CAN HAMS MAKE AN UNSCHEDULED ARISS CONTACT?
Yes. The ISS crew has not lost sight of why ARISS has been so successful. It is the Amateur Radio community that has brought astronauts voices into schools. Crew members make random contacts with earth-bound hams. They make contacts during their breaks, pre-sleep time and before and after meal-time. Astronauts have contacted thousands of hams around the world. Computer software allows the crew to operate the 2-meter packet gear radio in unattended mode, and hams can make contacts when the crewmembers are working.
