "wrong" results, i.e. the set of channels that the receiver decides to use as the "main" ones are not those from the transmitter to which the aerial faces.

The first thing that is done during automatic tuning is to scan frequencies from low to high and see what's available. Having done this, the receiver needs to decide (where duplicates are found) which ones to use as the main ones. The rest are usually put in the 800s. It is the process by which the decision is made that can vary between receivers and hence the outcome of what any one device may choose to be the "main" set may vary to that of another device on the same aerial.

Having chosen "wrong" channels, the user is then watching a transmission broadcast from a transmitter other than the one which the aerial faces. So it's not surprising if poor reception does ensue. It is therefore necessary to, somehow, get the device tuned to the correct channels. The same issue could occur in the days of analogue with automatic tuning.

Where the wrong channels that the receiver decides to go with are outside of the range of those used by the desired transmitter, then a simple way around the problem is to unplug the aerial so the device never gets to "see" them during its scan.

If you click the Digital UK (DUK) Tradeview link next to your posting, it will bring up the DUK prediction for transmitters you may be able to receive. You say that you have some services by 30% of the scan. The scan runs from channels 21 to 69, so you can convert to percentage and vice versa. At 30% it has completed looking in the 20s and there is apparently one transmitter in that range which is Chiseldon.

Looking at the predictor for your location, if you do the unplugging aerial trick, then the channels used for Mendip are interleaved within those of Oxford.

What I would say is that it is perhaps good practice to check that the main channels are the desired ones. Refer to "After switchover configuration":

Freeview multiplexes | - independent free digital TV advice

Check the signal strength screen whilst on one of the services from each group (multiplex). Ensure that the UHF channel given is that of the desired transmitter and not another one.

As you have already done this, and confirmed it is channel 62, then this would appear not to be the issue (at least for this particular multiplex).

Robert: Could I request that the next time channel Ch62 drops out or indeed any of your other channels, that rather than immediately re-tuning the device in question just carry out a signal / quality level test on the blank screen, as the chances are that the signal will still be there but hovering at a level that's just under the reception threshold of your receiver, which of course results in the blank screen.

The reason I ask is that it would be interesting to know what this level is when compared to normal operation, as for satisfactory reception the "normal" would have to be considerably higher or the picture / audio would suffer from frequent intermittent glitching during the fluctuations in signal levels that occurs throughout a 24 hour period when dealing with any signals received from non line-of-site transmitters at reasonable distances away, in your case Oxford being at 27 miles and with Mendip being at 46 miles, although the latter falls well behind Oxford as far as reception predictions are concerned.

Just out of interest, what brand / model of device is the item in question? and does this particular problem also affect any other devices that might possibly use the same aerial system?

Yeah, I figured we were probably picking it up from another aerial, but we're getting 60% strength and 100% quality and a rock solid picture, so I'm tempted to leave it as it is at the moment.

Last time, I did a factory reset and then a manual tune of channel, which picked everything up from Oxford.

Anybody know why 62 is cutting out?

Those are not from Oxford, that's why they're weak at your location.
