[time-nuts] HP5065A on ebay

[Michael Wouters]

In Australia, fixed vehicle speed measurement devices, such as
piezoelectric loops buried in the road surface, are operated by the
state road transport authorities (the police operate mobile devices
such as handheld LIDARs). These have to be checked with some
(typically) purpose-built device which in turn must be calibrated,
using eg a calibrated rubidium standard. So there may also be some
legal traceability requirement that the Rb is used to satisfy.

Cheers
Michael.
