Open Source Amateur Radio.
We are M17.

M17 is a community of open source developers and radio enthusiasts. We're building understandable systems in support of the hackers and experimenters' history of ham radio.

Open Source Digital Radio

Our Current Goal

/user/pages/01.home/02._our-current-goal/m17glow.png

M17 is developing a new digital radio protocol for data and voice, made by and for amateur radio operators.

Our protocol's voice mode uses the free and open Codec 2 voice encoder. This means there are no patents, no royalties, and no licensing or legal barriers to scratch-building your own radio or modifying one you already own.

This freedom to build, understand, and innovate is core to amateur radio, but has been missing from the commercially available digital voice modes. This is part of why amateur radio digital voice modes have largely stagnated since the 1990s and we're almost wholly dependent on commercial products that aren't well designed for amateur radio users.

M17 is about unlocking the capabilities that amateur radio hardware should already have.

Here you will find people working on radio hardware designs that can be copied and built by anyone, software that anyone has the freedom to modify and share to suit their own needs, and other open systems that respect your freedom to tinker.

In Support of The M17 Project

Grants

/user/pages/01.home/04._grants/ARDC-Logo-lg.jpeg

Amateur Radio Digital Communications (ARDC) is a private foundation that exists to support amateur radio and digital communication science and technology. ARDC makes grants that support amateur radio, funds scholarships and worthy educational programs, and financially supports technically innovative amateur radio and digital communications projects.

ARDC awarded the M17 Project $250,000 in April 2020 for RF design and development, including test equipment, prototypes, and developer kits. They will also be used to provide bounties for solutions to particularly hard problems, and for the administrative work that is less likely to get done on intrinsic motivation alone.
