ARISS HamVideo Currently Not Transmitting


The HamVideo digital Amateur Television (DATV) transmitter aboard the International Space Station (ISS) Columbus module recently ceased transmitting. The unit's indicators show it is functioning but its signal cannot be detected on the ground. The ARISS team's efforts to get the transmitter working again have been unsuccessful, thus far.


A series of steps are currently being undertaken to try to diagnose the problem. However, if an actual failure occurred, only a ground-based evaluation will fully diagnose the problem. The ARISS International team is working diligently to bring HamVideo back to full operation as soon as practical. We have started coordination with our space agency partners and with our sponsors to expeditiously troubleshoot the issue on-board and, if necessary, troubleshoot and repair the device on the ground. 


The HamVideo DATV transmitter has become a very valuable educational asset that astronauts enjoy employing as part of the ARISS connection.  Astronauts Tim Peake, KG5BVI; Paolo Nespoli, IZ0JPA; and Thomas Pesquet, FX0ISS, regularly utilized HamTV to inspire students and educators during ARISS contacts scheduled as part of these astronauts' ISS missions. Australian and European HamTV ground stations have been operational for receiving and distributing DATV signals from the ISS, and in the US, HamTV stations are under development.  Several hams in Japan have set up ground stations that have received HamVideo.


As more information becomes available on the HamVideo status and on any potential repair plans, we will keep you informed through future news releases and via messages on the ARISS web site


ARISS relies on its sustaining sponsors, along with many devoted individual donors and ARISS volunteers, to support the day-to-day operations and to help with related expenses. These supporters are instrumental in developing and funding the build of our new radio systems. For everyone interested in helping ARISS inspire, engage and educate youth, hams and the public through amateur radio on the ISS, please donate to ARISS at or




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 Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in Space (CASIS) and the National Aeronautics and Space Administration (NASA).  The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues.  With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums.  Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies and amateur radio.  For more information, see,, and
