Project wiki and documentation

Mailing list

Note: The prior GMANE Web interface is likely permanently offline. A new GMANE NNTP server is operational and recent list mail can be seen via the news.gmane.io server (note the new host name which became active on 15 Jan 2020) as the gmane.linux.hams.hamlib.devel group. At this time the mail gateway from the GMANE news server to the mailing list doesn’t seem to be operational. See news.gmane.org is now news.gmane.io for more information on the recent change.


Hamlib has a very organic development model. Contributions (patches) are accepted after review and applied to the development branch (master), or, in the case of a bug fix to a released version, an arbitrary stable branch.

Patches may be submitted by one of several ways. Perhaps the most common is forking the Hamlib repository, making the changes to your cloned repository and then issuing a pull request.

Not to worry, the GitHub site (which hosts this page and repository) has plenty of help available to keep all of this straight.

Another way to submit patches is to post them to the mailing list where Nate, N0NB, will likely apply them and push them to the main repository. The README.developer file has some additional information.

Contributions to Hamlib come from all over the world, it seems. It is this widespread interest that keeps the project moving forward. Don’t be shy if all of this seems a bit overwhelming. All of us were beginners at some point as well, so dig in and have fun!
