A DATV (digital amateur television) transmitter was installed in the Columbus module of the International Space Station (ISS). This transmitter is dubbed “Ham Video”.
By now, no HAMTV Video Contacts are currently scheduled, due to malfunction of the HamTV Transmitter on the ISS.
Ham Video was tested and needed to be returned Earth to be checked; so was returned Earth in January 2019 and now is waiting for inspection and possible repair.
