Yaesu CAT control and Digital mode interfaces to use software such as Ham Radio Deluxe, FLDigi, WSJT-X to operate PSK31, FT-8, JT9, JT-65, Echolink and many other AFSK modes.


External USB Sound Card isolated audio interface allowing you to operate many AFSK digital modes such as PSK31, FT8, JT9, JT65 and Echolink. Fully plug and play. Simply plug the USB cable into your PC and the Data plug into your transceiver.

Perfect with digital mode applications such as DM780, WSJT, FLDigi, Echolink etc.

The interface uses the C-Media CM108 USB Audio Chipset and most modern operating systems already have the driver pre-installed. The advantage of this interface is your PCs normal soundcard is not tied up for Digital mode operations. As you now have a separate and dedicated soundcard for your Digital Mode working, you can independently set the Tx/Rx audio levels leaving normal PC sound unaffected.

The interface is fully galvanically isolated between PC and Radio. The Tx/Rx audio signals are isolated by Bourns 600:600 Ohm transformers and the hardware PTT is opto-isolated. The PTT is keyed by an internal VOX circuit in the interface. 

Cable length is 1.5m from the USB and audio connectors 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.

Yaesu Transceivers either have a combinations of CAT and Data connectors. Use the Options drop down menu to select the cable you need.
