Upcoming ARISS radio contact between the International Space Station, call sign OR4ISS, and young people at the IARU Region 1 Camp, call sign FX5YOTA, on Tuesday, August 19, 2025, at 09:18:53 UTC (10:18 AM BST) on 145.800 MHz FM.

Astronaut Mike Fincke KE5AIT will operate the amateur radio station call sign OR4ISS aboard the ISS and will call the radio amateur ground station call sign FX5YOTA in France. This is a live ARISS radio contact from the Youngsters On The Air – Summer Camp in Jambville, France.

The YOTA Summer Camp is a chance of a lifetime for these young RSGB members to represent their country and their national society:
• Leon, 2E0VUF (UK Team Leader)
• Emily, M7HPU
• Sophie, M7IJG
• Sam, M0UEL
