FLDIGI and FTBCAT Configuration for uBITX

Use CEC version firmware 0.25 or later of uBITX.
The following examples are based on version 0.27.
We will post the 0.27 version as the test ends.
All of the examples below only describe connections to uBITX.
Please refer to the manual or other documents for how to use the program.

uBITX Firmware 0.27 :

1. fldigi
 Download :

 After installing the program, connect the uBITX USB to the computer.

If you installed fldigi for the first time, the following screen will appear.

Click Configure -> Rig control

Select 'Hamlib' Tab

Select Rig : Yaesu FT-817 (Beta)

Select your comport and set baud rate to 38400

Select seideband type

All settings are as follows.

Finally, check Use hamlib.

After setting fldigi, it is necessary to restart the program.
The following shows the frequency by communicating with uBITX after restarting the program.

If you click the T / R button, uBITX will switch to TX mode with the signal.

 Download :

 After installing the program, connect the uBITX USB to the computer.

If you installed fldigi for the first time, the following screen will appear.

Click Option -> Settings...

Set it as follows.

FTBCAT is a program that mainly manages memory, but uBITX has no memory to manage, so it can only view frequencies.

Click the OK Button

Click the On/Off button, then start communication with uBITX

You can see uBITX information on FTBCAT screen.

Change Band by Band buttons

Vfo Toggle by VFO A/B

The settings in the raspberry pie are the same.
The video below is a video that I tested on Windows and Raspberry.



  1. Hey Ian...what cable is used to connect the PC to the uBITX for digital operation? Maybe I'm not reading closely enough.

    I know you asked this over a month ago, but don't see any answer. As far as I can tell (and I can easily be wrong) it is the normal USB programming cable from the computer to the arduino.

  3. what other cable could it be???

Release CEC Firmware v1.200 for uBITX All version(include V2, V3, V4, V5)

Release CEC Firmware v1.200 for uBITX All Version (include v2, v3, v4, v5) I did the firmware work for v5 when uBITX V5 was released, but I release it now.
I received the feedback from a thankful beta tester and tested it myself by converting my uBITX v3 to v5 but I was not sure.

I ordered the uBITX V5 and delivered the correct uBITX V5, so I made a little more fine-tuning.
If you use V2, V3, V4, you do not need to update this firmware.

How to upgrade uBITX Firmware

uBITX is based on Arduino Nano. So uBITX's firmware upgrade method is the same as Arduino.
There are two ways to upgrade the firmware of uBITX.

The first is to compile the source from the Arduino IDE, and the second is to upload the compiled hex file using the Firmware Upgrade Tool.

I'll show you how to upload a compiled hex file as a second method.

1.Connect the uBITX's USB cable to the computer.

2.Run Device Manager on your computer.
  The way to open the Device Manager for each OS Version differs slightly.
  In most Windows, you can easily launch the Device Manager by running.

  On your computer, press the Windows key + R.

 Type devmgmt.msc and press OK Button.

On most operating systems, there will be a serial port named Ports with CH340. If so, the next step is skipped.

If the serial port is not installed as below, you need to install the driver.

Included in uBITX is the Adonano, which uses the CH340 USB To UART part.

Download the latest CH340 driver from the Internet.
