[Elecraft] K2: Positive or Negative CW Keying? Again

[Jack Brindle]

Bernie;

Winkey works just fine with the K2. Just hook it up. You should  
follow the connection diagram shown in the K2 manual, either  
connecting tip and the small ring together or using two 1N4148 diodes  
on each side to make sure the two circuits get shorted to ground at  
the same time. This eliminates the need to change the key menu  
setting when going to "hand key" mode, which Winkey needs.
