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?

I'm not sure what cooking has to do with anything on this site. Very strange

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.

alan: I find it a bit amazing that you are able to receive anything at all with the aerial set up mentioned when bring located at only two miles or so from a station containing multiplexes with an ERP of 100Kw, and so I can only assume that you are partially in an "under the umbrella" type of situation whereby being so close to the mast its main power output is radiating above you, as otherwise the tuner in your receiving device would be totally swamped by the signal thereby killing any chances of receiving anything, something many have experienced when their local stations switched to high power operation.
The point is, that tuners have a form of automatic gain control which reduces their sensitivity in strong signal situations, and trying to pick up a weak signal (i.e: Ch54 or Ch63) is made more difficult because the tuners wideband input circuitry will "still" sense the presence of high powered signal levels from the main muxes likewise it reducing its input sensitivity to avoid signal overloading problems, but which in turn reduces the chances of picking up weaker signals on other lesser mux channels, which it has to be said is really caused by the oddball situation at Sudbury, as I cant think of anywhere else operating with the same power differential level between the muxes. (albeit this being temporary)
You should really be trying experiments with a variable attenuator rather than boosting the signal, and although its a time consuming exercise you should scrub everything stored and try manual tuning of Ch54 or Ch63 with the attenuator set to various levels. Of course there is no guarantee that this would work either, as the reference to the "umbrella" effect can also be applied to the outputs from Muxes C / D, so its really a "hit and miss" situation that requires a level of experimenting in an attempt to effect a cure, if at all possible, as it isn't always!

any idea if the power is going to be increased on the sudbury transmitter for ch50 706.2mlz com6arq if ive got this wrong im orating fil4 itv4 viva etc etctalking about the group of channels with film4 viva itv4 etc etc .The watt output seems very low at only 1100

channel line up that was on 50 (channels you are after) are now on channel 63, I lost these at last re-tune, simon at Alpha aerials 01787 312822 was very helpful and very reasonable, now have all freeview back on all my t.v's
