Sigh.... Please excuse my frustration.

My original posting was clear: MMTTY _is_ putting the K3s into transmit 
and _is_ sending tones to the built-in sound card. I can hear the tones 
when the K3s is in XMIT, but no RF comes out the antenna connector.

The red TX LED on the K3s turns on, and the RF bar graph displays one 
bar, or zero watts. I can hear the tones in the K3s speaker and phones 
plugged into the rear panel.

There is no need for VOX -- MMTTY puts the K3s into XMIT if PTT is 
turned on _and/or_ if VOX is turned on.

Everything is fine except the K3s is not transmitting the audio from the 
built-in sound card.

I'll keep trying.
