WSJT-X – Weak Signal Communication, by K1JT – offers specific digital protocols optimized for EME (moonbounce), meteor scatter, and ionospheric scatter, at VHF/UHF, as well as for LF, MF, and HF propagation. The program can decode fraction-of-a-second signals reflected from ionized meteor trails and steady signals more than 10 dB below the audible threshold. WSJT-X incorporates nearly all popular capabilities of programs WSJT and WSPR, while adding comprehensive rig control and many other features. Open-source, download latest version for Windows, Linux, Macintosh OS X.
If you want to build a cw decoder without using other active components than an atmel 328 – Arduino UNO , then this is sure something for you.
