I made up a cable to go from my FT-2000 Band Data port to the Aux port of the KPA500. It works perfectly; changes bands on the KPA when I change them on the Yaesu and keys the amp too without the need for a line to the PA KEY port on the amp.
While set up this way, the band buttons on the KPA are inop. I am assuming this is by design to prevent transmitting on the wrong band, but I just want to make sure I didn't do something wrong.
