[Elecraft] K2 CW speed

[designer]

One way to "send" cw wiht a keyboard and avoid the SSB issues is to 
use the free CWType software from DXSoft. You make a keying circuit 
with about 5 inexpensive Radio Shack parts and it will fit inside a 
larger Serial port plug. So all you have is a cable with a serial 
port plug on one end and a plug on the other to match your rig's  key 
jack. As far as the rig is knows, you are sending using your paddle.
