Hi SaMa,

First you must install the PinChangeInterrupt library in your IDE (the
Arduino/Genuino software).

The PinChangeInterrupt library is normally not installed by default. You
have to add it to your IDE by yourself. You only have to install the
library one time, once it is installed it will be kept on your pc.

In your IDE menu, go to 'sketch' => 'include library' => 'manage libraries'.
The Library Manager will be opened.
Wait for some time to collect all library information.
When it is ready: In the search box, enter "PinChangeInterrupt"
The Library Manager will show some libraries.
One of them is named "PinChangeInterrupt by Nico Hood".
Click on this library, and press the "install" button.
It takes only few seconds to install the library.
When installation is finished, press the "close" button.

Then setup the IDE correctly for the Raduino:
under 'tools' => board => Arduino Nano
under 'tools' => processor => ATmega328P
under 'tools' => programmer => AVRISP mkll

Connect a USB cable between the Raduino and the PC. Do not power on the
radio. Power to the Raduino is supplied from your PC via the USB cable.

Go to 'file' => 'open...' and browse to the folder with the raduino files
you downloaded. Find the file named "raduino_v1.27.7.ino" and open it.

The sketch code will be now be shown on your screen.
Go to 'sketch' => 'Upload'
The IDE will first compile the sketch (it will take a minute or two), and
then it will automatically start uploading it to your Raduino (this will
also take a minute or so).

When the compilation/uploading has completed succesfully, the Raduino will
restart and the new sketch version (Raduino v1.27.7) will be displayed
briefly on the LCD.

Finally, disconnect the USB cable, apply power to the radio as usual and
enjoy the improved firmware.

Happy BitX-ing!

?

If you ever want to restore the original software, you can always download it from and upload it back into your Raduino.

But the story that they say to save the calibrations and then upload them again because otherwise raduino starts from scratch?

The new software uses a different method for calibration, so you cannot use the original calibration value.
After upgrading to the new software, you must perform frequency recalibration anyway (don't worry too much about this, it's not very difficult, you can use another transceiver or AM broadcast station as a reference. See the instructions that are included with the software).
If you do not perform the recalibration, the frequency may be off by a few 100 Hz or so.

Good luck!

You're welcome.
Please let me know the result.

Sergio,

Check Raduino to BITX40 connections.

Raudino RED to BITX BROWN wire
Raduino BROWN to BITX BLACK wire
