WW0WWV will be on the air

May 20 celebrating World Metrology Day.

Check out our operating schedule on our website:  wwvarc.org

World Metrology Day is the annual celebration of the signature of the Metre Convention on 20 May 1875 by representatives of seventeen nations. The Convention set the framework for global collaboration in the science of measurement and in its industrial, commercial and societal applications. The original aim of the Metre Convention - the world-wide uniformity of measurement - remains as important today as it was in 1875.

We've just launched a new operating event for the WWV Amateur Radio Club called

1stOnAir

Starting on February 1st and continuing every 1st of the month, WWV ARC members are encouraged to get on the air for our 1stOnAir operating event.  We'll schedule a 24-hour period aligned with a standard UTC day.  The format is exactly like our October Anniversary operating event.  Operators who would like to take part should contact Dave Swartz at swartzdaveco@gmail.com or R.J. Bragg at airrj1@gmail.com to request access to the Google event folder for the schedule (below) and also Operating Guidelines.

Our next event is May 20, 2026 !   This is World Metrology Day

Our next 1stOnAir is June 1, 2026 !   Check below to see who is operating when.

For club operators, please place your call sign in the appropriate cell for the hour, band, and mode of operation.  Visitors to this website are able to scroll the operating schedule and see who is where and when.  If you decide to change when you're operating, please be sure to make changes at the Google site.  Consider signing for a 1 hour window at first to allow others on a busy band, but if an hour is vacant on the schedule, feel free to take a slot if it appears open. Sign in!

If you're operating digital or CW your exchanges are usually limited to signal reports, maybe a short CW conversation.  On sideband you have the chance to share more and learn of each other's WWV stories.  Be sure to share yours!  Read the Operators Guide and also follow some of the links to the history of the station if you care to have more knowledge of WWV in general.

Thank you for the great February , March,  April, and May 1st events so far!  June 1 will be on a Sunday evening and Monday in the States...

The Enhanced WWVB Broadcast

The next meeting for the WWV Amateur Radio Club is on Thursday, May 28, 2026, at 6pm MDST via Zoom.

The May 28 meeting will feature Dr. Oren Eliezer.  His talk reviews the history and technical details of the enhanced WWVB broadcast, which was introduced by NIST in 2012 to allow for more reliable reception of the station’s broadcast throughout North America. It will include the background for the enhancement, the communication theory behind it, the speaker’s personal experiences leading the engineering effort and interacting with NIST, the architecture of the receiver IC for the enhanced broadcast, photos from the station, and some entertaining stories.

The Zoom meeting will open at 5:30pm MDST for shooting the breeze for about 30 minutes until our meeting STARTS OFFICIALLY AT 6PM MDST.

Please log in to see the meeting information details. Use the menu item "Our Club" and then "Meeting Information" for club agendas and the Zoom info.

The WWV ARC was created in January 2019 to celebrate the 100th Anniversary of NIST Radio Station WWV, located near Fort Collins, Colorado since 1966.  After the very successful October 2019 100th 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.

Our mission statement:

The WWV Amateur Radio Club (WWVARC) exclusively promotes and celebrates the historic, scientific, and cultural importance of radio station WWV and amateur radio by conducting club educational programs and activities related to WWV, time and frequency measurement, and amateur radio.

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 of the US Government.

WWVB South Antenna Repairs

On April 6, 2024, and incredible wind storm hit the entire Front Range of Colorado, all the way south from New Mexico to Wyoming.  I-25 near WWV was shutdown in both directions due to blowing dust, and wind speeds were clocked in the 90 mph range nearby.  The WWVB South top-hat and antenna collapsed when one of the crimps on the center-span cable, the triatic cable, failed at the top of tower #4.  Read the details in our story "WWVB South Antenna damaged by severe winds" under the NIST News tab on our main menu.

WSPRsonde-8 now transmitting as WW0WWV from the WWVB site on 7 amateur bands

The newest addition to the WWV/H Modulation Working Group partnership between NIST and HamSCI is a WSPRsonde-8, an 8 channel WSPR transmitter manufactured by Turn Island Systems.  The transmitter went on the air in mid July 2024 and recently added a 12m broadcast.  Read the details in our story "WSPRsonde-8 now transmitting from WWV/WWVB" soon to be posted under the NIST News menu tab.

As you can see, our club has several projects underway and we'd love to have you involved in our club!

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