The ISS system has sometimes been turned on to Cross Band Repeat mode. In this mode it functions as a Mode B-FM repeater. Amateurs in the US and elsewhere have reported using the repeater with home stations and handheld radios with great success. The crew is also able to use the radio to transmit even when the system is in this mode.

While the system is in cross band repeat mode the packet system is turned off and vice-versa.

The ISS daily crew schedule can be found at Remember that the crew operates on UTC time. Also, all of the time line is NOT translated from Russian and posted.
