ARLS007 Space Station Digital Amateur Radio TV System Transmitter
Determined to be Defective

The Amateur Radio on the International Space Station (ARISS) "Ham
Video" digital Amateur Radio TV (DATV) transmitter on the
International Space Station (ISS) is reported to be defective, with
onboard repair not possible. Also known as HamTV, the DATV system
stopped working in mid-April, and a subsequent test on June 1 using
a second L/S band patch antenna on the Columbus module had failed.
ARISS-EU Mentor Gaston Bertels, ON4WF, said ARISS plans to return
the transmitter to Earth to repair, pending space agency approvals
and availability of ARISS funds.

"Schools and crew members performing educational ARISS school
contacts are delighted to use Ham Video," Bertels said. "We will do
the best we can to restart this service as soon as possible."

Following extensive testing, the Ham TV system was first used for an
ARISS school contact in February 2016.
