WSJT
Weak signal ham radio communication
...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 They are superseded by WSJT-X.
