ISS Fan Club

The only thing you may be doing wrong is trying modes that are not active. There is currently one active radio on the ISS and it has been mainly in the packet mode or off. Trying any other modes when one is active is no use.

Trying to contact the crew is like working rare DX stations. You can only do it when someone is at the radio.

My advice is to monitor the activity reports to get an idea of what mode is active. To work the crew, be available for every pass as you never know when a crew member will pick up the microphone.
