KX3 Accuracy of clock

Yep, mine drifts and I’ve had it up to a couple of minutes off. Surprisingly, for a week’s time, it can be about a minute or so off. I will pay more attention and keep track.

Re: KX3 Accuracy of clock

I wonder how easy/hard it would be to have the radio poll 10Mhz (like the
atomic clocks do) every so often when powered on, to keep the time more
accurately. That would be a pretty cool feature.

Re: KX3 Accuracy of clock

Actually ... "atomic clocks" such as the UTC one hanging on the wall of
my shack [that I won at radio club raffle] don't "poll 10MHz." They
listen for WWVB on 60KHz, which mine hears only at night here in CA.
WWVB broadcasts a continuous IRIG-H time code with a somewhat obscure AM
modulation scheme [they recently added the same time code using a phase
modulation scheme *very* loosely resembling PSK-31]. Doing this in the
K3 would require a 60KHz receiver, demodulator, decoder, and probably a
ferrite antenna.

Whether or not mine updates at night depends on a number of factors, not
the least of which is ambient noise. It usually is in sync with WWV on
any of the MF and HF frequencies, but that's not guaranteed, I just
checked and it's about 35 secs slow now. My dive watch does vastly
better. :-)

I volunteer at the local blood bank and recording times is important to
the documentation of the process. Consequently, they installed "atomic
clocks", our little center has 5 of them, not all the same mfr,
scattered around to be visible to the staff. I've watched them differ
by more than 90 seconds at times, and rarely are any two of them in sync.

I assume my K3 runs the clock [which I never use] off the one of the
processor clocks. I recently built a 40-station irrigation controller
for my wife [we live on 5 acres and she's a kamikaze gardener] using the
Hamstack components. Their C-library includes a clock adjustment
capability. I have two separate CPU's, one is a little fast and one is
just a tad slow. I now have them adjusted so they're within a second or
two of each other after a month or so. Maybe the K3 could include
something like that, accessible through the K3 Utility?

Firmware that decoded the BCD encoded by wwv on HF would be a pretty

I confess that I am an "exact time" freak and sadly the several WWVB
clocks I have tried here don't get enough of a signal to sync. I have
investigated a wall clock that syncs with a time standard on the
internet via an ethernet connection just like the clock in my
computer(s) - a very beautiful one with 5" high digits showing hours,
minutes, and seconds. Too bad it doesn't have tri-color LEDs that would
be red during the CW silent period, green during the 'phone silent
period, and some other color at other times. That is what I would want
for a digital clock that costs $500. If my present analog "ship radio
room" quartz clock dies, I may reconsider it.

Re: KX3 Accuracy of clock

For those Windows users who wish to keep their computer clocks accurate,
I would suggest Atomic Clock Sync -
http://www.download366.com/atomic-clock-sync?utm_source=bing&utm_medium=cpc&utm_campaign=366_USA_en_longtail_Gestores&utm_content=Atomic-Clock-Sync&utm_term=Atomic%20Clock%20Sync

I have enjoyed its accuracy for several years. Free to use.

Looks like my malware-detector - VIPRE Internet Security 2013 - didn't
like your URL. It does it every now and then and hides what it removes
but I was able to examine it - looks like VIPRE doesn't like long
involved URLs.

However, in both Win XP and Win 7 (don't know about Win 8) the OS has a
time sync default of once a week but one can set the sync interval to
another value by judicious hack...err, editing of the Registry. I have
mine set to sync hourly - overkill perhaps but that's what I do.
Remnants of the old "keep alive" procedures of dial-up days. Keeps my
K2 operation on time as well.

Re: KX3 Accuracy of clock

In reply to this post by Don Wilhelm-4

Even the native Win7 implementation is defective, updating only once every few days and not using the differences to make corrections between updates.

Since I run HRD (running 24/7) and it has an NTP client in the DM780 program, I use that. But I will look at what the others have posted too.

