The next WWV ARC general meeting will be Thursday, March 23, 2023 at 6pm MST via Zoom.

Our featured guest is Dr. Jeffrey Sherman, NIST Boulder, with his talk "Atomic clocks and time keeping at NIST" - a pretty broad topic!  He'll talk about the physical basis for atomic timekeeping, and the fundamental role time has in most of precision metrology. He'll describe how the international time scale UTC is realized, and how laboratories like NIST contribute. He'll give a broad overview of activities at the NIST Time and Frequency Division, highlighting some important current themes: increased availability of high precision time signals from NIST, and a worldwide campaign to redefine the unit of the SI second in terms of an optical atomic transition.

Jeff Sherman received a Ph.D. in Physics from the University of Washington and came to NIST in 2009 to work on optical atomic frequency references and laser stabilization. His tenure at NIST has included work on NIST's Internet Time Service, and the ensemble time scale of atomic clocks comprising the official source of time and frequency signals, UTC(NIST).

This should be a good one!  Don't miss this meeting!

WW0WWV Special Event Station March 6-12:  The WWV Amateur Radio Club, in Fort Collins, Colorado, will be putting the club call, WW0WWV, on the air starting March 6 at 0000 UTC through March 12, 2359 UTC, 2023. We will be commemorating the 100th anniversary of standard frequency broadcasts from station WWV in Fort Collins which started March 6, 1923

We plan to have club members across the US operate on 80-10 meters, including the WARC bands, on CW, SSB and digital modes. Potentially other bands and even satellite QSLs will be available. Please see our page on

We look forward to seeing your call in the WW0WWV log!

If you are a current member, be aware that memberships are for the calendar year.  We kindly ask that you renew at the following link.

If you are not a member, please consider joining our club to help support our efforts to bring awareness to WWV and spread information about the station.  You can join using this link.


December 10, 2022 -Fort Collins, CO

The WWV ARC was created in January 2019 to celebrate the 100th Anniversary of the establishment of NIST Radio Station WWV, now located near Fort Collins, Colorado.  After the very successful October 2019 anniversary SES, several of the organizers kept the club loosely together and in the fall of 2020 discussions of re-writing the by-laws got rolling.  We registered with the State of Colorado as a non-profit in December 2020, and in April 2021 we established new by-laws and elected a re-organized Board.  WWV ARC is a recognized ARRL affiliated club as of May 28, 2021.  General membership opened in late summer 2021, and we are approaching the end of our first full year plus a few months.

We look forward to exploring and supporting a variety of amateur radio topics, citizen science amateur radio initiatives, metrology themes and issues, historical ties between amateur radio and NIST, as well as continued support for radio stations WWV, WWVB, and WWVH and the NIST Time and Frequency services.

Tune In: The WWV Frequency Celebration

The WWV Amateur Radio Club, along with the National Institute of Science and Technology (NIST), HamSCI (, and the Fort Collins Museum of Discovery ( are celebrating 100 years of standard frequency broadcasts from Radio Station WWV.  We're calling the event Tune In: The WWV Frequency Celebration, which will encompass historic and scientific WWV themed talks, tours, and a WWV Day at the museum on Saturday, March 4, 2023.

Tune In: The WWV Frequency Celebration will be held March 2 and 4, 2023, at the Fort Collins Museum of Discovery, and also on March 3 at WWV/B and the NIST Boulder labs.

Please read the announcement at the top of this page and also visit the event web pages as they become available. 

We hope to see you here in Fort Collins or have a QSO on the air soon.
