Some of the cited references are poor, modern non-linear mathematic is kind of omitted . After all the oscillator phase noise speculation, I would have really liked to see at last a reference about the most modern measurements techniques and it validation.

It was strange to hit "ctrl-f Rohde" and see only one reference in the bibliography. Same for "Hewlett." "Rubiola" brings up one hit (but no citations) and "Stein" brings up none at all. -- john, KE5FX Miles Design LLC _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

The reference [145] at the end of the sentence that mentions sapphire oscillators also discusses a hybrid photonic-microwave oscillator that incorporates a room-temperature sapphire oscillator so I think he tried to cover both subjects with that single reference. The paper has a misleading title. It suggests that it is a history of the last 50 years, when it is about events roughly 50 years ago. The abstract makes this clear though. So I didn't really expect to read much about developments past 1970.
