The WSJT project implements software for amateur radio communication using state-of-the-art digital techniques. Typical applications involve "DXing" at LF, MF, HF, and VHF+ frequencies, including meteor scatter and EME ("moonbounce"). Major emphasis is placed on weak-signal techniques.
Summary Program Descriptions:
WSJT-X supports the communication protocols FST4, FT4, FT8, JT4, JT9, JT65, Q65, MSK144, WSPR, FST4W, and Echo, each optimized for different sorts of radio-wave propagation.
MAP65 and QMAP are designed for EME at VHF and higher frequencies. MAP65 provides a panoramic, polarization-matching receiver for the Q65 and JT65. modes. QMAP works together with WSJT-X to provide a panoramic receiver for Q65 modes covering a 90 kHz sub-band.
Programs WSJT and WSPR are interesting primarily for historical reasons. They are superseded by WSJT-X.
Features
- FT8 for general-purpose HF DXing
- FT4 for Contesting
- MSK144 for meteor scatter on VHF bands
- Q65 for special purposes including EME, ionospheric scatter, and trans-equatorial VHF propagation
- FST4 for LF and MF DXing with extremely weak signals
- WSPR and FST4W for propagation probes
- Echo for detecting your own echoes from the Moon
