[Elecraft] KPA500+KAT500 interfacing

[Andy Durbin]

"If I was to replace the K3S with a rig with only RS232 control of the KPA500, will the Kat500 still follow along using the Aux cables."

I'm pretty sure the answer is "No".  AUX cables don't do anything unless connected to an AUX compatible rig.  It is, however, easy to feed the KAT500 with the rigs responses to KPA500 interrogations assuming the rig is Kenwood or Kenwood compatible.  The KPA500 can be configured to poll for IF, FA, and FB.  KAT500 is wired to listen to the FA responses.

Email me for a cable sketch if you need it.
