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

https://www.freeview.co.uk/corporate/platform-management/700mhz-clearance
https://www.freeview.co.uk/service-updates
https://www.freeview.co.uk/corporate/platform-management/planned-engineering-works
Freeview seem incapable of providing decent fault information so check this site (BBC) -
https://www.bbc.co.uk/reception/ or https://www.radioandtvhelp.co.uk/
https://www.freeview.co.uk/corporate/platform-management/channel-listings

For the Coverage Checker -
Go to https://www.freeview.co.uk/ 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 -
https://www.freeview.co.uk/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. -
https://www.freeview.co.uk/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.

HTH.

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

The Planned Engineering link now redirects correctly.
New pdf's with the 2020 clearance events are now available - including Yorkshire!!
However, the Yorkshire Region on the Detailed View page is still "not found"!

A lot of the Sony channels were moved by Sony to Local multiplexes back in the summer. If you aren't getting the Bristol TV channel at LCN7 then you can't be receiving the Local multiplex. You could try a manual retune on UHF30 to see if you can pick it up, but it's not available in all areas.

Some old links for the 700MHz clearance now redirect correctly. Also a tip when loading https://www.freeview.co.uk/corporate/platform-management/channel-listings - clear your browser cache first or simply press <ctrl>F5 to make sure it loads the current version - it may have updated the Film4+1/More4+1 changes sooner than I thought, it has already updated the E4+1 change. On the 20th there's apparently going to be a change for PBS America and a +1 variant.
