Brian Gaff explained :
Ther are supposed to be some frequency shifted mod signals on the Long Wave
stations run by the bbc and some others. There is the time standards in the
UK and Germany used by radio clocks as well, but these are on a very low
frequency and I've not seen any direct display receivers about at affordable
costs.

The radio clocks and watches receive the VLF time standards.
