Sorry about that Don. I didn't realize that until I went back and started the K2 up again to looki for symptoms. I am disassembling the K@ today and I will look for soldering issues. I will pay special attention to U2 as it controls all the buttons and knobs. As I mentioned before, the Keyer knob seems to work normally and the power knob at least causes the P number to change but it also causes the Keyer speed number to change somewhat. I have yet to find any button, other than the power on-off button, that responds. Thanks for the help and I will report back.
Don: as a matter of courtesy, do I respond back to you or the group?
