I the VOX turned off and have my computer or foot switch key my SEQUENCER, which 
in turn finally keys up the K3 via the microphone PTT.  In that way, the K3 can 
never be switched HOT (unless it is put into XMIT mode automatically during 
firmware updates or something direct such as that).  GL and VY 73, Lance
