Purchased in March 2023 for $100. I received this in partial trade for a power supply I sold so it’s surplus to my needs.
This provides USB CAT Control and Audio Interfacing of your Icom Transceiver allowing you to fully utilize software such as WSJT-X, FLDigi, Ham Radio Deluxe, Echolink, PSK31, DM780, N1MM Logger, MixW and many more.
This Digimode-4 interface provides a single USB connection to your PC and has both built-in USB CAT control and its own built-in USB Sound Card. The interface allows you to dedicate your digital mode working to the external sound card and its independent level setting controls leaving your PC’s internal card for normal Windows functions.
This interface is fully wired for your PC and transceiver. Just follow the provided instructions to download the FTDI drivers. The in-built sound card drivers are included in your operating system and the interface will pop up as a generic USB PnP Sound Device. The interface plugs into a free USB port on your PC and into your transceiver CAT and Data/PKT ports. PTT keying is via the interface built-in USB comm port RTS signal or you can choose to PTT over the CAT commands if your transceiver supports this.
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.
The 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 are 0.6m. The box is very compact at 80 x 40 x 20mm making it ideal to hide away behind the PC or transceiver using no desk space.
