INTERNATIONAL SPACE STATION NOW IN REPEATER MODE

The ARISS programme announced that  the amateur radio equipment aboard the International Space Station is now operating in cross-band repeat mode.  We realize that many of you will miss the packet-operating mode.  However, cross-band repeat allows further experimentation of the ISS amateur radio system.

The downlink for this operating mode remains the same, so listen for the station on 145.80 MHz.  The new uplink frequency is 437.80 MHz.  All frequencies are subject to Doppler shifting.
