"You will need to connect the RF keying line from the amp to the radio."
That is not what I did when using a TS-590 with KPA500 and KAT500. I connected the TS-590 keying output to the KAT500 and then the KAT500 keying line to the KPA500. This routing of the keying line is required since the KAT500 must be able to interrupt amp keying when changing its configuration or when high reflected power is detected. My key line routing is actually a bit more complicated than that. My path is TS-590 > SteppIR interface > LP-100A > KAT500 > KPA500. They all have to agree it's ok to QRO before my KPA500 is keyed.
