Loose connection in the supply line will do that. It only takes a momentary open to shut the K3 down until the POWER button is reset.
Do you have a fuse in the supply line? Fuses often fail that way. Even running within their spec, they get warm in use. A defective fuse may open circuit from the heat and, when you cycle the power supply again, it has cooled and reconnected the circuit. Such a fuse will fail completely before long, but some will act that way for a while. If you are at a FD field site, severe RF feedback can result in unintended commands to the uP in the K3, which might include an OFF command. Just a few that come to mind. Hope you find it soon or it doesn't interfere with your FD score! 73, Ron AC7AC -----Original Message----- This has not happened to me before.... Running some FD here on CW for about an hour in an AC room PA 35C FP 31C The rig just went off. Dead. Power supply is ON. Pressed the power button....comes back on. Anyone see this before....I have not. Lee In our day and age it seems that Common Sense is in short supply. If you don't have any Common Sense - get some Common Sense and use it. If you can't find any Common Sense, ask for help from somebody who has some Common Sense. Is Common Sense divine? Common Sense is the image of the Creator expressing revealed truth in my mind. - John W.
