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: Windows and macOS users 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!

CHIRP-next¶

This has the latest and greatest set of features and fixes. Drivers that have not been validated with CHIRP-next are denoted by an asterisk (*) symbol on the supported model list on the Home page. This is the only version of CHIRP that is actively maintained. All users should be running the latest version of CHIRP.

Download the latest CHIRP-next build here

System requirements for CHIRP-next:

• Windows 10 and later (Intel 64-bit only^*)
• macOS Big Sur and later (universal binary with Intel and Apple Silicon support)
• Linux (all modern distros with python3, details here)

* Users report success on Windows-on-ARM using the compatibility layer, but this is not tested and compatibility cannot be guaranteed

CHIRP-legacy¶

The "legacy" build of chirp contains support for some drivers that are not yet fixed in CHIRP-next due to ongoing development efforts. However, it no longer receives any updates, including new models, bug fixes, etc. If you have a radio that does not work in CHIRP-next because it requires attention, you may choose to run the older legacy version as a temporary measure. However, please report a bug if your radio does not work with -next and help us get it converted. Windows users may want to download the .zip file and keep it separate from their installed version of CHIRP-next.

It is not advised to use CHIRP-legacy unless you have a specific reason to do so.

System requirements for CHIRP-legacy:

• Windows 2000, XP, Vista, 7, 8, 10, and 11. Older versions of Windows are not supported
• macOS Intel and Apple Silicon, but requires installation of Python 2.7
• Linux via flatpak
