 WSJT-X implements amateur radio communication protocols or "modes" called FT4,
 FT8, JT4, JT9, JT65, QRA64, ISCAT, MSK144, and WSPR, as well as one called
 Echo for detecting and measuring your own radio signals reflected from the
 Moon. These modes were all designed for making reliable, confirmed QSOs under
 extreme weak-signal conditions.
