Kenwood is a brand of electronics: By simply replacing the connector of the data cable with the MAX232 circuit for communication with mobile phones, we get a cable for programming the memories of the Kenwood TH-F7E/F6A handheld. I used a data cable originally for Siemens x55 series phones.
Pin 2= GND
Pin 3= Data OUT – Tx
Pin 4= Data IN – Rx
We connect everything according to the original diagram from the manual.
We will need a program: KENWOOD MEMORY CONTROL PROGRAM MCP-F6/F7 Version 0.10 Beta, which we find at http://www.kenwood.com/i/products/info/amateur/image/MFX100.exe.
