Does it happen when the paddle is NOT plugged in?
If not, suspect the paddle jack.
FWIW, I also used this method to allow the K2 to be keyed by the N1MM
program. I mounted the diodes on the control board of the K2 and brought
out the keying line via the ALC pin on the DE9 connector, since I nev
I have the external circuit using two diodes to allow the K2 to detect when
a straight key is used instead of the paddles. Occasionally with the paddle
plugged in but not keyed, the K2 will spontaneously start sending a string
of dashes. This will terminate, sometimes only briefly, when I do key t
