F4HWN Firmware with CW Beacon

This is an implementation/demo of the CW beacon. A custom string can be set and it will chnage each charactors into the morse code tones while transmitting it. PS: Bandscope was replcaed to this due to the capacity issue.

Use Case

I made this mainly for the FOX HUNT beacon purposes. The modulation is FM, so most of all receivers, handhelds can receive it without any problem.

How it Works?

• App is opened using F+5 Key combination.
• Power levels can be adjusted using the up down arrow keys.
• Then press menu key to activate TX. It will convert the string set to morse codes and TX at a speed of 10WPM. At the moment, the customization of the string is only possible by chnaging the source code.
• Press Exit to stop the TX.

How to Configure?

Step 1

Open up a codespace for this repo.

Step 2

Locate to "app/morse.c"

Step 3

Edit the string at the following line (25).

char* cwid_m = "DE N0CALL"; //Edit this Message

Step 4

Compile the firmware by typing the following in the terminal:

./compile-with-docker.sh custom

Step 5

When the compilation is done, you will see a folder "compiled-firmware" generated in the Explorer section. Simply open that up and right click on any of the .bin file then Download.
