[KX3} Accuracy of clock

Gary Hawkins
Hi all,

Does anyone know how accurate is the clock on KX3?  The reason I ask is
because I activated a local SOTA peak last weekend and did another peak
this weekend.  After setting the clock accurately last weekend, I did
not think about checking it this weekend but half way through this
weekend's activation I noticed my UTC time setting was 1hr and 17 mins
off!  While it was easy enough to correct the log, is the clock expected
to drift this much in a week?

Aside, from this KX3 working really well on the hills with AlexLoop.

Thanks in appreciation,

Gary KK6GXD

Gary,

I can't answer for the accuracy of the clock, but if I depended on the
accuracy of the clock, I would set it just prior to any outing. The
short term accuracy should be sufficient for logging, but the long term
accuracy may not be so great.

Compare it to a computer clock.  There is a reason that the computer OS
re-syncs the clock with a NIST time standard occasionally - that
compensates for drift in the clock.  With the KX3 (or other transceiver
clocks), you must do that manually.
