[Elecraft] K2 hand key problem

[R Thompson]

   I was looking to make a contact with my hand key when I ran into an
unusual problem.  As soon as a I closed the key it locked down in
transmit.  Thinking that there was a problem with the key, I tried
another with a different set of long leads, and had the same result.
Then I tried the leads without the key attached, as soon as I touched
the leads together it locked down into transmit again.  The same keys
when connected to the key jack with shorter shielded wire worked OK.
Has this problem come up before?
