The Amateur Radio on the International Space Station (ARISS) team is coordinating with Expedition 13 Commander Pavel Vinogradov, RV3BS, and ARISS-Russia's Sergei Samburov, RV3DR, to troubleshoot the slow-scan television (SSTV) system onboard the ISS. The SSTV system remains off the air for the time being.

"The ARISS team is coordinating with Sergei Samburov and Pavel Vinogradov to resolve some of the issues seen when the SSTV system was hooked up," ISS Ham Radio Project Engineer Kenneth Ransom, N5VHO, told ARRL. Photos of the current SSTV configuration that were downlinked to Earth showed "several unanticipated results" from the initial tests, Ransom said. "More extensive troubleshooting is being developed and could further delay permanent activation of the radio." He added that it could take a long time to work out the kinks because Vinogradov is only able to work on the system in his free time. Vinogradov will return to Earth in September.

Why we do not receive signals in each modes from the ISS?
Have they problems with the equipment or have they
forgotten to turn on the radio?
What is the reason?
