[Elecraft] KAT500 and KPA500 integration

[ANDY DURBIN]

My KPA500 receives serial data (listen only) from my TS-590 and follows TS-590 band changes without needing RF input.   If I connect the KPA500 and KAT500 with an AUX cable will the KAT500 be selected to the same band as the KPA500 before receiving RF input? If so, what minimum pin connection set is required?


Asked another way - Is a K3 required for the AUX bus to have any functionality?


Thanks and 73,
