[Elecraft] Clock accuracy and JT-65

2016-08-28 Thread John R. Lonigro
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 accu

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

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 an
