Carl,
Since you likely have a serial connection for rig control in addition to
the audio lines, you have an alternative to using the Fldigi 'tone keying'.
Tell the digital mode application to use either RTS or DTR for rig PTT --
Then set the K3 CONFIG: PTT-KEY menu to match the selection in your
software.
Only one downside to this method is when the computer boots, it will
test the DTR and RTS signal lines which will cause the K3 to go into
transmit temporarily (but with no audio, so no RF should be produced).
To prevent that from happening, boot the computer first and then power
the K3 on.

There's one good reason that I know of. The VOX on/off setting is shared by
AFSK, DATA A, and SSB. Having VOX left unintentionally active on SSB is
very bad -- it leads to amp faults and unintended transmissions
I've asked a few times for this to be fixed and swore to myself that I
would never mention it again but oops there I went...
73 and thanks for listening,