Remember: the JT modes require an accurate clock (on the computer, not the radio).

Try this:

1. Start the *Registry Editor*
2. Go to *HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services
\ W32Time \ TimeProviders \ NtpClient \*
3. Double-click the *SpecialPollInterval* value, and change the Base
of the *Value data* to *Decimal*
4. Now change the *Value data* to the time interval you desire,
noting that the time is given in seconds (so for 1 day the value
would be *86400*, while the default (7 days) is *604800*
5. Close the registry editor

I set my Windows 7 interval at 3600 (1 hour).

Warning - as my son the IT specialist says of Registry modifications
"Danger - There Be Dragons". Back up the Registry before proceeding and
if you are skittish about such surgery, don't do it.

Re: KX3 Accuracy of clock

On Debian Linux and derivatives (Ubuntu and its variants, Mint and its
variants, etc.) install the ntp package, sit back, and enjoy. The
default configuration starts the daemon with a set of four NTP servers
defined and no editing of a config file is necessary unless one has a
local NTP server to sync to, etc.

Re: KX3 Accuracy of clock

In reply to this post by Esquer Dave

Not sure how all this commentary on computer time applies to the
topic title. My KX3 keeps perfect time since I did not buy the
battery charger...no clock! My $12 wrist watch has about 1
second/year accuracy.

The K3 clock drifts over a week or so, but is easily corrected using
the Utility program (on my computer).

My computer time is maintained by D4, which is a free download with
no tinkering of registry required. Install it, chose a time source
and forget it. I use tick.uso.navy.mil and pole it every minute
(which is admittedly excessive). For JT65 poling probably every ten
minutes or a couple times per hour would be adequate (time needs to
be <1 second error; mine never exceeds 0.020 second error).

For the very time-obsessed, build and operate your own GPS-controlled
NTP time server as described here:

<http://open.konspyre.org/blog/2012/10/18/raspberry-pi-time-server/>

Yes, I admit, I have one of these serving network time here in my shack
or "laboratory" as my 8 year old son calls it. :)

At one time it was even worse - I had a GPS-disciplined 10 MHz frequency
standard... ;)

I actually built one from an Arduino before. It's accurate within
milliseconds (which is enough for JT65), but I'm sure it could be made
better. (Source code at https://github.com/tmiw/arduino-ntpd if interested.)

In reply to this post by Esquer Dave

I have had my KX3 since the beginning of the year and I have not reset
the clock since, and it is now 4 minutes ahead of the actual time. I'll
leave it until next year and see how it goes.
May I wish everyone a Merry Christmas and a Happy New Year.

Re: KX3 Accuracy of clock

In reply to this post by Edward R Cole

I checked the time on my kx3 last night. After 5 weeks it hasn't changed or
maybe a few seconds. Did I get the bad one out of the batch!

Re: KX3 Accuracy of clock

I guess I have never understood why a clock on a radio was important. I guess unless you use it for automatic wake up or something. But, the one clock I wish I had was the clock for my old Hammarlund HQ-170A which needs a clock. I would never use it, it just needs to fill the space.

I hate clocks on appliances. We have three digital clock read outs on our appliances in the kitchen (microwave, stove/oven, and fridge) and it is impossible to keep them all the same time. Having them different bugs me to no end. And, I prefer they did not exist.

But, isn't the clock on the KX3 a mere side effect and not a front line feature. I mean, the battery charger needs a clock for those timed charge intervals but who would use the KX3 clock readout.

OK, off of my soapbox drivel...

Re: KX3 Accuracy of clock

Phil,

I, for one, use the KX3 clock readout every time I'm on a summit in subzero wind chills and my wristwatch is buried inside my heavy parka. Paper and pencil logging is hard enough in adverse field conditions, but having the clock right on the face of the KX3 helps a lot! The KX3 clock is very easy to set in the warmth of the car at the trailhead and maintains excellent accuracy for the several hours needed for the climb, activation, and descent.
