Re: DROP OUT OF DATA WHEN GPS CORRECTS TIME IN WINSDRHi 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.=20

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 .

    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,
