Don't know if anyone is using this ..... I just found it.

I found a little program called Smart Propo that works with W2000. It plugs your Futaba/Hitec/JR into the sound card. Put a 10k resistor across the signal & ground on the trainer port,and a 1/8th inch jack on the other. The ppm subcarrier audio tones are detected as different command inputs.

Here's one website, I'm still looking for the better one with the cable picture.
