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?

My ITV and Ch 4 etc reception in Sutton Courtenay is "Poor" all of the time and often breaks up but for last few days when I switch TV on in morning it says new channels found. ITV then shows NO signal and I have to rescan and get normal poor ITV channel again. Today however, after rescanning no ITV, Ch 4 etc signal at all. Presumably something being done at transmitter yet again.....will be glad when signal strength increase anf I can actually watch ITV properly.

I ran through problem troubleshooter which indicated probably due to weather - high pressure. Rescanned TV again this morning and channels back again, albeit with usual poor signal and pixelation on ITV, Ch 5 etc. Reception on other freeview boxes we have also poorer than normal.
When power levels are eventually increased at switchover, will this solve my poor signal problems on ITV etc and reduce likelihood of weather related problems?
I hope so as watching ITV on analogure will no longer be an option!

Have just turned TV on again and no signal, no ITV1, Ch4 or Ch 5 etc after rescan. Worked ok at circa 8 o/c this morning so presumably weather causing this problem again. Very frustrating.

MH: Check that the TV is actually tuning in C68 and not a distant version on a lower channel. The switchovers at Sandy Heath, Ridge Hill, Lark Stoke, Bromsgrove and The Wrekin mean there are now some pretty loud transmissions off to the sides, and if the weather conditions are right, the signal could be strong enough to be detectable, but not usable.

There should be a 'signal detection' menu somewhere which shows the UHF channel being used. If it's not C68, delete all the Mux 2 channels and do a manual retune on C68.

You are pretty close to the Oxford transmitter. An amplifier or booster will likely cause too much signal. Some people have found that the switch to the new aerial increased the signal levels and caused problems - if you don't have a booster, or removing it doesn't help, try adding an attenuator. 'Herringbone' patterns on analogue are an indication of having too much signal. All analogue channels should be perfectly clear at your location (certainly the first four), unless there is a problem with terrain, buildings or trees.

At switchover, the ITV1/C4 digital multiplex moves to C60, currently occupied by ITV1 analogue. There should be fewer problems.

Mike, thanks for your feedback. I have just rescanned and TV is tuning to C68 with ITV1 & Ch5 etc now found but usual poor signal & fairly constant pixelation. Not using booster, and had new roof aerial fitted circa 2 years ago. Analogue channels very good. Just have to hope that things improve at switchover on C60. Fingers crossed.

I'm in Swindon, and receive my freeview from the Oxford transmitter.

Reception has recently become almost unwatchable for most of the day, on most channels. No end of retuning will return reception to the channels that were previously crystal clear ..... How can I tell if I have a wideband aerial? The aerial on my house is likely to be 10-15 years old.

Do I need to change my aerial?

I guess the trees must have come out in leaf now and are attenuating high channel signal strength - my latest reception at OX28, East Witney with a very old Group C/D antenna, is:

Ch 29 (MuxD) - Very good
Ch 34 (Mux1) - Very good
Ch 48 (MuxC) - Good
Ch 51 (MuxA) - Medium/Good (was Good)
Ch 52 (MuxB) - Good
Ch 68 (Mux2) - Poor/Medium (was Medium)

Fortunately the picture quality doesn't seem any worse than before though - it's just the reported signal quality.
