[time-nuts] Loran C shutdown

[Brooke Clarke]

Hi:

As the distance between the transmitter and receiver increases so does the 
jitter in the received signal.   You can see that in the data on the NIST page 
where they monitor different stations from Colorado.  The greater the distance 
the poorer the time recovered.

Have Fun,

Brooke Clarke
