Software For The SignaLink


See our SignaLink USB Product Guide to find the part numbers that you need for your radio
or give our Sales Staff a call at (800) 822-9722 (Mon - Fri, 9AM - 5PM PST).


This page contains links to many different programs that can be used with the SignaLink interface.  Tigertronics in no way endorses or supports any of the programs listed here.  We have compiled this list only to help you in locating programs that are known to work with sound card interfaces.  Most programs work very well and provide excellent performance, but as you should expect, some programs will work better than others and some will not work at all with certain computer / sound card configurations.  We recommend that you download and evaluate several programs to determine which ones work best for you.  If you have questions about a specific program, or if you have trouble getting it to work with your system, then you will need to contact the author of the program directly for help.  Questions or problems with the operation of the SignaLink should of course be directed to our Technical Support Department.

How To Find What You Are Looking For

The programs on this page are listed in alphabetical order by program name.  To the right of each program name you will find information about the program, such as the modes and Operating Systems supported.  To help you find what you are looking for, we recommend that you use your web browsers "Find" feature (Netscape/Mozilla users press "CRTL-F") to search this page for specific "key words".  These keywords can be the mode that you are interested in (FT8, PSK, MT63, etc.), the program name (or any part of it), the operating system you want to use, etc.  When you find a program that you would like to download, simply click on the program name.  You will then be transferred automatically to the authors web site or another page where the program can be downloaded.


Windows OS Compatibility

In general, we have found that most communication programs that are designed to work in Windows XP also work just fine in all newer versions of Windows, including Windows 11.  However, this is not always the case, and some program developers have dropped support for Windows XP in their latest releases.  Please refer to each program's support documentation for the details on the supported OS' and other important information.


Sound card program setup for the SignaLink USB

Be sure to see our instructions for configuring your communication program.  If we don't have the program that you are using listed, then be sure to see the "General Setup" section as it applies to ALL sound card programs.
