The International Space Station (NASA)

On 9 December 2007 Frank DH7FB and I completed the first ever QSO on 144 MHz using the International Space Station ISS as reflector - and many more since then.
Here you can download two MP3 files with combined signal recordings from DH7FB/P in JO63SC and DF2ZC. Equipment used at both sides were about 750 watts at the splitters and a 20 dBd yagi group at DH7FB/P and a 21 dBd yagi group at DF2ZC.
