Airlink Express is end-of-life

Version, released on 10/28/2021, is the final release of Airlink Express. The software was offered, free of charge, as an alternative to other software that would not support the "new" Windows sound architecture, introduced with Windows Vista. The number of folks using Airlink Express has reduced dramatically over the past few years, not in the least due to the advent of newer digital modes, and more modern software has been available for some time now.

The Airlink Express software and this website will remain available indefinitely, or at least for another 10 years. :) End-of-life does not mean that Airlink Express is now public domain. The copyrights of the software and website remain with me.

I would like to thank everyone who has offered advice, suggestions, and supported Airlink Express over the past dozen years or so. I'm truly grateful for that!

Airlink Express Box Airlink Express is a user friendly digital mode software package for the Amateur Radio Operator. The software is compatible with Microsoft Windows XP, Microsoft Windows Vista, and Microsoft Windows 7, 8 and 10. It offers PSK, MFSK and RTTY digital modes with logging and macro capabilities. If you have ever used the Digipan software you will be immediately familiar with Airlink Express.

With the release of Windows Vista and Windows 7, Microsoft introduced a new sound architecture. Airlink Express is developed to support this new sound architecture, yet it maintains complete backward compatibility with Windows XP. Airlink Express brings back the familiar volume slider interface you've become used to from older Windows versions.

The DSP engine used in Airlink Express is MMVari by Makoto Mori, JE3HHT. This engine is very flexible and decodes as well, if not better, than any other soundcard mode engine currently available. It is used by many other software products like Logger32 and the N1MM contest logger.
