Is there still transmitter engineering works ongoing at Mendip?
Experiencing weak signal on Mendip CH35 and CH36 multiplexes for week or so. All other multiplexes unaffected. Has transmitter power been fully restored to MAX?

AFAIK there's been no engineering work and none has been listed for the last couple of weeks. The six main muxes are all supposed to be transmitting at full power of 100kW. I'm not seeing any issues with UHF 35 & 36.
COMs 7&8 on UHF 55&56 transmit on less power than the others, but again all seems normal.

If you provide a full postcode, we can see what predicted reception at you location should be according to the DigitalUK checker.

allan smith: We need a full postcode, the coverage checkers don't work with place names or partial postcodes. In general, indoor aerials only work in areas with a strong signal (most a made up of little more than a piece of wire sticking out of an amplifier which picks up as much unwanted electrical noise as the wanted signal).

Allan Smith:

Knowing the area fairly well, I would suspect that it would be unreliable as it is a bit too far from the transmitter. You may get some reception but it would be quite variable. It would be far better to have a suitable outdoor aerial install at roof level and away from any water tanks and solar panels.

I live in Burnham on sea and I am not able to get channel 50.
Can you tell me why?

Please provide a full post code, then we can look up what services you should be getting. A partial post code is of no use as the Freeview system requires a full post code.

This isn't a reception problem but does anyone know what's happened to the Digital UK website? Several replies on this forum have directed users to this site, which contained a lot of useful info such as coverage checker, channel nos etc. Now a search for Digital UK appears to redirect to the Freeview website which doesn't contain anything useful in this respect.

John H:

Yes it has been amalgamated into the Freeview site and a very sloppy even bad job has been made of it, and some of the issues that I would have expected to have been fixed quickly have not.

The only old link that redirects correctly is the channel listings, but here is some links that will provide most of the useful information

Freeview | All your favourite TV shows, all in one place and all for free corporate/platform-management/700mhz-clearance">What is 700MHz clearance? | Freeview
Freeview | All your favourite TV shows, all in one place and all for free service-updates">Service updates | Freeview
Freeview | All your favourite TV shows, all in one place and all for free corporate/platform-management/planned-engineering-works">Planned engineering works | Freeview
Freeview seem incapable of providing decent fault information so check this site (BBC) -
Welcome to BBC Reception Advice | Help receiving TV and radio or Advice about receiving TV and radio | RTIS
Freeview | All your favourite TV shows, all in one place and all for free corporate/platform-management/channel-listings">Channel listings | Freeview

For the Coverage Checker -
Go to Freeview | All your favourite TV shows, all in one place and all for free scroll down the page to the box "Check Freeview at my home" and enter your postcode and house number/name. Scroll down the following page where available channels are shown in "tiles". Below the initial block there is a "down arrow" if not all are displayed. But if you are only interested in one group of channels click on that button on the top row.
If you scroll down just after half way down the page, there is a button "Detailed view". If you click on that it will show the predicted reception of transmitters and multiplexes that may be receivable at your location.

It's not currently possible to get/derive links for specific postcode predictions but there's a long winded work around for a given postcode. At the top of the Detailed View page there is a button for "View Region". If you select that (for the region for the postcode) it will give a url with postcode (and house number if provided) which is of the form -
Freeview | All your favourite TV shows, all in one place and all for free help/coverage-checker/detailed-view/west?postcode=bs35%202yj&address=80
To get to the predicted reception for that address, scroll down the page slightly and click on "Summary view". Scroll just over halfway down the new page and click on "Detailed view". It will now display all the transmitters and multiplexes that are predicted to give some reception at your location.
The only advantage I can see for this method is so others might be able to look at exactly what you've looked at, because otherwise they may as well check for themselves using the instructions in the previous paragraph.
NOTE: The Yorkshire Region information is not working at time of posting and wasn't last I checked when it was DigitalUK. (The pdf for Yorkshire clearance events wasn't working either last I checked!).
It does seem that Region pages can be accessed from a cut-down of the above example link, eg. -
Freeview | All your favourite TV shows, all in one place and all for free help/coverage-checker/detailed-view/west
For other regions, replace "west" with the relevant region name eg. central, wales, etc.
However I have discovered some inaccurate information on some of the above pages.

Thanks to Chris SE for the full reply, amongst other things I'd missed the "detailed view" button.
