USB Digimode Interface for your Yaesu Transceivers allowing you to fully utilise software such as WSJT-X, FLDigi, Ham Radio Deluxe, Echolink, PSK31, DM780, N1MM Logger, MixW and many more.


The Digimode-4 interface provides a single USB connection to your PC giving you full CAT control of your radio and a built-in USB Sound Card for digital mode operation. The Tx/Rx audio signals are galvanically isolated by Bourns 600:600 Ohm transformers and the hardware PTT is opto-isolated.


With this interface, you will be up and running on FT8, PSK31, Echolink, SSTV, Pactor, Packet or any mode that requires CAT control and Tx/Rx Audio Interfacing between your PC and Radio within minutes.


Cable length is 1.5m from the USB port on your PC to the interface box. The cables from the interface box to the transceiver is 0.6m. The box is very compact at 80x40x20mm making it ideal to hide away behind the PC or transceiver using no desk space.


The Digimode-4 instruction manual is here:

Option 4


Option 5
(For the  FT-847 we wire BOTH the 6 pin packer jack and the 3.5mm AFSK jack. So it can be used both on FM Packet and HF AFSK modes)


Option 5
FT-891 version
The Yaesu FT-891 has 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-891. This means you only need one USB connection to your PC to provide the interfaces external USB Sound card and utilise the FT-891's built in CAT port.
