[Elecraft] K3 / KX3 Key Jack

[Don Wilhelm]

Joel,

Use a stereo plug for both the K3 and the KX3.  Connect the keyer to the 
tip and the sleeve on both plugs (no connection to the ring) and it 
should work just fine.  Set the KX3 menu to Hand.

Yes, it does not matter to the KX3 whether the tip or ring are used, but 
connecting only to the tip will allow use of the plug into multiple 
transceivers with no changes.  Many will not work with keying to the 
ring contact.
