Stations using this system transmit an inaudible stream of data in addition to the normal radio signal. RDS data contains various information, such as AF (Alternative Frequencies for the same program station), PI (Program Identification), PS (Program Service station name), PTY (Program Type name), etc. [. . . ] There are continuous crackling and hissing noises. There are buzzing and whining noises (especially in the evening). These noises result from lightning, fluorescent lamps, motors, thermostats and other electrical equipment.
