Page 19 of 44 July 2018 | ST 19 radio station integrated onto Europa. It is a project of the Jupiter Research Amateur Radio Club (JRFARC), a group of amateur radio operators affiliated with JRF. HF Voyag- er is designed to allow two-way communications with amateur radio operators worldwide and supports a new communication mode that has taken the amateur radio world by storm: FT8. With shorter transmit-receive cy- cles making for quicker contacts, FT8 is the ideal mode for communicating with this remote station in the Pacif- ic Ocean. Ham operators call the Voyager on the 20-m amateur band, and (if propagation permits) the Voyager will respond with telemetry, including location and other data. The Voyager's responses occur from areas that are rarely occupied by human sailors. JRFARC has taken off-the-shelf components and cus- tomized and integrated them for this application. Addi- tionally, the system supports other digital-mode HF pro- tocols: PSK-31 for two-way communications, and WSPR (transmit only), which will allow them to create a prop- agation study based on the contacts received over the course of this transpacific mission.

Special thanks to Murray Taylor, Adam Taufmann, Kevin Rea and Ravi Mulam. ST Maya Goodoni recently obtained a B.A. in en- vironmental studies and will commence an en- vironmental science graduate program at the University of Hawaii at Hilo. She enjoys environ- mental and marine research and public outreach. Her goal is to help create more resilient socioeco- logical systems. Beth Goodwin, a U.S. Coast Guard-licensed cap- tain, has spent more than 30 years identifying ma- rine mammals throughout the eastern tropical Pa- cific. She is a co-founder of Liquid Robotics and has an M.A. in physiology and behavioral biology from San Francisco State University and a B.A. in marine biology from University of California, Santa Cruz. Kurt A.F. Kiesow III is a co-founder of both Jupiter Research Foundation (JRF) and Liquid Robotics. He has integrated numerous payloads and sen- sors in the maritime environment and currently manages several technical programs at JRF. Kie- sow is an active amateur radio operator and serves as the president of the JRF Amateur Radio Club.
