[SMCARA] [Non-DoD Source] JT65

[Clarke, Tom AIR4.0P NATOPS]

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.
