Save the dates! The next HamSCI workshop will be held virtually March 19-20, 2021. The HamSCI workshop is an annual meeting to share scientific and engineering ideas and results related to amateur radio, radio propagation, and radio science, as well as foster collaborations between the amateur radio and professional space science and space weather communities. The 2021 workshop will serve as both a team meeting for the Personal Space Weather Station project, as well as a forum for presentations on topics relevant to the HamSCI mission. The format will be similar to virtual March 2020 HamSCI workshop. Thanks to support from the National Science Foundation and The University of Scranton, the cost of this workshop is free. Abstract will be due February 15th. Information regarding abstract submission and other workshop details will be forthcoming. Please join the HamSCI Google Group to stay up-to-date on the latest information.
"The question was asked: why do we see sporadic-E like propagation in November and December, when many of the variables like UV radiation and solar exposure are at a minimum, unlike the very active sporadic-E summer months? Much like it was shown that North Atlantic transatlantic 6m propagation during the summer was made more possible by strategically placed weather storm systems, it looks like a similar effect with very strong jet stream boundaries also affect sporadic-e like communications during the winter months. This citizen science study is another example how amateur radio can contribute to science, and illustrates the great potentials for studies using ham radio data. We have many amateur radio stations on the air, using modes like FT8 which make contacts on propagation paths that we thought were previously impossible."
Ash Chaabane, 3V/KF5EYY, reports that a new Reverse Beacon Network (reversebeacon.net) node has been successfully installed in Tunisia. There will soon be an Algerian and Libyan node when logistics permit. The Tunisian node consists of a DX Engineering ARAV4-1P active vertical antenna (see the photo, contributed by Ash), a Red Pitaya 122-16 SDR, and CW Skimmer software by VE3NEA. You can see the stations reported on several bands by the new node at https://dxcluster.ha8tks.hu/azimuthal_map/index.php?c=3V/KF5EYY&t=de. This node was part of a Yasme Foundation (yasme.org) project to install more RBN nodes in out-of-the-way places not currently home to a receiver. The project aims to support both the amateur radio community and spaceweather/geophysics research community with propagation information from around the world and raise awareness of amateur radio's long-standing history of supporting science. Additional nodes are planned for the Caribbean, South Pacific, and Russia, while other groups are installing nodes in Australia.
Video recordings of the third annual HamSCI Workshop are now available through the Ham Radio 2.0 YouTube Channel. The 2020 HamSCI Workshop for amateur radio operators and professional scientists was held Friday and Saturday, March 20-21, 2020, virtually on Zoom at The University of Scranton. The theme of the workshop was “The Auroral Connection,” and included addresses by guest speakers, poster presentations, and demonstrations of relevant instrumentation and software.
HamSCI is seeking volunteers, especially in the Eastern Hemisphere, to help us collect data during the annular solar eclipse on June 21. There will be two data collection periods: A practice/control period on June 14 for participants to get their stations in order, and the main data collection period from June 20-22 UTC.
Much of HamSCI research looks at communications in the High Frequency (HF, 3-30 MHz) radio bands. The HF bands allow for both global communications and techniques for remote sensing the ionosphere and space. The HF bands have seen a resurgence in recent years, as new modulation techniques are developed and people realize the importance of diversifying their communications infrastructure. Paul Denisowski, KO4LZ, engineer for Rohde & Schwartz North America recently wrote a white paper entitled, "The Rebirth of HF".
