Like Bizman I am on the West Somerset coast and have had no problem except for a 3 second loss of signal during a heavy snow storm. Could the recent weather have something to do with it?

I Am having constant problems with pixelation from the mendip xmitter on my freeview. It doesn't seem to be dependent on weather and has been happening for several weeks now. I know other people in .Congresbury are having the same problem. Can anyone explain the problem or even a solution. I have tried retuning but to no avail.

@Bruce, without some local knowledge, geographic conditions, normal signal strength, signal quality, etc., I am unable to give an answer, sorry, but all I can say is what is not at fault.

Hi - do you know what time of day or night the 27th March retune should be done ? If you have a recorder set to record a BBC programme, it will be necessary to get the timing right won't it ?

Terry Cook: The deadline that they have set themselves is 6am. I wouldn't be surprised if it's sorted before then.

Have retuned several times this morning but still no BBC Channels. Anyone know when they're due back? Missing Radio 4 :-(
Thanks.

Alison: If you're receiving from Mendip then might you be using a communal aerial? Perhaps it needs adjustmet following the change of channel for BBC services.

In the mean time, Radio 4 is available to listen to over the internet or via FM, if you have an FM radio.

just how many more times are we going to have to update our receivers. I feel sure that there are many out there who, like me, are fed up. As an OAP who is able to update their sets, I feel sorry for those who are not 'tech savvy'. Digital, fetch back analogue at least we had a guaranteed service except when transmitters failed!
