CHIRP downloads¶

CHIRP is distributed as a series of automatically-generated builds. Any time we make a change to CHIRP, a build is created for it the next day. Thus, CHIRP is versioned by the date on which it was created, which makes it easy to determine if you have an older build. We don't put experimental things into CHIRP before they are ready, except where specifically called out with a warning. Thus, you do not need to worry about finding a stable version to run. You should always be on the latest build available.

Upgrading: You do NOT need to uninstall an existing version of CHIRP before installing a newer one. Just install the new one and it will replace the existing copy! However, be sure to quit CHIRP before installing the new version!

You can find a complete test report of the current build here and a matrix of supported models and features here

Most Linux users will want the flatpak executable, which has the entire runtime integrated and should "just work." If you are running an old or weird distro and want the source distribution, grab the tarball from the above link.
