I'm using Meinberrg NTP and Windows ten.  No problems here.

Interesting.  The same issue exists in running WSPR.  I have been using
Dimension4 (on an XP and Win7 machine) at home with good luck.  I was
running a 17 m WSPR beacon at K3NAL on base and received a couple of emails
indicating that my timing was grossly off.  Since there is no internet
available at the station, I had to "hack" the time with WWV or Dominion
Observatory Canada, but it soon drifts off.

Tom, DL2WB, who reported my problem initially, described his system of
syncing the time using a GPS receiver.  I now have a $16 GPS kit in work on
my bench and hope to have it going soon!  Another possibility is the
Rubidium time standard ( so-called atomic clock) in the next room!   50 feet
of RG-59 to bring the 1 PPS time code to the rig might solve all my
problems.

I've been reading about JT65 and each article states that computer time has
to be set accurately.  They all say Windoze time sync is not accurate
enough.  I have used Dimension 4 in the past to set computer time.

So... what are you using for time sync?

Any suggestions on JT65 software would be appreciated especially any that
can be used with HRD.
