Interface Key Features

  • Built-in C-Media USB Audio codec. Provides an external USB sound card to dedicate to your Digimode activities freeing up your PCs internal sound card for normal Windows duties.
  • CAT Control. Full USB CAT Control of your transceiver. CAT control allows your PC to control the frequency and mode of your transceiver and obtain the current operational state for automatic logging etc.
  • PSK31, FT8 etc. Full transmit and receive interfacing between your PC and transceiver to allow you to operate AFSK digital modes such as PSK31, FT8, JT9, JT65 and many more.
  • Fully isolated audio. Full galvanic isolation of Tx and Rx audio signals using Bourns 600:600 Ohm transformers.
  • Opto-Isolated PTT. Hardware PTT keying available over USB port using RTS signal which is opto-isolated from the transceiver.
  • Plug and Play. No additional cables required. Plugs into your PC on a spare USB port. At the transceiver, connects into CAT port and Data/Packet Port.
  • Software Compatibility. Ham Radio Deluxe- WSJT-X - Fldigi - Digipan - Echolink - MixW - N1MM and many more.
  • Simple to use. Simple audio level adjustment via operating systems Speaker and Mic level control sliders.
  • Very compact. Interface box is only 80mm x 40mm x 20mm. Sit it behind the radio and forget about it.
  • Compatibility. See the compatibility list below. You need to let me know which radio you need the interface making up for.
  • FTDI Chipset. Highly reliable FTDI USB Chipset is used in the interface for the CAT control of your transceiver and the hardware PTT keying.
  • Cable lengths. From PC to Radio is 2.1m This will allow the interface to sit out of sight using up less desk space. (PC to interface 1.5m, interface to radio 0.6m)

A Quick Start Guide (a detailed PDF instruction sheet will be sent to you when you purchase)

  • Plug USB plug into a spare port on your PC. The built-in C-Media Sound Card drivers are already built into Windows.  For the CAT setup,  download the FTDI drivers and see which comm port it picks up in Windows device manager. Make a note of this.
  • Plug Din plug into packet/data/accessory port on your transceiver.
  • Plug CAT plug into the CAT/Remote port of your transceiver.
  • Run up your favourite CAT control program such as Ham Radio Deluxe. Set CAT software to use the comm port you noted from the driver installation section.
  • Set the CAT software radio type and baud rate to match those set in your transceiver.
  • If needed, set your CAT software to PTT key via the comm port RTS signal. Most PTT via CAT commands these days anyway.
  • Set your Digital Mode/PSK31 software to PTT key on comm port RTS signal if your are using it stand-alone
  • For the new sound card device, you can use the Windows sound level sliders for line out and record in to optimize the drive levels to your transceiver and in receive. 
  • Make sure you keep your transmitter out of ALC for optimum PSK31 operation. Keeping your output stage nice and linear is the name of the game when working digital modes.
