Some of this is a place to start:
PTT-KEY OFF-OFF (Advanced) Allows selection of RTS or DTR lines (via the
USB or RS232
ports) to activate PTT or key the K3S. (See pg. 19 for connections.)
Example: if
the parameter is set to RTS-DTR, then the RTS line will activate PTT,
and DTR
will key the rig. Note: If a computer or other device asserts RTS or DTR
while
you’re in this menu entry, the K3S will switch to TEST mode (zero
output) as a
precaution. The TX icon will flash as a reminder. To avoid this, make sure
software has flow control and/or keying options turned OFF while you’re
changing the PTT-KEY selection.
TX LED on all the time: This could indicate that PTT is being held on by
external equipment. (Verify that
CONFIG:PTT-KEY is set to OFF-OFF if not keying via the USB or RS232
ports. Try disconnecting
equipment connected to the ACC, USB, and RS232 jacks.) Also check VOX
gain (unplug mic if necessary).
Unless you NEED the option, turn it off.... IF you need it, make sure
you setup flow control....

I've lost track of the (menu?) setting that prevents the K3 or K3S from
going into TX when the attached computer is powered on. The radio goes into
TX two or three times when the computer starts.
