Time-Nuts -- Precise Time and Frequency for Amateurs

Description

Time-Nuts™ is a mailing list for amateurs who are interested in precise Time & Frequency. Topics include stability of quartz oscillators, measurements of rubidium and cesium atomic clocks, using WWVB, Loran-C, and GPS for long-term comparisons.

Most of the members are hams or electronics hobbyists. Topics also include acquisition, repair, and operation of surplus electronic instruments related to precise time; nanoseconds; picoseconds; results of homebrew hardware and software T&F projects, etc.

Please join if you have questions or expertise to add to the group. The time-nuts main page and archive is at: https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts.

Getting Started with Amateur Time & Frequency

If you have an interest in precise time & frequency or are getting the "time bug" here are some suggestions:

History of Time-Nuts

In the pre-web 1990s Tom Clark set up a gps-timing mailing list at NASA for those interested in his pioneering work with the Motorola Oncore-series GPS receiver. That list was an inspirational example of one man freely sharing a wealth of experience and information with a group of interested GPS timing newbies. The list was specific to his home-brew TAC hardware (now TAC-2) and SHOWTIME software (now TAC32). The list moved to TACGPS and is still around but quiet (now hosted by TAPR).

However, there were other precise time & frequency topics not covered by tacgps. Over the years several of us - tvb, DougH, StanP, CorbyD, JohnA, BrookeC - were exchanging private emails that I thought deserved wider audience, participation, and archiving. So in 2001 time-nuts began. It was once cesium-nuts at Yahoo, then time-nuts here at LeapSecond.com, then John Ackermann graciously offered to administer and host it on his site so that's where it is today. [1] [2] [3] [4]
