Friends, Having hosted an ARISS contact myself earlier this year, I am well aware of direct contacts between the astronauts and someone on the ground.
The relevant part of the question was the part about the QSO being *THROUGH an AMATEUR RADIO SATELLITE TRANSPONDER*.
If you are aware of a success (or a failed attempt) I would be interested in knowing which astronaut and which amateur radio satellite was used.
Lastly, does anyone have a technical references for correcting calculating the Doppler for a QSO from ISS through a satellite to the ground? (And no, you can't just change the tracking program's ground station latitude/longitude every second to match the ISS satellite subpoint.)
Thanks and 73, Douglas KA2UPW/5
