[Elecraft] K2 auto-detect feature

[Bob Tellefsen]

Vic
I built a little keying adapter in a small can to do this.
It has two jacks, one for my paddles and one for the
keying lead from my TR Log laptop.  The laptop jack in mono, 
and the paddles jack is stereo.  The output is
a three wire lead to the key jack in the K2.

Inside the can are the two diodes that steer the single
keyline from the laptop to both the dit and dah lines
to the K2.  The paddles connect direct to the dit and dah
lines.  It's been working just fine at any speed I can handle.

Go for it.
Good luck and 73
