I'm in Wells, line of sight from my aerial to the .
I'm seeing nothing on ch51 714000 so I doubt what you are seeing is from .
ch36 594000 is very poor. A picks up all the , but HD ones don't play at all and SD ones are jerky.

ALL:

Please read various previous posts from p186 onwards from myself, MikeP, StevensOnln1 and some others which explain about the retune events, some of the bugs/errors on this site and give links to DigitalUK and pages where you can get the correct up-to-date & forthcoming change information. There's also explanation on how to do a reset/retune (as there is elsewhere on this site) to ensure your system(s) is cleared of any out of date tuning information which can "confuse" some equipment and get the correct multiplexes from .

Some of you MAY require a new T-band/ aerial where your old aerial doesn't provide an adequate for some of the new UHF channel allocations for the multiplexes. Links to the Freeview site give pages where you can get and may qualify for a free aerial if you don't have cable and/or .

For anyone on a communal aerial where others are having an identical problem not receiving some multiplexes, as already mentioned you will need to contact the manager of your complex for the distribution system and/or aerial to be checked/upgraded.

For anyone still having problems after following the previous links and advice, please post details of your problem and state which steps/advice you have already followed from previous posts and what happened.
