Baudot FSK 100Bd/500 (unid Rus Gov/Mil)

Interesting async ITA2 5N1.5 FSK 100Bd/500 tuned on 11019.0 Khz some days ago. Once demodulated, the content consists of (off-line) encrypted 5LGs groups. Note also the slight deviation of the speed.

The transmission ends with the FSK-MORSE op-chat "CFM QRQ 100 QBN K": almost surely Russian Gov/Mil users.

Same 5LGs format and 5N1.5 framing was found in the reception reported in this post, with the difference that the latter has a speed of 50 Baud.
