Ah, OK - I got ahead of myself.  I thought we were discussing
hot-switching linear amplifiers and the need to PTT control them to
avoid losing the beginning of a CW transmission.

If I am running semi- or non-QSK I always just adjust the QSK delay and
amp hang time so that it doesn't quite drop out during CQ's and then
instantly releases after the end of my CQ.  I haven't ever experienced
the "missing dit" on incoming callsigns when I am CQing.  I just adjust
QSK delay and/or amp hang time so the transmission ends at the end of
my CQ and then I respond to the caller.  Other times, I run total full
break-in and this is even more of a non-issue.
