Understood, Bob.  

My point was that in the radio, with the VOX correctly adjusted, response to a 
transmit command using VOX is virtually indistinguishable from PTT.  Any 
significant delay is on the release. Agree with you that PTT is the better 
choice.  Only mention VOX because that is what was chosen in the setup in this 
case.

Btw, I copied your setup parameters for my K3 in the WSJT-X setup and I still 
get the same, consistent 1-second delay before audio is transmitted.  This is 
not a problem, for me anyway.  But those who are seeing longer, varying length 
delays, it's puzzling.  Computer OS problems, possibly?

But there is a delay in WSJT-X.   See the F2 Setup,  Advanced tab and 
Miscellaneous.   Make sure the TX Delay is set to 0.1 sec. This is the time 
delay between PTT and start of audio.  Also, if one uses CAT control, then be 
sure the VOX on the radio is OFF. Don't use both.
