The first session took place when the ISS came above the horizon at 18:37 GMT (7:37 pm BST) on Tuesday, August 8. The HamTV Digital Amateur Television pictures on 2395 MHz were successfully received and participants were able to see Paolo Nespoli IZ0JPA floating in the Columbus module of the ISS. Paolo, operating with the call sign NA1SS, was able to receive the transmission from the YOTA station GB4YOTA but there seemed to be an issue with the 145.800 MHz Ericsson transceiver on the ISS and Paolo’s voice transmissions could not be heard.
The second session took place during the next orbital pass at 20:15 GMT (9:15 pm BST). For this session Paolo operated the amateur radio station (Kenwood TM-D710 transceiver) located in the Russian Service Module.
The transmission was heard loud and clear at Gilwell Park and the young radio amateurs were able to ask Paolo their questions.
