DescriptionWSPR implements a protocol designed for probing potential propagation paths with low-power transmissions. Normal transmissions carry a station's callsign, Maidenhead grid locator, and transmitter power in dBm. The program can decode signals with S/N as low as -28 dB in a 2500 Hz bandwidth. Stations with internet access can automatically upload their reception reports to a central database called WSPRnet, which includes a mapping facility.

Most operators will be best served by using WSJT-X for WSPR as well as for any of the two-way communication modes. WSPR 2 is showing
its age but is still perfectly usable. It may be
especially desirable if you need a lightweight program
that runs on older computers. It features a
user-friendly setup screen with drop-down selection of
audio devices and rig-control parameters, support for
compound callsigns, fine selection of the fractional time
for transmitting, and a Tune
button. A new Advanced setup screen offers
optional CW identification and tools for frequency
calibration and automated frequency corrections for your
radio. Full details are presented in the WSPR 2.0 User's Guide.
Binary installation package is made available for Ubuntu
Linux (versions 8.10 and later), Debian 5.03, and other
Debian-based 32-bit Linux distributions. WSPR 2.11 and WSPR 2.12 include
these enhancements over WSPR 2.0:
