[time-nuts] Tiny Atomic Clock

Hi John:

It's cool.  There is a major project in the U.S. military to develop a 
small and inexpensive clock.  There are a number of companies working on 
both Cs and Rb versions.  Note that the SINCGARs and Have Quick mil 
radios use frequency hopping, not for security, but for anti jam and 
anti DF reasons, and now use GPS receivers to set the clock in each 
radio.  If the radios had good clocks they would not need to be set so 
often.  This application also requires low power to keep the clock 
running.  So my guess is that these frequency standards are targeted for 
this application.

Have Fun,

Brooke Clarke, N6GCE
