What is a WSPR receiver?
What is a WSPR receiver?
What is it? It’s a receiver for a fixed frequency on a shortwave band (versions from 3.5MHz to 28MHz available).The fixed frequency corresponds to the receive WSPR frequency on a particular band.
What is WSPR used for?
WSPR (pronounced “whisper”) stands for “Weak Signal Propagation Reporter”. It is a protocol, implemented in a computer program, used for weak-signal radio communication between amateur radio operators. The protocol was designed, and a program written initially, by Joe Taylor, K1JT.
What are the WSPR frequencies?

How long are WSPR transmissions?
110.6 seconds
The structured WSPR transmission sends 50 characters in 110.6 seconds, beginning one second after each even minute.
How do I get started with WSPR?
Start WSPR and select Station parameters from the Setup menu. Enter your callsign and 6-digit grid locator, select audio input and output devices, and select your transmitter power in dBm. (See Appendix A for a Watts-to-dBm conversion table.)
Can WSPR track planes?
1. Does WSPR work with regard to detecting and tracking aircraft? WSPR can be used to detect and track aircraft and detect spacecraft or rocket launches or even volcano eruptions. It is possible to use WSPR at any time, where there are good radio transmission conditions.
What power does WSPR use?
The WSPR protocol is effective at signal-to-noise ratios as low as –28 dB in a 2500 Hz bandwidth, some 10 to 15 dB below the threshold of audibility. On most bands, typical WSPR power levels are 5 W or less — sometimes a lot less.
