[Elecraft] K3 ALC Behavior When Using WSJT-X

I recently had to install a soundcard dongle when my internal card went
TU.  When operating WSJT-X, I notice that the ALC runs the 4-bar
solid/5th-bar flicker normal operation during the transmit cycle.  At the
end of the cycle it jumps to 6 or 7 bars before the receive cycle starts.
 This does not seem to affect the K3 when running barefoot; however, when
using the KPA500, the output spikes almost to 700W at times before the
switchover.

Any suggestions where to point the finger?
