In Italy, the state-owned TV broadcaster RAI has all its timings locked to a 
central
Caesium standard, in Rome. Or at least so I have been told by a former RAI 
employee.
I'm wondering if some simple circuit diagram is to be found somewhere, to 
receive and
recover the synch timings, without using a real TV, bulky and noisy.
