I guess the K3 just likes your bug!
First, make sure the contacts are mating squarely. Then measure the
continuity when the dot contacts are resting closed. It should be a
dead short. If there is any resistance find out where and correct it.
Assuming that is okay, how many dits does the bug generate when you
thumb the dot paddle? Try adjusting the dot contact spacing so that
you don't get more than about 15 maximum. (No, you do not want 20 or
30 or more dits before the contacts finally come to a close.)
You can also try wedging a piece of cotton or felt in the "U" of the
dot spring.
73,
