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.

To all the above texting in about difficulties just recently no it is not a fault at the main it is atmospheric conditions or simply an which are causing signals to pixellate,break up and even disappear into "" .KMJ, above hit the nail on the head.Also have any of the above while experiencing these difficulties been able to receive temporarily alien UK or foreign European transmissions as such,when they rescan as one simple remedy when these weather related transmission difficulties occur is to rescan your TV/set-top box either automatic or manual .If anybody receives unusual transmissions not normally associated with normal broadcasts from their home transmitter or mast,example Digitenne from Holland on fr 32 as an example i encountered on Sunday night myself (13 Nov 2011) or a different UK transmitter then its atmospherics/inversion that is the cause and until low pressure weather systems sweep in the condition will adhere more or less until the weather changes such as rain for example.Until the UK totally switches to by Wednesday 24 October 2012,these problems will more or less continue until then although hopefully once totally disappears from UK transmissions altogether these inversion issues will be less of a problem and possibly disappears (not guaranteed ?) completely in an all digital UK wide TV !

Richard,.Yes it is the wrong type of weather as you phrased it,look up that is the cause or difficulties you and a lot of people are encountering in most of eastern UK the last few days or so.I suffered with inversion myself on Sunday night (13 Nov 2011) not my local transmitter, (BBCA,D3+4,SDN mux's).So until rain sweeps in soon the inversion effect will more or less continue until low pressure sweeps in.

Hello all,

I'm on ground floor of 2 storey flats with communal aerial. Using Toshiba FView HD Recorder & Samsung TV. Postcode is KT11 3HA
Neighbours have so not affected.

Will lost channels be a prob till Apr 2012? Will buying help? Any one else local affected?

Thanks in advance for your advice.

CP problems in DA3

I doubt its the weather, looks more like something to do with the mux identifiers.
Appears to affect the more marginal reception areas so probably is not apparent to any tests they do at the .

Signal strength is around 1/2 as per normal but is very low on all .
is unaffected.

Stays like this until a rescan where it finds all the channels as before but they now have full quality, and work normally

This is the same on multiple different tvs in the household.
