Yes. It must be disconnected. The K3 is loading the band and PTT inputs to the KPA, pulling them low. This has two effects - it will cause the KPA to change to 60 meters, and the KPA will transition into transmit. If you wish to use the KPA500 with another transmitter, you will need to first disconnect it from the K3.
