5147Re: [wsjtgroup] Clock sync
- Sep 4, 2008I used to run D4 with my old XP Dell PC. I needed to have the time updated
every 5 minutes in order to have the correct time.
After changing to "Windows Vista" I no longer use D4. I have the operating
system reset my clock every 4 hours. The new PC keeps very accurate time.
(It is a Dell also but much better than the old one) The better clock
probably not a function of the operating system???
For information on how to set up the paramemeters using windows Vista, see
Vista default is 7 days. I suggest following the directions and setting the
time sync update interval to every hour. If not often enough, then adjust as
needed. I no longer use D4 thus one less application open!
Works for me. XP automatic time update was a weak link, Vista much better!
