[Elecraft] CW keying circuit

[Tom Hammond]

Hi Carter:

>I want to be able to do computer-generated CW on my K2, using software such as
>DX4WIN and WriteLog. The circuit that works on my wife's Yaesu 
>FT1000 MP Mark V does not work on her Yaesu FT920, which makes me 
>think it isn't going to work on the K2, either, because both require 
>a stereo plug. The circuit for the Mark V addresses a mono plug.

>Can someone send me, or point me to, a CW keying circuit for a COMM port that

>I do not want to use a sound-card approach, such as the RigBlaster.

PC boards are $6 ppd to your mailbox.

I've used this with ALL of my rigs, including several K2s, for the 
past 15 years with no problems.
