In an effort to consolidate some posts from elswhere, here is one I wrote in 2020 about the uBitx v5 I built.

This was my first HF radio, and I made lots of great contacts on it before I upgraded to an Icom IC7300.

Some quick details on modifications I made to this radio:

  • IF Tap to use an external SDR as a panadapter
  • Switched RX port, shares antenna with a wide bandwidth SDR, grounds on TX
  • DSP S-Meter/Spectrum Scope
  • KD8CEC Firmware
  • 3.2" Nextion Touch SCreen
  • P-Channel MOSFET reverse polarity protection & fused power input
  • Built in USB Soundcard
  • External tuner control for my LDG antenna tuner.

Enjoy!
