two interesting MFSK catches

1) MFSK-66 (33+33) 40Bd/40 (presumed)

Transmission heard on 9122.0 KHz/usb on 20 November, 0832z. It looks like they use 2-tones x symbol and a manipulation speed of 40 Bd (Fig. 1). Dividing the spectrum into two equal parts gives a grid of 33 tones, 40Hz spaced, with the expected symbol rate of 40Bd (Fig. 2): this is why I defined the signal as MFSK 33+33 40Bd/40Hz, but I could be wrong. Likely Russian users.

2) 19KHz wide MFSK-17 33.3Bd/1200Hz

Transmission heard on 13386.0 KHz/usb (centered on ~ 13397 KHz) on 20 November, 1156z. Never meet a such wide band MFSK waveform.
