No.  I haven't used FSK for many moons now, Ian :-)

I haven't check closely before, but doesn't the K3 use Keyed AFSK  
instead of Direct FSK?

The AD9834 DDS that it uses is definitely capable of FSK and PSK, but  
both the FSELECT and PSELECT lines of the chip are grounded in the K3,  
so I have a sneaky suspicion that the rig might be a Keyed AFSK rig.
