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.

Hi and thanks for your ideas.
A couple of things I should add, I have tried all of the resetting memory options but these have not worked. Specifically holding down the Menu button for 40 secs on the side of the TV had no effect.

The interesting thing is the TV works for hours with BBC frequency of 698000 kHz.it then seems to reset after changing channels to 794000kHz. Doing a manual retune seems odd to where after manually retuning to 698MHz and getting 22 channels, it defaults to "Discard" rather than "Store". Whereas when you do a full retune and finding 116 channels it defaults to "store".

All the other multiplexes seem to be unaffected.

Regards Chris

In Chippenham.

Lost a whole shed load of channels including itv4 & itv3. Does anyone know how long these interruptions will last?

Just watched This Mornings weather forecast and thought 'oh a different weather girl' then I realised the area covered was a bit further east, i.e. the Meridian area. This was later confirmed by the statement referring the 'weather for the Meridian region'. What happened there? Has Mendip run out of weather?

I don't have HD, I normally get weather and other regional content from West. This was just a one-off.
