[Elecraft] KX3 RTTY Mac Software

[Bill Frantz]

I mostly use cocoaModem for RTTY and other digital modes. I have 
also used fldigi. For both programs, I use a SignaLink USB as 
the interface between my MacBook Pro and the K3 with a home brew 
cable that connects the SignaLink to the Line In and Out 
connectors on the back of the K3. I use a separate connection 
for PTT from the SignaLink to the PTT In connector on the K3. 
This last connection lets me switch between voice and digital 
modes without changing the K3's VOX setting. (Note that in this 
configuration, the SignaLink is performing the VOX function.)

For RTTY, I run the K3 in AFSK A mode. I use DATA A mode for all 
other digital modes.

I have a preference for cocoaModem over fldigi. I think I get 
better decoding from cocoaModem, but my preference may be mostly 
that I am much for familiar with cocoaModem than with fldigi.

cocoaModem is well integrated with both RUMlog, a DX and general 
purpose logging program, and RUMped, a contest logging program. 
All these programs are no cost and source code is available for cocoaModem.
