This kit contains the essential parts required to build your own interface - one annoying aspect of datamodes is that you often need a way to control the PTT of your transceiver outside of the CAT interface. Traditionally, this could have been handled via a 9-pin RS232 port. But today it's all about USB so you either need to buy a converter or buy a ready-made (and often expensive) interface "off the shelf".

With these parts you have the main ingredients for a CW and Datamode interface - we even supply an example circuit showing you how to put it all together, but you will need to add some of your own cabling and a suitable box.

Difficulty : 4/5 - Soldering experience is essential and the kit requires an understanding of how this circuit works as well how to complete it with a suitable enclosure.

  • 1x USB to Serial Converter - choose from FTDI PCB (out of stock) or CH340 Cable versions
  • 2x Audio Isolation Transformers
  • 2x 4N35 Opto-Isolators, 1 for PTT control and 1 for CW keying
  • 2x 1N4148 Diodes
  • 1x 5mm Red LED (for PTT status)
  • 1x 330-ohm Resistor
  • 1x USB 50cm A to B cable (for FTDI module)
  • Includes build instructions
  • Just add cabling to your soundcard and radio's "data" socket plus a suitable enclosure

A great project for PSK, RTTY, JT65, SSTV and CW enthusiasts!

The USB to Serial options give you the choice of a PCB module (FTDI chipset) or USB to 9pin cable (CH340 chipset)
