	abstract = {<p>The NASA-run citizen science project, Radio JOVE, utilizes widespread distribution of single and dual-dipole antenna receiving stations to study the magnetic interactions between Jupiter and its moon, Io. The citizen science effort has been well established and maintained since 1998, and the Radio JOVE project team has streamlined kit distribution and assembly documentation for amateur data collectors and hobbyists. The antennas, receiver, software, and related components are available for purchase in kits that range in price from depending on the level of {\textquotedblleft}pre-assembly{\textquotedblright}. For instance, we estimate that the prices of un-assembled and fully assembled kit receivers are approximately $95 and $225, respectively. Establishing a Radio JOVE receiving station is no small task, and these prices are reasonable and appropriate. To further data collection accessibility and broaden the participating audience, however, we seek to further reduce these costs-- specifically that of the receiver. Our primary goal is to code, integrate, and test a software-defined radio (SDR) receiver for Radio JOVE data collection to verify whether the technology could be a less expensive alternative to the original distributed kit receiver. By coordinating with the Case Western Reserve University (CWRU) Research Farm, as well as with guidance from faculty in the CWRU Electrical, Computer, and Science Engineering (ECSE) department and the Radio JOVE Project Team, we hope to establish a Radio JOVE receiving station at CWRU whereupon we can test our alternative SDR receiver for Jovian signal collection. If our alternative receiver works on a level comparable to the existing kit receiver, we can offer a cheaper, more modern and digital age approach that could appeal to a wider audience including those working with a tighter budget and those who are interested in software-defined radio, all of whom simply want to help the scientific effort.\&nbsp;</p>

	abstract = {<p>Advancement in understanding short term and small spatial scale ionospheric variability requires global high time and spatial resolution measurements. Professional ionospheric sounding networks are extensive and capable, yet more measurements are still needed due to the strongly magnetized nature and large extent of the ionosphere. High Frequency (HF, 3-30 MHz) radio signals are refracted by the ionosphere, and therefore are modulated by processes such as traveling ionospheric disturbances (TIDs) and geomagnetic storms. By measuring the amplitude and Doppler shift of trans-ionospheric HF signals, it is possible to detect signatures of ionospheric absorption and changes in propagation path length. We present a design for a low-cost citizen science HF multi-band receiver that measures the amplitude and Doppler shift of reference signals of opportunity from the US National Institute of Standards and Technology station WWV and the Canadian Institute for National Measurement Standards station CHU. The receiver will make 1 s cadence measurements on nine HF beacon frequencies and subsequently upload the results to a central server for scientific analysis. The local user will be able to review data daily, both locally and in aggregate on a web server, and participate in discussion of the ionospheric measurements. This receiver forms one component of the low-cost version of the Ham Radio Science Citizen Investigation (HamSCI) Personal Space Weather Station (PSWS), and is designed with the intention of distribution to hundreds to thousands of citizen science observers. Preliminary results from the prototype receiver will be presented.</p>
