You can synchronize your laptop's internal clock with NTP by creating a Time Synchronization Task in the Task Scheduler of your W7/64 laptop. For ease of description and to save space here, please follow this link to learn how to do it. http://www.pretentiousname.com/timesync/index.html Also, you should change your laptop's Internet Time server to an NTP Internet Time Server that is more accurate than time.windows.com and is physically closer to your QTH.
