I'm not sure that (dropped FIGS) is what happened since it happened
for the same station (EE3R) each time, and David kept getting QR when
he asked for a repeat. Remember that David had mentioned

That is why I asked if the QR came right after a 599 and a SPACE.
The USOS/non-USOS mismatch is consistent with what happened, I believe.
It is because of this that I had added a "strong USOS" to cocoaModem
that makes the transmission compliant with both USOS receivers and non-
USOS receivers. The program can send a <SPACE><LTRS> pair for every
SPACE character in the buffer. There is the expense of an extra
LTRS, but it reduces requests for repeats. Pick your poison --
faster or more accurate :-).
