Weak Signal Communication Software WSJT-X, WSJT, MAP65, and WSPR are open-source programs designed for weak-signal digital communication by amateur radio. Normal usage requires a standard SSB transceiver and a personal computer with soundcard, or the equivalent. SDR-style hardware including the SDR-IQ, Perseus, SoftRock, and FUNcube Dongle is supported by MAP65 and WSPR. SimJT is a utility program that generates simulated signals for test purposes. All of the programs are available free of charge, licensed under the GNU General Public License. Installation packages for WSJT-X are available for Windows, Linux, and OS X; WSJT and WSPR have Windows and Linux packages, and MAP65 and SimJT are Windows only. For further details about source code and operating systems, see the Program Development page.
