[Elecraft] Digital Modes with a KX3 and a Mac

[Don Wilhelm]

Joshua,

Start out taking it one step at a time.
Receive first --
All you need to receive data modes is to connect the KX3 headphone jack 
to the soundcard line in.  Fldigi should show you some signals.  
Configure the soundcard Line In level as well as adjust the KX3 AF 
Gain.  Set the mode in the KX3 to DATA A for PSK31 and to AFSK A for RTTY.
Then RIG Control --
Next connect the computer COM port to the ACC1 jack and configure Fldigi 
to use hamlib or rigcat through that port and you should see the 
frequency on the Fldigi screen.
Then Transmit --
Transmit is the last step - connect the soundcard line out (or speaker) 
to the KX3 microphone jack and adjust the soundcard, adjust the 
soundcard output level and the KX3 mic gain to produce 4 bars solid with 
the 5th flickering on the KX3 ALC meter.

Once you have those 3 connections working you should be up and running.

73,
Don W3FPR
