[Elecraft] KX3 And SignaLink USB

[David Ahrendts]

Hey Dale, I’m successfully using FLDigi on a Mac Mini, the SignaLink USB device and the KX3/PX3. Use the RED TRS (tip, ring, sleeve) mini-plug (or any similarly wired cable) and plug one end (the straight plug is my preference) into the SPKR output of the SignaLink device, and the other end (right angle mini-plug) into EARPHONE plug on the KX3 — this is receive line.  For the transmit line, you may have to home build, but it is easy as pie. In my case, I have an RJ-76 out of the SignaLink device into an adapter that connects to a right angle TRS mini-plug which plugs into the KX3 MIC plug — this is the transmit line. 
I prefer using the SignaLink device because it does a wonderful job of isolating the KX3 from the Mac Mini (I think that’s important), and it regulates input and output levels really well. I do place a cheap external speaker on the SignaLink box, AUX output, so I can simply hear the digi-data back and forth in the background at a really low level.
Happy to provide any guidance off list including photos, etc. The home brew transmit cable cost six-bucks, a modified MIC cable.
