I have started it to assembly in the temporally case my bitx40.

Also I have loaded it sketch raduino_v1.15 by Allard PE1NWL. The sketch provides additional features such as USB, CW, RIT/SPLIT etc. but these will only become functional when the related (minimal) hardware mods are made. I have make for the moment the modification for CW carrier.

This project has base on the  K3NG Arduino keyer open-source firmware adding many features and flexibility.

The firmware is open source code provided by K3NG so you can customize it to fit your needs.

The Keyer is suitable as a standalone keyer or for keying the radio via the USB port from a connected computer and your favoured contest logging software or for daily operation.


  • CW speed adjustable from 1 to 99 WPM
  • Programming and interfacing via USB port (“command line interface”)
  • Logging and Contest Program Interfacing via K1EL Winkey 1.0 and 2.0 interface protocol emulation
  • Optional PTT outputs with configurable lead, tail, and hang times
  • Up to 12 memories with macros
  • Serial numbers
  • CW keyboard (via a terminal server program like Putty or the Arduino Serial program)
  • Speed potentiometer (optional – speed also adjustable with commands)
  • QRSS and HSCW
