sdr-wspr

A WSPR receiver/decoder using libsdr

A WSPR ((Weak Signal Propagation Reporter) receiver/decoder using libsdr. WSPR is a technique (actually the name of a software) to probe the propagation conditions in various amateur radio bands. Each station participating, sends its call sign, location and output power using a very slow (about 1.5 Baud) but robust digital mode (usually called WSPR). This implementation embeds the original Fortran code into a libsdr processing node, allowing to assemble a WSPR receiver for various sources easily.
