A report from 9W2QC from Malaysia indicates the crossband repeater on ISS is currently active. It should stay operational until the unit must be shut down for the undocking operations of the Progress 27 on Feb 4. Frequencies are 437.800 MHz uplink and 145.800 MHz downlink. Keep in mind the extreme Doppler on the uplink and it is highly recommended that you operate full duplex to see if you are making it through or interfering with another station unknowingly.

Enjoy and good luck.
