Option 6
FT-710 and FT-891 version
The Yaesu FT-710 and FT-891 have a built in USB CAT port. This version of the interface does not have the built-in FTDI UART but instead passes a USB channel through to a USB Type B connector to plug directly into the CAT port on the FT-710/FT-891. This means you only need one USB connection to your PC to provide the interfaces external USB Sound card and utilise the radios built in CAT port.
