WebChirp. Like noise, it is sometimes useful to play a chirp signal against a receiver. One of the gnuradio tutorials does this in a clean way using a probe. The probe follows a triangle wave level and modifies a sine wave's frequency with that value. As a learning exercise, I wanted to incorporate custom code in gnuradio. WebThis plugin has been designed to work in conjunction with the ChirpChat demodulator plugin that should be used ideally on the reception side. It has clearly been inspired by the LoRa technique but is designed for experimentation and extension to other protocols mostly inspired by amateur radio techniques using chirp modulation to transmit symbols.
