MSK144 is a Minimum Shift Keying FSKFrequency-Shift Keying signal used for amateur radio meteor-scatter contacts. It transmits 144 bit long packets at a baudrate of 2000 bpsBits per second (bps) using frequencies 1000 and 2000 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz).. It is part of the WSJT-X suite, developed by Joe Taylor K1JT and others.
