  1. 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.

  2. 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.
