When do you decide (when NOT in a contest) to log an "incomplete" FT8 QSO? For example, something like this:
CQ HIMHIM EM00 HIMHIM MEMEME FN00 MEMEME HIMHIM -07 HIMHIM MEMEME R-09 HIMHIM MEMEME R-09 HIMHIM MEMEME R-09
(and then both sides apparently walk away)
Now technically that's a 2-way contact because we both definitively copied an identifiable message from the other side.
But I have not been (initially) logging them because of the lack of a RRR or a RR73.
However, for some of these I see the QSO show up in eQSL. When it does I will confirm it if the signal report for himself in the eQSL entry matches the report I sent him in the QSO (figuring that he must have gotten it even if he never responded to it with RRR or RR73 or I didn't receive the RRR/RR73 he sent).
Once I do that I will upload the QSO to LOTW and upon doing so will often see a confirmation there as well.
So is this legit by both of us? On the one hand, the FT8 QSO didn't go to completion. On the other hand, we did both definitely copy each other at least once.
