via the ARRL: Space Station Digital Amateur Television Signal Not Being Seen on the Ground

The signal from the digital amateur television (DATV) transmitter aboard the International Space Station (ISS) cannot be detected on the ground, Amateur Radio on the International Space Station (ARISS) has reported. The unit indicates that it is functioning, however. So far, ARISS has been at a loss to pin down the problem.

“A series of steps are currently being undertaken to try to diagnose the problem,” a May 10 announcement from ARISS said. “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 [the system] back to full operation as soon as practical.” The ISS DATV system is known variously as “HamVideo” and “HamTV.”

ARISS said it has begun coordination with its space agency partners and sponsors to “expeditiously troubleshoot the issue onboard and, if necessary, troubleshoot and repair the device on the ground.”
