You could inspect it and make steps manualy in case of any doubt. You can note that /boot/config.txt should be prompt to be modified during the installation. 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.
