	Exploring digital modes can be done with a Linux or Windows computer, or with a phone. A radio helps, but is not necessary to get your feet wet.		Exploring digital modes can be done with a Linux or Windows computer, or with a phone. A radio helps, but is not necessary to get your feet wet.

			The setup consists of two parts. The first part is a computer or phone: this turns digital information into analog signals that can be sent out over the radio (via the device's soundcard). The second part is a radio, which receives the analog signal from the computer and transmits it, or receives an analog signal and sends it to the audio input of the digital mode program.
