With Codec 2, David has made significant contributions to amateur radio by helping to move the community beyond the vendor controlled digital voice ecosystem and enabling other innovation previously prevented by patents. 'We are working on improving the quality, and lowering the SNR required for HF digital voice.' 'As well as speech compression software, the Codec 2 library also includes a variety of modems integrated into the FreeDV protocol to support robust open source digital voice over HF radio,' explains David. Codec 2 enables other software and hardware projects to utilize digital voice communication without the barriers of licensing, usage fees and vendor lockdown. It provides a royalty-free and open source codec suitable for digital voice application in amateur radio. Factors considered include innovation, impacts on amateur radio and community involvement.Ĭodec 2 is a foundational project for digital voice communication on HF and VHF. We had a very competitive pool of nominated projects to choose from. The award committee went through extensive consideration of all nominations received.

The Amateur Radio Software Award (ARSA) committee is pleased to announce the recipient of the 3rd annual Amateur Radio Software Award to David Rowe, VK5DGR, and his project, Codec 2.
