Operating RTTY digital mode, this resource provides access to various versions of the _2Tone_ software engine, specifically designed for decoding and encoding RTTY signals. It details the evolution of the software, highlighting a significant technical requirement change where versions 24.09b through 26.01a necessitate a PC CPU with the AVX instruction set, a crucial detail for operators considering system compatibility. The page lists numerous historical and current releases, enabling users to select a version compatible with their hardware and operating environment. The utility of 2Tone lies in its ability to interface with established amateur radio programs such as _N1MM Logger+_, WriteLog, and QARtest, enhancing their RTTY capabilities. While specific performance metrics like decoding accuracy or WPM limits are not quantified on this page, the availability of multiple versions, including those without AVX requirements, suggests a commitment to broad user accessibility. The software's integration with major contest logging applications indicates its primary application in competitive RTTY operations, where reliable decoding is paramount for achieving high scores.
