[Elecraft] KXPA100 Utility v1.14.11 CONFUSION and HELP!

[Esquer Dave]

New KXPA100 (with 100w internal ATU) for KX3 owner. I have the KX3 and KXPA100 hooked up with the Elecraft supplied cables.

In the Amplifier section of the utility, when using the KXPA utility, why is the PA Bypass box checked? I understand the Attenuator box being unchecked.

In the Anntenna Tuner section, the Tune button (on the right) does not tune the rig, it just causes the 25w LED to blink. No noise is heard from the ATU. I have to physically hit the ATU tune button on the KX3 to retune.

Finally, in the same Antenna Tuner section, why is the ATU Bypassed check box (below the Mode options) checked when the Mode box is set to Auto?

I’m doing something wrong, please help this newbie.
