If the frequency is busy for a run, please standby and the FMT will start as soon as practical.
You don't have to use special lab equipment to enter the FMT. Modern HF transceivers can make frequency measurements quite accurately. SDR transceivers and PC software can make precise measurements of signal frequency.
If you've never entered an FMT before, information on how to measure the frequency of a carrier is available at www.k5cm.com, and in several previous QST articles listed below. Other practice FMTs are run throughout the year and are usually announced on the fmt-nuts group at groups.io/g/fmt-nuts.
Click on Data Entry in the navigation menu near the top of this page to submit your measurements. Results will be available immediately following the data entry deadline. Also, be sure to describe your setup when you submit your measurements online. The Green Box in the results shows stations submitting measurements with an accuracy of 1 Hz or better for all FMT frequencies.
