A CW beacon implemented in C language on a AVR AtTiny13A microcontroller (1KB flash!).
Include a CW parametric modulator/keyer, an emulated I2C periferal and a device driver in order to handle the Si570 oscillator by Silabs.
You can personalize the transmitted message and the morse speed (in WPM).
In the example the beacon is IQ6MC/B JN63RH @ 144.450MHz.

Enjoy this example and if you will appreciate it, please sens me a feedback!
