June 2021 Eclipse Festival of Frequency Measurement

There will be an optional practice session on May 30th to select one or more beacon stations for the experiment. To participate, please listen for RWM (4.996 MHz, 9.996 MHz) and WWV (5 MHz, 10 MHz) on your radio and fill out the survey below. It's best to record around the same time of day as the eclipse (8 am UTC). If possible, please make a short recording with Audacity and upload it here. 

The primary beacon for this experiment will be the Russian time standard station RWM on 9.996 MHz . If you are unable to receive it at your station, please try 10 MHz WWV or another station from this list. Experiment with your radio to see which stations are easiest for you to receive. 

2) Collect data according to the instructions on this page: hamsci.org/doppler-instructions Use the instructions on collecting audio data in Audacity, not fldigi.  If you collected data for the December 2020 Eclipse Festival, the procedure is very similar, except that the local oscillator frequency must be included in the filename.
