flex1500 and JT65 Time Loss

Running PowerSDR 2.7.2, JT65HF, Flexradio 1500, and Windows 7 Professional, 64 bit.  Have system clock synchronized thru Network Time Synchorization which updates every 15 minutes.  Time sync on the PC appears to be very accurate.  When running this configuration, "DT values" on the JT65 screen continue to get longer over time (1.5 - 6 seconds over 24 hours).  The current solution is to "Stop" PowerSDR 2.7.2, and then "Start" it again.  I don't have to reboot or anything, just hit the "Stop" button and then "Start." It seems to reset the clock and all is well for a while.  Is there a solution for this problem?

    Mike,

    I had a problem similar to this using the VAC software from Eugene Muzychenko. I solved it by switching to VB-Cable (free).

    Ed.  Thanks.  I am currently using VAC software from Eugene.  I will switch to VB-Cable when I get a chance....Once again, "the devil is in the details."

    Did you "buy" vac? The download has limitations unless you purchase it. I am using it with Dimension 4 time software, much better than Microsoft's time app. And free Keith w7zac

    Yes.  I bought vac.....and am using NetTime 3.14 to time synchronize over ethernet.  The time sync software seems to work great.......
