"Just gave it a try. No joy, same result - lowered rx signal strength on the IC-705. Jack indicated that the K3 sets the Vcc rail to zero volts on power off, and that is causing the amp to go into Operate mode. "
Maybe I lost the plot but wasn't the problem that the KPA500 was being keyed, not that it spontaneously went to operate mode. KPA500 won't be keyed unless one of the two keying inputs is pulled low. Take control of KPA keying source and doesn't the problem go away?
