[Elecraft] Clock Accuracy

[Edward R Cole]

Since I run mostly digital eme (JT65) my computer time accuracy needs 
are pretty strick (<1 second).  For years I used dimension 4 and 
switched to BktTimeSync (from IZ2BKT) last four years to utilize GPS 
time using a cheap USB dongle GPS unit.

BktTime can sync to NTP off the Internet or from a GPS.  Or have both 
running.  I run with NTP turned off and GPS Sync on startup so I do 
not need an Internet connection.  I have another computer for 
Internet/e-mail/loggers, etc.

Just booted the computer and got an update of 1.903000 seconds.  Next 
sync shifted time -0.027000 seconds.  I have it set for sync every 
ten minutes which keeps time within about 0.2 seconds which is more 
than adequate for synchronous digital modes (like JT65 or FT8).

I do not use the clock in my K3 so rarely update it.  Logging is 
manual using computer time.
