This PWM signal is a digital signal we can now transfer using those generic 433MHz modules. Obivously because of the low transfer rate, we can only use a modulating frequency of (I tested and found working) around 10kHz. Therefore the audio quality is bad, but certainly enough for voice. With 10kHz, I even got a range of more then 100m!
