If Wayne will be tearing up the code in this area, it might not be hard
to fix the problem that the internal keyer weighting is much heavier in
PTT mode than in QSK or semi-QSK VOX.

May be Elecraft can also look at the 8 msec PTT delay which cannot be
made longer without distorting CW. Some of the apmplifiers are not that
quick.

Okay, lets take Eric's lead and open an interesting thread directly
related to an excellent Elecraft product.
For years many of us have suffered with the odd behavior of the K3
in CW PTT mode. There are at least two inexplicble aspects of K3
CW PTT behavior that have forced many of us to use external
Winkeyers rather than the poorly designed internal K3 keyer logic
when the K3 is in CW PTT mode.
For CW contesters, its necessary to operate the K3 in PTT mode
to avoid unwanted VOX delay. But for some strange reason the
K3 always applies VOX delay after external PTT is unasserted.
I can think of no logical reason why VOX delay should be applied
at the end of the external PTT input when the K3 is PTT mode or
any other mode. When PTT is unasserted, the K3 should always
immediately return to receive mode, no exceptions.
When using the internal K3 keyer when in PTT mode, for some
inexplicable reason the K3 behaves like its in QSK mode. The
only way to avoid this is to use VOX rather than PTT mode or
to use a foot switch when in PTT mode. Both alternatives
are unacceptable.
The band aid solution many contesters use with excellent results
is to avoid using the internal K3 keyer and to use an external
K1EL Winkeyer that generates both a key output and a PTT
signal generated according to well designed Winkeyer CW PTT
logic.
Why can't the K3 implement logic similar to the Winkeyer to
generate the equivalent of "Winkeyer PTT" when using the K3
internal keyer when the K3 is in PTT mode?
