Unid FSK 55Bd/500

heard on 13390.0 KHz/USB on 15 Januray, and monitored from 1320z to 1400z with reversals, this signal has a speed of 55 baud and 500 Hz shift. That frequency is commonly used by Russian/CIS Military with transmissions in Moroz-1A (and FSK/50/850) and FROST-1: the latter mode has been heard some years ago.
