Frequency Measurement PRACTICE TONIGHT, March 29, 7pm MDST

We've held 3 FMP's or Frequency Measurement Practices this month, all a lot of fun and we think successful.

We're holding our last FMP TONIGHT, March 29, at 7pm MDST.  We hope you can tune in and also log into the Zoom session, info below:

The rest is from the original post of this page:

We plan to run a series of Frequency Measurement Practices, not exactly tests, but practice sessions for learning different techniques to measure frequency, and we hope more folks will give the April 2023 ARRL FMT a go after getting a little guidance from some pretty good FMTers that are part of the WWV Amateur Radio Club, N8OBJ and AD8Y.

We are planning to hold sessions on March 8, 15, 22, and 29 - all Wednesday evenings - with potentially various times on the different evenings.  We will have a Zoom meeting scheduled and will post that info 24 hours before each session. - <Sorry, this didn't always happen>

Participants are expected to have installed and successfully configured fldigi on a Mac or Windows PC including radio control and  good audio.  We will not spend time supporting fldigi installation or try to troubleshoot basic connectivity during our limited sessions. 

In addition, the session guides have worked hard to prepare, so please refrain from sharing your recommendations and taking us on a tangent until a later session where we will encourage group idea sharing.

Our first meeting is on Wednesday, March 8, at 7pm MST, 9pm EST, 8pm CST, and 6pm PST. 

John Gibbons, N8OBJ, has created a document for the FMPs:  How to Perform an FMT

As time permits to expand this section, of our website,  we'll explore the history of frequency measurement at WWV as well as how amateurs have pursued the science.  Frequency Measurement Tests (FMTs) are a long tradition, and with newer equipment and incredible software the science and art of frequency measurement have sparked a renewed interest among amateurs.

Additionally, the use of accurate software such as fldigi and WSJT-X has unlocked a bounty of citizen science initiatives.  We'll explore HamSci, plans for the upcoming 2024 Solar Eclipse, and the evolution of the Personal Space Weather Station as well as other hands-on programs.

Thanks for visiting and we will have regular updates <apparently we fell short here> here during March 2023 when we are running our FMPs.
