Make a Yaesu CT-27A cloning cable.
By Brian, MW0GKX.

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:

To Fit:

FT-10, FT-40, FT-50, FT-60.

VX-1, VX-2, VX-3, VX-5, VX-6, VX-7, VX-10, VX-14, VX-110, VX-120, VX-127, VX-130, VX-131, VX-132, VX-150, VX-170, VX-177. and may be more.

Remember on 2 same model radios can be cloned!

NOTE: There are 3 types of this plug used by Yaesu on the various models:

  1. With a screw thread to lock it to the radio.
  2. A plug with a thumbscrew strain relief.
  3. Just a "normal" plug.
The "normal" plug will fit the socket with the strain relief.
I have been told that a "normal" plug will fit in the screwed type socket if the body of the plug is small enough to fit in the recess, otherwise the pinout is the same.
The screw type will not fit the non screwed sockets.

See: Mic Wiring Pin Outs, FT-10... page for full details of this socket connection.

This lead also fits some Alinco radios.
