[Elecraft] How is handkey plug wired for KX-1?

[Don Wilhelm]

Paul,


Yes, to key the KX1 from a hand key or a properly working computer 
keying circuit, you connect between the sleeve and the tip of the 1/8 
inch stereo plug.  Note that a mono plug will not work, it must be stereo.

I cannot equate the "48 character display" to a KX1 problem.  That 
sounds like a computer problem.

If you leave the KX1 set to HND and tap out CW on the dot paddle, does 
your KX1 key properly?  If so, then it should also key with your keying 
interface.

When you send from CWType, what do you hear with the KX1 sidetone?  That 
should be what is being transmitted.
