It's broadcast within the BBC HD Preview on Ch108, along with the Synch Test (at a different time within the Preview Loop).
Here is a
link to Andy Quested's Blog which contains instructions on how to use it. There are some comments/replies that told you where it was in terms of timings, but the Preview Lopp has changed since then



Although Andy's timings may still be valid irrespective of the Preview content.
It is very useful to try and find these 2 items, do a short instant recording of them, and save them for future use in a Folder.
