[Elecraft] KX3 AND FSK

[Don Wilhelm]

Noel,

The KX3 does not have an FSK input.  You will have to move up to the K3S 
to have that.

You cannot use a CW Keyer (external) for FSK - you must use paddles 
directly attached to the internal keyer in the KX3.

The easiest way is to use AFSK A data submode along with a soundcard and 
a computer.

If you have a computer application that can send ASCII text (via the 
"KY" commands (see the programmers reference manual), then you can send 
in FSK D mode.

Despite what is often said about soundcard generated AFSK, in the 
K3/K3S, it is actually cleaner than FSK.  I figure that is also true of 
the KX3, although I do not have any data on that.

73,
