Some Yaesu transceivers can use a CT-27A cloning cable to copy the memory settings etc from one set to another, this page shows you how to make one. See the Yaesu Cloning Cables for other Yaesu Cloning cables.
2 × 3.5mm 4 pole type plugs and some 2 core cable (about a meter) are required.
Just connect as shown in the diagram below:
