Thanks Dave.   I disabled the computer automatically correcting the time in
the time and date window of Windows Xp, but alas, no luck.  I guess I will
just have to live with not using the GPS to set the computer clock.

Hi James,

 

I had a similar problem with Vista. I had "set computer time " set to enable
.. After a period of time  (hour to days ) Winsdr  would start to produce
errors   and then crash. There is some kind of conflict between the GPS
derived time and the Windows operating system. My fix was to disable the
"set computer time" function and let the Winsdr time be independent of the
computer time and use the internet time on the computer. The data is tagged
with the GPS time so there is no error in the seismic data. 

 

I have been told  by Angel that Vista does not allow  the time to be set by
any source other than manual or internet time services .

 

I admit I don't fully understand the interaction but Vista has this and many
other frustrating idiosyncrasies.  I did  not have this problem with the XP
home edition .

 

Dave

I will try turning off Windows time service and see if that solves the
problem.  Thanks

Everything else works fine with WinSDR.

Hi James,

 

Windows has a service called "Windows Time Service" that tries to keep your
computer time.  Maybe it is doing just that and you end up with packets with
weird timestamps.  Just a thought.

 

You can turn off this service.

 

regards,
