The instructions for an SO2R box in the rear portion of the manual for the
NA Contest Logging program include a diagram. I constructed this one about
10-12 years ago, have used it many times on both modes, and it works
excellently to this day.

Here's another way to make an so2r audio box.
Get one of these:
http://tinyurl.com/cubu5vj
Left radio audio goes to red/white of input 3
Right radio audio goes to red/white of input 1
Use a wye adapter to jumper input 2 red to input 1 red
Use a wye adapter to jumper input 2 white to input 3 white
Use a male RCA to female stereo 1/8" adapter on the output for
your headphones.
Here's the best place to get quality cables and adapters at great
prices:
