XGGCCOMMS.COM product highlights and reviews

Below I have picked some reviews and guide videos for our very popular USB-Digimode-4 Digimode Interface.

The Digimode-4 works with Icom, Yaesu, Kenwood and Xiegu transceivers. Perfect for PSK31, FT8, JT9, JT65, Echolink and any other AFSK modes.

Compatible with Windows, Mac and Linux systems, it connects to your PC via USB and has both an external USB Sound Card and CAT interface built-in. Unlike other similarly priced products available, our Digimode-4 has transformer isolated Tx/Rx audio and opto-isolated PTT (so no ground loops!!) and we use the highly reliable FTDI chipset for the CAT.
