A fork of the KD8CEC uBITX code base to create my "uBITX V5D" (D for "Digital"), which contains an additional Teensy 3.2 microcontroller to perform audio DSP.

#uBITX uBITX firmware, written for the Raduino/Arduino control of uBITX transceivers This project is based on https://github.com/afarhan/ubitx and all copyright is inherited. The copyright information of the original is below.





  • Program optimization reduce usage ram rate (string with M() optins)
  • Optimized CAT protocol for wsjt-x, fldigi


  • added delay_background() , replace almost delay() to delay_background for prevent timeout

  • cat library compatible with FT-817 Command switch VFOA / VFOB, Read Write CW Speed Read Write CW Delay Time Read Write CW Pitch (with sidetone) All of these can be controlled by Hamradio deluxe.

  • modified cat libray function for protocol for CAT communication is not broken in CW or TX mode

  • Ability to change CW Delay

  • Added Dial Lock function

  • Add functions CW Start dely (TX -> CW interval)

  • Automatic storage of VFO frequency It was implemented by storing it only once when the frequency stays 10 seconds or more after the change. (protect eeprom life)


  • fixed screen Update Problem
  • Frequency Display Problem - Problems occur below 1Mhz
  • added function Enhanced CAT communication
  • replace ubitx_cat.ino to cat_libs.ino
  • Save mode when switching to VFOA / VFOB


  • fixed the cw side tone configuration.
  • Fix the error that the frequency is over.
  • fixed frequency display (alignment, point)


  • original uBITX software (Ashhar Farhan)
