[Elecraft] [OT] K2 & Navigator Interface

[Stan Rife]

I made my own cable. I used the 1/8" stereo plug for the RCV audio, and I believe I use a 1/8" mono for the TX audio because I have one of the Heil microphone adapter cables that breaks out the Keying and TX audio ckts to seperate 1/4" & 1/8" jacks accordingly. Made it pretty simple versus having to wire up a mic plug and switch that out all the time. I use a series of 1/8" & 1/4"  (RadioShack) Y adapter cables and have my Heil headset hooked up all the time as well as the audio cables from the Navigator. Actually I have to disco the TX audio plug from the headset to eliminate the open microphone on TX while using the Navigator.
   
  I used stereo and mono cables from Radio shack that were already made up. I just cut them in half and used which ever half had the right connector on it and soldered them all in to a DB25 male connector. Turned out kind of professional looking. That is probably the expensive route to go, but it still didn't cost the 48 bucks that US Interface wants for a made up cable. Since I was using the Heil microphone adapter cable, I would have had to modify their cable anyway.
