This dataset contains observations of WWV 10 MHz gathered from December 1 through 10, 2021 as part of the study of the effects of solar eclipses on the ionosphere. The data was collected by amateur radio station K1FR located at 38.828, -77.104 using a FlexRadio 6700 with GPSDO connected to a long wire antenna. The Audacity application was used to record the realtime audio of the receiver which was in the USB mode and tuned to 9999.000 kHz thus producing a 1000 hz tone at the carrier frequency of WWV. The AGC on the receiver was set to “ON-medium.” PLEASE NOTE: due to operator error, the metadata in the Audacity generated .WAV files show that the AGC was “OFF”. See DOI 10.5281/zenodo.5775043 for data taken via the fldigi application on the same audio stream simultaneously. That dataset has .CSV files of the apparent doppler of WWV 10 MHz, and these files are named “analysis_xxxxx_K1FR-1.CSV.
