International Space Station FM Voice Repeater

The ARISS program is pleased to announce 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.

For further information on working satellites and adjusting for Doppler shift, please review Emily Clark's (W0EEC) excellent presentation on AMSAT's website.

ARISS is an international educational outreach program with US participation from NASA, AMSAT (The Amateur Satellite Radio Corp.), and the American Radio Relay League.

ARISS offers an opportunity for students to experience the excitement of Amateur Radio by talking directly with crew members on-board the International Space Station.

Teachers, parents and communities experience, first hand, how Amateur Radio and crew members on ISS can energize youngsters' interest in science, technology, and learning. Further information on the ARISS programme is available on the website http://www.rac.ca/ariss
