December 26, 2023 — Amateur Radio on the International Space Station (ARISS) announces a special SSTV experiment to be held this week.  The ARISS Voice Repeater will be the downlink for enthusiasts, and several ARISS-selected ground stations around the world will serve as SSTV uplink stations.  Two special images will be transmitted on 437.800 MHz using PD120 formatting. 

This limited experiment will be conducted on several passes over Europe, Australia, and the USA between Wednesday, December 27 and Saturday, December 30, 2023.

ARISS hopes enthusiasts will have fun downloading the images and follow along with the event.

About ARISS:  

Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the American Radio Relay League (ARRL), Amateur Radio Digital Communications (ARDC), Radio Amateur Satellite Corporation (AMSAT), NASA’s Space Communications and Navigation program (SCaN), and the ISS National Lab—Space Station Explorers. The primary goal of ARISS is to promote exploration of science, technology, engineering, the arts, and mathematics topics. ARISS does this by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students. Before and during these radio contacts, students, educators, parents, and communities take part in hands-on learning activities tied to space, space technologies, and amateur radio.
