I believe you will find the (Straight) Key input will provide a carrier
in any mode if you turn on "CW in SSB" and enable VOX.  It has been
used that way with the Yaesu Quadra which requires a carrier for its
F-Set function.

Joe - The problem is that now you'll transmit at full power when you key the 
radio.  Not good for most external autotuners.  And probably not wonderful 
for the K3 output when playing into a relay-switched autotuner at full 
power.  I like the way so many other radios do it whereby the input from the 
external tuner puts the radio in a low-power TUNE mode.
