Skip,
Yes, it does follow the keying when in QSK. If it did not, the KPA500
would not follow the K3(s) in QSK mode (the KPA500 connection uses the
KEYOUT-LP from the ACC connector).
The T/R switching is all electronic and can be quite fast.
If the amplifier uses relay switching, the relay may not be able to
follow the K3(S).

Related question: Does KEY OUT essentially follow the TX state? IAW,
if PTT or VOX is asserted, it also asserts? If so, I guess that means
that it follows the keying when in QSK? It's a real PITA to get to the
back of my K3 right now or I'd check it myself.
