On november 9, 2005 I received a part of a qso between the astronaut Steve McArthur flying in the International Space Station and some students in the United Kingdom.
The setup was very basic back then. A kenwood TM-G707 with a homemade J-antenna. The antenna was located next to my desk. Not the ideal setup, but I managed to get a clear copy of the ongoing conversation.
As a proof : download or listen to this mp3 file.
