The amateur radio community is a global, highly engaged, and technical community with an intense interest in space weather, its underlying physics, and how it impacts radio communications. The large-scale observational capabilities of distributed instrumentation fielded by amateur radio operators and radio science enthusiasts offers a tremendous opportunity to advance the fields of heliophysics, radio science, and space weather. Well-established amateur radio networks like the RBN, WSPRNet, and PSKReporter already provide rich, ever-growing, long-term data of bottomside ionospheric observations. Up-and-coming purpose-built citizen science networks, and their associated novel instruments, offer opportunities for citizen scientists, professional researchers, and industry to field networks for specific science questions and operational needs. Here, we discuss the scientific and technical capabilities of the global amateur radio community, review methods of collaboration between the amateur radio and professional scientific community, and review recent peer-reviewed studies that have made use of amateur radio data and methods. Finally, we present recommendations submitted to the U.S. National Academy of Science Decadal Survey for Solar and Space Physics (Heliophysics) 2024–2033 for using amateur radio to further advance heliophysics and for fostering deeper collaborations between the professional science and amateur radio communities. Technical recommendations include increasing support for distributed instrumentation fielded by amateur radio operators and citizen scientists, developing novel transmissions of RF signals that can be used in citizen science experiments, developing new amateur radio modes that simultaneously allow for communications and ionospheric sounding, and formally incorporating the amateur radio community and its observational assets into the Space Weather R2O2R framework. Collaborative recommendations include allocating resources for amateur radio citizen science research projects and activities, developing amateur radio research and educational activities in collaboration with leading organizations within the amateur radio community, facilitating communication and collegiality between professional researchers and amateurs, ensuring that proposed projects are of a mutual benefit to both the professional research and amateur radio communities, and working towards diverse, equitable, and inclusive communities.

Measurement of Doppler shifts of high frequency (HF) radio signals emitted by precision frequency transmitters is a well-established technique for the detection of traveling ionospheric disturbances and other perturbations in the bottomside ionosphere. Because Doppler measurements require minimal instrumentation, this technique naturally lends itself to crowdsourced data collection, and purpose-built instrumentation platforms are desirable in order to maximize consistency and repeatability. However, even the best system only has value if it is used, and a robust and engaged community of citizen scientists is vital to sustaining instrumentation platforms. The Ham Radio Science Citizen Investigation (HamSCI) has developed a prototype, low-cost system for making HF Doppler shift measurements of signals from standards stations such as WWV (Fort Collins, Colorado, USA) and CHU (Ottawa, Ontario, Canada). This system, known as the Personal Space Weather Station Grape Version 1, consists of a low intermediate frequency (IF) mixer board, GPS disciplined oscillator, and Raspberry Pi. In collaboration with funded project scientists and engineers, volunteer HamSCI community members developed instructions for building and operating a Grape Version 1 on the HamSCI website. In this presentation, we explain the process for constructing a Grape Version 1 and discuss the experiences of volunteers who have built and are now operating this system. We also discuss preliminary data from these stations, which show dramatic Doppler shifts during sunrise and sunset and during solar events. Concurrent data from multiple proximal stations show shared features and can be used for validation. These stations constitute the first iteration of the Personal Space Weather Station network.

Traveling Ionospheric Disturbances (TIDs) are quasi-periodic variations in ionospheric electron density that are often associated with atmospheric gravity waves. TIDs cause amplitude and frequency variations in high frequency (HF, 3-30 MHz) refracted radio waves. We present observations of TIDs made with a network of Ham Radio Science Citizen Investigation (HamSCI) Low-Cost Personal Space Weather Stations (PSWS) with nodes located in Pennsylvania, New Jersey, and Ohio. The TIDs were detected in the Doppler shifted carrier of the received signal from the WWV frequency and time standard station near Fort Collins, CO. Using a lagged cross correlation analysis, we demonstrate a method for determining TID wavelength, direction, and period using the collected WWV HF Doppler shifted data.
