I know this will seem incredible to the software purists, but I have an
actual mechanical "switch" in series with the PTT line. The K3 is always
in QSK mode, but if I get tired of all the racket, I can just turn on
the PTT. That seems to work flawlessly with the KPA1500, as well as my
old tube amplifiers. (There's another switch in the keying line, just in
case the computer goes nuts. Of course, that could NEVER happen.)

This appears to be, at least in part, a simple matter of RTFM. Also,
my manual is 9 years old, and there's obviously been a lot of stuff
added since then. Experimentally, it appears that must have *both* QSK
on - whether Full or Semi - and VOX on. Once I do this, I see my
first dots on the KPA-1500 bar-graph every time. I do not want to use
the built-in keyer in the K3, because most of my operating is CW
contesting, and I want to use the Winkeyer to send stored messages
from N1MM +. The manual makes it clear (if only I'd read it) that
both QSK and VOX must be enabled for CW. In PTT mode, it appears that
my keyer is sending the PTT signal simultaneously with the first RF -
not good.
Thanks to everyone who helped put me on the right track.

See CW QRO and TX DELAY in the menu. Also the benefits and likely
issues are described in the manual, page 58 and 66 as MENU items.
As to using other means to key the radio and amp and send CW, those
may have their own settings as required.
While I do not consider myself a high speed CW op, I do work QSK. I
do not find any truncation of the first CW element. I use the
internal keyer and either a Vibroplex Iambic paddle or a Vibroplex
single level paddle. I have VOX set to ON, CW QRO is OFF and TX DLY
to NOR and 008.
Hope this helps.

"It occurs if the rising edge of the keying waveform happens at the

keying waveform slightly so it occurs after the PTT."
That would seem to imply that you are not using CW VOX keying. If
that is the case then wouldn't using CW VOX eliminate the issue?
