Can I wire a K3s to a KAT500 via AUXBUS cable, then RCA cable from KAT500 to AL-811H amplifier for PTT, and will the KAT break the PTT line if the SWR is above the configured value in the KAT? I don't want to test this as the AL-811H has no built-in protections. Thanks for your help! 73 Eric WD6DBM
