Puxing PX-777 to computer audio cable for Echolink etc.

I have built a very simple but working audio cable to connect my Puxing PX-777 (and Baofeng UV-3R) to my laptop, for use as an internet gateway. I used one of the handsfree headsets that shipped with the radio as this already has the radio-side connectors.

I have used this cable with Echolink and also with Zello. This cable has no PTT-triggering, so it only works with VOX.
