[Elecraft] K3 timekeeping
I have no circuit diagram, what is the timebase quartz frekvency? 73' István HA4ZD __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] K3 Timekeeping
Thanks Wayne, Bill and Willis for your replies. I suppose the battery could be bad - but this has been a consistent problem since I assembled the Unit back in March. Could’ve been a bad battery out of the box I suppose. Willis - thanks for the perspective! Times have indeed changed (pun intended). I haven’t been accused of being young in quite some time! ;-) Wayne - I’ll check w/ customer support and see what they have to say. 73 all, and have a great Thanksgiving!

Re: [Elecraft] K3 Timekeeping
In general, we have seen a variance of this amount on the clock since we first started shipping K3s. Its in the normal range.

Re: [Elecraft] K3 Timekeeping
OK - Thanks Eric. Is there nothing the end-user can do to improve things - such as leaving power applied to the K3, etc?

Re: [Elecraft] K3 Timekeeping
I bought a big La Crosse wall clock that updates from WWV each night. Very easy to read and always accurate. I never look at the clock in the K2, KX3 and K3. Adding circuitry in the K3 to update its clock in a similar fashion might be doable, but not by me -- yet :-) 73, Phil W7OX On 11/26/14 2:36 PM, Arlen Fletcher wrote: OK - Thanks Eric.

Re: [Elecraft] K3 Timekeeping
Not that I can think of. The battery keeps it running when power is removed and its not particularly voltage sensitive. Swapping the crystal for the clock might change it a bit, but of course that could also go in the wrong direction. 73, Eric elecraft.com On 11/26/2014 2:36 PM, Arlen Fletcher wrote: OK - Thanks Eric.

[Elecraft] K3 Timekeeping
Every room here has a 60 kHZ-synched WWVB clock. Have never looked at ... or set ... the clocks in my K3 or KX3. Or the K2 if it has one. We have an actual clock radio in the bedroom. (;-) Trivia: The 60 kHZ xmtr NE of Fort Collins is a retired 100 kHZ LORAN C xmtr from ND. The last time I was there the 20 kHZ xmtr was an UGLY blue thing that had been hand-painted with a brush. 73 Ken Kopp - K0PP __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Re: [Elecraft] K3 Timekeeping
We don't do time changes here any more, always daylight saving time. Last time I reset the clock in the car was four years ago. It's currently 10 seconds slow.

Re: [Elecraft] K3 Timekeeping
I'm feeling lucky (quite rare). My KX3 (just checked) was ~20s off my NTP synced computers, and I set it about 3 months ago. I suppose it will drift more over time, but it sounds like there is variance that exists between units. How much do these clocks change over time in terms of cycles/accuracy? I'm not familiar with crystal based clocks and their operation by any means, hence the question, as reading some responses it sounds like it will change.
