After using the kpa500 for a couple weeks everyday on cw, the amp performed like a charm. About 4 days ago when I was on 40 meters cw the tx light on the K3 started turning on and off (flickering). Turned off the K line and back on. Now I got an error message on the k3 " ERROR PTT'. the K3 was in transmit mode (tx light on). Checked all the cabling to see if they were tight. All checked out fine. Tried again same problem. Started taking off cables that where connected to the rig. Didn't clear up until I got to the Aux cable between the KPA and the K3. Reinstalled all the software on the whole K line. Turned on the rig and it seemed fine. Used it for a ragchew on 40 meters cw and it was great for about 20 min. Then the tx light started flicker again. Disconnected the Aux cable and the problem was gone. The amp works fine without the aux cable. Has anyone run into this problem?
