CIS 81-81 single channel variant, FSK 40.5Bd/500Hz


this is a single channel variant of CIS T-206-3M (3M1) modem that operates at a speed of 81 Baud in case of two stations are worked (two distinct channels). It's a quite "old" system, most likely in use by some ex USSR republic. 
The recordered transmission has been copied on 08195.0 KHz (cf) during an idling cycle.
