Development of CHIRP is an all-volunteer effort and is offered as open-source software, free of charge. If you like CHIRP, please consider contributing a small donation to help support the costs of development and hardware:

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.

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

Windows Users

  • The file is for advanced users wishing to run CHIRP without installing

MacOS Users

  • New Mac OS X must install the runtime once before running CHIRP. After it is installed, the runtime does not need to be downloaded or installed each time. Download the KK7DS Python runtime for Mac OSX.

Ubuntu Linux Users

If you are using Ubuntu linux (or a compatible variant such as Mint) you should install and use the PPA like this:

sudo apt-add-repository ppa:dansmith/chirp-snapshots
sudo apt-get update
sudo apt-get install chirp-daily

After installing the build from the PPA, new updates will be included in your normal system software updates. Also see the Running on Linux page for additional steps required to gain access to your serial port.

If you don't run a distro for which we have packages, you can run CHIRP right from the tarball available through the link above. Most modern distributions should have almost everything required to run chirp. Make sure you have python-serial and python-libxml2 packages installed. For more information about using CHIRP under Linux, see the Running Under Linux page

Live CD

A Linux-based LiveCD is available with CHIRP pre-installed. This will boot on almost any system and provide a highly-compatible CHIRP environment without the need for fussing with a driver. It will not modify your system in any way.
