QRadioLink is a Linux software defined radio transceiver application using VOIP for inter-communication, built on top of GNU radio, which allows experimenting with software defined radio hardware using different digital and analog radio signals and a friendly user interface.
Its primary purpose is educational, but it can also be customized for low power data communications on various frequency bands. It can also be used as an amateur radio SDR transceiver for demonstrating radio communications to students.
The application was originally inspired from the Codec2 GMSK modem project by Kristoff Bonne.
