Wsjt

Weak signal ham radio communication package

WSJT “Weak Signal Communication, by K1JT” offers specific digital protocols optimized for meteor scatter, ionospheric scatter, and EME moonbounce at VHF/UHF, as well as HF skywave propagation. The program can decode fraction-of-a-second signals reflected from ionized meteor trails and steady signals 10 dB below the audible threshold.
