Here's a quick list of pages I found promising about using GNU/Linux for ham radio.

• https://hamwaves.com/linux.ham/en/index.html
• https://sourceforge.net/projects/kb1oiq-andysham/
• https://launchpad.net/~ubuntu-hams-updates/+archive/ubuntu/ppa/+index?batch=75

If any of you are already using GNU/Linux to run ham radio programs, please feel free to edit this page to share your experience, tips, etc.
