I have not been able to determine if a Macro can be sent from the K3s to the KAT500 via the AUX cables. My goal is to send the following commands: SWH16;DE255;T; Which are intended to put the K3s in “Tune”, wait 255 ms and the put the KAT500 into the “Tune” mode. These are to be sent via the Kpod. Is this possible? Very 73 - Mike - K9JRI
