Most Amateur Radio on the International Space Station (ARISS) operations are split-frequency (each station uses separate receive and transmit frequencies). The downlink is the earth station’s receiving frequency. The uplink is the earth station’s transmitting frequency.

In ITU Region 1 should you be fortunate enough to hear an astronaut calling CQ on the 145.800 MHz downlink you should switch in your -600 kHz repeater shift so your reply is on the 145.200 MHz uplink.

You can follow the path of the space station on the ISS Dashboard

The contact will be web streamed from the school, watch live at
