[Elecraft] Clock accuracy and JT-65
As I understand it, JT65 requires a highly accurate clock, accurate to less than a second. However, unless the KX3 is capable of encoding/decoding JT65, that accuracy is required in the computer doing the encoding/decoding, not the radio. Sure, it would be nice if the KX3 clock were more accurate, but I can't see what practical use that feature would have, other than preventing you from jumping the gun at Field Day. And setting the clock the night before Field Day would solve that problem. 73, John AA0VE __ 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

There are various automated schemes for making sure that the computer clock is accurate; some have been discussed on this forum in the past. With Windows 8 and later you can sync manually with government time standards by clicking on the time in the lower right of the taskbar and working through the menus.

Re: [Elecraft] Clock accuracy and JT-65
do NOT trust Windows to set time accurately (and only once a day too). They've mangled NTP so badly that it has a five minute accuracy window... if you want your computer to be accurate, replace the MS client with Meinburg. Mine stays within a few milliseconds now, easily close enough for ham tasks. Rick nhc On 8/29/2016 8:40 AM, Tony Estep wrote: On Sun, Aug 28, 2016 at 4:30 PM, John R.

Re: [Elecraft] Clock accuracy and JT-65
Hi all, I couldn't agree more. I have had Meinberg NTP on both my computers for a decade or more and it works perfectly. While I can't tell that it is ms accurate (I have no doubt that it is) but it is certainly totally synced to WWV as determined by the ear and eyes. Just Google it, install it and use it. What MS supplies with Windows is junk.
