Ok, then it might be a better idea to use only it's 1 PPS output to count the frequency of the some other oscillator and build own steering electronics for that. Infact my original plan was to do right that. If the count/steering period is set long enough there should be any problem caused the satellite hopping or such things anymore. Let's say that if I make 24 hours running average for 10 MHz using Trimble's 1 PPS as a reference to determine the oscillator control then I would get the better results, right? But if LPRO is useless, which oscillator should I seek for main output? With low short therm drift and good phase noise characteristics etc? Also the goal is to build the reference with surplus (etc) parts as a hobby project, no interest to invest thousands for that. -- 73s!
