I did some experimenting. Here are my results. Steps to reproduce: 1. Obtain a male to male 1/8" stereo cable. And a jumper clip cable.
2. Plug one end of stereo cable into the KX1. Make sure KX1 is in hand key mode. 3. On the other end of the stereo cable, short the center of a stereo plug to the ground end. I did this by overlaping one alligator clip over the two contacts. 4. Just tap the tip of the stereo plug to the ground lead. (the other end of the jumper clip). Now the transmitter is constantly keyed on. I think this is a bug. It should be more forgiving when in hand input mode. It should ignore the RB3 signal on the MCU in hand input mode. Only ground and RB2 should work. The way it is now it's like a booby trap waiting to spring on you. I discovered this feature on Field Day. Much to my dismay. 73, Mike AB6CV _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
