Step by step
Listening to the ISS
- ARISSThe ISS has a ham radio on board. The project is called ARISS (Amateur Radio on the International Space Station).
- School contactsAstronauts talk to school students over the radio. These contacts are scheduled in advance.
- FrequencyThe voice is on 145.800 MHz, FM.
- HandheldA handheld and a small antenna are enough to listen. You need a licence to transmit.
- The passYou can hear the station only while it passes over you, and that lasts a few minutes.
- DopplerThe station moves fast, so the frequency shifts slightly during a pass. This is called the Doppler shift.
