Ham Radio Science Citizen Investigation

Advance scientific research and understanding through amateur radio activities.
Encourage the development of new technologies to support this research.
Provide educational opportunities for the amateur community and the general public.

The first science results from the 21 August 2017 Solar Eclipse QSO Party have been published in the American Geophysical Union journal Geophysical Research LettersIn the paper, "Modeling Amateur Radio Soundings of the Ionospheric Response to the 2017 Great American Eclipse," Nathaniel Frissell, W2NAF, and team present Reverse Beacon Network (RBN) observations of the SEQP and compare them with raytracings through an eclipsed version of the physics-based ionospheric model SAMI3. On  14 MHz (20 m), eclipse effects were observed as a drop-off in communications for an hour before and after eclipse maximum. On 7 MHz (40 m), typical path lengths extended from about 500 km to 1000 km for 45 minutes before and after eclipse maximum. On 1.8 MHz (160 m) and 3.5 MHz (80 m), eclipse effects were observed as band openings 20 to 45 minutes around eclipse maximum.

UPDATE: Booth talk scheduled update 8 May 2018.

HamSCI will again be at the Dayton Hamvention, this year as part of the new Ham Radio 2.0: Innovation and Discovery area sponsored by the Yasme Foundation. Come visit the HamSCI Booth and Forum to learn about projects on the cutting of ham radio science and engineering research, including initial science results of the Solar Eclipse QSO Party (SEQP), the status of the Arecibo Observatory, the latest in understanding the causes of 6 meter sporadic E propagation, and how an inexpensive software defined radar for ionospheric studies works. Hamvention will be held May 18-20, 2018 at the Greene County Fairgrounds in Xenia, Ohio.

Microwave Update (MUD) is an international conference dedicated to microwave equipment design, construction, and operation. It is focused on, but not limited to, amateur radio on the microwave bands. The Midwest VHF/UHF Society is pleased to host this year's event. The conference will be held at the Holiday Inn, 2800 Presidential Drive, Fairborn, Ohio 45324 from October 11 - 14, 2018.
