[Elecraft] K3 auto transmit - W7RIP

[Rip R]

My K3 works like a charm and I have never had an issue with it. But
recently after I turn the rig on or shortly after I turn it on, it will
automatically transmit a series of 5 or 6 cw dashes evenly spaced (good
fist) and at about 15 wpm. This will not occur again until the next time
the rig is turned on. I do not know why it is doing this, but I would like
to know. Ideas?
