Hi Ted!

It sounds like you didn't have a complete QSO.  From what you wrote, it
looks like what shows up in red was transmitted from the ISS digipeater.
If you are seeing the packets as they are going from your station and from
the ISS, you should see something that includes "Via RS0ISS*" -
indicating a packet that was retransmitted by the ISS digipeater.  Do you
see a screen that looks something like the screenshot at:


(thanks to Mike AI6GS for posting that screenshot on his Twitter feed)

At a minimum, whatever you transmit needs to be digipeated by the ISS.
Then the other station needs to receive what is retransmitted, plus you
need to get something from the other station digipeated by the ISS.  There
needs to be some sort of back-and-forth, just like we do when working
other satellites in a voice mode or CW.

As for your other question, yes - you can log ISS packet contacts in the
Logbook of the World.  You'd set the PROP_MODE field in your QSO records
to be SAT, and use ARISS as the SAT_NAME.

If you'd like to try to make a QSO with me, let's chat away from this list and
see about making that happen.  I've made a few packet QSOs through the
ISS digipeater in the past couple of months, and would be happy to give it
a try with you.  Or, on the weekends in the afternoons, we could also try
