The symbol shows the location of the Sudbury (Suffolk, England) transmitter which serves 440,000 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 Sudbury (Suffolk, England) mast?

Thnak you for a very succinct explanation of what has happened and the reasons behind it.
However I'm sure we're all equally shocked and distgusted that the transmitter engineers are able to do this, let alone without any prior warning or explanation, having already gone though a campaign to 'switchover' in the July - there was never anything said then that what need in July must be suitable for 'lower strength' signal coming in November.
How do I raise a complaint to these people - just directly with OFCOM?

Neil,
This was known about before the switchover; it was being talked about by Mike Dimmick on the 28th June, for instance. I think that it isn't the engineers' fault, but the fault of the people providing the information about the switchover.
To be honest, I'm a bit surprised that Briantist hasn't updated the info at the top of the page to show the true existing channels or the final timescale. It would save a lot of people being very confused because they just want to know what channels to search for and they don't have the time or knowledge to go back through 10 pages of posts about MUXes, modes, powers etc.

Panasonic Diga VHS/DVD recorder - DMR-EZ49VEB
We are also on the Sudbury transmitter.
When I recently purchased the DMR-EZ49VEB VHS/DVD recorder it displayed all the TV channels after setup. Yet since carrying out a 'New Channel' update recently I can no longer get Film4 or the Yesterday channels to show in the TV Guide+ listing. I have re-tuned automatically and manually following both the manual book instructions and DigitalUK's instructions until I'm blue in the face. But still they will not show.
Am I doing something wrong?
By the way, both Film4 and the Yesterday channels show up fine on the TX-32LXD700 TV and the DMR-EX89EB DVD recorder, with excellent picture quality. So I am obviously receiving a good signal.
HELP please!!

Stephen: Well, as the saying goes, two out of three ain't bad.
Bearing in mind that there are lots of people that can't get these channels now, you are doing well.
Not all devices are of equal sensitivity.
You could take the VHS/DVD to another aerial socket if you have one; or plug it straight into the aerial outlet if it's via another device or extension lead.
Or try wiping the tuned channels on the VHS/DVD and manually tuning them all, doing C63 first.

Two out of three isn't bad. But when you have had three out of three and lose one you tend to notice these little things.

Stephen,
Try swapping devices between rooms, if they are being used in different rooms. Pr swap the aerial leads around - some devices are more sensitive to signal loss than others and looping through another device rarely improves the signal level. Consider having custom leads made up with quality wire - it's generally cheaper than buying new leads and the improvement is worth it.
If all else fails, wait until June 27th 2012 when there will be yet another retune and your Film4 signal should be readily received.

Stephen: Plus in addition to the very valid suggestion made by Norm De Plume, it should be pointed out that because some programmes can be received on one piece of equipment but not another does not mean that a good signal is being received, as a signal that's just and no more above the reception threshold of the receiving device gives exactly the same quality as one that's touching near to 100%, 95% or so being a safe level on most equipment to avoid any tendencies for intermittent signal overload situations to occur in its tuner, some tuners being more vulnerable to this than others.
If by any chance both recording devices are being used in the same location, then its not advisable to "daisy chain" the aerial feeds as this encourages the sort of problem you are experiencing, but feed the aerial into a three, or more common, four way powered splitter and have each device fed from that, as this arrangement guarantees that each device will be receiving exactly the same signal.
It would have been of assistance though to have had knowledge of your location (pref: post code) in relation to the Sudbury transmitter.

Norm De Plume and jb38
Thank you both for your advice.
My location is Maldon.
jb38. I think your reference to the daisy chain linking to all three units may be worth looking into.
I have only had the VHS/DVD recorder from new since the 22nd November. And all three freeview tuners were displaying all channels fine then using the aerial daisy chain method.
Oh well, I shall have a play around. otherwise I'll wait until June and see what happens.
If I get it sorted I'll let you know what the outcome was. Thanks again all.

Stephen: I agree with all the above, in addition I would suggest as fewer connections as possible between the aerial and TV. To this extent, where possible, I have the aerial lead coming directly out of the wall into the TV. This avoids the possibility of the lead being kinked in the aerail socket wall box. This approach is ideal where a wall mounted flat screen TV is used.

I live at Bures, 2.3km from the mast.
I have erected on the chimney a 36 element w/b Labgear yagi which has a 5 metre coax run to the TV in my upstairs workshop.
The reception is hopeless, some nights all the C63 channels are missing.
Even with an amp at the back of the set, the picture still pixelates.
Everyone in Bures is complaining.
