Jim. Be sure to set up the KAT500 Configuration: Amplifier Key Interrupt Power = Optimize for KPA500 (not the default 30 w) Amplifier Key Interrupt VSWR Threshold = ~2.5:1 (not the default 99:1) I set the Autotune VSWR Threshold to 1.8:1 (or maybe that is the default)
In the K3 set PWR SET to Per Band and TUN PWR to nor.
