Time and date radio signal

Has anyone any experience of using the radio signal transmitted by the national physical laboratory?

Hello,

This has been looked at several times in the past, try the old matrix forums and there should be some information there for you.

Thanks Ben. I'd read some of these and quite bit more on tinternet. The radio reception hardware required is huge compared to toehr electronic components. I was wondering how they did it with analogue clocks that you can buy. I might buy a cheap radio clock movement and take it apart to see how they achieve it in such a small unit
