    Interesting. If you can bounce a signal off of the moon, aurora, or a meteor shower-why not a space station? I’m surprised that they tried using BPSK63 versus the more robust WSJT.

    Having watched the ISS zip across the sky and having worked the packet station aboard it, I can relate to the author’s complaints about Doppler. Must have been quite a challenge! Very impressive.
