I implemented a PID in software and after a little experimenting with the gain parameters, I'm able to get and maintain sync. There is a little oscillation, but it's within about 20 PPM, which is within the noise of my system. Thanks for pointing me the right direction. _______________________________________________ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions
