Is it just me, or is it that the Mendip Transmitter seems to be the only main transmitter in the country to have all these problems? I regularly look at other transmitter locations on this site and am yet to see another transmitter post DSO to have all these problems!

Gareth Smart: At the moment, the Mendip transmitter is stuck betweeen regions that have fully switched (Wales, South West) and those that have not (Midlands, South).

This means that the commercial multiplexes here are at low power for a long time, as their frequencies are still in use for analogue services to the north and east.

This will happen to some other transmitters, but currently Mendip has had the worst of this.

Can I assume full power will be restored when the south and midlands (Sutton Coldfield?) switch? If so, do you know when this will happen?

David: it says at the top of the page, just under the transmission frequencies "NOTE: Mendip COM multiplexes will temporarily operate on channels 62+ for SDN, 56+ for Arqiva A, and 59+ for Arqiva B (all at 10kW ERP) until Autumn 2011. Final DSO channels will then be adopted, though ERP levels will remain limited until early 2012."

Basically it seems we don't get full power until next door (Meridian I think) switches in 2012.

Thanks for that Brian. I appreciate as well that Mendip is like it is until after our neighbouring regions have switched but sorry I am a COMPLETE amateur at all this but I am keen to learn, I appreciate as well the dates that the final channels will be adopted but it doesn't seem to tie in with either the Meridian or Central regions changing?

Also one more question please!?

My Aerial is facing towards Mendip and I did a re-tune the other day and am getting Fiver, FiveUS, ITV3, E4 etc from a UHF C51.

Anyone know which transmitter this is coming from?

Thanks in advance all
