Digital Sound - MFSK

 

 

 

MFSK is similar to the commercial Piccolo system. MFSK is very good under poor propagation conditions. The usual variant of MFSK is MFSK 16, but other types such as MFSK 8 are in development, along with other similar modes to MFSK (such as Domino). MFSK is sideband dependant, so you must have your receiver set to the correct sideband in order to decode it properly. Also tuning is quite critical, although AFC helps somewhat. The top image is of an MFSK16 signal and the lower image is of an MFSK32 signal (which as you can see is nearly 500Hz wide, twice as wide as an MFSK16 signal).
