MFSKMultiple Frequency Shift-Keying is a family of multi-frequency shift keying digital transmission modes. MFSKMultiple Frequency Shift-Keying-8 and MFSKMultiple Frequency Shift-Keying-16 are two well-known amateur radio modes. MFSK16 and MFSK8 were developed by Murray ZL1BPU and Nino IZ8BLY in 1999.
MFSKMultiple Frequency Shift-Keying-8 uses a set of 8 tones with the equal distance of 15.625 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz)., MFSKMultiple Frequency Shift-Keying-16 a set of 16 tones with the equal distance of 7.8125 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz).. The baudBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. rate of MFSKMultiple Frequency Shift-Keying-8 is 7.81 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. and that of MFSKMultiple Frequency Shift-Keying-16 is 15.625 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second..
