John, your understanding is correct unless the K3 ATU is in bypass mode
which it was for my tests. The K3 then should be measuring the feed line SWR
because there is no tuner in the circuit. Also I used tune mode which shows
the digital readout of SWR, not the number of bars on the SWR readout. So
try it with the K3 tuner bypassed and see what you get.
