GoKawiilTime-Nuts mailing list serves 1,800 precision timing hobbyists
Time-Nuts is a mailing list hosted at lists.febo.com for amateurs focused on precise time and frequency measurement, covering quartz oscillator stability, rubidium and cesium atomic clocks, and signals like WWVB, Loran-C and GPS. The list has about 1,800 members, mostly hams and electronics hobbyists, who also discuss repairing surplus timing instruments and homebrew hardware/software projects. An archive of posts from 2004 onward is available at febo.com/pipermail.
GoKawiil's interpretation of the reporting above, not reported fact.
The list's persistence and size suggest a durable niche community of hobbyists bridging amateur radio and metrology, where expertise in nanosecond-level timing is shared outside formal institutions. Such grassroots groups can serve as informal knowledge repositories for skills increasingly rare in commercial or academic settings.
- Time-Nuts has roughly 1,800 subscribers interested in precision time and frequency topics.
- Discussions cover atomic clocks, GPS/WWVB/Loran-C timing signals, and surplus instrument repair.
- A public archive of list messages dating back to 2004 is hosted on febo.com.
Leo Bodnar GPS Frequency Reference — This GPS-disciplined oscillator is a favorite among time-nuts hobbyists for generating highly stable, traceable frequency references right at home. It pairs perfectly with the kind of homebrew timing and frequency experiments discussed on the list, letting you compare your own oscillators against a GPS-locked standard.
