WJST-X configuration for uBITX

Use CEC version firmware 2.5 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.

 Download :

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


 Click File -> Settings...

 Select Yaesu FT-817 from the Rig selection menu.

Select the serial port to which uBITX is connected.

When uBITX is connected to the USB port of the computer, the virtual serial port appears in the control panel.

The baud rate is set to 38400.

PTT Method selects CAT.

Please make other settings as shown below.

Then press the Test CAT button.
Maybe there is a timeout error.
Raduino (problem of Arduino) has the problem that it is automatically reset when first serial port is connected after power is supplied.
I've posted a troubleshooting article on my blog. If you want to solve it, please read it.
But I just use it. There will be no problem after that.

Press the Test PTT Button

Then, Your uBITX should be changed to TX mode as shown below.

Press the OK button.

The frequency of the main screen of wsjt-x may be changed automatically.
I selected the JT-65 mode and the frequency was automatically changed to 14.076.000.

Now you can have a happy ham life with wsjt-x and uBITX.

If you select a band on wsjt-x, your uBITX will automatically change its frequency and mode.
It is important. If only PTT is connected without frequency synchronization, wsjt-x may be recorded as an incorrect band when it records the log automatically.

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

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.

uBITX (HF Transceiver for HAM) arrives and Assemble - (Assemble uBITX)

UBITX ordered a week ago arrived via DHL.
UBITX is simple HF Transceiver for Amatuer radio, but it have all mode and all band functions.

The uBITX main board and parts have been safely contained in plastic box.

Parts List

All parts were shipped correctly.

uBITX is pre-assembled with most parts as SMD.

Make the power Connect.

Connect the encoder to the cable.

Connect the CW Key Connector (Straight) to the cable. If you use CW Paddle, use a different resistor value.

pull-up by connecting the resistance value to the + line as shown below.

I finally connected most of the small parts.

Connect LCD and supply power.

It works perfectly with parts connection for about 30 minutes ~ 1 hour.

How to use uBITX Manager for original source code

This is a guide for uBITX's original firmware (or source code) users to use uBITX memory manager.
Unfortunately, the original source can not be used as it is.

If you use my firmware (CEC Version) that I distribute today, do not read this article. This is because CAT communication as well as memory control is fully implemented.

Again, this article is for those who are using the original source code.

You can use uBITX Manager by adding a few lines to the original source code.

You can choose one of 3 ways.
1. Adding Protocols to the Original Firmware
1.1 It's the easiest way.
  Click the link below to download the firmware. And you can update.

  How to update the firmware can be seen by clicking the link below.

  The compiled firmware is only a protocol that allows memory access to the original source.
You can recover to the original at any time as instr…
