[Elecraft] KAT500 and KPA500 integration

[Jack Brindle]

To the last question - Yes. The KAT500 and KPA500 do not communicate through the AUX bus. Further, KAT500 is listen only, KPA500 is talk only, and KAT500 cannot listen to the KPA500 data.

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?
