[Elecraft] KX3 CAT control fails via KXPA100

[Jim Kutsch, KY2D]

My KXPA100 arrived yesterday. It's a great amp and very easy to setup and
use. I have one unexpected issue though.

 

Set up is PC connected via KUSB to the KXPA100, KXPA100 connected by KXPACBL
to the KX3, and latest firmware on both. When PA Mode is set to on, Amateur
Contact log cannot read or set anything (e.g., frequency or mode) on the
KX3. When PA Mode is set to off, all works as expected.

 

Is this a known issue or might I have something configured incorrectly?

 

Thanks and 73, Jim
