Frequency and amplitude estimation data collected by Grape V1 stations in the Personal Space Weather Station network. 

We gratefully acknowledge the support of NSF Grants AGS-2002278, AGS-1932997, and AGS-1932972. This work was undertaken through the HamSCI community ( We thank our volunteers for giving generously of their time and expertise. We also thank the maintainers of the first contingent of Grape stations for pioneering the PSWS network. Hardware was constructed in the Sears Undergraduate Design Laboratory and think[box] at CWRU. Finally, we thank the staff of WWV, WWVH and CHU, without whom this work would not be possible.
