FreeDV

Topics
- FreeDV is a low-bit-rate digital voice mode for HF radio. Initially developed by David Rowe, VK5DGR, an international team of radio amateurs are now working together on the project. FreeDV is open-source software, released under the GNU Lesser Public License (LPGL) version 2.1. The modems and Codec 2 speech codec used in FreeDV are also open source. Hardware and software developers can integrate FreeDV into their projects using the FreeDV API. To operate FreeDV, radio amateurs either run the FreeDV GUI application on Windows, Linux and OSX machines or use the SM1000 FreeDV adaptor. Either method allows hams to use a single-sideband HF radio to send and receive FreeDV signals.
