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

It may also be worth mentioning, I only picked up on ch36 594000 a couple of days ago, and at that point, all the channels were fine, just yesterday and today that I have had a problem viewing them.

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 Freeview 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explanation on how to do a reset/retune (as there is elsewhere on this site) to ensure your system(s) is cleared of any out of date tuning information which can "confuse" some equipment and get the correct multiplexes from Mendip.
Some of you MAY require a new T-band/Wideband aerial where your old aerial doesn't provide an adequate signal for some of the new UHF channel allocations for the multiplexes. Links to the Freeview site give pages where you can get help and may qualify for a free aerial upgrade if you don't have cable and/or satellite.
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.

Hutton, being a relay, is very unlikely tpo have its power output changed.
Do you have a wideband aerial in use? If not you need to have one fitted. That is likely to be the cause of your problems.

Phil: According to Digital UK, the Hutton relay is changing frequencies and increasing power output on 19th June. You will likely need a new aerial (if your existing one isn't wideband) as the transmitter is changing from Group C/D to Group A frequencies. This should be available free of charge if you don't have satellite or cable.

1pm on 12th June, and a scan is showing nothing on ch36 594000 (com7 HD) again.
All the websites are reporting 100% signal/no problems.
Hopefully after the next retune it will settle down.

Since the recent update at the Mendip transmitter, we have a reduced signal quality. Resulting in the picture pixating and sound quality poor. My post code is NP26 5RN.

Have you had your aerial changed for a wideband type? If not, you need to have one fitted as several channl;es have changed frequency and there are nore changes expected next week.
