Testing your remote session from a PC or Mac

If you still have your audio hooked up, you can use the Python text mode Internet radio application by performing the following steps.

  1. From your command line, enter cd radio/bin.

  2. Enter python3 radio.py to start the application.

The Internet radio should now play your selected station.
