[Elecraft] K3: DIG 0

[Greg - AB7R]

DIG0-IN is pin 1 on the ACCY connection.  This is where you would connect your FSK 
keying line for direct FSK with the K3.  This should also be the same line for direct 
keying of PSK if you decide to use that.  I think most folks will use DATA-A for PSK 
when using a soundcard program.  PSK-D is there  primarily for direct sending using 
your CW paddles without the need of an external computer.
