You said you have sufficient audio, but please look at the ALC meter and
tell us whether or not you have 4 bars solid with the 5th flashing
during transmit. That is proof of sufficient audio.
Have you tried setting a different tone (say 915Hz) in both MMTTY and
the K3?

Bill, I've greatly simplified the setup for troubleshooting. All I have
running is MMTTY. The radio mode is for sure ASFK A.
If I simply change the mode to DATA A, all is well.
This seems to argue again a hardware issue, at least for the keying part of
the circuit.
