Are you able to verify the use of a rubidium source there?  Hardly any TV 
stations here use an atomic master reference, except in the very largest 
cities.

The major networks do, of course, but stations seldom pass network video 
directly these days.  In analog facilities, most sources are synchronized in 
the switcher, courtesy of digital frame sync circuitry locked to the 
station's master sync generator-- which generally has a TCXO at its heart.

It would be a delight to have rubidium-locked sync available on this side of 
the pond.
