Hi John,
The clock's accuracy is typically +/- 2 seconds per day. If that
doesn't suffice for a long trip, and you don't have a timepiece to
correlate it to, you could attempt to adjust the frequency of the
clock crystal closer to 32768 Hz. This usually requires some long-term
experimentat
Time set is in the config menu. It is on page 53 in my manual. It is not easy
to figure out, but activate the Config menu, find TIME with the VFO
B knob. Tap 1 for hours, 2 for minutes, 3 for seconds then rotate the VFO A
knob to change the number. If your problem is finding the correct time
My clock runs about 15 seconds fast by the end of summer, and this is
made up by the following spring in my sometimes heated ham shack. The
annual error is very small. But temperature is a factor. I
originally thought that all frequencies on the K3 would be controlled
by the TCXO, but, o

The TCXO has no relation to the K3's real-time clock, which has its
own crystal. Neat idea, though :) Of course the RTC is powered at all
times, even with the rig is off, via its own 3-V battery. The TXCO is
powered down when the rig is off.

I'm curious which way the clock is off, fast or slow?
There is a dedicated clock IC on the front panel board which has a
fixed capacitor across the 32.768 KHz crystal. The data sheet for
the PCF8563 clock IC states that that capicator can made a trimmer to
set the frequency exactly. Of course

The coin battery is not recharged - it operates standalone. It will

That far out. Looks like you are only half as accurate as my wristwatch.
The clock on my K3 isn't terribly accurate either. But I've since learned
how to deal with it. Pretty much every piece of electronics you buy these

It is a series of K3 commands. The K3 utility emulates what you would do from

open the config:time menu, DS to read the VFO A display, and UP and DN to
change the hours, minutes, and seconds to match your time source.
