I'm pretty certain that KX3 does not have such a port. Ten Tec's 
original method of QSK where you key the amp and the amp keys the radio 
is not the only way to run QSK with a Ten Tec amp -- IF the rig delays 
TX for a few msec after asserting the PTT for the amp. I can run full 
QSK by setting my Titans  and Herc II for PTT mode needed with rigs like 
the K3 and FT1000MP that are designed this way.  I suspect that the KX3 
is too.  That should be easy to check -- the manual can be downloaded 
from the website. Look for a menu setting for TX Delay.  The default 
setting for the K3 is 8msec, but it can be changed in 1 msec steps.
