WSPR DIGITAL RESOURCES

WHAT IS WSPR:

WSPR is designed to measure and report on the propagation of weak radio signals.

How it works:

WSPR transmits a coded message, including the sender's callsign, location, and power, using a very slow data rate and a specific modulation technique called 4-FSK (Frequency Shift Keying).

Transmissions:

WSPR transmissions are typically very short and repeated at regular intervals.

Reception and Reporting:

WSPR signals are received by other amateur radio stations with SDR (Software Defined Radio) receivers, and the decoded data is automatically reported to a central database (WSPRnet).

WSPRnet:

WSPRnet provides a map of the WSPR signal reception and is used to visualize propagation paths.

Applications:

WSPR is used by ham radio operators to explore propagation characteristics, optimize antenna setups, and understand how radio waves travel over long distances.
