To all the above texting in about reception difficulties just recently no it is not a transmitter fault at the main Crystal Palace mast it is atmospheric conditions or simply an inversion effect which are causing signals to pixellate,break up and even disappear into "No signal" mode.KMJ,Derby 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 scan.If anybody receives unusual transmissions not normally associated with normal broadcasts from their home transmitter or relay 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 digital by Wednesday 24 October 2012,these problems will more or less continue until then although hopefully once analogue 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 terrestrial UK wide TV !

Richard,Tunbridge Wells.Yes it is the wrong type of weather as you phrased it,look up inversion effect that is the cause or reception 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,Belmont (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.

Still absolutely 0 channels on freeview, thankfully I have an old sky box and dish to watch my tv through. Have tried many scans to no avail.
I replaced my old aerial with a new digi type and a signal booster about 18mths ago.
Should I still be having this problem or do I need to wait for the inversion effect to clear. Cheers guys for any help on this. (Crawley RH10).

Hello all,
My freeview service worked 100% perfect until 12 Nov now I have lost all HD channels and the others are varialable from day to day. Have re-tuned with aerial in / out, read thru the excellent advice here and contacted the digital switchover helpline. My switchover isn't till Apr 2012.

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

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

Thanks in advance for your advice.

CP reception problems in DA3

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


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