is the RTC implemented in the PIC chip?
i did not see a rtc chip in the prints...
The KXBC3 has no stand-alone RTC chip. Its PIC (U3) carries out
the RTC functions with an attached 32768 kHz crystal.
One should not expect great time-keeping accuracy from that.

That should be 32.768 kHz. :-)

Likely not -- until the regs
I think this might have been touched upon, but I wonder if a sw app
might be possible that would update the K3 clock from your computer
(say once per day)? Of course one can manually accomplish that using
the K3 utility.
For those of us whose K3 mainly stay in the shack and can be
connected
I use the clock on the K3. Mostly to keep time as I no longer have a

For myself, in relation to the KX3, I would appreciate an accurate clock so
that I could just grab and go knowing the time is correct without having to
check and reset. Especially important in portable operation, SOTA, etc.,
where one is often logging on paper. It's nice to keep the clock onscreen
Elecraft, Please give us a replacement clock chip that will keep time. An

I DO consider asking for an accurate clock in a ham radio transceiver a
'childish request'...
and
Elecraft, please do not pay any attention to these childish request
...
We have some riding their high horses here. :-)
Radio clocks that synch to LF or GPS signals seem to me gross overkill.
Given the tiny size of atomic clock / WWVB devices ... as in wrist
watches ... it would seem one could be integrated into both the K3 and KX3
and make the clock actually usable.

The original poster didn't tell us which radio, so I'm not sure how much
I care.
The clock in my KX3 works fine, and I can use the KX3 receiver to tune
in WWV (or any other time service around the world).
The typical battery powered atomic clock only checks the time service
every 4 to 6
I have a smart phone too (iPhone)
Unfortunately, it's not smart enough to realize that most of AZ is smart enough
to know that Daylight Savings Time doesn't really save any daylight, so we
don't mess with our clocks twice a year. So I either have to turn off automatic
updates and have it

That would be no good to me, Ken, WWVB is not receivable in Great Britain. We

Seems to me the answer may be simpler than trying to use VLF transmissions
for U.S. or U.K. atomic clocks. I think that technology is almost old hat
these days.
I have a golf watch that gives me yardages on just about any golf course
in the world, and it is all coordinated by GPS satellites.
Usable only in the part of the world where WWVB is
receivable.
