The linked article has some great introductory information.
M17 is a new digital radio protocol designed for amateur radio use. It's distinctive for being completely open-source, contrasting with the proprietary nature of existing digital radio modes. The protocol employs Codec 2 vocoder for voice digitization and uses 4FSK modulation for transmission. It operates within a 9 kHz bandwidth, has a 12.5 kHz channel spacing, and a data rate of 9600 bits per second.
Key features of M17 include:
1. Open-Source Nature: It's developed and maintained by the community, with its code and documentation freely available on platforms like GitHub.
2. No User Registration Required: Unlike other systems that need specific user IDs, M17 uses the operator's callsign for identification.
3. Support for Data Services: M17 can transmit text messages and positioning data along with voice.
4. Wide Application: The protocol supports various devices and software, and can be used with modems, portable radios, and even Android apps.
5. Community Project: It's a collaborative project with contributions from amateur radio enthusiasts, fostering innovation and experimentation in digital radio communications.
