[time-nuts] Earth: An Oscillator and Frequency Standard

Hi Tom:

Thanks for the lab test report on the earth frequency standard.  Since 
there are a number of frequency/time standards that have much better 
performance I'd like to find a way to directly measure the performance 
of the earth standard.  I've thought about a telescope looking at stars 
or maybe a photo detector to look at the light from the closest star to 
the earth frequency standard.  Do  you have any ideas on how to make 
these measurements?

Have Fun,

Brooke Clarke
