The internal tuner does not change the SWR on the feedline (at the
output of the tuner). It will change the SWR that is at the input of
the tuner, and that is the SWR indicated by the K3. The W2 is
indicating the SWR at the tuner output (and that will not change with
tuning).
For those who want to have the feedline SWR and the power output
displayed, the W2 is "the way to go", if that does not interest you,
then it may not be of value to you.

On a particular band I use the K3’s internal antenna tuner to tune the SWR to
1.0-1 or so it says. I have a W2 attached inline and it reads an SWR of 1.7-1+
for the same setting. Which is correct? can the W2 readings be
adjusted/reconciled with the readings on the K3? is there a problem? What is
the point of the W2 if its it does not reflect ( no pun intended) the correct
readings?
