CHIRP files
CHIRP is a free, open-source tool for programming your amateur radio; see the download page here. The following files are configured for Cupertino ARES operations. While frequencies are listed in a specific order, you can re-arrange them to suit your particular setup. Also, if you create a version for your favorite radio, please submit it for posting here.
