ION2G: Staying connected without dependence on infrastructure

ION2G is communications terminal software that brings HF Automatic Link Establishment (ALE) MIL-STD-188-141B and CCIR-493-4 (SELCALL) to your computer with a familiar and easy to use graphical interface. ION2G helps you stay connected to the people you need to communicate with across thousands of miles without dependence on infrastructure. Using ALE and smart algorithms, ION2G automatically finds HF radio communications channels through the constantly changing ionosphere -- while avoiding busy HF frequencies and interference. ION2G takes the guesswork out of finding a frequency to use and will find usable radio channels that even experienced HF operators may miss.

Includes full ALE 2G controller, propagation analysis, radio control, and tactical chat.

ION2G is interoperable over-the-air with ALE 2G and SELCALL radios from all major manufactures, including Codan, Barrett, Icom, Yaesu, and Kenwood.

ION2G is cross-platform and runs on Windows 10, Windows 11 (64-bit), Linux, and MacOS. ION2G can be used with radios from manufactures like Icom, Yaesu, Kenwood, and others. New radio support is under active development.

Low cost licensing is available for non-commercial, non-government, volunteer use. If you need licensing for commercial or government applications, please click here to contact us for information
