RadioFoundry
Free, MIT-licensed firmware for affordable DMR radios. One shared core runs the DMR stack, the UI, the codeplug and
the host tools; each radio adds a thin board layer. It brings the FM and DMR features low-cost stock firmware leaves
out, with a UI designed from first principles. Anyone can use it for anything, commercial products included.
The website is the recommended way to install RadioFoundry and to edit your radio's codeplug. In a Chromium browser
(Chrome, Edge), plug in the radio and use the web installer to back up,
install, update and restore, and the Codeplug Editor for channels, zones,
contacts and the DMR ID database. Nothing to install, and your files never leave your computer. The command line tools
and the manual steps are for scripting and for browsers that can't talk to a radio.
