I have had this problem for a long time with the
KX3 and ultimately figured out that the solution
is exactly what Dan had stated. When using the
SignalLink USB only use VOX (on the KX3), or on
the K3 use the back panel PTT and do not use the
CAT for PTT. Without this the combination
consistently creates exactly the race condition
that puts the K3/KX3 in an indeterminate state
requiring the XMIT panel button to clear. I
think the problem is that the delay in the
SignalLink release of the PTT line. That is the
CAT control tries to open PTT while the
SignalLink USB is still grounding PTT so the
radio does not know what state it is in.
I use this system and it works fine as long as I
do not try CAT control for PTT.
Thanks,

Interestingly enough I have something like that happen now and then as
well...
I am driving the K3 directly with a serial port from my computer, and in
DATA A mode, so far only when in DATA A. I operate 90% in DATA A so
take that last one with a grain of salt... Although it has never
happened in CW mode.
Once the problem has been triggered, if I tap the XMIT button and it
drops out of transmit. Next time, I'll try a different button...
I am using no interface...
