Yes, MX is ok.

BEE/36-50 is a Russian Navy synchronous bit stream system. Traffic is most often
found running at 50bd but some 100bd signals have been found as well. The system
has no apparent ACF (ACF=0) and then idles with 36 bd (ACF=2). As the traffic
switches from 36bd to 50bd a preamble can be detected running with ACF=70. The
system appears to be synchronous with 1 stop bit and common shifts of 85Hz,
125Hz, 250Hz and sometimes 500Hz having been recorded. The CIS name for this
system is T600.

Cheers,

Ary
