Hosted by Aaron Castillo

On this episode of Electronic Echoes we talk to Dr. Kim Andrew Elliott (KD9XB), former audience research analyst, for Voice of America and the Broadcasting Board of Governors, former producer of “Communications World,” and “VOA Radiogram” for the Voice of America, and current producer of Shortwave Radiogram (SWRadiogram), a weekly broadcast that transmits interesting articles, and images over the air via Shortwave Radio. Come along as we talk about what a Radiogram is exactly, the evolution of text and images over the air, and how SDRadiogram is run. Learn about what it takes to run a show on Shortwave, and some of the experiments, challenges, and successes that come along each week.

Electronic Echoes: Studying our Ocean in the Sky

Hosted by Aaron Castillo

In this episode of Electronic Echoes, we talk to Kristina Collins of HamSCI, about the science behind Shortwave Radio, and how citizen scientists expand our understanding every day. Kristina is a Ph.D. student at Case Western Reserve University and a member of both the Case Western Ham Club and HamSCI. She has authored various scientific papers for HamSCI, and is involved in and chaired various HamSCI projects. Come along as we talk about vast and relatively unexplored Ionosphere, its role in Shortwave Radio propagation, what factors affect it, and how HamSCI is setting up experiments, and eventually hardware that allows anybody to make their very own “Space Weather Station,” that can help us understand this vast “Ocean in the sky.” You can learn more about HamSCI at www.hamsci.org, and the Case Western Radio Club (W8EDU) at w8edu.wordpress.com.
