[Elecraft] N1MM and keying KX3. What happens to the slashes // Solved

[Don Wilhelm]

A way to simultaneously interface a paddle and computer to the KX3 --

The KX3 has two paddle inputs - one in the front for the KXPD3 and the 
other on the left end.
They can independently be set to either Hand or Paddles.  Yes, if you 
want to use the front one with anything other than the KXPD3, you will 
have to create an adapter.  Several suggestions on how to accomplish 
that can be found in the archives.
So you can end up with one input for the computer generated code and 
another for paddles.
