Is NTP needed for PP

I’m trying to setup PP on my windows machine and wanted to know if NTP is really needed for PP? I tried to setup it up last night but was getting a lot of errors under the event window. Thanks for the help.

Why not ask on the PlanePlotter yahoo forum?

Have you seen

Yes you must run NTP to keep your timing accurate enough for the way PP does MLAT.

Thanks for the link.
